Scientifically Accurate Details Fans Noticed In 'The Big Bang Theory'

From Redditor pyramerica:

These diagrams come from methods of partitioning rectangles.

These are a subset of 6-partitioned rectangles, you can see them displayed here.

This is from a field of optimization mathematics called the Packing Problem, probably more specifically Bin Packing.

From Redditor DaddyCatALSO:

Okay, there were two joint "Sheldnard" papers that I recall. In S-1 or 2, they wrote one on a semi-fluidic super-solid as a new state of matter. It wasn't stated fully, but I got the impression it took some very specific procedures involving specific lab equipment. The other, much more recently, involved a model of space-time as a fluid surface. A theory with wide potential for other theories.

From Redditor tiaraspace08:

Yes. They had two physicists on the set always checking the script. The equations and all the theories always written on the boards and everything were also always correct.

From Redditor mykidisonhere:

My psychology teacher used the episode where Sheldon reinforces good behavior from Penny with chocolates to help us understand conditioning.

From a former Redditor:

He's an engineer, not a scientist, which means he builds things instead of finding out why things happen. It's a totally different skill set that his scientist friends can't relate to. Also, while most scientists have PhDs, most engineers have MSs.

From Redditor shavera:

This is the equation of two particle scattering, probably through quantum electrodynamics. It won't have a numerical answer without values for p{1,2,3,4} but there are often a lot of assumptions we can make to reduce it to some kind of simpler expression. Without knowing those details though, it's hard to say.
