Unfortunately, while... |
Why do all new video games have the same purchase price? | To prove collusion, you have to establish malicious intent and a conspiracy among the publishers. This is very hard to do, since the most plausible reason is that a bunch of finance majors did research and models and predicted that the $60 pricepoint is best for AAA games. Note that there are quite a few games that do ... |

Why are humans the only species that has to brush their teeth? | I'm not a scientist, but I think it's because we eat foods that are more conducive to plaque growth, and also our teeth may have become weaker through evolution because we don't need to eat tough plants or uncooked meat. |
How can a computer shut itself down and then turn itself on again? | The *system* is indeed shut down. By this I mean the operating system is shut down. The *computer* is still on the whole time.

What would happen if for some reason the earth were to suddenly and instantaneously stop spinning? | Yes, you'd go flying, just like if you're not wearing a seatbelt and slam a car into a wall, but this would lessen the further away from the equator you are. Really close to the poles it wouldn't do anything to you. Not that this would matter because even if it slowly stopped spinning those near the equator would die a... |
If addiction wasn't an issue, would heroine actually be bad for you? | As far as I'm aware pure, medical grade opiates aren't very neurotoxic and aren't damaging to any organs or systems.

Heroin is ... |
As Printer Ink has been overpriced since it was first sold, why are there no cheaper alternatives by now? | There are printers that use cheaper ink, but you probably didn't buy one because it was more more expensive. I don't own a printer myself, but from what I've read on Reddit, it seems that most laser printer owners don't regret it. The toner cartridges cost in the $30-$80 range depending on the printer, but they last fo... |
Is 'Race' a scientifically accurate term to use, given humans have only one species and there are no taxonomic differences amongst them? | white" or "Asian" you have a rough idea of what they look like if you come from the same cultural background as me. But these categories are unscientific and culturally subjectiveRace is a much broader topic than biology. There is no biological delineation of race. There are loose groupings of pheonotype that are loose... |
how could a household LED lightbulb be rated to last 13.9 years if it likely wasn't tested for that long of a period? | First, the components the bulbs use may have longer-term data from being tested and used in other capacities. Each component has a projected life span under the load conditions it will be under in the bulb, thus the bulb's life will dependent on the component with the shortest projected life. They also do bin testing. ... |

Why do passive index funds charge a percentage of assets rather than a flat fee per investor? | > It would stand to reason that for a passive index fund the costs are associated with the number of investors and their buys and sells into and out of the index fund I don't think this is true, and even if it would, think about what would happen. Small investors would be discouraged from using that company, since thei... |
Landfill. Surely it's a really really bad idea to fill holes with a partly rotting, gassy, mix of crap? Won't we run out of places to put it? | According to a Penn and Teller Bullshit I watched a while back A 10 mile square modern landfill could hold a century worth of America's garbage.

How or where do radio stations get their music? | I work at a college radio station. We get a constant stream of new music sent to us by record companies that we digitize.

Beyond that, most student djs just play music off their laptops,... |

How is Tom Brady, The Patriots and the whole Pats organization able to keep the AFC and Superbowl championships if it has been determined they cheated? | I think a big factor is that they cheated in the Afc Championship game, not in the Super Bowl. The colts said it best when they said that it wouldn't have mattered because the pats beat them so bad. If they barely won maybe the penalty would have been different No way to really know. Penalties were this are just subjec... |
Are the giant LED panels on every tough guy's pickup truck just the equivalent of a rack of roof beams, or is it something else? | It's super illegal to run them.

Luckily most people know what it's like being blinded by them to know not to run them on the road. |

How close is the reproduction of classical music (Mozart, Beethoven etc) we hear today is to that of the actual music composed ? | The caliber of certain instruments has changed.

Good Luck! |
How does focus work in cameras? | Largely depends on the camera. For the most part it's all about identifying a sharp, contrasted edge. Older cameras often have a [split prism] focus screen.

So I'm watching Thunderball and Bond whips out an underwater flare, what I'm asking is how the flare works underwater? | Flares have both fuel and an oxidizer in them. The fuel is pretty self explanatory but the oxidizer is a chemical where the molecular structure contains lots of oxygen atoms. When it's heated up the molecule breaks apart and the free oxygen atoms can be used to support a fire. Flares burn brilliantly in the air despite... |
Flossing, why do it if I brush and use mouthwash, any risks? | Dude my dad is a dentist and I didn't start flossing my teeth regularly until Steve-O told me to. _URL_0_ He's not wrong, your breath improves dramatically if you floss regularly.

