Well, the revolver is very simple, and so reliable. Some people like them for target shooting, because they do not have recoiling parts. Certain very powerful bullet types are made for revolvers, I'm not certain why. I'm not really a gin expert.
 
A revolver will operate longer before parts break as it has less of them and they are individually simpler. They are less subject to jamming/malfunction and have simpler maintenance. Target shooting is a good use for them.

If you are looking for advantages between the two for their intended use, killing a human, a pistol with a clip will likely outperform a revolver in every aspect. It will hold more rounds, it will fire them more quickly, and it front loads much of the reloading time into filling replacement clips which is done prior to use rather than during use such as a revolver requires.
 
Is there a way to calculate what percentage of the earth's surface you can see from a certain altitude? We are assuming the earth is a perfect sphere.

I figured out the distance to the horizon formula but I can't get the % of the surface.

(radius of earth)^2 + (distance to horizon)^2 = (distance to horizon + altitude)^2

No this is not a school assignment. I actually enjoy this type of stuff.
 
Roughly speaking, you are seeing a circle of radius (distance to horizon), so you can do (area of your circle)/(surface area of earth) to get the fraction you want. This works okay as long as you aren't too high up. Higher up is more complicated, but it can be done.
 
Another question. As some of you know I bicycled Stockholm-barcelona-Rome-Stockholm last summer. This summer I am doing a few short trips but no long ones. However next spring I want to do north America. I am considering cycling from Orlando to los angeles with a start in march to june. How is the weather? How lonely will the roads by in Texas/new mexico/arizona?

How dangerous is southern USA? Are there any cities that are no go zones for a guy on an expensive bicycle?
 
The Southwest is relatively safe. But look into distances between stops. You could easily find yourself crossing 100 miles of desert without any water but what you brought with you.

Weather should be fine.

Safety wise, I think there's always that risk, being alone and such, but there's nothing out of the normal (mafiosos, etc.) to worry about.

Yeah, as the other two said, the thing you'll probably have to worry about the most is the desert in the Southwest.

I'd suggest watching out for meth fiends and drug cartels, but pretty much everything I know about the Southwest I learned from Breaking Bad.

Hey, speaking of Breaking Bad, is chemically pure blue crystal meth actually a thing?
 
If the Earth suddenly stopped spinning, would I fall over?

This was a joke on Reddit, but I'm actually curious.
 
No. Gravity would remain the same. I'm unsure of the math, but potentially you would actually get "heavier" because the centrifugal force of the planet's spin is trying to throw you off into space. Just not very strongly. So you remove the spin, you remove a force that is pushing you away from the planet. Not the one that attracts you towards the planet.
 
You would continue to be held down by gravity, but would also continue moving in the direction you were moving rather the ground below you moved or not. There would be considerable displacement across the surface of the Earth, at least until you hit something big enough to stop you. How fast you would move relative a non-revolving Earth depends on your latitude. If you were at the equator you would be moving at over 1000 miles per hour, but in Cascadia you would move closer to 570 miles per hour.
 
But everything else also stops moving in that direction. It'd be more enlightening to analyze what caused the Earth to stop spinning.

Anyway, is a nation flattening its own embassy in another country after evacuating it a provocative action? Or does bombing your own territorial exclave in this context have no international diplomatic implications?

I think that would be very situational. But generally the buildings are abandoned, not destroyed.

Along with everything else, you would retain your momentum. So you would go flying to the East. Think of wehn a car slams on its breaks, but going up to 1670 km/h (at the equator). Even at the Arctic Circle it is going 660 km/hour. If you were very close to the North or South Poles you might be able to keep your balance since your momentum would be so much lower.
 
Can you change a license plate's letters and numbers to something else legally?
 
I mean something like go to the DMV and say, I want to change my car's license plates. Can you do that?
 
You can pay extra to get a vanity plate, where you are allowed to choose what letters and numbers to use within certain limits. (You cannot choose something someone has already taken, and various obscenities and racial slurs are banned too.)

I'm not sure about just requesting a new plate with random letters and numbers.
