My friend asked me if you stopped time and you spin a coin and you start time back. would the coin begin to spin faster?

I insisted on him making an account but he was resilient.

sorry for breaking a rule?

This is really an unanswerable question, since we can't stop time. However, there are some reference works you or your friend may want to peruse at the library:

The Girl, the Gold Watch, and Everything by John D. MacDonald
The Man Who Folded Himself by David Gerrold
"A Kind of Stopwatch" by Rod Serling, a Twilight Zone episode

Not only that, but how do you spin the coin with time stopped? Wouldn't everything be 'frozen'?

...how do you spin the coin with time stopped?...Hold the coin in one hand, the stopwatch in the other...click, spin, click---see the coin spinning slower... http://www.bautforum.com/images/icons/icon10.gif

The answer is yes. The reason is that the coin can't spin if time is stopped. With a "stopped" spin rate of zero, of course it's going to spin faster when time starts back up again.

What action do you take, while time is stopped, to start time back up again -- and how long does it take?

If you can stop time, you can probably do anything. If.

Look at the idea the other way around: You're not stopping time, you're speeding yourself up. In this case, you would impart a great deal of energy to the coin, which it retains when you slow yourself down again.

See "The New Accelerator" by H. G. Wells.

Good point. But of course the coin has to be in a spinning state before you stopped time. I think the OP means to spin it after time's stopped; i.e. it's the only thing moving when time stops.

Which is it Chunky?

So while time is stopped, how is the rate of spin determined? Without a change in time, speeds can't be measured (since speed is distance/time).

why would i have to spin the coin before i stopped time?

That seemed to be implied in your question whether the coin would spin faster, since it reads as "spin faster than before time was stopped" which implies that it was already spinning.

If instead your question was "will it spin faster that it did while time was stopped?" the answer is indeterminate, since "how fast is it spinning?" is answered by "'it turns that much' divided by 'in that much time'"; when time is stopped, all you have for spinning speed is 0/0 which can be anything.

Jeez Chunky, the harvest is in, is it? :)

Stay tuned for next week's Stoner Group discussion: Is the solar system actually an atom in the thumbnail of a giant?

BD, that's not a nice response.
