Powers of two

[ciphergoth]

I can't remember what made me think of this, but there's a bit in Snow Crash about powers of two, and I wondered if things had changed, and that people deal in higher level stuff than this these days. And it's just striking and a bit weird anyway that some people have had occasion to memorize this stuff, I wondered if you had...

Update: The "powers of two" are just 1+1 = 2, 2+2 = 4, 4+4 = 8, 8+8 = 16 and so on.

Update: it seems like it isn't clear from the above, so for the avoidance of doubt, no-one should feel that they should know this off by heart!

I don't know what one is. :(

I was an oddity in high school - top sets for science (extra classes and everything!) and third set for maths. No one else was in anything less than top set for maths.

3rd set out of how many sets?

4 or 5 i think. I got moved down from second because i was so underconfident i kept moaning that it was difficult - unfortunately, in retrospect, the teacher shouldn't have listened to me and should have encouraged me more. I think i should have been ok in the second set with a bit of encouragement, confidence and hard work.
