Venn x Euler Diagram, what is the difference? | One of them is pronounced just as you expect it to beWikipedia has a pretty good explanation here. _URL_0_ In sum, a Venn Diagram has circles that partially, but never entirely, overlap, but an Euler Diagram can have a circle that is entirely contained in another. If I want to draw an Euler Diagram for the statement "A... |
how do auto-dimming rearview mirrors work? | It depends on what you mean by "effective". The manual tip up mirror uses a wedge prism to either reflect almost all of the light or just a fraction from a lightly silvered front surface. This system is totally optics, and has infinite resolution. It's hard to beat simple physics, but it's not automatic. The auto-dimmi... |
Why isn't it possible for a counterfeit bill to perfectly emulate a real bill? | It is possible. If you had access to every piece of equipment that the government uses to produce currency, you can make the exact same currency. They do make it extremely hard to get certain materials and certain machinery that makes this hardBecause [President Lincoln never wore a turtleneck sweater!]It *is* possible... |
Why are benzodiazepines (chill pills) so bad for you, but work so well? | Benzos really aren't that bad for you, except for the addiction risk. They're particularly safe when compared to what used to be prescribed beforehand, usually barbiturates. You actually have to go well out of your way to manage to OD on benzos. Anyway, as far as benzodiazepines go, Ativan is pretty weak sauce, so if y... |
Why was torture used in the past? | If you are asking from a moral standpoint, this was never a factor to the people looking for information, or to do experiments. Physical torture, or the threat of physical torture could coax info from somebody much the same as psychological could. And for experiments, definitely a controversial topic, but it has gotten... |
How does closing our eyes signal to the brain that it's time to shut down (sleep)? | It's not necessarily so that closing your eyes makes you sleepy. Often it's the other way around: you feel and urge to close your eyes when you are tired and sleepy.

Why are Russians considered "Eastern European," when they're technically North Asians (geographically). | The western boundary of Asia, in this area, is the Ural Mountains. Most of the major cities in Russia are west of that, and therefore are part of Europe.Many people in Russia are not ethnic Russians, but that doesn't change the fact that ethnic Russians are Europeans. The Rus' people were Scandinavian and they moved ea... |
What's the psychology behind serial rape? Do serial rapists genuinely think they won't get caught? | Not an expert, but I'm going to guess that getting away with it once leads to the belief that he will continue to get away with it. I knew a guy who was running some type of credit scam through his employer . It began as 100 or 200 dollars. When there were no consequences, it was easy to do again and again and again. W... |
In the Jared Fogle case, the charges always emphasize that he "crossed state lines" to commit certain crimes. Why does this matter so much? | The fact that he crossed state lines makes this a federal case, rather than a state case. Federal courts have a few different rules and punishments and such, and a lot of resources for the investigation. From a legal standpoint, it's a pretty big difference, since he'll be in a whole different court and prison system. |
What is the "Deep State" in the U.S.? | Deep State refers to the people and organizations that *actually* control the politicians that control the government.

What does the Kantian phrase 'end in itself' mean? | That's not just a Kantian phrase, but it means exactly what it says. End in this context means purpose or cause.

Why is the alphabet in the order it is, theoretically, does it have to be in this order, and why cant it be in just any order? | There is no reason for it to be in the order it is. There is even less reason to change its order.There is no real reason for the order. The order it's in is derived from the order the latin alphabet was in, which is derived from the order the greek alphabet was in, which was derived from the order the phoenician alpha... |
Why does sound seem "louder" during the night as opposed to during the day? | A few things - how much ambient sound is there at night? There are probably fewer cars and fewer people out, so with less background noise, the TV sounds louder because it doesn't need to compete anymore.

Does 'closing your eyes' when fatally wounded have any impact if you die or not? | It's not more of a staying conscious at the time of your death, it's literally stay with me, don't give up, please show me you can still make it.

Why does it seem that the common cold 500 years ago is much more lethal than a cold in the modern era? | You can't really ignore those two things. Those two things are very important for modern medicine. But *other* than those things: our diets are much better, so we have a lot more energy to fight off colds. Food is readily available, so if for some reason we're too sick to work it *probably* doesn't mean you'll starve t... |
Why are the names of oil companies that spill oil into the ocean plastered on the news, but not the party responsible for the California natural gas leak? | The sad truth is that the BP Oil spill got mass attention because it's a much more tangible event and it harmed animals. The California gas leak is equally or worse than the oil spill but I suppose that news isn't selling. I won't say there's conspiracies but some could easily say that parent companies of, say, CNN don... |
Why can't people in the US sue individual police officers like we can doctors? | The state asserts "sovereign immunity". In other words, you can't sue the King unless the King agrees to let you.

