nice google save

i don't really understand if you are trolling or not

Captain Cannabis · 06-12-2011, 10:53 AM

right, so do you care to understand how those facts were calculated or are you just trying to impress that you were able to find them?

also textbooks are a huge scam and anyone who has ever bought or read a few knows that.

I prefer my physics to be theoretical.

Captain Cannabis · 06-12-2011, 12:21 PM

nope. i only remember when i learned it. i have all my notes and references organized well enough that i can find it.

Stephen Hawking can do the math for the physics of black holes distorting space and time in his head. If he can't do it, he is probably pretty fucking close.

phd physics professors can remember the formulas.

its like asking a painter to remember all the colors and how they mix.

if you understand how the formula is derived then its not so much a memorization task as it is a task of understanding how each part of the formula can be manipulated to give you which ever quantity youre looking for.

i didnt just google the temperature because the suns temp is not really 6000k like the problem says and i needed to show work in order to get any credit. of which im probably only getting half

Captain Cannabis · 06-12-2011, 12:39 PM

so what did you calculate for the solar flux density?

**Mafoo** · 06-12-2011, 12:49 PM

please dont judge if ive made any extremely dumb mistakes, i worked the problem several times, got extremely stressed about my other finals and gave up.

El Coyote · 06-12-2011, 04:26 PM

I agree about the textbook scam. Prices are ridiculous. Sometimes the books costs more than the actual fucking class!

**Mafoo** · 06-12-2011, 04:31 PM

word. i can kinda justify spending that money on science texts because you really can keep them and refer to them for life.

but for like work books and lab manuals, seems like tuition should cover some of dat ish.

i was real mad last week when i tried to sell my books back and they said new editions were coming out. new editions are the biggest scam running

Captain Cannabis · 06-12-2011, 04:35 PM

new editions are almost as big of a scam as textbook buybacks

you didnt really show your work for calculating Asun and such things. you can get mad partial credit for the same incorrect work. i ended up with 109C after correcting a small error near the top of the page and making some of my own later.

El Coyote · 06-12-2011, 04:44 PM

Hahahah new editions are a joke. Especially when it's pretty much the same book but with a different cover.

**Mafoo** · 06-12-2011, 04:52 PM

same book different cover, higher price.

seems like a fairly elementary scam

El Coyote · 06-12-2011, 04:59 PM

The worst is when the professor tells you on the first day that you are definitely going to need the book so you go out and buy it and you end up never even using the damn thing.

Captain Cannabis · 06-12-2011, 06:22 PM

i figured out my mistake. consider the sun as a disk instead of a sphere (cross sectional area).

so you're saying it's a burn
