1ocec9 | How odds work if everything is random? | Odds basically tell you that if the exact same situation were to occur an infinite number of times, what portion of those times would lead to that specific result.
e.g. If you have the Ace of Hearts, King of Hearts, Queen of Hearts and Jack of Hearts in your hand and 48 shuffled cards in front of you, there is a 1 in 48 chance you will end up with a 10 of hearts for a Royal Flush. There is no way of guessing which card will come up next, but if you shuffled that deck drew a card (made note of which card it was, replaced it and repeat) millions of times, you would get the Royal Flush 1/48 of the time.
A pro would make that bet if it pays better than 48 times their money. They will only win 1/48 of the time, but if they get the chance to make that bet many many times in their lives, the rare win will make up for the cost of the losses. | bfc7b025-7988-4aa5-a9d1-0328349fa973 |
3oj00h | How do Jeopardy contestant's study? | Okay, so no Ken Jennings. How about Arthur Chu?
From [this](_URL_0_) article:
> Literally the first thing I did when I got the call was to ask myself, “Do I feel ready?” And the answer is, “Hell no, I don’t feel ready.” Thankfully, we live in the electronic age. So without having to use too much ingenuity or creativity, I just typed “Jeopardy! strategy” and “Jeopardy! studying” into Google, and lo and behold…
> Jeopardy! has been around for 30 years. All of the advice about how to study for Jeopardy! and how to play Jeopardy! has already been written. There’s a community online, called the J-board, of past Jeopardy! contestants and fans who just talk about this all the time. So I absorbed a lot of strategies from the greats. One of them was Roger Craig, who won a couple years ago and who broke the one-day total winnings record. He’s brilliant. He is a computer scientist, and he actually combed through an archive of past Jeopardy! games using an algorithm that scrapes all the clues out and figured out what the most common categories were, what the most common high-value categories were. Then he compared it to his own performance using flashcards to tell him where his most important weak spots were.
> Jeopardy! feels like it can be anything, but most of the really random clues come in the first round. The higher-value clues in Double Jeopardy are much more limited. They’re much more about traditional academic knowledge, things that a gentleman and a scholar is supposed to know, like history, geography, literature. And Final Jeopardy is often really focused on Americana. They love state capitals, state nicknames, U.S. presidential facts.
> You can’t possibly learn everything you need to know to get a perfect score, but to greatly increase your chance of winning, there are a few finite sets of knowledge that you actually can memorize. You can memorize what all the state capitals and all the world capitals are. You can find a list of all the official state nicknames and memorize those. And once you’ve done that, because those things come up over and over again, you’ve given yourself a big advantage.
> There’s a program that Roger Craig recommended, that I ended up using as well, called Anki. It’s a free program, and it uses what they call space repetition, which is an algorithm that keeps track of how well you do on flashcards and focuses on giving you the flashcards that give you the most trouble at regular intervals. So you boost your knowledge where you need help the most. I’m not a computer scientist, so unlike Roger Craig, I didn’t have a super scientific way of judging what I needed to know. I just looked at his comments. “Oh, you need to know about Nobel Prize-winning literature writers. You need to know about U.S. presidential facts.” And then I just put together a little study guide and committed to it. I started doing that every night instead of going out with friends or acknowledging my wife. | 1f7f7a90-47b8-47e4-8513-9d11f8be327b |
1m3lq8 | how can i press my stomach out? | The mechanism for inhaling is using your diaphragm to basically pull down, creating negative pressure in your lungs. When you inhale deeply to cause your abdomen to protrude, you relax your abdominal muscles and your diaphragm pushes down slightly on your abdominal organs, mostly your intestines, causing your abdomen to stick out.

34o46i | What would be the simplest way to "unplug" the internet, causing total shut down by means of disabling hardware? | Like, in your house? Or the whole thing?
In your house, just unplug the cable between the router and the modem.
The Internet as a whole is so resilient (it was intended to survive nuclear strikes) that it would be extraordinarily difficult. Global thermonuclear war might do it. | 61913e7d-ebe2-4d29-80f7-d8e253993cc9 |

2jbcql | What is homeopathy? | It's basically a magic potion with nothing in it. The idea is that you take a bit of something that causes the symptoms you want (say, some caffeine to make a sleeping pill, because caffeine causes you to stay awake), add it to water, do a magical ritual involving shaking the thing in certain directions a specific number of times. Then you take a tiny bit of the solution you've made, and put that into another container of water, and repeat the ritual. Now you have a tenth or a hundredth the caffeine you had the last time around. Do this a bunch of times until the solution has diluted all the stuff out of it completely, and you have nothing but shaken water remaining. Now you have a homeopathic medication.
The reason that people make fun of it is that it's so utterly absurd. A lot of people seem to be under the mistaken impression that it's some form of herbal medicine or something. It isn't. It's a form of ritual magic that in the end gives you a potion consisting of no medicinal ingredients whatsoever. | d79150bd-61c1-4538-bcdb-6a4b215e7d90 |
2c3ayl | How my wife and kids would go about inheriting things that are only in my name like bank accounts, house, ect.. | By default, after you die, everything will go to your legal next of kin. That person (or persons) is defined in this order, and if you don't have a living member of each group, it passes to the next one down:
Spouse
Children
Parents
Siblings
I believe that next comes grandkids, then grandparents, but don't quote me on that.
So if you don't have a spouse, but you have 3 kids and 2 parents living, your property would be split between your kids by default. And they'd inherit debts and things as well.
A will exists to change these defaults. Say you have a spouse, but you still want to make sure that certain things go to your kids, your will would enumerate "Hey, my kids get this, this and this, and my spouse gets whatever I didn't list." | f44549d5-9d31-4878-8564-8141bba8175c |
2brqk0 | What is my all carbs/protein diet doing for me? | Weight gain is dependent on calories in and calories burned. It doesn't matter where you're getting those calories from, if you burn them all through activity and lifestyle, then you're not going to put on weight. Olympic Swimmer Michael Phelps ate somewhere around 2000 Calories for breakfast (remember watching a documentary - his breakfast had eggs, bacon, sausages, waffles with syrup, etc).
My only concern about your diet would be that your lack of fruits and vegetables could mean you're risking various vitamin deficiencies such as Vitamin C, A, B12, K, etc. Not to mention you might not be getting that much fibre and depending on what exactly it is you eat, your cholesterol level could suffer. | c8a39870-bb40-42d4-9bcf-dcff5471363b |
3pu3uy | What ultimately stops you from jumping higher on a trampoline? | Diminishing returns.
The first time you jump on a trampoline, the only real force pushing you upward is coming from your legs.
On the next bounce, the trampoline converts a bunch of your downward momentum into upward momentum and helps push you back up into the air. If you push off again with your legs as that's happening, you will go even higher than you did the first time.
That means on the next bounce, you have even more downward momentum that the trampoline will convert into upward momentum for you (because you're falling from a higher distance and picking up more speed on the way down).
This works the first few times, but eventually you hit a point where you're already being pushed up into the air so quickly each time, your legs can't really do anything significant to help. | 23493c9b-d5c1-48f7-88d9-158cd2e52caf |
6qc4hs | Are calories just calories? Is it the same if you get a calorie from a fizzy drink or a piece of fruit or a slice of potato or a bit of cheese? | Yes, a calorie is a calorie, source is largely irrelevant, but that doesn't necessarily mean your body will react the same way. The input isn't different, but the output can be.
A simplistic analogy might be to consider getting punched with a certain measure of force (say 5 newtons). If you got punched like this in a boxing match, or in a tense situation on the street, it might neither surprise you much, nor would it hurt. If however, your mother or significant other hit you with the same level of force, you might end up massively more shocked, noticing it far more etc. In the same way whilst the force (calories) of an input will always be the same, the way your body reacts to the input will vary depending on its local environment - is it currently undergoing severe starvation, do you have a metabolic disease, are you middle aged etc. The local environment your body finds itself in can influence how it reacts to a calorie. This can be influenced by, amongst other things, the food you eat. So calories from fizzy drinks, whilst theoretically the same as other calories, might be treated differently by the body than a calorie from a piece of fruit, because of knock on effects from consuming a fizzy drink. The calories themselves aren't different but the method of administration can alter the reaction your body has to it. There are probably additional effects (albeit not particularly large) depending on things such as whether you have just exercised, how easily digestible the food is, current energy/glucose levels etc, or even your own personal biological quirks that influence how your body operates. Most of this stuff is relatively small scale though, and not worth worrying about at an individual level.

