Abacus constants list

A constant is a sequence of characters that does not end with a left parantesis, a colon, or a number. Since cells that start with a sequence of characters that aren't a reference to another cell are considered to be strings (and thus always evaluate to 0, should you try to evaluate it) this might cause undesired effects if you only type 'h' in a cell when you wan't it to represent planck's constant, for instance. In these cases, you should type in '=h' to emphasise the fact that it is a number (or reference to a number) that you have typed in, and not a string.
Ok, let's go on with the constants then:

HELP! Can you translate some of these constants? Please mail us if you can. Thanks in advance.
