How did the modern version of the globe come to be, with what we call North on the top and Souyh on the bottom? | [
"In actual fact nobody really is sure as to which side is north and which side is south. In Australia for example, globes can be purchased that are flipped with the southern hemisphere appearing above the northern one. I believe the reason most globes are the way they are today is largely down to the British empire... | [
"The Prime Meridian (0 degrees longitude) runs through the UK and is usually right in the center of a world map. To the right are the eastern longitudes, and to the left are the western longitudes.

Why do we experience brainfreezes when we consume cold drinks too fast? | [
"Brainfreeze is caused by your nerves not being totally connected in obvious paths. The trigeminal nerve serves the forehead as well as the roof of the mouth.

Why aren't baseball fields all the same size? | [
"Because the rules allow for stadiums to design fields within certain parameters. That design is in order to benefit the team. Baseball teams play half their games outside of their own field, so it evens out. Every team gets half their games in their home field which is tuned to their advantage. The result is that ... | [
"> Doesn't this give an advantage to players and teams with a home stadium that has shorter distances to the outfield wall? Nope, both teams play on the same field on the same day.

If I went to a horse race and bet the same amount of money on every horse, would I break even? | [
"Well, imagine if you bet $5 on every horse, and there are 10 horses. That means you've spent 50 dollars. That's always going to be the same every time, no matter who wins.

Why did ancient multi hundred year civilizations barely advance tech wise? | [

Why do hatches and SUVs have rear windscreen wipers when Sedans rarely if ever do | [
"The aerodynamics of all cars creates a bubble of air behind them causing a loop affect when it rains. This loop effect causes rain to splash back on to the rear of the vehicle. In an SUV or other trunk less car, this means it splashes onto the rear windows. In a normal coupe or sedan, the rear is the trunk which g... | [
"Typically, the rear door is obstructed by the wheel well. As such, there is not room in the door for the window to go down all the way. Some cars without that obstruction (SUVs for example) typically will go all the way down."