Exceptions to sovereign immunity have been carved out of... |
How can a 600W PSU supply 50 A on 12V, while the electrical wires in the wall would literally burst into flames at 50A? | A power supply pretty much conserves power, give or take a few losses. So the output power is 12 x 50 = 600W, as advertised. The input, from the wall, is at 120V So the input current is 600/120 = 5A, well within the capacity of a standard 15A domestic circuit. Incidentally, the wires would not burst into flame at 50A, ... |
Why do spots stop hurting after we remove the puss from them? | For those of use who might not be aware, 'spots' is a term that aussies and brits use for pimples.I assume it is a pressure release.

When and why did basketball hoops become such a staple for American driveways? | Basketball is the second most popular sport in the US.

Why isn't Robert E. Lee viewed as a traitor? | He probably gets let off the hook for being reluctant to go to war and rejection of his military life after the war.

Stereotypically speaking, why do men play baseball and women play softball? | It's not a stereotype, it's a fact. When kids are young, often girls will play baseball.

The sports are very different. Baseball... |
How are sex change operations done? | There are graphic videos on youtube if you're really brave.Both male and female genitals start off as the same set of organs, as you grow in the womb, these organs are acted on by your genetics to become either the penis/testes or clitoris/ovaries etc. The structures being somewhat similar lets some be "recycled" durin... |
when the moon comes up, it's gravity is strong enough to rise the tide. How come small particles don't go flying as well? | Probably the biggest thing to understand is that the moon's gravity doesn't create the tides "all in one go". As the Earth rotates, the pull of the moon has a constant very small effect that over time builds up a sort of standing-wave front that we call the tides. It's the cumulative effect that causes the tides, not t... |
why are Mozilla Firefox and Google Chrome so much better than Internet Explorer? What are the big problems with Explorer? If I have good anti virus software is there really a difference? | Historically you would be correct about IE being a bad browser.

why prosthetic limbs cost almost twice as much as a car | Supply and demand. Money doesn't really have any "real" value, all the prices you see are imaginary, so to speak.

Why can't you fight dementia by training your brain? | You can, to an extent - it has been shown that bilingual people and people who keep their brain active can fight off the *effects* of dementia for longer.

What makes an MR layout car more likely to oversteer? | Think less about the weight transfer, and more about where the weight is in relation to the tires. On rear-engined cars the engine weight is out past the rear tires, and so when the cornering car decelerates, the side force of the engine weight is applied to the rear tires alone, which increases their slip angle, too W... |
Why Are AMEX cards not allowed to be used as much as Visa and Mastercard? | Well I have a business and the fee isn't really the problem if I'm being honest; business owners will say it's the fees but it's bullshit. That extra percent isn't going to kill most businesses. The real reason? Chargebacks. AMEX will process them for virtually any reason. You bought a laptop from me and thought the bl... |
why we sell gas by the volume but not mass, unlike in avionics and auto racing? | Planes and race cars care about how much weight they're moving around as it has a significant impact on performance. A plane needs more power to get more weight off the ground so extra mass is a problem for it if you happen to fuel it on a cold day Passenger cars don't care as much about added mass, and people know the... |
How and why do things get preserved in amber? | Amber is basically tree sap. Bug or animals chilling out near tress have some of it fall on them or they step in it and get stuck.

More rain, more water, so the group had t... |
Why is it that if theres a parking spot with snow, its a lot easier for cars to go in than to go out? Shouldnt it be the same? | You have inertia going in. Plus, the wheels compress the snow as they go over it. It often turns to ice when this happens, forming a ridge of ice the car has to bump over to get going again. Ice has almost zero friction so you can be stuck with each wheel in a little cup barely 1/2 inch or 1 cm deep. Hence the commerci... |
Is my green the same as your green? | Everyone is going to say nobody knows, which is true. But just to break it down a bit You really need to define "see."

Strictly speak... |
If everyone knows California is due for "the big one" earthquake along the San Andreas fault. Why do people seem to not care? | Because in California, nobody gives a fuck about shit', "Los Angeles resident here.

Are paper toilet seat covers (aka ass gaskets) really more sanitary than naked seats or just another example of humans being wasteful? | Chances are, there's nothing particularly hazardous on the seat itself regardless.

why do pictures taken with very good cameras show so much detail that we can't see on our own. | Imagine you have a grid that is 10 boxes high, and 10 boxes wide. In total there are 100 boxes.

Why are some defenses not allowed in court? | When someone says "That's not a legal defense" they're not saying it's not allowed, they're saying that the defense won't absolve you under the law.

Why can't we clone endangered species to rejuvenate their population? | As /u/FixBayonetsLads said, it wouldn't produce diversity.

Dolly was the first mammal cloned from an adult cell, however, her telomeres where much shorter that normal, causing her ... |
How does Impulse = deltaP if Pf = Pi | The bullet changes momentum, as does the block.
