Why it’s relaxing to sit in 100+ degree (F) water, but is uncomfortable for air temperature to be that high (especially when humid). | The upper part of your body is still exposed to the cooler air, and being wet, water will evaporate from it, cooling it down further.

You would test your compiler by bui... |
What is the origin of the irrational number "e", and what significance does it have in the mathematical world? | Ooh! I know this one! I had to figure it out myself, because it seems that every math teacher either doesn't know it, or forgets to mention it. e is special, because it is the only number n such that every point on the graph of n^x has an equal value for slope and y coordinate. That is to say, if you have a function e^... |
Why does it seem like banks (and most places with cashiers like grocery stores for that matter) are always understaffed? | Because odds are that you go there when most other people go as well. You see it as busy and understaffed but had you gone maybe one hour earlier or later the place could be empty. If these businesses hired more people for busy times, which might only total an hour or two per day, their costs would rise. When the cost ... |
What is the H1-B visa program and what impact has it had on the US and Indian economy? | The United States only wants to take in so many workers from other countries.

Why can't you buy normal gas can pour tops anymore? | It's illegal to make and sell the "old-style" gas cans in the US now.

Why are ovens regulated by temperatures, but the cooking plates are regulated by numbers? | Because an oven is a fairly controlled situation. There's no air circulation from the room . More importantly, there's no escape of heat from a poorly insulated pan. The oven is fairly well insulated to prevent excessive heat loss. But probably the most important thing is that an oven has a *feedback* mechanism. Beside... |
how do we know if the premium fuel we pay extra for is actually premium | Well, I think you misunderstand premium. > It could be all unleaded but sold at 3 different octain levels That's exactly the difference between unleaded, plus, and premium: the octane level.

Once the cells die, the pumps stop working, the membranes lose their integrity, an... |
If i breathe in steam in the shower, why don't i drown? | It's really not that much water. The whole lining of your airway and lungs has watery stuff stuck to it .

How does an automatic transmission works | [Seriously, you're not going to get a much better answer than at HowStuffWorks.] They have really good videos and graphics that explain things very simply.

What to look for when buying a motherboard | I would definitely recommend /r/buildapc for help with this, but there are 3 things I would look for, depending on what the pc will be used for. 1) CPU Compatibility.

Why can't we do something like a "semi optional" tax system in the US to appease everyone? | If *any* kind of tax were made optional, the vast majority of people who only care about looking out for themselves would choose not to pay those optional taxes.

I'm no expert thoughAthletes take a stutte... |

Why is anything after 15 reps considered an endurance workout? | 15 reps isn't some magical number where your body's muscle-building effectiveness goes away.

They quickly flip back and forth betw... |

Does cheese have a latent heat of melting, like when ice melts it stays at 0C during melting and freezing even while the system adds or loses heat energy | There are two ways to go between the solid state and the liquid state: At a melting point, where the temperature of the body doesn't increase, and in a melting trajectory, where the temperature of the body does increase during the melting process. An example for this is cheese, chocolate and butter: They consist of dif... |

why do interracial babys get skin colour genes from both parents instead of just one. | I think you kind of answered your own question.

Why is it important to turn off your eletronical devices (especially computers) ? | Electronics more frequently die during a power up or power down scenario, as power supplies often spike during these events.

Many beauty, cosmetic, hygienic products contain oils from nuts. Are people with nut allergies susceptible to others who use these products? | As a person with anaphylaxis my answer speaks to experience only.

Why is it still illegal to pump your own gas in some states, like New Jersey? | I find that it's more about keeping people in work.

Unions fought to ha... |
Why are mega stores like Walmart so huge? | Good question. The buildings are so large because people want all of their items at a one-stop shop.

Fighting fire with fire. | Controlled burns are used ahead of a forest fire. The ground is burned in a line of small fires before the out of control fire arrives.

If the wars in the Middle-East are so unpopular, what are we fighting and why don't we bring the troops home? | I'll start with Afghanistan first. As you know Al Qaeda attacked the US on 9/11.

Recently the Saudis announced a plan to transition their economy from an oil based one to one funded by a sovereign wealth fund.

How did women come to be treated like second class citizens is so many major cultures throughout history? | My guess is that women are typically physically smaller and weaker than men. In the past when physical attributes contributed more in terms of survival, men likely dominated women and as societies evolved the mentality of domination continued. |
Why do lawyers defend people like Anders Breivik (Norway killer)? | Money. Recognition. Because someone has to. In the case of someone who is clearly guilty, like in your example, the defence laywers job is to get them the lightest punishment they can get away with. They dont have to agree with the person they are defending, but they have to do their best. If they get caught not doing ... |
If 1=single, 2=double, and so one, is there one for 0? | Not really. In math it's known as an "empty tuple" or "empty sequence." Colloquially there was never a need to come up with a term for a 0-tuple. |

Why must PC and Mac games be developed separately? | Windows and OSX provide the tools that an application need to talk to the computer hardware itself.

What's the benefit of raising minimum wage? | Business owners still have to make money, so in many situations, yes, an increase in the minimum wage can force owners to increase prices to cover their loss in profits from having to pay their employees more. So yes, what he's saying makes perfect sense. In other situations, however, an increase in minimum wage will a... |
why do average people seem more attractive now than they did several decades ago? | Your definition of "attractive", generally speaking, is in part informed by current culture and fashion. Clothes from, say, the 70s look ugly to us, so people wearing them are seen as less attractive. Same with certain hairstyles - the Jheri curl, for instance, is a joke hairstyle now, but in the early 80s it was hot s... |
