Once you realize you're in a dream, you usually have control over whatever happens. There are different levels of a lucid dream depending on how deep asleep you are. No one is quite sure as to how we reach this type of dreaming, but a lot of people think they need to be completely relaxed and have some sort of meditation just before they fall asleep. Many people experience them without even trying. Nothing will happen to you so don't be scared if it happens. However, in my experience, it may be more difficult to wake up from the dream, especially if it turns into a nightmare. Enjoy the dream but be prepared for anything." ] }

In order to get into orbit, you have to go really really fast so the arc of your fall goes beyond the Earth's curve. When getting into orbit, the majority of this acceleration happens once you're outside the atmosphere. \n\nWhen re-entering the atmosphere, there is no way to decelerate first. Carrying extra fuel to do so would be too cost prohibitive. It's much better to just use the drag from atmosphere to slow down instead, and using heat shielding to protect the vehicle.", "A space ship has to be traveling at really insanely fast speeds in order to achieve and maintain orbit. As the ship ascends, there is less air to provide resistance. This means it can accelerate with less drag. In space there is no air at all, so there is nothing to prevent it from achieving crazy fast speeds.\n\nWhen it is time to return to Earth, there is a problem. As it drops back into the atmosphere, it encounters more and more air. The ship is moving so fast that the air can’t get out of the way. It compresses and heats up. \n\nThe crucial point is this: On the way up, the ship was moving slowly in the atmosphere and then got faster as the atmosphere thinned. On the way down, the ship is moving extremely fast and it must slow down as it pushes its way back into the atmosphere.\n\nThe air actually creates enough drag that it slows the space ship down. This is dangerous, but it’s actually a good thing. The only other way to slow the ship would be to use retrograde thrust, which means it would require twice as much fuel and would be too big to get off the ground.", "Re-entry is by itself not very dangerous.\n\nThere is always the point where you hit the ground after falling through the atmosphere but that is a different problem.\n\nOne thing that makes reentry of spacecraft problematic is speed.\n\nBeing in orbit means that you are going very fast compared to the ground. The ISS orbits at what would be 22 time the speed of sound at ground level.\n\nWhen you are going up into orbit most of the work is not getting up there but getting fast enough. Speeding up to insane speeds is what those powerful rockets are used for.\n\nThose rockets burn a lot of fuel to get that fast, and they would need to carry much, much more fuel if they wanted to slow down again when going down.\n\nTo simplify matter spacecraft usually slow down by letting the friction of the atmosphere slow them down.\n\nThis is where re-entry gets tricks. You go very fast and the vacuum around you gets thicker and thicker and the friction with the little air that is around heats you up more and more and it crates all sorts of issues with heat and shaking and mechanical stress.\n\nThe trick is to slow down gradual enough not to be torn apart by the thicker and thicker atmosphere as you drop down.\n\nOn the way up rockets wait until they are out of the worst of the the atmosphere before they start speeding up for real, so there isn't really as much of an issue. You wait with the speed until there isn't much atmosphere to slow you down.\n\nOn the way down you want to be slowed down so you go much faster inside the atmosphere than you were going when you went up.\n\nIf you could magically slow down your spacecraft before re-entry it would all be much less risky and you could just drop down to earth like Baumgartner did in his Red Bull jump." ] }

Let's take a look at what happens normally (if I had made two withdrawals consecutively instead of simultaneously) and what happens when concurrency happens.\n\nNormally:\n\n1: ATM queries my account, and sees I have 3000 dollars\n\n2: ATM sees I make withdrawal of 300, subtracts 300 from my total\n\n3: It stores my new value as 2700\n\n4: ATM queries my account again, and sees I want to withdraw another 300\n\n5: It subtracts another 300\n\n6: It now stores my account as 2400 dollars\n\n\nWith concurrency, now two ATM's are simultaneously accessing my banking information.