50j4ti | What can I do as a single individual to get Gary Johnson in the debates? | You could phone bank, donate to his campaign, that sort of thing.
The question you should be asking yourself is why you want Gary Johnson in the debates. His economic policies are frankly terrible. He thinks that socialized medicine is a bad thing, when it's been proven to be the superior system in every measure except 5 year cancer survival rate. He's courted anti-vaxxers, a movement I would like to point out quite literally kills children.
Sure, it would be nice to have alternate voices on the campaign trail. But I would prefer to have sane ones rather than crazy ones. | 63395e19-4adb-49f1-9656-f66649bf693d |
nbzoj | (or 18): Indefinite Detention Act | The portion everyone's worried about basically states that if someone is accused or suspected of being a terrorist the US government can detain (lock up) them indefinitely regardless of whether or not they are an American citizen. This is a big deal because, in addition to reminding everyone of the Red Scare in the 50s, it is a direct violation of the bill of rights, specifically the fourth amendment.
> Fourth Amendment – Protection from unreasonable search and seizure.
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized. --Wikipedia
Basically without a warrant, they cannot arrest you unless they see you committing the crime. This would remove that protection without modifying the constitution. In any sane environment it would immediately be thrown out by the Supreme Court as a violation of the constitution, but that its gotten this far to being passed is extremely worrying in and of itself.
TL;DR: If the government doesn't like what you are saying/doing (OWS) they can 'suspect' you of terrorism, or of planning terrorism, or having vague ties to terrorism, and detain you indefinitely behind bars.
Or at least that's my understanding.
Edit: Personally the distinction in the past few years that the constitution only protects American citizens and that for anyone else we can even ignore the Geneva convention if we feel like it is just as, if not more worrisome. Who the hell thinks like that. I don't care if he's British he's still human. | c677b434-4bfa-4962-af09-df923e9f64c9 |
42c3op | Why do computer telephone response systems always ask me to type a bunch of info, then transfer me to a human who asks for the exact same info? | I used to work for costumer service and we do this to make it an unpleasant experience for the costumer so that they never call again.
It's the same concept as those In-mail rebates that tend to be annoying to complete.
That's why I ended up quitting. I didn't like the whole idea of treating the customers bad. | 78fc0e99-e262-4e19-8b4d-93af56887f8f |
4jzzot | Why is it that lakes/ponds around the world have fairly similar fish, instead of them each having their own unique species of fish like land ecosystems do for animals? | The water in the lake came from somewhere. Most lakes are fed by rivers and streams, or were originally parts of a river network as is the case with [oxbow lakes.](_URL_0_)
A lake that was completely isolated from any other sources of water would eventually see evolutionary divergence if it had unique stressors, but there aren't many, if any, lakes like that, at least aboveground.
Also a lot of lake and river fisheries are stocked by humans. Like, you'll find largemouth bass in a lot of fisheries around the world, it's especially popular in Japan, but largemouth bass are only native to North America. They were artificially introduced to fisheries elsewhere. | 2663e337-b638-4c20-8bb2-3126bae92b43 |
4opi3t | How bars or clubs charge huge crowds of people randomly ordering drinks. | people either start a tab or they pay up front. it's part of a bartender's job to make sure they get paid for their goods/services. i'm sure some bars and bartenders will allow regulars to get away without paying upfront in certain scenarios, but that really depends on the business and employees. | db785d57-ef98-4140-a20f-0394f78a22e5 |
3uu7r2 | What is Operator Overloading | In programming operator overloading is when you take a simple mathematical or logical operator like + or ! and define what that means. It's generally only applied to user-defined types/classes/objects, as the definition of these operators tends to be predefined for numbers etc.
Imagine you have an object X, only you the programmer can define what it means to add two X objects together. X might represent a list of objects in which case the result would be an X representing the concatenation of both lists. X might represent a mathematical vector, so the result would be an X representing a vector that's the result of adding the two argument vectors together.
The best example for this is C++'s [std::string](_URL_1_) which has an operator+ that takes two strings and returns the string representing the concatenation of the two arguments.
Some languages (again using C++ as an example) have conversion operators as well, such as [operator bool on std::shared_ptr](_URL_0_) which defines how to convert a shared_ptr to a boolean for use with (for example) `if(!myptr){}` or `if(myptr){}` expressions, but otherwise works in a similar way.
Different operators take different numbers of arguments, e.g. ! is a unary operator, takes 1 argument, + / - * are all binary operators and take two, and so on.
Edit: ! is a unary operator not a binary. I knew what I meant ;-) | 170b1dff-2722-4560-81b8-8068fb696f5f |
6hxm67 | What is vanity sizing in clothing? | In fashion, womens' fashions in particular, people want to believe they are thinner than they actually are, and if you get north of a size 6, which is still quit thin, you are often looked down upon for being too fat. Some designers don't even make their clothes in the higher sizes.
To make consumers feel better and buy more, some brands cheat a little bit on the size, so what is labelled as a size 6 is closer to a size 8. Other brands, to maintain more exclusivity and to ensure only the thinnest people wear their clothes, cheat the other direction, so a size 6 is more of a size 4.
> How do I properly size clothes online that aren't in vanity sizing?
* measure yourself and go by inches rather than size
* check the return policy...a retailer with more friendly online return policy is going to be more confident in their sizing
* be honest with yourself...vanity sizing works because people want to insist they are a smaller size than the actually are
* shop brands with a strong online presence, and be extra careful going through a reseller or a department store that is just carrying the brand
* read reviews...sizing is one of the first topics people will mention | d0747f36-61f9-4b21-8792-8d1b5a60e831 |
1r7qm7 | Why group mentality is so powerful | Human nature to belong and conform to social groups, empathy, and natural fear of exclusion.
It's kind of instinctual, that's why the weak minded are susceptible to group mentality. Case in point: Reddit. | 0f7dbda3-1157-4276-aa10-cca9ea3ccf11 |
3drimk | Why can't horses get rid of flies on their eyes? | They blink, the fly flies off, goes about two feet, pulls a u-turn and goes back to the eye.
They can get rid of them, but they can't keep them away.
Really, the ancestor to the domestic horse wouldn't have had this problem because they didn't live in stables.
It's the domestic horse's enclosure that attracts the flies, gives them a breeding ground, and traps the horse so it can't get away.
It wouldn't be a problem if they didn't live in the environment we put them in. | a25bccd5-63e7-41c2-b27e-1d315638a0c9 |
3x24zh | If each pixel is merely a combination of a red, blue, or green light, why don't colorblind people who can, for example, not see red or green colors, only see blue on computer monitors? | It's not that colour-blind people can't see red or green. They can see them both fine; they just can't tell them apart. | 1c60af77-04db-4dbe-930e-32018ebab049 |
1yvn6n | What is happening after a workout in our body? | As I understand it
In a workout with decent intensity(a lot of weight being moved/force being generated) your body releases testosterone and a pulse of growth hormone. After about an hour this pulse gives way to stress hormones like cortisol. During this time you deplete nutrients from the muscles, stress your bones, and usually slightly damage the muscle fibers. All these stimuli lead to your body adapting those systems to tolerate the strain you put on them. So in the days following the workout, your bones would get denser, muscles would be replenished(for most people, about 48-60 hours after a session is a period of supercompensation in terms of stored muscle energy, the optimal time to lift again) and if you are eating in caloric excess OR you are a beginner, the muscles would grow slightly. I say caloric excess or beginner because at those times your body adapts very quickly to stresses. You will be incredibly sore, but as a novice you might be able to add 30 pounds to your maximum squat in 3 sessions. When just starting out, your body is panicking trying to adjust, so it pulls energy from your fat stores to supply the important tissues, the muscles Also soreness/physical pain is not a sign of an effective workout. | 21e6792a-5aee-4f09-b1f1-f269b33cc164 |
7iyd1n | What is it like playing intense sport (or exercise) in freezing weather? | Down to -5 no major differences, except you can loose heat rapidly if you stop moving, layering your clothing is important to manage your heat/sweat.
-5 to -20 your get an iron taste in your throat/mouth when breathing heavily, otherwise same as above.
Below -20 breathing becomes painful, your nose can freeze, your sweat freezes before evaporating. Layering changes from important to critical as these are the templates where sweating can lead to death. | cd301520-d454-42d1-9f87-5dfb3b1d7397 |
3x3mlz | what ever happened to Dane Cook? | Credit to /u/noposters for this answer: What people don't realize about Dane Cook is that he was on a mega run before Harmful if Swallowed blew up. Even before his comedy central half hour, he was the highest paid comedian touring colleges at that time (not the highest paid in general, but he swooped in when Sandler stopped doing colleges and took those gigs at Sandler's rate). Once his albums blew up, he played MSG, etc. he tried to make the transition into film. His films flopped, and simultaneously both his parents died and it was discovered that his brother/business manager had stolen 50million dollars from him (never recovered). With all those things coming together, he took a bunch of time off. When he came back, tastes had changed and he no longer had the traction he'd had years earlier. He tried to make some comeback appearances but wound up generating controversy by trashing the audience at one of his shows at the Laugh Factory (TJ Miller and others brutalized him on twitter for his behavior). Since then he's appeared here and there in LA and done some voiceover work, but for the most part he keeps a low profile. He's also alienated a lot of people in the NY comedy community for playing up his relationship with Patrice O'Neal in interviews when the two were, in fact, not close | 676ac3fd-7ce4-4eac-8f8c-03646adf411e |
3yrw53 | The Hateful Eight in 70mm, is there no way to replicate so every theatre gets that "visual effect"? | Gonna get a little technical:
The movie has a digital equivalence of around 8192x2968 (assuming a 4K equivalence for regular 4-perf 35mm). I don't know of any theater that has a projector above 4K, many are even at 2K (2048x1080, almost the same as regular 1920x1080, as most movies are 2K).
So, seeing it in a theater with 4K projection is the next best thing (at basically 50% the "resolution").
Movies like Interstellar, The Dark Knight, Star Wars Ep VII (only one scene though), etc. are even bigger because they are 70mm IMAX, which is around 11800x8192. I saw both Interstellar and Star Wars Ep VII in this format and it what great, Interstellar took the cake though in terms of how amazing it was visually/immersively. | f8cddcc3-d273-4014-8e00-da53c8cf0270 |
1jv6t7 | Calvinism | John Calvin was a theologian who was part of the reformation. His theology became known as Calvinism.
Basically Calvinism is boiled down to the TULIP beliefs.
* T - Total Depravity - All parts of man are affected by sin
* U - Unconditional Election - We are saved by Christ without any conditions. We do not earn it, it is completely a gift.
* L - Limited Atonement - Jesus died on the cross only for those who follow Him. His atonement for sins was not for everyone.
* I - Irresistible Grace - If God wants you to follow Him you can't resist the call.
* P - Perseverance of the Saints -Once saved always saved. You can't lose your salvation.
Not every Calvinist agrees with all 5 points. In fact, some say Calvin didn't believe in all of them (the term TULIP was made up after he died) but these are the basic theological points.
**tl;dr - There are two main camps of Christian theology. Men are in control and choose to follow God (Arminianism) and God is in control and chooses who follows Him (Calvinism).** | 2166ecd6-a262-417d-ac78-9cfefe59db85 |

