Not many constants, in fact.

0150 — the code of a dash in windows; 0x2014 — the unicode of a dash. Also a lot of character codes, especially the CWI ones. In the DOS days, you had to know them. (I've forgotten them now.)

Powers of 2 up to 65536 (1 2 4 8 16 32 64 128 256 512 1024 2048 4096 8192 16384 32768 65536).

Oh, and 0 == SEEK_SET.

Update. It seems that no-one has mentioned 273 K ~= 0oC. Also noF == ((n-32)*10/18)oC. And 1 in == 25.4 mm.

Update. Yes, I know my social security number too, although that's of no use.

    [Corion]: I would assume so, but I don't really know Tk
    [kcott]: Actually, no. A 1x1 is 0,0 to 1.1; 100x100 is 0,0 to 100,100.
    [kcott]: s/1.1/1,1/
    [Discipulus]: ouch! so 100x100 is really 101x101 pixel.. ;=(
