This is what I get for skimming an entertainment website for a momentary diversion.

So, everybody’s seen the cool new video, “‘Cantina Theme’ played by a pencil and a girl with too much time on her hands,” right?

And we’ve heard the claim, via Mashable and thence The AV Club, that the formula “can actually be used to determine the speed of light,” yes?

It’s a joke. The “proof” is words thrown into a box and filled with numbers so that nobody reads it too carefully. The algebra isn’t even right — hell, it does FOIL wrong — but that’s just a detail. I tried to think of a way to use it as a hook to explain some real science, as I’ve tried before upon occasion, but there just wasn’t any there there. The whole thing is goofing off.

Obvious goofing off, I would have thought. Somewhere south of a Star Trek Voyager technobabble speech. But no, never underestimate the ability of numbers to make a brain shut down.