The high level answer (that works for both hardware and software, because I don't know what you're talking about) is the resources need to be managed so only one thread accesses each resource at a time (unless it's capable of concurrent access, for example a synchronized resource). If this isn't done you're frequently get errors. The right fix is to properly manage resources. The work around is to disable all types of concurrency, like threads, to guarantee that two threads can't attempt to use the same resource at the same time." ] }

This brings limitations with it, i.e. you can only represent 256 numbers using 8 bits (2^8 ), so 8-bit games would be limited to 256 colors, 256 levels (think of the Pac-Man or Donkey Kong [kill screens](_URL_0_)), etc.\n\nUsually 8-bit games use 8-bit values for almost everything. I'm not sure how they're able to work with larger numbers, but for example most in-game values have a maximum limit of 255 (on the Pokemon GameBoy games for example, leveling a pokemon past 255 would have it roll over to 0).\n\nSimilarly a 16-bit game can operate on 16 bits per clock cycle. With 16 bits you can have 65,535 values. This means more colors and more levels and increased processing power for more special effects.\n\nNinja edit: 8-bit games generally would have access to 256 colors, but it doesn't necessarily mean the video driver would support it. Old video cards can only have 16 unique colors, but some would allow those 16 colors to be changed by software so you could use any of the 256 possible colors, but only have 16 colors on-screen at one time.\n\nEdit: 8-bits is 2^8 and not 8^2 , got my numbers backwards. :]", "For the most part, it's just marketing hype.\n\nEarly gaming systems used 8-bit processors. The next generation had a lot of improvements : better graphics, sound, faster processors, more memory, better controllers, cartridges that could hold bigger games and 16-bit processors. Some of these things were related to being a 16-bit system, some were just part of being newer/faster. The thing is, emphasizing \"16 bits\", even when people don't know what it means, is a really easy way to say \"it's better\".\n\nThey tried to carry on the hype to later generations but, once you hit 32 bits, simply giving the machine \"more bits\" didn't really make *everything else* better. The Playstation was a 32-bit machine, just as the next generation Xbox like the *previous* generation's N64. People started making things up, like when they said that the PS2 was a \"128-bit\" machine, even though it was mostly 64-bit, there was a small 128-bit segment.\n\nThese days, nobody really talks about how many \"bits\" a machine is capable of. Technically, it never really mattered - it was just an easy number to talk about, even though it never meant anything. Marketing people like to do that - they want to make you think the new shiny thing is somehow better so you go buy one, but they don't want to have actually *commit* to anything that could be argued against.", "\"Bits\" refers to the width of a \"data bus\" in a circuit, and like how pipes in your plumbing carry water, circuits carry data - numbers that represent every detail of the game at any given moment, including details that you never even get to see. Marketers use the highest number of bits of all the important components in a console to advertise it. Usually the component they use is the central processor. More \"bits\" can make the game console go faster. Imagine it's like replacing pipes in your plumbing with wider pipes, so more water can flow through - in the game, it means more data, and therefore more robots, more princesses, more polygons, more animation, and higher frame rates.", "Computers count in binary. I won't ELI5 the binary number system for you, but basically 8-bits mean you can have 8 zeroes or ones (example: a number like 10001110). The maximum number is 11111111 which corresponds to 255 in our everyday counting system (called base 10). So, an 8-bit computer can only count up to 11111111, or 255.\n\nA 16-bit computer can count up to twice as many digits. They can have 16 zeroes or ones. That means the max a 16-bit computer can count to is 1111111111111111 or 65,535.\n\n16-bit computers, while they can count a lot higher (and thus keep track of more data at once) are more complex and the technology wasn't cheap back in the days of the NES. Eventually, we progressed to 32-bit computers controlling modern consoles. Desktop PCs have advanced one further to 64-bit because the amount of RAM they use requires a computer to count higher than 4,294,967,296 (the highest a 32-bit computer can count to).\n\nThe amount of bits in a computer is loosely related to the power, but since about 1990 this hasn't been the case at all. Bits have increased as processing power increased as a matter of necessity. Bits increasing don't cause the processing power to increase. Intel or AMD (they manufacture processors) could create a 256-bit chip that is no more powerful than the processor in the NES if they really wanted to." ] }