6x2ldn | Why does tiredness feel as though it comes in waves? | Biorhythms. Your body has cycles: breathing, heartbeat, blinking, even which nostril you use. Your wakefulness/tiredness is also cyclic. | f36157a8-b543-4c3b-8532-1a279485d346 |
2yahdf | how does your brain produce a coloured image through staring at a negative? | These are called afterimages and their existence is covered by something called Opponent Process Theory.
Basically, you have 3 types of cells in your eye that detect color. They are called cones. One cone is sensitive to the wavelength of light we associate with "red", another to "green", and another to "blue" light. I put the color names in quotes because you must understand that COLOR DOES NOT EXIST IN THE OUTSIDE WORLD, YOUR BRAIN MAKES IT. This is itself is mindblowing but I promise it is true.
Anyway, the cells get tired after looking at the same thing for too long (both the cones I mentioned and other cells further into your brain). They are a bit like a rubber band that gets stretched out the more it sees a certain color, and the more it stretches the more it really really wants to snap back. Stretching makes you see one color (say, red), while snapping back makes you see another color (green).
The deeper cells in your brain are arranged in 3 opponent pairs: red-green, blue-yellow, and black-white. So, the more of you see of red, the more the opposite wants to come out. Same with the other colors.
(Neurologically, this occurs because one color is produced by the cells getting excited and building up a particular chemical that tells your brain to produce red. This is an anabolic, or constructive, process. The opposite color is produced by the cells getting inhibited and the chemical being destroyed, which is a catabolic or destructive process. Again, it all works because these chemicals instruct your brain to produce the color image - your brain makes the actual color experience not the world). | fce8026f-f246-4638-8b16-5d98625f9901 |
2uxanc | Why are most passwords hidden on-screen by default when you type them, but WIFI passwords are not? | Most on screen passwords are hidden in-case you have any shoulder surfers(people watching you type over your shoulder). WiFi passwords give you the option to either hide or show, in my opinion as WiFi passwords are normally longer than other account passwords they can be hard to make sure your typing correctly without seeing it | 14284308-35e1-468d-8d4d-625e1ddfa13c |
15shd5 | Why does time use the number 60? | 60 is easy to divide cleanly in multiple ways, and a number based on 60, such as the number of degrees in a circle, can be divided yet more ways. 60 can be divided by 1,2,3,4,5,6,10,12,15,20,30 and itself. This provides many easy-to-reckon, useful fractions. In the days before pocket calculators, slide rules, Napier's Bones, etc. this made life simpler. | d1eef01d-ec85-467a-be87-ae02b1178c64 |
10hsdv | - the Monsanto controversy | Worries about engineered foods aside, a lot of people have a huge problem with Monsanto's business model...
They use patent law to force farmers to buy seed from them every year. The farmers do not own the seeds that are created by the plants they are growing - Monsanto has the *patent* on the seed DNA. So they can't just buy seed one time and then create their own seeds from then on, as you might believe would be common sense. They even go so far as to sue farmers that *accidentally* grow Monsanto plants; from seeds blown over from a neighbor's field, for example. Monsanto charges a lot for the seed. They are definitely pushing the extremes of patent law to make as much money as possible.
Now, having said that, Monsanto invented some pretty cool seed. It creates its own pesticide, for example. So, by using it, you save money on spraying your crops. That's certainly worth something. People just disagree on how Monsanto should be compensated for what they've done. Obviously, a large corporation like Monsanto would like to squeeze as much money as possible from whoever they can. They aren't trying to work out a "fair deal" for what they've accomplished - they're just trying to maximize profit.
It's easy for people to envision a future (maybe not so distant) where corporations own the rights to everything we grow (through DNA patents) and charge a lot to farmers (and ultimately consumers) for licenses to grow crops. | c0f274a1-c23d-48ac-8ae5-cd26b7817dee |
7bne7n | The true difference between i5 and i7 processors | The biggest difference between i5 and i7 processors is the number of concurrent threads they can handle. i7 processors are equipped with hyperthreading, which is a technology that allows a single processor core to do almost as much work as two separate cores.
Imagine a single processor core is like a chef. Both the current generation i5 and i7 processors have 6 chefs. The chef receives a set of ingredients and a recipe, and lays it all out on the table. This table is like a processor's cache - it's the memory that the processor has to work with.
The chef then prepares the meals, and puts them back on the table. Now, the chef has to wait for the waiters to clean up the table and bring new ingredients. The chef busts out his phone and takes a break while this happens.
Hyperthreading is like giving the chef 2 tables. Now, while the chef is cooking one set of meals from table A, the staff can clear table B and bring new ingredients. Once table A is complete, table B is ready for cooking. The chef can now switch back and forth between the two tables and have almost no down time.
One of the other big differences is the size of the table - that is, the size of the cache. i7's generally have larger cache sizes than i5's do, which can help them do more work in the same amount of time.
Edit: Just realized that I didn't really help you make a decision. :)
Having more cores is only useful in certain situations. When the work can be 'parallelized,' - that is, divided up such that the result from one chunk of work doesn't depend on the result of the previous chunk of work - then being able to handle more concurrent threads is a very good thing.
For example, if you're building a house, you need to pour the foundation before you can set up framing, and you need to set up framing before you can run electrical and plumbing lines, and you need to set up electrical and plumbing before you can put up drywall, etc. It's not possible to split a task like that up into several chunks and do them all simultaneously.
If you're building 20 houses, you can pour all 20 foundations at once, set up all 20 frames at once, etc. The result of building part of one house doesn't depend on the construction of other houses.
To a CPU, gaming is often like building a house. The calculations for one moment in the game will influence subsequent moments in the game, so it's not possible to divide the work up among several processor cores.
Video editing, on the other hand is highly parallelizable. Rendering frame #25 doesn't usually depend on the results of rendering frame #20, so software can divide that work up and distribute it across the processing cores.
TL:DR; Gaming doesn't usually benefit as much from multiple processing cores. Results will definitely vary from game to game though. Video editing often does benefit from more processing cores, so you can reduce rendering time significantly by using an i7 instead of an i5. | d9b575df-2432-4d67-b3dd-e0add3f90b73 |
5nnlt1 | Why does water taste bitter after eating pineapples? | When the water hits your taste buds, they are stimulated a little. The problem is they have been overloaded with sugar and acid, thus they are temporarily unable to *report* sugar and acid at that moment. Therefore they report the only thing left: alkaline (bitter) taste.
Add that to the fact that most water has dissolved minerals in it that make it ever-so-slightly alkaline. | 7527138c-b899-43e3-aaa1-3ee3ec3dca39 |
7loatb | What does fuel stabilizer do to gasoline? | Gasoline should keep indefinitely if stored properly.
However, stabilisers can be useful if fuel is stored incorrectly, for example, in partially full tanks of small equipment. The larger tanks in modern cars are carefully designed to protect fuel from air and evaporation.
Gasoline molecules can evaporate if the tank is not securely closed - a stabiliser won't do anything for that.
Gasoline molecules can oxidise by exposure to oxygen - a fuel stabiliser can contain an anti-oxidant to absorb the oxygen, and neutralise the free radicals accelerate the oxidation reaction.
Gasoline may contain traces of metal from manufacture/processing or from metal storage tanks. Certain metals can act as catalysts and cause the gasoline molecules to polymerise into sludge. Metal deactivator additives can absorb and neutralise the catalytic effect of metal contamination.
Gasoline may contain large quantities of ethanol to meet biofuel targets by governments. If stored open to the air, the ethanol can absorb water from the air, and this can cause the water/ethanol mix to separate from the gasoline. By adding a different alcohol (methanol or isopropanol), the water/alcohol mix doesn't separate as easily.
All these problems can be avoided if gasoline is stored in a tightly sealed plastic tank with only the minimum amount of air for an expansion space, as high quality gasolines will come with metal deactivators already added to neutralised contamination at the refinery. | 056ef704-c071-43b5-ab72-7cd27c4d51c6 |

