This is why I love Futurama. In less than two minutes they cite Lorentz invariance, refraction, and Schrödinger's cat. It should come as no surprise how science savvy this show is; the writing staff is stacked with scientists and David Cohen, one of the co-developers, has degrees in physics and computer science. From this 2007 Wired piece:

Futurama was geek-friendly to begin with: Episodes are built around sci-fi staples like parallel universes, spaceship battles, and time travel. But look more closely and you'll spot fleeting jokes that are geekier than a Slashdot comments thread, gags about the Heisenberg Uncertainty Principle, particle physics, and the P=NP problem.

There is also this excellent interview by SEED magazine with the writers of the show.