The psychology behind a mother blaming her child when said child is being molested/raped by the mother's husband. | I also think it is denial that the man they dedicated their life to, could, of his own volition, do something so horrible without being coerced into it. No one wants to believe they share their bed with a monster. Also, some jealousy could come into play. The daughter is younger, there for, prettier and more desirable.... |

The 3gb barrier in 32bit operating systems? | In a computer's RAM each byte has an address. A 32 bit OS only uses 32 bits to store those addresses. Which means the number of bytes of memory you can use is limited to the maximum number you can store in 32 bits which is around ~4 billion, giving a theoretical maximum of 4GB. In practice there are other things mapped... |
ELI5: Why are Andy Warhol's paintings of Cambell's soup so famous? | Short answer: Because art critics are morons. Long answer: Art critics derive money, status, and self worth from being liked and popular. Someone decided that a painting of soup was incredibly amazing. In order to appear trendy, other people decided to adopt this idea. Because there is very little free and critical thi... |
Dimensions: How can there be more than 3 dimensions? | As other people have mentioned, time is often considered the 4th dimension. But there is another way of looking at it.

It's using... |

Wouldn’t the building collapse on top of you? | If a building is close enough to the blast that it gets knocked over, you do not have to worry about it, because anythingthat could destroy a building would have the same result on your body. seeking shelter is done to reduce exposure to radioactive fallout. If you managed to survive the blast, that's your biggest conc... |
How does receipt paper work? | It's [thermal paper]. Thermal paper is coated in a solid mixture of dye and acid. When heated, the mixture melts and the dye reacts with the acid to change to it's coloured state, and then re-solidifies.

The Birthday Paradox and what are the odds that someone was born the same month and day (not year) as me? | The Birthday Paradox isn't that somebody was born on the same day **as you**, it's that when you have a room full of people, the odds that at least **two of them share a birthday** gets very high, very quickly.

Why would we consider it ridiculous to call Obama white, but not to call him black, when he's half black half white? | From a **purely vision-based** look at his actual skin tone, Obama is black by pretty much most people's definition of a 'black person'. To say he's white would be silly, then.How many "pure" black people do you think there are in America? We 've had 200+ years of voluntary or involuntary of black and white interbreedi... |
- why do people pick at scabs, fits, pimples, etc? We know it's bad and it hurts, but we still do it. | I don't have an answer for you but I can tell you that when I spent some time looking after some young baboons they also liked picking off my scabs when they were grooming.Because sometimes it works out. Some pimples really do just go away or at least look less horrid when they pop, and some scabs are ready to come off... |
How Can I Unlock The Front Door To The Apartment Block Where I Live With The Same Key I Use To Unlock My Apartment Door? | I think you are asking why the key to your apartment ALSO unlocks your complex's front door. In short, it's similar to a skeleton key. Every key probably has certain teeth that are identical from key to key. These are the teeth that have to be accurate in order to open the front door. Any other teeth can be inaccuratel... |
Why is the American power grid so bad compared to other western nations? | We get hit by bad weather, unlike the rest of western civ. Our country is much larger and much more spread out - so instead of spending money on where a tight concentration of people live we have to spread that money out to accomodate for that.

How many years of memories can the brain support? | The question should be could you remember things accurately from when you were 20. And that answer is no.

Can someone explain to me what FOREX trading is? And why is it gaining a lot of popularity right now? | FOREX stands for 'Foreign Exchange', or investing in other national currencies. So you 'trade' your 1000 US dollars for 970 Euros.

Why do I look at and think the shirt is Yellow and White but my friends all clearly say it's Dark Blue and Black? | I can tell it's blue and black but there's a yellow wash in the image, possibly due to a filter. The black has a very yelliw tinge. |

Why was America named after Amerigo Vespucci of all people? | Because Columbus didn't *technically* discover America. Yes he was the first European there, but he didn't even realize it.

Not only that, everyone had a good idea of jus... |
how did humans first discover black holes and realize what they were? | The simple explanation is that they were the consequence of the equations physicists use. If you plug in certain numbers to certain equations black holes are predicted. After the prediction we started looking for them and found evidence.

Why is Japan's debt larger than Russia's, china's, and Germany's combined? | The Japanese have been fighting a deflation-driven recession since the early 90s. What that means is that people spend less money, the economy shrinks, and people get laid off.

Why does it take 10 days to unsubscribe me from mailing lists? | Because companies pre-plan email marketing campaigns.

LI5: explain to me how scientists date fossils and come up with dates millions of years ago. | By the way carbon dating doesn't work for things more than 60,000 years old because its half-life is too short and after about 60,000 years the Carbon 14 left isn't enough to measure very accurately. There are other types of radiometric dating that work much the same way but for longer time periods like potassium-argon... |
Why is the constitution given so much importance in the US? | The reason the constitution so cited so frequently is it and the amendments established boundaries for where and what the federal government could/can legislate.

Why do we not see new political parties emerge in USA? | The first-past-the-post system is also not doing third parties any favours. In order to have a single seat in congress, a third party candidate would have to win at least 34% of the vote in one district/state. Some parliaments, especially in Europe, use some form of proportional representation. So if the Green party go... |
Why isn't lead poisoning a more urgent priority? If there's no safe level of exposure, and the effects of lead poisoning are permanent, why isn't it eradicated? | Because it would cost too much vs how much it impacts health.

I have no real interests in Italy other than maybe ... |
Why can't I comprehend what people say to me when there are other people talking in the background? | It's your brain trying to accept information from multiple sources simultaneously.