js0eq | how a drug goes from needing a prescription to being able to buy it without a prescription | Like you're five? Because the grownups who make the drug (Sanofi) showed the grownups who regulate the drug (the Food and Drug Administration) that the drug is safe enough to take without needing the advice from a doctor. The drug itself does the same thing only now you don't need a prescription from the doctor. People get easier access the the medicine, the drug company gets to sell a lot more drugs, and pharmacies make more money because they're selling more OTC items.

5b6c5j | How do cars calculate speed and preview it on the speedometer? | **NOT ELI5**
The car's driveshaft also powers a *speedometer cable*, which spins a magnet around at the same speed inside the *speed cup*. This magnet rotates continually in an equal direction. This spinning creates a fluctuating magnetic field. The laws of electromagnetism dictate that a current must therefore flow inside this cup. This current causes the speed cup to also rotate. It attempts to catch up with the speed of the magnet. a *hairspring* stops this, so it only rotates a little. This small motion moves the dial on the speedometer a little. The stronger the current, the faster the cup rotates, the further the speedometer's dial moves.
& nbsp;
**ELI5**
The driveshaft powers a speedometer cable, which leads to a magnet rotating inside a cup. A current is generated, and the cup tries to rotate also. A spring limits this, moving the dial. More current = more speed = dial moves further. | b483b909-f831-41d4-98c1-32d44ea79429 |
2jzsw2 | If Western governments are worried about their citizens fighting for Daesh (the Islamic State) and returning to participate in terrorist activities, why do they have to "monitor" them when they come back rather than arrest them? | In most western democracies you can't arrest someone just because the government doesn't like their political views (there are some exceptions to this rule but in general it holds). You have to be able to prove that they have committed some kind of crime in order to arrest them.
Almost by definition someone who has joined up with Da'esh/IS will have "fallen"off the radar" of western security forces. They'll know they joined up but it will be much harder to prove that they actually fought against western interests, which would be necessary to instigate a charge of treason or similar.
So the best we can do is have the security services "watch" them very closely, and if they look like they're about to commit any kind of crime then they can be pulled in. | 2b63bb86-65b2-4773-941d-9150539415f8 |

3dw4ox | Why is it, that even though I genuinely love Whiskey, I shudder nearly every time I drink some? | Your conscious brain loves it, but your subconscious brain realizes that alcohol is inherently bad for the body, and causes you to shudder.

