"Something something four foot three. Got it."
I've talked about what Grace is talking about in commentaries before, but I'm pretty sure I haven't flung it into the comic itself in this sort of detail. Grace rounded up, but she's mentioned the results of the cubed root of 1/2 before. And it's a good thing this commentary reminded me that it's the cube root we're concerned with, as I almost posted this with her saying "square root" in panel two.
One of the reasons I bring this up now is that I'm not likely to have a Q&A anytime soon, and a relatively recent EGS:NP resulted in questions regarding whether Tedd had figured out how to go beyond previous size change limitations. He hasn't. The cube root of 2 is about 1.26, i.e. the "26% bigger" Grace once referred to. Half and double-size has been within Tedd's reach for a while now.
Have I mentioned that I probably would have loved math classes if they actually gave me something fun and / or useful to apply the formulas to? Well, yes. I know I have, but it bears repeating. I can't even remember what the quadratic formula might be used for. I'm sure it's used for something, but I mostly remember a sea of contextless numbers and something something graphing calculators.
Darn it. I LIKE graphs. I'm betting there's something fun I could've done with it.
