I need to play with a lot of powers such as 10^-3. 1E-3 does not work for it. Is there any short form for it?

I'm surprised there isn't a question about this (i.e. entering numbers in scientific notation) already.

To enter $3\times10^{-3}$, you can write 3*^-3.

For further reference, see Input Syntax: Numbers.

Yeah... it's indeed very surprising. Even Google does a bad job of leading to the correct syntax (of course that's before this answer became popular — now this is one of the top answers). – Shashank Sawant Oct 31 '14 at 8:44