64b1vp | Why do our eyes not see color on the edge of our peripheral vision? | The cone cells that detect color aren't very good at low light or motion detection.
Since motion detection is more important at the periphery than color (does it really matter what color that sabre toothed tiger is?) we evolved to pack mostly rods and few cones in the corners.
Your brain remembers what colors things are and will attempt to color in the peripheral vision so you don't usually notice that it's basically grayscale. | 60d42749-9fb1-4077-9fa7-e3ee26cbfa20 |
1moxcs | Why is it when I drink a glass of liquid I urinate at least twice as much back out? | Your bladder only sends the "time to pee" message to your brain when it reaches a certain level of fullness. So the amount you pee out doesn't just represent the glass of water you just drank, but all of the water you have drank since the last time you peed plus the water your body needed to dissolve the waste products it excretes in urine (urea, creatine and some other compounds). | e6b0dccb-1c59-424f-a71e-5af5e29b53f2 |
676bz1 | What prevents DNA from getting tangled? | Proteins!
There are *many, many* proteins in your body that have a specific job of keeping your DNA tangled/condensed the perfect amount. There are topoisomerases, a family of proteins, that specifically twist/untwist your DNA to introduce/remove "supercoils" (like what would happn when you twist an elastic band) to condense it or expand it. There are some proteins like histones to which the DNA will almost always be attached. The histones kind of serve as a backbone for the DNA; a place for the DNA to organize itself.
Of course, this is just the very basic level of proteins. There are many more proteins and ways to organize DNA. It's always proteins! | 43f1deff-633f-4ef7-b920-206ad3f61a0f |
5v4xi7 | Why does the tray in a microwave rotate? | Because there are hot and cooler spots due to the way the microwaves reflect around inside the oven. Rotating the food attempts to distribute the heat in the food more evenly. | 677d4ff5-5b03-4643-8e63-49e883da7266 |
3y7usk | why child support is based on income rather than what a child would need monthly. | Child support is partially based on income. It is also partially based on the number of children and their age, the cost of basic living expenses and school in that general area, and whether or not any special needs are present. Which sometimes leads to a very high ratio, but that is also something that can happen when both parents live with their children; not all jobs pay a wage that covers a child's reasonable expenses. That doesn't mean those expenses don't occur though. | c67f471e-0af7-4af8-a40d-88533f4da315 |

Also, he added in a bunch of CG aliens that didn't fit, put back in a deleted scene with Jabba the Hutt that wasn't necessary, added cheesy special effects to the Death Star explosion, added in a fucking song and dance number to Return of the Jedi, replaced the original ending of Jedi and added in Hayden Christiansen. He basically tinkered with it unnecessarily and added in a bunch of crappy looking CG aliens and effects.

1qg28u | Difference between computer virus, worm, and trojan horse | All of these are software programs.
Computer virus - the typical attribute here in a software program that makes it behave somewhat like a biological virus, is its ability to copy and replicate itself by "infecting" other software programs - i.e it attaches itself to these programs, either by infecting them as they are running in the memory of the computer or by accessing the disk and changing the file. When these infected programs are used, or copied to another computer, that computer becomes infected too. It also means, if you delete the virus or reboot the computer, running any of the infected programs will run the virus again and mean your computer is still infected.
Computer viruses tend to spread and infect via replication. As anti-virus programs appeared that could detect computer viruses, programmers added the ability for these programs to mutate as well - i.e to change their code in subtle ways that wouldn't change their function but would make code that looked for a specific pattern fail to spot them. In some way this is similar to the way viruses mutate to avoid an immune system - albeit it's more about the word "virus" being descriptive rather than actual parallels between the 2.
A trojan horse - the attribute here, is that it's a program that looks like it performs a specific function - maybe a game or something - but which hides inside it a program that performs another function (usually a malicious one) - the analogy here is, of course, with the [trojan horse legend](_URL_0_) about people hiding inside a "gift" in order to enter and destroy a city.
A computer worm differs from a virus in that it doesn't infect another program, but it operates as a standalone program. It does copy itself, replicate and spread by exploiting security weaknesses usually via a network. You can picture this as a program running on your computer, which detects other computers connected to yours, so it "moves" over the network, via whatever security holes exist, until it's running on the other computers...and it continues like that traversing across the network looking for machines to infect.
It's worth noting that although bugs or issues with any of the above methods of infecting a computer may cause computers to crash or other faults and usually take resources, it's not the above actions, from which viruses, worms and trojans get their name, that are necessarily the motives of whoever creates them (Although earlier examples often did nothing more than copy and infect as exercises in curiosity)
More typically, there is another piece of the software, called the 'payload' which is designed to actually do something malicious, like steal your passwords or sink your nuclear submarine. Payload coming from flight or launch vehicle terminology. | 36f1e86f-1c75-4002-b37d-4874a13d5818 |
3vfllb | Why does the media spend so much time covering the question of whether or not Jeb Bush can rise in the polls, but doesn't extend nearly that level of coverage to other non popular contestants? | Jeb Bush is considered (generally) the primary establishment candidate, which means he's expected to have significant political clout with the republican party. Alternatively, he's also a Bush, which means he's entangled in a lot of familial controversy, 'Bush Dynasty' 'Can George Bush's brother win after his unpopularity?' sort of stuff.
Both attract interest, which the media wants in order to get paid. | 4f4e2075-857f-4a76-9f1e-8fe610a709b6 |
28huk5 | The different between Sunni and Shi'ite Muslims. | Shi'ites think that leadership in Islam should be hereditary, and that Imams more or less represent the authority of the founder through his bloodline.
Sunnis think that leadership in Islam should be by some sort of democratic process, and you don't need to be a descendant of the founder to hold authority.
It started out that way when the movement had to decide on how to continue after the death of its founder. Pretty soon, through in-fighting and because that is the way things go in a closely knit community, everybody and his uncle also had an opinion that would be forced upon the community.

4mxv3z | Why did film become a synonym for movies when photography also used film? | It depends on the context, but I'll stick to your examples. People didn't view still photographs on photographic film. They needed to be printed on photographic paper. Slides are an exception, but they didn't get popular until later.
Motion picture film is negative and printed onto another piece of film to make a positive for viewing via a projector. Many people view magnified motion picture film, but most people never view still photo negatives.

