<3 XKCD.

What other webcomics are you guys into?
 





I just saw this 5 minutes ago - was about to post it, too. It's called "lasing cat-vity" :rolleyes:
 
That little mess/coil of resistors is almost REALLY, REALLY easy to solve, but one of the lines doesn't have a resistor on it. If that one line had a 1-ohm resistor like the rest of the resistors, then the whole thing would be 1 ohm, but that one conductor screws it up and I'd need to calculate the whole thing.
 
The xkcd forum had people calculating it.

They were getting around ~0.85 ohms with that conductor as a resistor, and ~0.77 ohms with it as written.
