When you only roll down two windows in the car, the crazy noise/pressure thing.. | [
"You're basically changing the inside of the car into a big organ pipe. The air rushing past the open window starts the air inside the car vibrating, just like when you blow on a musical instrument. Not all cars do this; the interior needs to be the right shape and rigidity and \"air-tightness\". Some do it with o... | [

After a company like Twitter does an IPO and sells itself to the public, how can they then issue new shares in the future? Where do these new shares come from? | [
"Twitter didn't sell all of its shares in the IPO. It sold only 10% or so. Some of the rest of the shares are owned by people who founded or invested in the company or otherwise got in early. The rest are owned by the company itself, and many of those are locked up in stock options and RSUs."
] | [
"Because there is no special privilege given to the founder of a company that is publicly traded. He’s a shareholder like everyone else. Or are you asking why he allowed other people to buy shares in his company? Money. Shares are sold to raise money to invest in the business."

Why do I perceive differences in warm temperatures better than I perceive differences in cold temperatures? | [
"Your nerves are more sensitive when they are warm (that's why you get numb when it's cold; your nerves are becoming less responsive). In the 50 to 80 degree range, your nerves are much more sensitive than in the -40 to -10 degree range. Hence, you detect the difference more readily when warmer than colder."
] | [
"There are a lot of factors that could cause someone to feel more warm. First of, variances in standard body temperature can mean that his body is as much as one an a half degrees (Fahrenheit) warmer than yours, with the difference being different metabolisms or diets. Additionally, your body temperature fluctuates... | eli5_question_answer | {

Why do people need to care for their teeth but animals don't? | [
"I've heard a theory that if we ate what our ancestors ate in the paleolithic age, our teeth would look a lot better. They wouldn't be perfect, but neither are animals' teeth. This means that instead of eating lots of refined sugars and starches, we'd eat meat, fish, nuts, leafy vegetables, fruit, and nuts."
] | [
"Because both things (good teeth and good skin) don't just occur naturally - they require you to take care of yourself, have a healthy diet, etc, etc Generally if you take care of your skin, you'll also be the sort of person who takes care of your teeth. And conversely if you don't take care of your skin you're pro... | eli5_question_answer | {

Why do teeth need to have sensory functions? What evolutionary purpose does that ability have? | [
"If you bite a metal bar you can tell it's too tough to chew. Without nerves you wouldn't be able to tell and would end up breaking your teeth"
] | [
"Humans used to have bigger jaws so they would have fit. These days our jaws are shorter and we don't tend to lose teeth which would make room for the new ones to wedge their way in.

How can 20 year old movies like Jurassic Park and Terminator 2 have really convincing special effects, whilst the CGI in newer films looks completely unrealistic? | [
"Well to be honest there are some movies that are just one big special effect ( Gravity or Life of Pi ) that look extremely realistic. CGI is basically an art form you can think about it like painting a picture. If you rush an artist and only pay him little money your picture will look stupid even with the newest t... | [
"As a reddit *elder person*, who, by definition could have teenaged grandkids, I, too, am utterly baffled how Star Wars survives 35 years after it was initially a special effects tour de force. In it's day, it held a special place, but come on, surely it's old, lame and mostly irrelevant by now."

why do some songs give me an intense physiological reaction whilst others don't? | [

Is it legal to record someone (say, doing something funny on the street) with a camera? In what situations do I need their permission? | [
"Generally speaking, if you are in public, you can record anything you can see or hear. Exceptions may potentially apply if you're using extremely powerful telephoto lenses, as an example, or parabolic microphones, but with something like a cell phone, nothing you can see or hear from a public place is produced by ... | [
"1 - These laws vary by state. In some states it's OK for one party to record the other without informing the other party (called \"one party consent statutes\").

What is it about fast food that when eaten late at night, gives your stomach that hangover feeling in the morning? | [
"probably the beer that prompted you to eat fast food late at night? i'm just kidding. Most likely: this might be something that is unique to you (or a grouping of people with the same experience). it could be that your body is having a hard time processing junkfoods like that, and is reacting adversely, and not ... | [

The exact purpose of histamine, and why it can become harmful to allergic peoples? | [