387rob | The core beliefs of American political parties. | This is a difficult question, America is insanely vast. A Republican in New York is going to be much different from a republican in Texas. A democrat in California will be different from a democrat in Michigan. Any person that wants to run for major office with a likable chance of winning usually has to run under one of these two parties, recent example: Bernie Sanders.
The idea is Republican is generally more conservative, pushing for no economic regulation but social restrictions. Democrats are generally more Liberal pushing for zero social regulation but economic and business restrictions. | cbcc10a9-6075-4973-ae2b-75aa01a76397 |

66cih6 | Why when we are sick/have an infection does our body temperature go up, as in a fever? | Many infections grow best at particularly precise temperatures. Your body raises your temperature as a defense mechanism, slowing down the reproduction of the infectious agent and giving your own defenses a chance to 'catch up'. At the same time it enhances the ability of some of your body's defenders to move around more actively in their war. | f0ddd28e-4284-4c69-9e48-0632f3c3abd5 |
3dhi2h | Why do real almonds not taste like almond paste/flavoring? | The almond flavour you taste in almond paste, marzipan and so forth comes from an aromatic called benzaldehyde. This is found in *bitter* almonds, which also have a fairly hefty amount of cyanide; the latter is removed during the extraction of the benzaldehyde.
The almonds you eat in nut form are *sweet* almonds, which contain a much lower level of benzaldehyde, and, luckily enough, cyanide as well.
Benzaldehyde is also present in apricots, cherries, and peaches, which is why they all have similar taste profiles. | e2cb4736-a490-453c-933e-6405994a4d72 |

3ahe8n | When I swallow a pill, why is there sometimes a heavy feeling in the back of my throat? | I used to get that feeling a lot when I first started taking my daily pills. Turns out I wasn't getting the pill "stuck" in my throat exactly, but I was not swallowing them with enough water.
When someone swallows pills without proper salivation or lubricant the object can "scrape" itself on the back of your throat, leaving you with that heavy and sometimes painful feeling that doesn't go away for a while. It may feel like it's lodged in there, which could be possible, but it's most likely just pain from the pills contact.
Long story short, always drink water before and with pills. | d33d53c5-c9ae-4a8d-a01d-f0ddba32aec0 |
6wvrj6 | Why is Reddit valued at "only" ~$1.8 billion, when less popular sites (e.g. Twitter) are worth many times more? | Reddit isn't publicly traded (there hasn't been an IPO yet), so speculation can't inflate the value of the company like Twitter or Tesla.
A company is basically worth how much people are willing to pay for shares of it, but you can't buy shares in Reddit yet.

4w6xmi | How can there be a sex wage gap in the US if we've had the Equal Pay Law since 1960? | There's a bit of a misconception about the wage gap. For jobs in the exact same role with the exact same responsibilities, the wages are about the same. However, men tend to be more likely to be promoted to higher-paying positions. Women are also more likely than men to take extended time off or work part time while raising a family, meaning their careers are held back during that time. | b463de60-b6b2-4b9f-990d-80925f03d0c3 |
3tbt9h | Why/how does eye-makeup (even simple eyeliner/moderate mascara use) have such a dramatic impact on how attractive women are perceived? Why only women? - is it all just socialization? (Are we just conditioned to think that's attractive?) | Eye make-up is often used to extenuate the size, shape or colour of someone's eyes.
Your eyes can give away a huge amount about your current state - revealing indicators about your health, your energy levels, your age, your state of mind etc.
A good application of eye make-up could take tired, old eyes and transform them into bright, youthful eyes with energy. The difference is enormous visually because so much of human contact is face-to-face and the eyes are the focal point of the face. | f611bca1-65fe-44fc-8a51-3297249afd7c |
7clhj9 | How can electric motors for cars be small enough to fit into a car and relatively cheap while industrial electric motors with similar power and torque are the size of a kitchen and cost more than an electric car? | Industrial electric motors are meant to be run nearly 24/7 at higher loads and don't have to be portable, so size isn't usually a factor as much as keeping them cool, so they're built to shed excess heat better, and more surface are = more heat that can be transferred away.
on the other hand for cars, weight and size are bigger factors, and the motors in them will never be run full power all the time, so more effort is put into them to keep them smaller. Heat dissipation isn't as much of a problem either in a car as you can use the cars air flow to help keep things cool, whereas industrial motors don't usually sit in well ventilated areas. | f5d7bc43-9bc5-4ca7-9b31-d39c73a1c9f9 |

43bzmi | Why do American cities often have to take large public transport projects such as light rail and metro system to the voters but don't have to do the same for massive highway and road construction? | Large road projects usually exist to keep the existing road network running, or to improve its relation to the rest of the city. Bridges need to be retrofitted, underpasses capped, tarmac replaced. They may be big projects, but they're really necessary to keep the system functioning like it is.
A major public transportation network is an entirely new investment. If you don't do it, you don't it--there's no downside other than that you don't have the network. A comparable project would be the construction of an entirely new highway link (or in some cities, the removal of major highways), which is rare and nowadays often put to voters as well. Of note is that many major highway projects were initiated in a time when referendums for transportation were not as common. | 9fad1c3b-cf73-4b72-a71d-24c1f7b5b43d |

10xx7k | The new changes to paypal's policies, and why its bad for me. | The big one that's mentioned is the change that you can't join a class-action against paypal so I'll explain that.
Lawsuits are expensive. Even a little suit against your neighbor over cutting down your tree can rack up costs from court fees and time spent arguing the case. In a major court case involving a huge business, this gets even worse with the added time and expense of hiring a lawyer.
Generally speaking, a large corporation will have more money to throw at the court case than you do and can bog it down until you can't afford the costs anymore. Class action lawsuits are one of the defenses in the law against this. Instead of just representing yourself, you represent a whole group of people (a class) who were wronged by the corporation in the same way you were.
EXAMPLE:
Widget Works sells you a widget to trim your cat's fur. It sets the cat on fire and you sue for 200$ (cost of widget + damage to cat). Now, you can't afford to sue them and a lawyer won't do it for a cut of the reward. However, upon further research, you find that 10,000 other people had their cat set on fire by widgets. Although a cut of 200$ isn't enough for a lawyer, a cut of $2,000,000 is worth it. By filing a class action lawsuit of for yourself and those 10,000 people, you can actually find a lawyer to represent you. | d15436ba-615f-4c07-b1f4-3afe6a782a1c |
2mb88u | How is Canadian healthcare different from Obamacare? | Canadian healthcare is, more or less, single-payer. Basically, you pay a tax to the government and the government insures you.
American healthcare is a big old mess. We have single-payer for some people (Medicare), full-on nationalized healthcare for some (the Veterans' administration, where doctors are government employees), private insurance for many, and no insurance (fuck you and die) for some.
Obamacare is actually working--it's fixing some of the worst problems with private insurance and reducing the number of people with no insurance. But our health care system is still a big old mess. Obamacare didn't create the mess, but it does sort of freeze it in place.

7cfiri | Why do app developers like supercell release their updates/apps way earlier on one platform than the other? | If you're referring to the time gap between Android and iOS releases, the answer is because of Apple.
Things get on the Android market very easily and quickly, because the Android market is cool. Apple has dozens of excessive rules and guidelines that they strictly enforce, so they actually look through the app/code.

Police departments operate independently from one another. I have nothing to do with the department in the next town over, let alone across County or state lines.