This is where they get a lot of their funding. The BBC also has a commercial branch which sells the rights of the TV programs they make to other TV broadcasters overseas so they can be shown in those countries. That would be how most of their shows are shown internationally I presume (without having checked or knowing too much about it) I'm sure there will be someone else who can explain it better but this is the essence of it I believe.", "Anybody who watches broadcast television (or \"almost as-broadcast\", e.g. internet via streaming) in the UK has to pay for a television licence (currently £145.50 -- about US $220 -- per year). This applies *regardless of which TV stations they choose to watch*, so even if you never consume anything produced by the BBC you're still required to pay if you own a television. However, approximately 92% of the British public use *some* BBC services each month (that might be TV, radio, and/or online).\n\nThe total of all those TV licences comes to about £3.4 billion per year (around US $5 billion), and out of that the BBC funds for UK consumption 8 national television stations (and one regional one), 11 national radio stations (and nearly 30 regional ones), and one of the largest and most respected websites in the world. In return for the British public paying for the BBC in such a way, it is illegal for the BBC to carry advertisements on its domestic output, or to charge the British public in any other way for live TV/radio (although it *can* charge for DVD boxsets etc).\n\nOutside of the UK these rules don't apply -- what's more the British public would feel somewhat upset if their money (which they have no choice but to pay) was being used to provide subsidised or free television to people in other countries. So the BBC also owns a for-profit company which sells BBC content (both entire programmes and intellectual property rights, e.g. for remakes) to other countries around the world. This company, BBC Worldwide Ltd, has global revenues of around £1.2 billion a year (about US $1.8 billion).\n\nSo to (finally!) answer your question, the BBC in total has around £4.6 billion income per year, equivalent to nearly US $7 billion. It's restricted in that some of that money *must* be spent in the UK, and some of it *must not*, but as you can imagine a media company with that sort of income is more than capable of supporting a \"massive international presence\".", "If BBC were smart, they'd offer to sell BBC programming (including iPlayer) internationally for .... $220!" ] }

Now, it's not surprising that, for example, your ability to learn French vocabulary correlates with your ability to learn Spanish vocabulary, or that if you know a lot about physics you're likely to also know a lot about chemistry. But it turns out that *everything* related to mental aptitude - memory, mathematical ability, artistic creativity, formal logic, vocabulary - correlates. This doesn't mean that one person who's a brilliant mathematician is going to be a great poet. But it does mean that if you choose a thousand people at random, the ones who are good at one will tend to be good at the other.\n\nThe most plausible reason for this correlation is that there is a single underlying factor, which we call *g* or general intelligence, that is responsible for all or most of this correlation. Using a type of math called principal factor analysis, we can identify *g*, which we measure with IQ. By convention, we represent IQ as a normal distribution (a bell curve), with a mean of 100 and a standard deviation of 15. 68% of people have an IQ within one standard deviation of the mean (from 85 to 115), 95% are within two (70 to 130) and 99.7% are within three (55 to 145). \n\nWhile it might seem like *g* is just a mathematical artifact, it has major implications in the real world. *G* is one the best, or the best, predictor for things like how well you'll do in school, how well you'll perform in your job, and how likely you are to stay out of jail. And the predictive power of *g* remains even when we control for the effect of things like how rich and well-educated your parents were. \n\nIQ's not perfect, of course. While it explains a lot about how successful people are, it doesn't explain everything - things like how hard you work, how good your social skills are, and plain dumb luck are also very important. Some psychologists think there's a hierarchy of factors of intelligence, with both a single general factor *g* and many sub-intelligences in more specific fields like artistic ability or spatial reasoning. ", "IQ tests were **originally** developed to assess mental retardation in French schools. They would give the test to schoolchildren, and use the test to determine which children were \"behind\" their peers. For example if a student was 11 years old but was scoring on the level of a 6 year old, that child was determined to be \"retarded\" and was put into a remedial class.\n\nIQ tests were then adopted by the US (specifically by Stanford University), and their purpose was expanded. [That's where you get the classic \"Stanford-Binet\" IQ test.](_URL_2_)\n\nIQ works by testing everyone and comparing everyone to everyone else. \n\nThat means that if you are smarter than 50% of people, and dumber than 50% of people, you will have an IQ of 100. If you are smarter than 75% of people, and dumber than the other 25%, then you will have an IQ of about 110. The tests are re-written and re-calculated to make this statistically true.\n\n[Look at this statistical \"bell\" curve.](_URL_1_) This is the IQ curve. 68% of all people have an IQ between 85 and 115. 95% of people have an IQ between 70 and 130.\n\n2.5% of people have an IQ lower than 70. These people range from mildly mentally challenged to **severely** mentally disabled. \n\n2.5% of people have an IQ of over 130. These people are smart. They are very good at the things you do on IQ tests (math, vocabulary, grammar, spatial logic, etc.)\n\nBut smart is a fuzzy term. Is a great musician smart? A great musician might suck at math and be dyslexic but create complicated and moving compositions. Likewise a great mathematician might have horrible grammar. A great writer may suck at trigonometry. \n\n\"Smart\" is relative, and IQ tests only measure a few specific things. \n\n1. If you are completely incapable of doing the things on an IQ test, you are probably mentally handicapped (the entire original purpose of the test was to identify and help those people).\n\n2. If you are really, really good at the tasks on the test, that **doesn't necessarily** mean you are a genius, it just means you are very good at the tasks on the test. It takes more than that to be a genius.\n\n[Further reading.](_URL_0_)" ] }

