Ouais#0164: My name is the Schrödinger Equation, which is what is used to solve the wavefuntions of molecules, and find their position and momentum Ouais#0164: it gets complicated but if I can do it so can you kian#7919: ye my teacher explained that that's what the equation does kian#7919: he explained that if you squa...
tubbles#1226: for about any subject at certain times tubbles#1226: sometimes its interesting, but other times its the boring part of it manavpatel#8456: is the nuclear charge of an element related to ionic charge kian#7919: we were learning vsepr theory and he went and taught us orbital hybridization because he said it...
Ouais#0164: Nope, I almost flunked out of high school haha Ouais#0164: Then worked for a few years, then went to college kian#7919: Oh lol well good job for continuing your studies Ouais#0164: Haha thanks, I'm glad I went back to school best decision ever kian#7919: How old are you now?

Tangil#3830: Just kidding it's only mildly interesting Aces#1239: It's pretty much factually established isn't it? Aces#1239: I don't see where you hope to find discussion. Some people are just wrong Tangil#3830: No as in they have different uses Tangil#3830: Hanged is the past tense for when you refer to being put to ...

Yannoux#6969: someone needs to get back to school here ccman32#4022: i dont even know what log is anymore ccman32#4022: lol ccman32#4022: in the past 3 years i forgot about 90% of what i ever knew about math Yannoux#6969: log(x) is the inverse of e^x Yannoux#6969: by definition you would have log(e^x) = x ccman32#4022:...
ccman32#4022: and within 1 year i became the very worst XD Yannoux#6969: it took me 5 years to do something similar. ccman32#4022: i remember one teacher had a graph at his pc once showing my grades over time for the past years ccman32#4022: it went like straight down from top left to bottom right 😆 Yannoux#6969: xD Y...
Yannoux#6969: wiki says Polarkoordinaten ccman32#4022: you can probably explain more things to me in 1 hour than our match teacher in an entire year ccman32#4022: hm never heard of that ccman32#4022: where and when is that normally teached? ccman32#4022: maybe we didnt even have that Yannoux#6969: i have been thought t...
ccman32#4022: ffs i probably failed at this yet alone because i cant remember the terms for all of this stuff ccman32#4022: even if the actual calculations and math that needs to be done is completely trivial to do ccman32#4022: i get it then ccman32#4022: and what when you have 3 angles? ccman32#4022: like an addition...
ccman32#4022: for angular velocity doesnt that depend on how often the angles are applied then? Yannoux#6969: it does. but there are multiplied by a delta_time value. ccman32#4022: ah alright ccman32#4022: yeah i rememebr Yannoux#6969: *delta_time representing timing between frames* ccman32#4022: never had to deal with...
Yannoux#6969: we still have theory here. ccman32#4022: yeah but its sooooo much easier to learn with context and examples ccman32#4022: unlike someone tells you some formulas and lets you work with them while you have no clue at all what you even do or why Yannoux#6969: sure. that's what i hate about most studies. ccma...

Sciguymjm#5935: Deforming, depending on the use. You cant rely on normal elastic properties either.
