If this counts as 'monkey analogs' writing Shakespeare, I should start keeping a list of words I say. Then when any new book comes out, if it can be written using only words I've previously generated, but not necessarily the same order, then I wrote the book. Only Dr. Seuss will be safe from my litigation.
I've always wondered if it would be difficult to make a voice recognition program integrate mathematical symbols. Even though those symbols exist as a shorthand, fields with underdeveloped notation can be a little cumbersome for writing. Anyone who can make my pen obsolete by accomplishing this can claim it as a prize.
I should answer A because in that case it is impossible for me to invalidate any other choice. That way everyone wins!
Give me a long enough lever and a place to stand and I can move the earth. I can not, however, move your mother.
My favorite is a TI-89 emulator, because when I use a calculator I'm usually not in it for the general operations. Unless you count Mathematica as on-screen (and as a calculator). But I guess anything that can make graphs and calculate their diameters and girths for me isn't a 'calculator.'
