/b/ was completely useless in this. I'm working on a PDE and what I've done is pretty much just blowing up in my face (paper)?
No, it's not homework, just for fun, and I already have an answer. I'm more interested in how to GET the answer and what steps I should take, because I'm thoroughly confused.
Forgive my shit camera.
Bump for patheticness

It looks like the nonhomogenious heat equation, so it's amenable to separation. Enjoy.
>>7957300
Dubs have spoken.
Unrelated, but what (non-numerical) methods are used besides separation? I've yet to see them.
>haha anon actually reads textbooks relating to our major!
>hahahahahaha wow I think he's the only our entire undergrad who does that!
This happened the other day. I'm in my last year of undergrad.
Please tell me this isn't normal

Who cares what those future McDonald's employees say?
>>7957154
It might depend on what the major is. I'm just trying to think why someone would say that.

To be honest they're more likely to get hired than I am
They are women who actually have connections to people industry. I'm an unlikable sperg who is actually competent and has a decent GPA.
Why is high school math such bullshit /sci/? 90% of what you learn in high school you learn in Analysis I in the first semester of Uni - rigorously.
Why even bother? You don't really need it to study maths, and it's much less efficient than studying maths. They should abolish maths in high schools, or do it rigorously. The way it is now it's just a time-consuming clusterfuck that gives maths-interested people all the wrong impressions.
Why is high school foreign language such bullshit /sci/? 90% of what you learn in high school you learn in Liberal Arts I in the first semester of Uni - rigorously.
Why even bother? You don't really need it to study foreign languages, and it's much less efficient than studying foreign languages.

>>7957131
heh, almost
But the foreign language stuff you learn in high school won't become obsolete in Uni. In maths it does.
>>7957141
No it doesn't.
I need a best first Intro into textbook for every topic you guys have expertise in.
Pic related beautiful book

I'm still an undergrad so I don't specialize in anything but I've read through most of those and can vouch
What separates human intelligence from artificial intelligence? Isn't the brain just complex processes?
sexual reproduction
mortality
things like that
consciousness.
Then again, it could just be that I am the only actual living thing in the entire universe while the others are just complex systems that behave according to the laws of nature.
I think that it's the many mannerisms, tendencies, and outlooks we have developed as a species from evolution.
Artificial intelligence would have no reason to exhibit these traits.
If time travel was really possible, we would have already received tons of visitors from the future.
>>7956960
Not a good argument. They could just make their presence unknown or have gone to a time before they could make all of humanity be aware of their existence. Or they could be on separate time lines (universes) than our own.
The conclussion is based on no facts. As we have no idea how or IF time-travel works. Any conclussion is in itself fallacious
Any.
What if they don't want to come back to this time?
so /sci/ how can brainstem dead person wake up?
How can somebody wake up from clinical death ?
death isn't a switch it's a process
>>7956950
Or a gunshot to the head.

How dangerous are xenoestrogens really?
Should I - as a male - avoid them? If so, how? What can they do to my body?
>>7956901
>What can they do to my body?
Change the frequency and intensity of your period.

who is this semen demon ?

I would hope you're always avoiding xenos

How do I study Physics, /sci/? I'm a mechanical engineering student and I am very interested in being as good as Physics as I possibly can. I'm willing to dedicate as much time as possible to it.
Give me everything you've got, be it study tips, textbooks, online resources, encouragement, etc.
Learn math first so that you do not have any roadblocks

>How do I study Physics
The same way you study everything else, you read and do problems until you understand it. Also picking the right place to start is very important, for example stating classical mechanics with Goldstein would be stupid, start at the bottom (Gregory is good classical mechanics text). I know it sounds obvious, but I tripped up here when I tried teaching myself group theory. Also >>7956746 is partly right, a get a good mathematical methods book and you won't go far wrong, I'd recommend Riley et al.

He got the best grades for maths and physics.
He did average at languages.

I have a great idea for a kids toy that people have already been stealing from me in concept, because i talked about it online and faggots think they have a clever design when mine will blow everything out of the water.
Ppl are pathetic.
I need to patent my shit now before these shit eating inferior boys who suck at physics beat me to it
Ask Einstein
>>7956507
he said invention
Google how to file a patent dude.
Goddam my college education wasn't the the greatest, but one engineering design class had all the students file a patent (school paid for it) even if it was rejected. We need more practical education like that.
You're going to need some serious specifics OP, and cover all your alternative designs. You can't be vague. Like if you had metal as a material in mind, still say metal, wood, or plastic.

>he struggled with trigonometry
I struggled with pretty much every math subject when I was a kid, probably because I never paid attention in class or opened a book at home.
I was 14 at the time and had little respect for math. Then when I tried teaching myself basic calc I stuff whilst in precalc, I realised how awesome the subject was and figured out that I only hated math because lower-level shit was boring repetitive crap.