Colonists would likely make up their own holidays \"First Human on Mars Day\" (aka /u/faisent day) and those might be tied to a Martian year but they'd still use Earth years in their day to day operations.\n\nOnce the colony became more and more self-sufficient things would slowly diverge from an Earth-centric Calendar. *The Grand /u/bfr0g1 Memorial Greenhouse* would still need to draw sunlight during the Martian day; its workers would start to organize their shifts around this cycle. As they form a large portion of the colonists, the rest of the colony starts to follow suit; at first it is a crazy hodge-podge of conflicting time-zones; some of the colonists follow Martian Standard Time, and others stick with Greenwich Mean Time. The few independent businesses finally decide to switch to MST as most of their customers are using it, leaving GMT a standard only to officers, communication specialists, and the few cross-system pilots that have to deal with Earth on a semi-regular basis. \"Months\" are kept simply because seasonal changes aren't as dramatic in enclosed spaces; though the Martian December (which occurs twice in a Martian year) is only used to track Christmas for the few Martians that keep up with that religion. Already \"/u/faisent Day\" is the holiday most Martians feel attached to, followed closely by \"/u/bfr0g1 Day\" - when Mars officially became self-sufficient for its food intake. /u/faisent day Martians exchange gifts, similar to Earth's \"Christmas\" and on /u/bfr0g1 Day kids hunt for variously colored root vegetables and adults dress in garish clothes to represent their independence from Earth.\n\nEventually the Mars colony decides that Earth isn't really needed, even for resupply and luxury goods. They examine their long history and decide to move completely away from the standard Earth calendars. They decide to start their Calendar on IFE or Independence From Earth day. 200 million Martians rejoice in their new-found Independence, and (since this is fantasy and fiction) the various Earth nations applaud and rejoice that humanity has a new home where it can prosper." ] }

Bolt-action tend to be easier to maintain and more reliable. But I hesitated to put that point because that's not always the case. You can make a good or simple enough design that it's not an issue. It was usually an exemption that confirm the rule, but it apply to more and more modern so that reliabily less and less true.\n\nBasically bolt-action trade firing speed for precision, which suit long distance shooter more. You usually see semi-auto sniper more in a Marksman role.", "The long and short of it is that semi automatics use bullet energy to re-cock and expend the spent casing, they have more moving parts, and this makes it more difficult to have the same tolerances as well as changing consistency from shot to shot. Bolt action is simpler, easier to make with precision, and very consistent. \n\nThe accuracy of a rifle comes down to consistency and precision. \n\nPrecision means that all of the parts fit together with very close tolerances and with a minimum amount of slop or wiggle. The more mechanically complex a rifle is, the harder it is to make each part with precision. It's not impossible to create a semi automatic rifle with accuracy but it is difficult and expensive, and as parts wear it can change. \n\nConsistency means that each time a cartridge is chambered, fired, and ejected, it is done the same way. All rifles must warm up with a few cold shots first but after the initial shot a good rifle will do this predictably. What you don't want is for things to change in an unpredictable way from shot to shot. Part of this is the design of the rifle, how heavy it is, how tight the tolerances, and how it deals with heat. The other part of this is the ammunition, whether the grain count is reliable and each round fires like the other rounds. \n\nBolt action rifles push the range and consistency out to the edge from precision parts, a predictable cold vs hot bore shot, and the bolt mechanism is robust, easy to clean, and simple. You want a minimum amount of factors that can affect the shot so it's more predictable and a simpler mechanism reduces these factors. \n\nSemiautomatic rifles of today can meet or exceed the range of bolt action rifles of yesterday, but they are more finicky and more prone to drift as the different parts wear out, and cleaning is much more important as the gas pressure must re-cock the firing mechanism and expend the spent casing. This takes energy from the bullet and also changes from shot to shot with environment and how clean it is. " ] }

