E means "times ten raised to the power" (as, indeed, it says in the 
wikipedia reference below) which is not the same thing as "raised to the 
power of ten".

> 1E-12 and 10^-12 are the same number, specifically 1,000,000,000,000.

You mean, of course, 1/1,000,000,000,000

> 10E-12 is one order of magnitude (ten times) larger.

(... than 1E-12) - correct.
