E^2=(mc^2)^2+(pc)^2

I just passed Physics 1 Honors so forgive me for any misunderstandings. With that said it seems that as the thickness of the coin increases it has a greater chance of landing on the side, even though the increase left it with a smaller surface area. So a coin with a diameter or 2.5cm would need a thickness of 1.44cm? I feel like there's some big thing I'm not getting though. Thank you for those links. They helped a lot and I'm still re-reading it.

Not really. It depends of what kind of assumptions you made to understand how a coin flip is made. It's been a long time since the question was asked, so I assume the solution can be posted without spoiling anything.
I'll not give you the solution, but rather how to understand how to come up with it. Just read the following links :

http://mathforum.org/library/drmath/view/52225.html for a first glance of the problem
http://www.seas.harvard.edu/softmat/downloads/2011-10.pdf for a deeper explanation (resources are given if you are interested in understanding the problem even deeply)

For Kurran's question: Would it be a cylinder with a height equal to the diameter of the face of the coin?

easy. we were all out partying, and we are just getting over the hang over.

scientists party hard !

I wonder why nobody posted anything about the discovery of a new boson on July 4, 2012.

I think it would probably look like a die.

A Pyramid?

Here's a fun physics question.

What should be the dimentions of a coin that has probablity of 1/3 to fall on its obverse (heads) side, 1/3 on its reverse (tails) side, and 1/3 on its edge?

No, I did not make this question up.  10 points to anyone who can figure it out.

I heard of it. I'm actually visiting the LHC on Thursday. :D
