math in review

By John L · February 3, 2010

functional analysis? c'mon son, get the fuck outta here with that shit.

combinatorial group theory? mmmmmm

i also wrote some reviews but i think if i ever try to do it again it'll just be a mess of symbols and i'd try to define a topology on samus aran's robo titties.

I thought Samus was a flesh and blood human. I didn't know she is really a robot.

I'm actually missing math now. Should start reading through my textbooks again because I'm starting to forget it all haha.

I thought about you the other night, bluberry. I was talking to someone on AIM and he was expressing his disgust over an argument he had with someone who was insisting that .9 repeating is not the same as 1.

its 3am and i can't sleep so lets see if I remember how it goes from about 4 years ago.

.999... = 1
let x=.999...
so 10x = 9.999...
10x - x = 9x = 9.999... - .999... = 9
9x=9 => x=1

or there's a way to express it as a cauchy or geometric series that gives the same result. Man i'm rusty :(

it's not really a pet peeve. you just end up knowing that the person you're arguing with is retarded. you can prove it with 8th grade algebra, and if you want to get fancy, it follows from constructing the reals whether you're using dedekind cuts or cauchy sequences of rationals.
