arksterSo something cool happened in Topology today.
We were setting up this set:
X= {x ε (0,1) | x has no 9 in its decimal expansion}
and the prof explained that this was to avoid numbers like .3419999999... = .342
and I was all 'oh that makes sense, what with the infinitely small difference thing' and somebody else raised his hand and went 'wait, what? Why is .88888... okay, but not .999... ?' And I was all, 'oh shit, I get it!' Which is unusual!
Usually I am the one who does not get things, you see.
I don't get why we discussed Hitler in Plato-discussing class, though. I think for that it is just going to be a long year.
Y'all should have seen the omelet I made tonight. Brussels sprouts and mushrooms and onion, and I fried bacon in the same pan just to prove that I could. I don't understand why all this hate for brussels sprouts, they are awesome. Srsly you guyz.
