Should I post some porn to get answers, or is 4chan really filled with stoned 14 yo neo-nazis?

These are all meme questions.
Never heard about the first question but black holes don't have a net charge. And the biological qm shit was a bad paper published by washed up scientists.

>>8537934
1. But neutrino oscillation is a real thing innit?
2. Black holes dont have charge? Explain this: you feed a black hole a loads of electrons, and after you wait for it radiate all its mass via Hawking radiation. Will the charge be conserved? If not WTF. If yes, what ensures, that the radiated particles have more negative charge than positive?
3. Yeah, it sounds like bullshit, just wanted to be sure.

smart enough to not do your homework for you

is that g/4?

it's not homework, i will reveal the answer in 5 minutes

i got accepted after doing my math undergrad in canada but didnt go

>>8537445
Why? Where did you go instead?

3rd year undergrad at cambridge this year, I know a few part iii students.
As far as I know any degree that's sufficiently mathematical is good.
I'm not planning to do a masters (not a good enough student to get the first/high 2i to get in) but the website is usally very detailed.

>The minimum entry requirement for non-Cambridge graduates is normally a UK first class honours degree in mathematics, physics, engineering, or statistics, or an equivalent qualification
Info on funding is there too.

About 4 oxygen atoms buddy

They are the same thing, though technically the acid is the compound dissolved in water.

>hydrosulfuric
nigga you're confusing hydrogen sulfide H2S and sulfuric acid H2SO4
no such thing as "hydrosulfuric"

i accidentally got 3M sodium hydroxide solution on my arm, was able to wash it off pretty quickly tho.

>>8536454
A lab partner at uni accidentally poured p-nitrophenol on my arm (at least thats what I think it was) during the cleaning process. Now I have a scar because I though it was just water

>>8536459
>accidentally poured
>accidentally

No one accidently pours anything, especially down someones arm.

You were bullied and this was an assault straight and simple. Report that troglodyte to the police.

If only these were actually the most prized degrees

OP, give me a convincing argument as to why Art deserves to be lumped in with STEM? My high school changed the STEM program to STEAM after my graduating class and I think it's a joke.

code monkey = just start with any language
computer scientist = that book and any language

>>8533784
Lisp is the patrician language par excellence.
C++ is retarded gobbledygook made to satisfy the needs of dumb computer architectures.
Choose wisely.

>>8533794
Lisp is a meme.

It's overly complicated and needs way more assumptions to work than Copenhagen (which really is not as unintuitive as people claim). The problem is that people seem to be clinging to the idea that particles are tiny things flying around, bouncing off each other etc. They are not, period. It's all about fields and once you got that, the whole discussion will seem ridiculous to you.

In the end all I see in the pilot wave bullshit is forcing a belief about physics into a theory. It's like when Aristotle proposed his geocentric model: The idea that the earth is indeed not the center of the universe seemed so inconvenient, that he did some insane mental gymnastics to make sense of a geocentric universe. It's literally just a coordinate transformation. It works for what it is, but the model was opaque regarding the fundamental mechanics at work, gravity.

So what I see in the pilot wave stuff is that an aspect of the apparent weirdness of quantum mechanics is taken and moved into a new, much more complicated and much less intuitive part of quantum mechanics. Mind, not because there is new physics hidden somewhere, but for convenience's sake. Of course you can formulate quantum mechanics in a million different, equivalent ways, but sometimes you should just realize when your approach doesn't really add anything, but keeping a few old ideas intact that are not really helpful in retrospect.

>It's overly complicated

No it isn't.

>needs way more assumptions to work than Copenhagen

That particles exist and their momentum is exactly the momentum of the wave function at their location?

>>8538264
>No it isn't.
Yes it is. You need to introduce a lot of shit into the system without any apparent reason to make it work. Copenhagen is straight-forward on the other hard. In the context of QFTs is perfectly clear what happens. Pilot waves in the context of QFTs then again are absolutely ridiculous.

>That particles exist and their momentum is exactly the momentum of the wave function at their location?
The question here really is, why do you need those assumptions? Really, why? If you knew what those quantities are in quantum mechanics, then you wouldn't even bother about it at all.

So what's the solution?

first the EM drive now this
2016 is just not the physicist year

Interesting if true. Now to see if it holds up to scrutiny

It's a big mountain.

Oxygen deprivation would probably make it impossible to ascend beyond a certain point.

kys nerd

>>8537902
yeah it's annoying but don't let it distract you, just put in some headphones with white noise and get down to work

fuck em'

>>8537902
take a step back and really fucking appreciate how pathetic you are

it's SHOCKING

ravioli ravioli whats in the pocketoli

What're u studying?

>>8537791
teach math I guess

>>8537791
Nothing you want, 300k student debt starting

>>8537791
You can invent new math now that you know where the boundariesof our current framework are. (kinda)

New math is by definition unimaginable, until it is imagined.

>>8537548
Kek. Why would you do this? Nobody will every hire a physics major over an engineer

>>8537550
DELET THIS HOMOGAY

>>8537554
I switched out of physics when I realize this. Not in eng tho

>>8537444
Newtonian mechanics doesn't predict orbits accurately enough.

Classical mechanics fails to predict motion of light and black body radiation.

>>8537449
Ah, so this was it. Thanks. Is there other stuff too?

>>8537449
That doesn't mean that the math behind it is wrong, it just doesn't describe physics correctly.
