The Big Bang Theory is also known for using real science and equations, as I have noted before. This week Anne McCoy, who is a Deputy Editor of the Journal of Physical Chemistry A, told me about another prop, shown below, a Festschrift issue for Sheldon Cooper.
The story of how this came about is described here. It is not totally accurate, because these Festschrifts are normally for people on their 60th birthday and Sheldon is a string theorist, at least until recently, not a Physical Chemist.
Below are a couple of screen shots from the show where you can see the prop in the background in Sheldon's office.
