re: Scientific notation on the Internet.
You can probably get software that transforms your regular keyboard into a math symbol generator. I used to have one for the Greek alphabet, upper and lower case, many fonts, and so on, and it worked with any editor. This included all the accents, diacritical marks, etc. in that alphabet. There was a template that fit over your keyboard so you could type in text as fast as if it was English (provided you knew Greek).
