Hi /sci/ I'm taking a babby QM course (not rigorous or anything, mostly just a survey of elementary topics) and I'm being asked to normalize the wavefunction for a ground-state particle inside a cube of sides L. Wavefunction is top equation. I've never normalized a multivariate function though. Would the procedure in the second line yield the normalization constant? Is it as simple as just integrating with respect to each variable from 0 to L?

Why are professors such assholes to undergrads? In chem class we learned about van der waals equation and I decided to spend the summer coming up with my own version, it didn't make a massive amount of sense but it was actually more accurate for calculating the Boyle temperature of a gas which isn't groundbreaking but pretty amazing considering I just started studying a year ago. Anyway I took it to my professors who all proceeded to completely ignore me. I didn't want a medal, all I wanted was them to discuss it with me, why it worked, how it could be improved, how I can use these skills in my studies etc, but nope I was straight up blanked. Honest to god it would have made my day if they at least replied saying "haha it's bullshit" because that would be feedback of some sort. But no no reply whatsoever, most aloof fucks on earth.

One of my professors supports Anita Sarkesian and the rest of that group, going so far as to talk about it in class. Should I tell the Dean?

So many here think they are genius level. Some are grasping for knowledge they will not understand just now. Anyone who has a grasp of the magnitude of the undertaking of mathematics and physics will appreciate how little they know. Before this is disregarded, I am a physics student and I want rigorous mathematical and physical viewpoints. Discuss.

Does this look right to you guys? or did I do it wrong?

God is a delusion, a false hope, a crutch. There is evidence that shows the human mind wants to instinctively believe in a divine/higher power. However scientifically, there is not a reasonable amount of evidence to show God exists. God cannot be proven to exist, therefore, we should not believe in God. People may want some God to exist, but when we learn about the world and think logically, we discover it is an irrational/unscientific thing to believe in God. -------------------------------------------------- Furthermore, any value placed on life is a delusion, a false hope, a crutch. There is evidence that shows the human mind wants to instinctively survive and continue living and breeding, but scientifically, there is not reasonable amount of evidence to show that the constant pursuit of self continuation and replication is something that should be done. Why continue surviving? Being alive, you feel chemical reactions in our brain cause us joys and pains. But being dead you would have no desire for any pleasure no the desire to eliminate any pain. Why continue breeding? People do not need to exist. The human race does not need to be continued. We are biologically/genetically/chemically programmed/conditioned to want to do these things, but that doesn't mean we should.

Alright /sci/, here's the deal: I need an article/report/whatever on a recent scientific breakthrough/discovery. I need it to be simple, I need it to be easy to write a quick page summary on. Thanks guys. pic unrelated

So, is this a real thing, or is it just bullshit? http://www.lockheedmartin.com/us/products/compact-fusion.html "Building on more than 60 years of fusion research, the Lockheed Martin Skunk Works approach to compact fusion is a high beta concept."

Math Learning

Hi /sci/, Is it normal that one has to do a ton of exercises to learn the material in math courses? I find that I cannot just read a chapter and absorb the information that way; I gradually learn from doing exercises. Is this normal, or am I just really slow?

Made my first webm. Title tells you what it is... it's the new imaging technique by the guy who won the Nobel prize just a few weeks ago. Video is fucking amazing if you ask me! Anyway, post some science vids/gifs! ps: webm is a pretty shitty format btw, mp4 is a lot more efficient.

Any recommendations for linear algebra texts? I'm taking a power series and linear algebra combined class called "Matrix and Power Series Methods." The book is terrible and written by some jackoff professor at my uni. pls halp. also general linear algebra discussion
