Could you build a coin flipping machine that flips the same coin

>>9100595
theoretically i think yes but i think your problem would be applying exactly the same amount of force to exactly the same spot on exactly the same coin.

>>9100595
I suppose you could. I don't see any reason why this wouldn't work.
Reality is weird, though, so if it doesn't work there could be some other reason.

1. You would need to be in a vacuum

2. Even then the coin would lose integrity every flip

3. Also the machine would lose strength

It's been done.

Air currents, air density, table bounciness

>>9100595
of course you can.
the random outcome of the flip is created by imperfection and changes in the system between flips.

think of a round and and egg football/soccerball
drop the round one its predictable, all points are equivalent. the egg one will go in different directions every time but why? because of where it lands on the oval move it different directions. how does a different bit hit? because you drop oit differently, the wind blows it etc etc. if you could drop it on the same spot it would go the same way every time. same with the coin, control ALL of the parameters and it will land the same way.

Yes, if the coin is not flipped very far.

the channel tunnel was dug in 1980's
it is 50km long and dug from both sides
meeting in the middle the error was ~0.3m
i think if you throw enough money at it you can do whatever the fuck you want.