The healthy ways usually have you at a smaller calories deficit and include nutritionally dense foods, little to no refined sugar, little simple carbs, lots of veggies, and a good amount of protein.

The EU, both directly through its member nations, as well as through European and international institutions, such as the ECB (European Central Bank) and other banks, has lent the banks and the government of Greece large amounts of money. Just as your bank is going to want you to (eventually) pay back your obligations as agreed upon, the EU wants Greece to pay back its loans. Greece currently spends more money than it takes in through taxes and fees, which is to say that it is running a deficit. In order to ensure that they get paid back, the EU and other creditors want Greece to take reforms to increase the amount of revenue that the Greek government brings in, and reduce the amount that it pays out. This is called austerity.\n\nWhy is austerity bad, or at least seen as undesirable by some? Well, a tenet of Keynesian economics (this is pretty mainstream) is that austerity is what's known as a fiscal drag. Taxation, on the whole, tends to slow down the nation's economy, absorbing money out of the economic system, while government spending tends to pour money into the system, serving as fiscal stimulus. You might recognize fiscal stimulus as in the fiscal stimulus packages that the US government passed in 2008-2009 during the heart of the Great Recession. In addition, on a more individual micro level, people don't like it when their taxes increase, or when their government benefits (think Social Security, Medicare, etc.) get cut. So, there's political pushback against austerity packages as well.\n\nUltimately, one thing to note about government debt is that it's fundamentally not like personal debt. As long as a nation's economy is growing at a reasonable pace (and tax receipts increase along with the economy), it is entirely possible for a healthy economy to be partially financed by debt. However, if an economy begins to enter recession, those debts become harder and harder to pay off. So, there's a tradeoff between increased government spending, which will provide fiscal stimulus to make the economy grow and the debt load relatively smaller, and decreased government spending, which may lower the debt value in nominal terms, but at a cost to economic growth.", "Imagine you lived at home with your Mom, Dad, Grandparents, brother, and sister. Your Mom has a great job and, as a result, everyone in your house lives a pretty great life.\n\nSuddenly, things don't go too well. Your Mom's job cuts her hours and the amount of money that your parents make no longer covers all the bills. Your house slowly starts to fall apart. The lawn doesn't get mowed, weeds sprout up, and it becomes an eyesore to your neighbors.\n\nIn fact, your house has started to risk the value of your neighbors' houses so they all pitch in and agree to loan your family money so you can get stuff back in shape... paint the house, fix the roof, clean up the yard, etc.\n\nYour parents take the money but, instead of spending on things that help your home stay together for the long-term, they invest it in programs that allow everyone inside your home to live a pretty comfortable life... some would say a luxurious life. \n\nNow we are back to the point where your family has burned through the money. Once again the neighborhood is faced with your crumbling home risking the value of their homes... and because of that, they are willing to entertain the idea of giving your family more money...but they are scared that if they do that, your family will just blow it on more luxury items and stuff that doesn't fix the actual issue of living within your means.\n\nSo your neighbors offer to give you the money and help bail you out of your situation, but only on the condition that you do not spend the money on things that do not directly fix your home's problems. \n\nThe issue is that there are differences in opinions when it comes to what kind of expenses are both luxuries and investments and which are merely luxuries.

