omg i am So embarrassed. i just had this total crisis where i was completely confused about sample variance and unbiased estimator of variance and population variance, and i was going around asking people, and i kept referring to the population variance as theta squared, because it looks a bit like the theta from trig. and i thought maybe it was sigma squared but that didn't seem to make sense because the summation sign is called sigma and that doesn't look anything like the population variance thing. until i spoke to sophie's prc friend who was explaining the whole sample variance/unbiased estimator thing, and then after she explained she told me that by the way it's sigma squared not theta squared and she laughed at me! so embarrassing! and soph laughed too. such mean people.

[EDIT: oh oops it wasn't a PRC scholar, or it wasn't soph's friend, or something. i assumed it was her roommate. and she sounded nice. anyway yeah uh soph wanted me to clarify, but i'm not entirely sure if i clarified it properly. see her comment.]

i got laughed at by a prc scholar! DIE. (to be politically correct, i will clarify that i am kidding. anyway i think prcs are generally very nice, patient, smart people. and there is a very pretty prc girl that i sort of know on a smile-and-hi basis but i don't know the name of and soph can't be bothered to figure out who it is.)

anyway. the greek alphabet is weird and confusing. i googled it to figure out why there are two different sigmas, and it's because the summation is the upper case sigma, and the variance one is the lower case sigma. they look so different!!! confusing. but then 'A' looks quite different from 'a' so i'm just ignorant and stupid.

math makes me feel ignorant and stupid. everytime i think i can sort of do math, i look at some formula and suddenly it makes no sense to me (it's GREEK to me!!! HAHAHAHA. god i am really losing it.) and i feel really stupid and then i have to spend hours figuring it out.

one day i will learn greek and read the iliad or something. or maybe i'll just read Lysistrata, haha.

just so we can all learn a little bit of greek today:
