Why does it feel warmer when it’s snowing outside, compared to it just being cold without snow?
Bunch of wrong answers here... Snowfall implies negative degrees celcius (otherwise it would rain). As the temperature drops below zero, the humidity in the air quickly drops aswell.
Why do you often feel to hot/cold when you want to sleep?
Your body temperature decreases to initiate sleep. The recommended temperature for a good night’s sleep is 60 to 67 degrees. That’s a lot lower than what I think most houses are at right now.
Why is water a liquid at room temperature, yet hydrogen and Oxygen, which are the elements water is made of, a gas at room temperature?
Hydrogen and Oxygen are both positive, but oxygen is more positive. Therefore the oxygen atom in water holds onto the electrons most of the time. Because of this, the water molecule looks little bit l
Why are electronic language translators so bad at their jobs?
The sentence "Go take a run." has some 1200 base meanings without any context. The word "set" has over 400 definitions. How the hell is a computer supposed to figure out exactly which one you mean whe
Why do Black Lives Matter protesters only show up for police-involved shootings? Why are black-on-black shootings ignored?
The protesters aren't there just because people are dying or because they hate "shootings". Black lives matter is about a particular issue - injustice at the hands of the people / systems that are des
Why do airlines force people to keep their seat belts on for so long when people in private planes can lay down, sleep, party, etc.?
Seatbelts aren’t just for collisions or sudden stops while taxiing. They are primarily there to keep you in your seat in the event of bad turbulence. Turbulence can happen suddenly and without warning

> Nobody goes around saying "Yay! I get to change my clocks! This is the best day since spring!" But that doesn't mean that most people hate it.
Why do all in-flight map screens seem to utilise the same laggy style and design in this day and age of Google Earth?
The computers on planes are years old because of the extensive and time-consuming safety testing they have to undergo, plus the delay in getting them installed (the airline doesn't like to take the pl
Why do some electronics have lights to indicate that they are off?
Electronics don't have lights to indicate they're off. If they are off then by definition there's no power to run the lights. However, some electronics *do* have lights to tell you they're on standby
Why is it that food has to be refrigerated to keep it from germs, but if our body catches a cold it gets germs?
When our bodies get cold, our immune systems get weaker. So cold viruses have a better chance of infecting us (especially when everyone around you is sick). As for food, bacteria tends to breed best b