A decent analogy is a tangled skein of yarn. It's very difficult to untangle it, but if you take some scissors and cut through it, you can't put it back together. This is because the long polymer chains have been physically cut. The two sides don't generally spontaneously reconnect if you put them next to each other - it might require some outside input of energy (like melting them together).\n\n\n*some plastics do have semi-crystalline structures", "Some things do just stick back together. If you rip a piece of metal in half in the vacuum of space, you expose raw, unoxidized metal on the inside. If you stuck the pieces back together, they would be \"cold welded\" back together. This usually doesn't happen on Earth because exposed metal surfaces quickly become oxidized in the oxygen atmosphere. It would be like trying to stick two buckets of water together, yes they're both water but there's an outer layer that simply isn't water.\n\nAlso a big part of things \"sticking\" together is from air pressure (or lack thereof) and friction. If you shuffle the pages of two phone books together like a deck of cards, they become extremely difficult to pull apart because of the friction between the hundreds of pages. Phone books are essentially shredded up, \"broken\" tree, but you can stick them to each other with friction. Air pressure can stick things together as well, like when you push a suction cup onto a flat surface. The suction cup tries to push itself back away from the surface, lowering the air pressure inside the cup. So the air pressure of Earth's atmosphere outside the cup pushes with more force than the low pressure air inside pushes outward, resulting in a net \"towards surface\" push, which increases friction on the surface, keeping it from sliding around. A suction cup hanging from a ceiling stays there because air pressure overcomes gravity, while a suction cup on a wall stays there because friction overcomes gravity. If you can force two objects together and remove a sufficient amount of air from between them, or intertwine them as with the phone books, they will stick from friction and/or air pressure.\n\nSo when you break a piece of plastic, you leave a deformed, jagged edge. You can't stick them back together because there will always be air between them pushing them apart with the same force of the air trying to push them together. Even cold welding would leave a noticeable border on the metal because the pieces wouldn't line up properly, but the partial surfaces that do touch would be cold welded.", "Mostly the atomic bonds. At the molecular level the crystal lattices (or just bonds) have a certain amount of “potential energy”. At some point, you break the bonds by a stress overload and thus the bonds cannot be stuck together unless through a process of heat treatment. Annealing is a common way, especially to make the material more ductile.", "It's like chains in an atomic level.\n\nYou may exerce a force that will cause some link to open, but pushing them together won't make the link close again. ", "It depends on the material. Most materials are held together by Van der Waals bonds, which you might have learned about in high school chemistry (non-ELI5: dipole interactions, London dispersion forces). These forces are basically caused by the distance between the proton and electron in an atom or molecule creating small electric fields which attract each other. All materials have these attractions holding them together, and they're very strong at small distances. Think of a Jolly Rancher-- it's basically just sugar, but it would be very, very difficult to pull apart.\n\nHowever, these interactions decrease very strongly with distance (non-ELI5: about 1/r^6, compared to gravity or pure electronic interactions which scale about 1/r^2). When you break something and put it back together, you're not going to put it back exactly how it was atom by atom. The mismatch between the surfaces combined with the roughness of the surfaces caused by the break means the two pieces can't come close together again and stick back together. If you could exactly line them up how they were before atom-by-atom, though, they would stick back together as good as new! You can test this with materials like mica, which breaks perfectly smooth, so it's easy to stick it back together.\n\nSome materials have additional forces holding them together. Metals have metallic bonds, a \"sea of electrons\" where the electrons float between atoms. As another commentor mentions, many plastics are made up of long chains that tangle up with each other to keep the material together (though it depends on how long the chains are and how crystalline the material is). However, Van der Waals forces are universal, so you can always count on them holding a material together.\n\nHere's a good series of lecture on the subject of the forces holding surfaces and molecules together, if you're interested: _URL_0_" ] }

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.

