What are some hidden math and science references?

I don't know who else caught the fact that in one episode, I forget which, when professor farnsworth is at his childhood home, sleeping in his old bed, his blanket has the electrical schematic symbol for a transformer all over it. A transformers blanket. Get it?

Given that they had no less than three PhD's in math and science on the production staff, I suspect there were hidden references that haven't even been discovered. I know binary text has popped up multiple times besides Bender's mirror gag.

You know what noone tells you about cooking with the Dark Side? The food is really good!

Cool article. Thanks. Those math problems with $1,000,000 rewards always piss me off. I want $1,000,000 for doing a math problem. Stupid stupid brain.