6tesyr | If we were still at war with Nazi Germany, Nazi supporters would be tried for treason. Why now are Nazi groups aloud to persist, unchallenged by law? | There is a very fine balancing act between avoiding government censorship and persecution of political groups on the one hand, and allowing desctructive elements to fester until they become too big to deal with on the other.
If you give the government powers to imprison people for holding certain political beliefs, how is that fundamentally different from what the Gestapo did? And who gets to say exactly which political opinions are allowed and which are not?
Back in the Germany of the 1930s, the popular belief was that it was the Communists who were the dangerous, subversive elements, and the Nazis promised to deal with them. It was when the Reichstag building burned down -- apparently as part of a Communist plot, although nobody can ever be 100% sure of that -- that the Nazis were able to push through their Enabling Act, a kind of emergency legislation, ostensibly to eliminate this threat to society, but which in fact made it possible to effectively ban all other political parties and dismantle Germany's entire democratic system.
For obvious reasons, modern Germany is very keen to ensure that extremist political groups can never do such a thing ever again, and so they had to come up with a way to ban such organisations without giving a future government the power to eliminate all opposition in exactly the way the Nazis did.
Germany's approach takes on this form: first, the German constitution contains lots of written guarantees of certain basic human rights. Many clauses are subject to what's called an "eternity clause", meaning they can never be repealed or weakened for any reason whatever, and they must be included in any new constitution that succeeds the current one.
Then, there is a ban on any political party that is, in the language of German law, "antagonistic to the constitution". That is, if your political movement can be shown to be actively working towards undermining the constitution, it can be banned.
The bar is set quite high, though. The authorities have to gather a *lot* of evidence, and this often means infiltrating the movement. There was an embarrassing case a couple of years ago, when some agents had infiltrated such a movement so successfully, that they rose up through the ranks and some of them were partly responsible for the very policies that were supposed to be evidence of the party's anti-constitutional aims. (It's difficult to blame the agents -- after all, they really didn't want to break cover.)
Then the constitutional court has to study the evidence, and decide whether or not to withdraw the organisation's status as a political party.
But even if you ban the organisation, you can't change the minds of the individuals. They will simply regroup, and join or found a new party, taking care to ensure that in public at least, they stay on the right side of the law.
The real key to this, though, is not the nuclear option of suspending basic rights for certain classes of people. It seems to be education, and here Germany has an advantage. All German schoolchildren are taught about the rise of the Nazis and WW2, and in particular they are all made to visit a concentration camp. The message "Never again" is drummed into them from a very early age. | 3017cfb8-7e66-452c-8ed7-e54b89e360d4 |

yayj4 | The different branches of Christianity, and why they are no longer combated as heresy | In many Christian circles, this is the analogy that applies:
Imagine a target, with three rings. The center, the bullseye, are the core values. I call them "primaries". It's what defines Christianity. Without starting a debate, I'll say that some people disagree on what goes in the middle. These people we'd call heretics (an extreme example would be to say that Christians pray to Allah - obviously wrong religion).
In the next outer ring, the middle, we have "secondaries" - this contains issues like speaking in tongues, eating shellfish/pork, Saturday vs Sunday Sabbath, etc. We can disagree and have discussion on these, but it doesn't make you less Christian.
In the outermost ring, everything else falls. This would be issues like watching R-rate movies, wearing jewelry made of gold, and non-related topics like playing sports or driving race cars. We use our secondaries and primaries to express our outermost issues.
We have unity in primaries, liberty in secondaries, and charity in all.

The egg then will either expire or start to divide. If division is allowed to continue, the embryo may be able to be implanted into a host surrogate mother animal, and the clone then gestates as a normal embryo does. Gestation complete, it is born.
Tada, clone.
Typically, all the animal parts are the same animal, but not always. An example of a 12 day old experiment with cow egg and human nucleus happened, for example.

It is important to note that this does not guarantee a psychological/mental clone, but a physical one. The experiences of the clone, unless *exactly duplicated in every way to the original*, will mean the clone will wind up with a different personalty traits and/or knowledge (say, one dog can sit on command, while the cloned one won't know that if not taught.)

5rm40w | Considering the origins of the English language (of which I have limited knowledge). Could an alien civilisation develop a strikingly similar language? | Well, you have rather easy window into this:
Try comparing languages from other places around the Earth. Do they resemble each other?
Turns out, even if you have people who repeatedly talked to each other, shared environment, and their language was born from the same original language, the languages within just the span of hundreds of years diverge greatly.
Languages sharing roots basically means that the language you speak and language they speak were originally the same language, but both developed in other direction. For example, English is a Germanic language. A long time ago speakers of that Germanic language started living in various places in Europe, and that Germanic language then developed, due to various circumstances, into English, German, Swedish, Norse, etc. Germanic languages belong to wider group of Indo-European languages, which also contains Latin and other Romance languages, like Spanish. Originally these were a single tongue that was just split.
But there are other language families. Within Europe, Finno-Ugric language group is entirely unrelated to Indo-European languages. Japanese belongs seemingly to the language family of its own, it doesn't seem to share similarities with any other major languages. Africa has languages that for example utilize that clicking sound you can do with your tongue, resulting in massively different kind of language. Etc etc.
Basically, even if you have humans, living on the same continent, that couple hundred or thousand years ago were speaking the same tongue, the language they speak today doesn't necessarily resemble much at all each other.
Even further, if you're curious about English, you know how Shakespeare has his curious style of writing? That style is kinda what defines "Early Modern English". But turns out, English just couple hundred years earlier was almost unintelligible to modern speaker,
Here for example is a Bible passage, in English, from 1380's:
> And it was don aftirward, and Jhesu made iorney by citees and castelis, prechinge and euangelysinge þe rewme of God, and twelue wiþ him; and summe wymmen þat weren heelid of wickide spiritis and syknessis, Marie, þat is clepid Mawdeleyn, of whom seuene deuelis wenten out, and Jone, þe wyf of Chuse, procuratour of Eroude, and Susanne, and manye oþere, whiche mynystriden to him of her riches.\
Here's Lord's Prayer in Old English, from about 1000 years ago:
> Fæder ūre þū þe eart on heofonum,
> Sī þīn nama ġehālgod.
> Tōbecume þīn rīċe,
> ġewurþe þīn willa, on eorðan swā swā on heofonum.

5r7gcz | what are the differences between parliamentary systems and the powers of a prime minister versus a president? | The exact details vary from country to country, but basically the Prime Minister (or Chancellor, or similar term in other countries) is the head of *government*, while the President (or, in the case of countries like the UK, which are constitutional monarchies, the Monarch) is head of *state*. The US President combines both roles, but -- if things work the way they're designed to work -- his powers are limited by Congress as part of the system of "checks and balances", which also involve the courts in the three branches of government and the separation of powers.
Usually, the PM is the leader of the largest party represented in Parliament -- so one of the elected representatives. He also chairs the Cabinet, which is also usually composed of elected representatives. From an American perspective, this means that much of the Executive branch overlaps with the Legislative branch.
The PM chairs the Cabinet, which implements laws and also formulates official government policy, so the Prime Minister pretty much sets the agenda. However, most things the PM and Cabinet do is subject to debates and votes in Parliament, which includes the opposition.
The role of a President is often ceremonial; and in a modern constitutional monarchy, the role of the monarch is also ceremonial. The British monarch, for example, has pretty much no say at all in the political system. In theory, the British Queen could refuse to sign an Act of Parliament into law; in practice, this would provoke a constitutional crisis and probably spell the end of the British monarchy. She does, though, represent Britain internationally, and holds some important posts, such as Head of the Commonwealth of Nations, which is a very useful platform for about 50 countries to discuss issues of mutual interest.
In a republic, the President might have a few actual powers. This might be emergency powers, such taking charge temporarily if the government collapses. The German President, for example, reviews all legislation he is asked to sign, and can refer it back to Parliament if he believes the proper procedure was not followed, or to the Constitutional Court if he believes it is not compatible with the constitution. The French President has more wide-reaching powers, and is allowed to actually direct government policy if (and only if) the majority of the Assembly sides with him. | f47a0d0e-e4d1-43c4-896c-b2bcca84c3cf |
5wmzne | Why does inbreeding cause the offspring to have a significantly lower IQ than average? What is the science behind it? | take it that a human body has 2 sets of genes.
When a baby is made, half the genes are from the mother and other half is from the father.
These genes make proteins which help our body work. However, there are occasionally some errors in the genes which ends up making defective/too much/too little proteins which give rise to diseases.
Some of these diseases require 2 faulty set of genes in order to manifest. So if daddy has a defective gene but mommy contributes a normal set, the disease does not manifest clinically (or is milder).
If there are many generations of inbreeding, the set of defective genes are kept within the same family tree; there is no new genetic input from a different family and thus the probability of having a child with 2 sets of defective genes increase. This increases the risk of diseases, out of which some may feature a lower IQ/brain malformations. | 6c42d101-4e24-4639-aaee-9634dbeebcbc |