A scientific law isn't something that's \"truer\" than a scientific theory. \n\nA law gives a relationship, a theory gives a reason why. Laws are not always true; they are only necessarily valid under the circumstances that the observations that they arose from existed in.\n\nFor example, Newton's Universal Law of Gravity only applies in weak gravitational fields. In strong gravitational fields, general relativity is a more accurate model.", "It's both actually. Laws and theories are actually completely different and one is not necessarily better than the other. A theory is an explanation of some natural occurrence whereas a law is a mathematical statement of how something occurs within defined limitations. Often times, theories will include laws within them. So a theory of gravity might address that the reason two bodies with mass are attracted to each other is that gravity exists and behaves in such and such way or it could go into what gravity is exactly (the mechanics of it etc). Newton's law of universal gravitation on the other hand, is the statement that the force of gravity between two bodies (in non-relativistic scales) is equal to G * m1 * m2 / r^2", "A “law” is a specific statement, usually an equation describing the relationship between two or more measurable quantities. For instance, Newton's law of universal gravitation:\n\nF = G m_*1*_ m_*2*_ / r^2\n\nA “theory” is a broader model of some set of phenomena. For instance, we might speak of the Newtonian theory of gravity. The centerpiece of that theory is that law of gravitation, but the theory as a whole entails other assumptions: for instance, that there is in the first place an attractive force (which we call gravity) between all objects with mass. Basically, if you were trying to explain gravity to someone who had never thought about it before, what you would tell them would be the Newtonian theory of gravity.\n\nAnother example would be the theory of general relativity. At its heart you have a certain physical law generally referred to as the “Einstein field equations”:\n\nR_*μν*_ - ½R g_*μν*_ + Λ g_*μν*_ = (8πG / c^4) T_*μν*_\n\nThe remainder of the theory of general relativity is the explanation of what those letters represent and what any of it has to do with gravity.\n\n“Gravity” is neither a theory or a law. It is just the word we use for a physical phenomenon. We have two standard well-developed theories of gravity: Newtonian gravitation and general relativity.* The former is substantially easier to work with, but we know that it is not perfectly accurate and in some extreme cases it is not sufficiently accurate. The latter is much more complicated, but it seems to work in all testable cases (although there are some questions remaining about some extreme cases that we can't currently test). Each of those theories consists of both laws and other matter." ] }

The only human cells that have this ability to differentiate at large into different tissues, would be stem cells. ", "These are different reproductive strategies. In nature, the more diversity a species has means the more likely they will survive to reproduce.

This is useful because you don't need something to pollinate your flower and you don't need a sexual partner. The downside is that as clones, they are more susceptible to disease. Commercially, growing from bulb is also beneficial because it means you can guarantee to the customer that their tulips are going to be the same colors as what is on the box.\n\nFlowers (and all sex organs) require male and female gametes (sperm and egg) to make offspring. The benefit to this system is that this mixes up the genetic material of mom and dad, producing unique combinations. Think about how in big families some kids look more like one parent versus the other and some siblings look more similar to others, despite coming from the same parents. More genetic variation means more trait diversity, means more chances at least some of the offspring will survive to reproduce." ] }

One of the things he’s most recognized for is that he discovered what’s called Hawking Radiation. \n\nBefore him, black holes seemed like they could only do two things, get bigger by having matter fall into them or stay the same size forever. Then Hawking applied a fun little bit of quantum mechanics to the black hole which implies that black holes can actually, very slowly, radiate energy. This means that black holes aren’t stagnant at all, but can “evaporate.” \n\nAnother quick thing is that he proposed a way of solving the quantum information problem with black holes. For a long time, there has been a problem where it seems like black holes destroy quantum information, which is a huge violation of a lot of fundamental physics. He proposed a solution to this, which I don’t understand nearly well enough to put in simple terms, that involves using something called the holographic principle that allows black holes to behave how we expect but still preserve information. \n\nSixty Symbols on YouTube has a few great videos on Stephen Hawking, which I recommend if you’re interested.

