ITT: stories involving TAs

>TA in algebra
>hand-in asks you to state and prove lagrange's theorem
>one student writes "... since the cosets divide G up into n parts .."
>put a cross next to that piece to indicate that's not exactly what's going on
>proof was okay otherwise
>still gave him full marks on that one because without the full marks he'd have failed the hand-in
>after the corrected hand-ins are handed out, he comes back to me to complain about exactly that
>tell him how he needs to think about in terms of equivalence relations and cells
>he says we're both right and that he'd write his version on the exam
>let it go

Man, I really wanna help these people, but this fucking cunt reeee

ITT: We share stupid technological ideas that we've come up with.

Other people will then explain why your idea is stupid.

I'll start.

>find area of ground that's above sea level and surrounded by higher ground
>pump in a shitload of water
>build aqueducts at the minimum slope to an area with lower ground, and turbines at the end of the aqueduct
>when solar and wind are producing more energy than the grid is consuming, use the power to pump more water from the ocean or nearby rivers up into the basin
>when the grid is consuming more energy than wind and solar are producing, drain water from the basin into turbines to generate more electricity
>in effect, turn geological features into giant batteries, without needing to shell out for anything other than piping and machinery

What are your thoughts on meat consumption?


>On the way that I'm thinking, it seems that the massive production of meat for our needs is, from an evolutionary standpoint, advantageous for the prey as the species is being perpetuated thanks to our actions.

>be in a biotechnology group about designing a factory for cleaning using algae in waste water to produce biodiesel
>only none brainlet in the group
>brainlets take tons of responsibility everyday and have nothing worthwhile to show for it the next day
>one day left to hand in the project
>tell everyone that I'll finish the project myself
>They tell me that I can't possibly do it myself
>tell them we will fail unless I do it
>fuck off home and delete everything they wrote
>8 hours later the project is done
>brainlets ask to correct it
>They convert it from word to pdf and send it without my approval

>I answer all the questions posed by the professor
>he tells me that he wants to ask the others now
>he asks them if biodiesel is a high value product or a low value product
>They can't answer
>he asks them the limitations of using hexane to dissolve the lipids are
>They can't answer
>professor finally says that the project was good enough and somewhat close to what the other groups did (their projects were way better and they had worked for 2 weeks on their projects while I had to do it one day)
>brainlets bad mouth the professor after the presentation

How do I control these fucks?
This is the 4th semester. They've failed multiple classes but I still fear there's a chance they'll get their degree.

How many diagonal rectangles are there in an 8x8 chessboard such that each square does not share a row or column with any other of the 3 squares?

The picture has some examples of valid rectangles.

I got 75 rectangles, but am curious what other people got and how you approached it. I will show my work if you would like.

Question modified by Elements of Discrete Mathematics, 3.35 - CL Liu. I purchased the book from a used book store and have been working through problems in my free time.

How are the PhD prospects in Math and Physics in the USA? I'm a third-worlder (Brazil) and I want to escape from this shithole. I'm also a semi degenerate gambler and my income comes mainly from poker, backgammon, pool, bridge and sports betting. So it would be pretty cool to work in something related to statistics/probability and game theory (or thepretical physics) . As a third-worlder it is easier for me to join in a PhD program in Math or Physics in America? And which PhD offers better prospect AFTER its conclusion?

P.S.: what are some good universities close to Las Vegas and Atlantic City?