3efakb | Why can't modern houses be economically independent with solar + battery+ a little backup generator just incase? | A) You need a large array of solar powers to provide full coverage to the home (large initial cost, requires a lot of surface area, potentially takes away from the visual appeal of the home)
B) until very recently, there hasn't really been any cost-effective battery solution for homes (Tesla Powerwall is helping to change this)
C) Most people who live in developed countries don't have to worry about power outages because they are extremely rare.
In these countries, it doesn't make sense to install solar panels just as an emergency backup... you would only do the install if your intention was to go off-grid so you don't have to pay a monthly electric utility bill (and/or because you can sell excess electricity back to the grid / power company to potentially earn money). | c6dded69-ede2-4645-8c64-36863b316e85 |

2jnwq8 | After the Big Bang, how did the Universe form multiple galaxies and establish order from disorder? | Simply put, gravity. And distubances in the uniformity of the universe, which caused there to be larger clumps than in other places.
The universe, at the very beginning, was all energy. But then the universe cooled as it expanded (much like an expansion valve in an airconditioning system makes happen.)
This cooling caused matter condensation on the order of quarks, leptons, bosons, that sort of thing... and their anti-matter counterparts.
These annihilated each other. For matter/anti-matter touching does that. Instant energy. Nothing left behind.
But for whatever reason the anti-matter did not outnumber the matter condensate, and so that's the universe we have today, a matter one.(To an outside observer, it might be the 'anti-matter' universe, for we simply label what we see from our perspective. But that's another discussion.)
Anyway, that caused ripples and disparate distribution in the smoothness of the matter, and because matter has gravity and also an electromagnetic charge to it, this 'clumpiness' caused denser places than others.
These denser clumps of what later condensated into Hydrogen (H) became big enough to let there be light, as many large and in charge stars came to be born. These stars were also in bigger clumps, and so they became galaxies. Probably, possibly, just irregular globular cluster types rather than any spiral or such, at first.
Then the stars, so heavy, so fast burning and blue, blew the hell up and spewed enriched guts (one of my favorite DeGrasse Tysonisims) and energy shockwaves all over the place, causing further disturbances in the smoothness of the universe.
These then shoved other clouds of matter, hydrogen laden, to be disturbed, form more stars, repeating the process. Eventually, these clouds of matter also came to have the other elements like silicon, gold, etc, that would allow rocky planets to form about these stars, all due to the over and over cycle of stars blowing up and making more of the heavier elements past Iron (Fe).
And further, it caused more clumping of matter, and that into stars, but those stars were already centered around themselves and their clouds, so galaxies. And then galaxies ate/merged with other galaxies. And so on.
But it all, ALL can be traced back to gravity, energy, electromagnetics, and the lumpiness in the distribution of the matter of the universe. The chaos that begats some semblance of order.
Speaking of which, I don't find the universe to be very orderly, to be honest. It's about as chaotic as you can get, my opinion. | ff5a3cf2-b0ae-403e-a492-1c840bb0b685 |
j2xnd | can you explain the NFL lockout to me (what it is, why it happened, outcomes of it etc.) LI5 | Ok, im not a big expert but for some reason I'm not seeing most Reddit users as being highly into sports. So basically, just like with every other corporation we have owners (own the team), workers (players), investors (other corporations), and consumer (us). I will break it down as best I can that way. Like all businesses the owners make contracts with the workers. The owners also have a contract that goes over all these small contracts. This contract designates the big things, (percentage of profits, advertising, how long a season is.
**Owners**- (Again, not certain on % but I am quite close). Before the end of the last big contract owners made about 46-48% of total money from the NFL while players made 54-52. The owners did not like this. They are the bosses. This is their investment. So for this negotiation they said they want a higher percentage. Also, each year we have a 16 game season with 4 preseason games. Another concession is that the owners wanted a 2 game preseason and an 18 game season.
**Workers**- The players. Obviously like that they make over half. I mean come on, they are the talent. Without the talent, you have no team to keep making you (owner) money. So they aren't to happy that the owners want more. I believe they weren't for or against the season increase.
**Investors**- These are corporations like Pepsi, or Coke, trying to buy advertising for their company. They want owners to have more money because then the owners might charge less for advertising rights at their stadiums (long shot, not gonna happen). Now the 18 game season, that is what they are interested in. They want this increase. 2 more real games is gold to them. More advertising= more business=more money. Also, corps with deals, such as Pepsi, who sell only their pop during games, make more money. A longer season means more money must be spent to keep their business longer.
**Consumer**- This is really based on your feelings of football. If you really like it, a longer season is good. Now the profit % could affect us. We attend games. If the owners lose money, they are going to charge more for pretty much everything to make up for it. This is bad. Our only concession here is that if they lose money but get a longer season we might not see a big increase as 2 more regular games means 2 more games with a full set of seats, selling merchandise, food, etc.

1iiucm | Can someone explain what quantum suicide and quantum immortality are? | One cat goes into a box, this cat is [Schrödinger's cat](_URL_1_).
To make a long story short....
> He proposed a scenario with a cat in a sealed box, wherein the cat's life or death depended on the state of a subatomic particle. According to Schrödinger, the Copenhagen interpretation implies that the cat remains both alive and dead (to the universe outside the box) until the box is opened.
The reason "the cat's life or death depended on the state of a subatomic particle," is because of the [Copenhagen interpretation](_URL_0_) of Quantum Mechanics. Frankly, I can't explain this like you're a 5 year old. It's hard, mathy shit. But a non-explanation is...
> It holds that quantum mechanics does not yield a description of an objective reality but deals only with probabilities... According to the interpretation, the act of measurement causes the set of probabilities to immediately and randomly assume only one of the possible values.
So, how are these related? The cat in the box only dies when the state of the subatomic particle is known to you. Until then, it's both alive and dead.
Why is this important? Because another theory says every possible outcome happens in one universe or another. This means every time you open the box, the universe "splits." In one universe, the cat dies. In another, the cat lives.
So if you repeat the experiment a billion times, in *one* universe, you've got an immortal cat. Perhaps that cat's consciousness is, in itself, immortal in its own universe. I mean, living a billion times seems pretty unlikely, right? That's more of a philosophical position than scientific one, though. | eda63ec9-f3d0-4fd2-85e5-4a104d141225 |
