OK, this is very strange. I find it unlikely that all three people who said they would send me gmail invites (Pinyan, Annie, and, wait, who was the third?) failed to send it, so more likely one of my various ad-hoc spam filters (I should really just get a real spam filter, shouldn't I? It would work so much better) is catching them all, for some reason (can't figure out what). I don't know if they're resendable if the person hasn't actually accepted yet; if they are, could one of you resend? (I've set it to let through anything from gmail.com.)
So, Dr. Nevard gave us the Parallelogram Law problem (for extra credit) today. (There is no reason for you to read this paragraph if you've been in his class before.) The problem is, he proves in class, if you've got a norm on a vector space from some inner product, then |a+b|²+|a-b|²=2(|a|²+|b|²) (the Parallelogram Law); then he says, assuming this is a real vector space (he says you can probably do it for complex as well, but he doesn't know how so, if possible, it's probably considerably harder (he said if you *can* do that, that could be extra extra credit)), given a norm on it that satisfies the Parallelogram Law, show it is generated by some inner product. Actually, he says, figuring out what function you want isn't as hard as then proving it *is* in fact an inner product. This certainly seems to be the case; in fact I think I already know the function, and proving positivity and symmetry is trivial, but proving this thing is bilinear looks just plain scary... he said last year, Jon Chu managed to get it but Jae Bae didn't.
He also gave us our first quiz in AP Comp Sci, which nearly all of us got at least mostly right. He was amazed that for once he didn't overestimate his students.
The other day I tried to find a new locker down on the 1st floor senior hallway, but every locker I tried that had no lock on it was already taken. Yay. Looks like I'm going to be carrying my lunchbox around all year. (OK, so I didn't try every locker. I can try again and probably will at some point. But it seems pretty unlikely I'll find anything.) Chandi actually offered to store my lunch for me, but really, I'm not going to go keeping my lunch in someone else's locker... {even,especially} if they have no lock on it...
I put up an index card on my locker listing all the active players in Nomicron, there scores, acceptance indices, and the product of the two, sorted descending by the product. (No, I don't expect people to understand what it means. Why do you ask?)
So, apparently the new senior lounge is room 145. That room scares me.
