By the bankers axiom.

Buy at 2 Lend at 3 Go home at 4.

When you deposit money in a bank it isn't really in your account. The bank uses the money people have deposited in invests in things, from giving out personal/business loans and mortgages to buying stocks and shares or even buying and selling debt. The profit they make doing this covers the bank's operating cost and interest on your account.

Essentially when you put your money in a bank you are in actuality loaning the bank your money.

This is why when banks collapse people loose their savings. The bank gambled with your money and lost it all.

Pressure is defined as force per m^(2). So you can just get a piston of known size (say, 1 cm^(2)), check the force pushing on it, divide the force by size and then convert as you wish.

Also, strictly speaking kg/cm^(2) isn't a physically correct unit of pressure, it's implied that weight in normal gravity is used. "1 kg of force" is actually 1 kg * g (free fall acceleration on Earth, ~9.8 m/s^(2)), so 9.8 N of force.

It's also true for cars driven at high altitudes. A naturally aspirated engine makes less power in the mountains than it does at sea level. Turbocharged cars can make up for that for the most part by just pushing more of that less dense air into the engine, so the power loss is much less severe.

That's fundamentally wrong. More frames and the information displayed on your screen will be newer.

For the sake of simplicity, let's say you had 1hz screen and GPU producing 1fps. By the time a frame would appear on your screen, it's already 1 second old. You get to see the frame that was generated 1 second ago.

Now, if you had 4fps, the frame you see would only be 0.25 seconds old.

Linus had a video a while back, comparing 60hz and 60fps vs 60hz and 240fps. The difference is MASSIVE.
