Penny: Sheldon, have you any idea what time it is?
Sheldon Cooper: Of course I do. My watch is linked to the atomic clock in Boulder, Colorado. It's accurate to one-tenth of a second. But as I'm saying this, it occurs to me that you may have again been asking a rhetorical question.
Near the end of the show, the big robot is chasing the other robot down the hallway. The camera starts to zoom in as the robots come by it. The big robot stops just before the camera zoom is past it, yet they keep running down the hallway like the robot is still going. See more...
Sheldon's laptop has gone through several strange transformations throughout the series, but in this episode it takes the biscuit - it appears to be a Dell XPS with the back covered up, but the shot of Sheldon chatting only to Amy shows that it's apparently running MacOS X. See more...

The entry you are changing the episode of is:
|Title||The Big Bang Theory|
|Original entry||When Penny and Leonard are talking to Sheldon about their date, Sheldon refers to Schrodinger's Cat, stating "The cat in the box is both alive and dead, until you open the box and find out." Yet the precise point of the Schrodinger's Cat example is that the cat cannot be both alive and dead. Schrodinger was arguing against physicists of the time who claimed that certain subatomic particles were special and could be in opposite states at the same time; his argument was that you can't make small systems special because a large and obvious system (e.g., the cat) could always be made to depend on the state of the smaller one, and for a large and obvious system to be in opposite states simultaneously is ridiculous. Now, this is pretty obscure and the misunderstanding of Schrodinger's Cat experiment is widespread, but this is Sheldon we're talking about. [This is not a factual error on Sheldon's part. He explicitly says that Schrodinger's experiment was an attempt to explain the Copenhagen interpretation of quantum physics, which implies that the cat could be both dead and alive until the box is opened and observed. While he doesn't explain that the point of the experiment was to critique the prevailing thought of the time, his overall point to Penny fits within the context as given.]|