The ratings are about what allowed to *viewed* by people of this or that age, and there are huge regional differences. The legal constraints in your question are about what is allowed to be *filmed*, and, again, there are huge regional differences.\n\nThe films you mention were both filmed in countries that don't freak out over nudity, an aspect that doesn't translate across borders very well. (The US release of Malèna had 17 minutes edited out.) The French film contained nudity, not sex, and nudity isn't considered harmful there. The laws protecting child actors still require parental consent and oversight, but this was a non-issue.\n\n(slight spoilers below)\n\nIn Malèna, in the movie, Renato's scenes with Malèna all take place in his imagination. The one time he has an actual encounter, he imagines the prostitute is Malèna. This abstracts the (in-film) issue quite a bit, removing a lot of the otherwise squicky feeling that would have existed had these encounters actually and knowingly involved Malèna. And making the one real encounter take place with a prostitute in a brothel that his father took him to covered the issues of consent reasonably well. (His spying, and one of the things he saw while spying, was more squicky than the sex scenes... and most of the things the character saw, the actor didn't actually see.)\n\nIn real life, the 14-year-old actor really was nude in that one scene, really did touch two different actresses (just touched with his hands, not doing anything 'sexual' by the standards of most countries), and was really quite embarrassed at the time that his parents (who vetted everything) were present the first time he saw a naked woman (according to the actor at age 16, in interviews when the film was released).\n\nThat \"never saw a naked woman before\" tale sounds like BS, likely concocted for the benefit of his parents.\n\n(\"So, do you just not have internet, or ...?\")" ] }

Not so fun fact(for the trees): When a tree drops its leaves, it loses nutrients. Evergreens typically live in cooler climates- and when its not hot, things don't decay very fast. Which means, the soil is not exactly...tasty. Thats a problem. So, how do they cope? Well, if losing leaves means losing your nutrients, and you can't replace what is lost, you probably want to hang on to those leaves!

Standard of living is also a viewpoint, with the paradigm of our society being that we are doing it right. Tribes isolated in say, the Amazon, may think their standard of living to be great, compared to our viewpoint of the way we live being great. It may be that their \"standard of living\" is not the same as ours, but they could be content with the simple life.\n", "It really depends on how many people you want to live on Earth. Estimates vary, but if everyone lived like an [average American the Earth might sustain ~2 billion people](_URL_0_). If all 7.2 billion of us lived like Americans we would need over 4 Earths to sustain resource extraction and resource use. If we all lived like the Kung! (hunter-gatherers) we could probably support a couple to several more billion people on this planet.\n\n* This is a finite world with finite resources. More people = less resources per person.\n\n* We currently need to share these resources not only with our fellow 7.2 billion people, but with all the other critters in this world. This is really important, because our survival depends on a healthy planet, with functioning ecosystems. There is no point in having 20 billion people, domestic livestock, and not much else.\n\n* Technology, while wonderful, is often a double edged sword. While it can become more efficient, the use of it often increases anyway. For example, everyone thought moving from horse + buggy to cars would be more efficient and clear up traffic. Turns out, people just bought more cars, and traffic still remains a significant problem to this day. When we make our technology better/cheaper more people want it, this eats up more resources and produces more waste than living simple technology free lives (e.g. hunter-gatherers or early agrarian). I am not suggesting that we live like hunter-gatherers, but it is folly to think that technology can \"save\" us when it is our global behaviour and our laissez-faire attitude that is the problem. If we combined alternative, sustainable and truely green technologies (not that [greenwashing](_URL_2_) bullshit) with a complete paradigm shift in the way we view how our economies function then yes I think we could do it. Technology, without behavioural modifications will do nothing.\n\n* Technology is pretty far away from mining or extracting resources off-planet. Mostly because right now it costs a shit-ton of money just to get a kg of stuff into space (~$10,000/kg using the american space shuttles). It is not economically feasible to be shipping metals and other precious material from off-world, and probably won't be for many decades. \n\n* Another way to look at this is we currently don't have a food shortage problem, we have a food distribution problem. We could feed everyone on the planet today, and end starvation but that could lead to unintended consequences whereby we have another population boom and further exacerbate our already stressed out ecosystems. We as a human species really need to think about how we are going to manage our population, and manage our resource use so that it can be sustainable forever.\n\n**Edit:** I should also note that there is no single correct answer and that *superfab12* makes an excellent point in that \"standard of living\" can have different interpretations. We should not equate a high standard of living with a modern lifestyle. A high standard of living IMO means that all basic necessities of life are met (e.g. food, water, shelter, healthcare) and then some. I.E. all of, or most of [Maslow's hierarchy of needs](_URL_1_) beyond the physiological ones are met by the society." ] }
