I have to hand it to gymnastics, which is running two nights a week now: it's capable of training me plenty hard without bothering my hamstring. I've been doing handstands every day at work, and when I mentioned that the teacher said he could tell I'd been working on them -- which almost has to be a lie, but a kind one. Anyway, I did handsprings in the harness on the trampoline again, then tried to take the front handspring over to the tumble track, where it promptly evaporated. Le sigh. Maybe that is what Wednesday is for; today is definitely a rest day. A rest, go to PT and have a date with my bug day.

I'm done reading Code now, and the book club at work is beginning to move into the book we're really covering. Near the end, Code was covering binary-coded decimal numbers, which meant talking first about binary numbers that fall between integers. These work about the way you might imagine -- the numbers after the dot represent negative powers of 2 instead of negative powers of 10. So, 1.1 in binary is 1.5 in decimal; 0.11 is 0.75 in decimal, and so forth.

That dot is referred to as a binary point. And I honestly thought it was a typo. What? There's nothing inherently base-10 about the term decimal point, I thought. Hello, does the "dec" in "decimal" mean nothing to you?

The Numerical Relations office is probably going to send me off to sensitivity training if they ever get wind of this.

Physical therapy this morning was really interesting. I've never actually been to PT before. I found out a lot about all the ways I'm asymmetrical: know thyself... know they flaws. )

I haven't talked much about my hardware studies, but I mentioned we're revving up for a book club at work in which we'll study how computers are built, from logic gates on up to compilers. I never studied this in college, so I'm reading quickly through a lighter book that covers a lot of the same material, in an attempt to be hitting the concepts for the second time in the book club. So, for the first time I understand why regular, static RAM requires power in order to retain its memory... some types like DRAM are even flakier, having to be refreshed often or the stored memory just fades out. And I wonder if human memory has anything in common with that. If so, all the cryo people are wrong, and it won't ever be possible to freeze a person and bring them back, because the electrical power in the brain will have been cut in the meantime, and all our little transistors / relays / quantum doohickeys will have reverted to their base state.

Memory is a spooky thing.
