Hello fellow high IQ users of this website.

I'd like to learn about physics, and khan Academy seems the most straightforward place to get my bearings on the laws of motion and heat exchange and all that jazz.

Does /sci/ recommend this, or is there elsewhere a better starting point?

I dont know, fags around here will probably recommend you some book.

You like em text books?

>>8578208
I've found even basic textbooks will quickly expect me to know a little more than I do.

Khan Academy is alright, but I'd recommend a text book if your looking to teach yourself. On the /sci/ wiki you can find some textbook recommendations. Make sure you have the required math knowledge.

Can you actually make decent money studtying physics/math (evevn applied), or would you be better off with Medicine?

(Given u wouldn't have to pay anything for your studies.)

You can make decent money, definitely, but it doesn't come even close to what you can do with medicine. And I say this from the
perspective of someone studying mathematics.

In STEM you are succesful if you earn 100k a year. You are very fucking succesful, actually. Meanwhile in medicine earning 100k would be considered terribly unsuccesful and means you are either working part time because no one wants to hire you, or you chose the shittiest especialization.

If you care only about money then pick medicine but always remember: When it comes to university degrees, everything you gain in terms of money is traded by bits and pieces of your will to live.

That went dark. I have a friend doing radiation physics. He seems to like it a lot. I thought about doing that, but instead I went to "ordinary" physics graduate school.

One of my professors in undergrad never got married and lives in a one bedroom condo close to the school. I once made a remark about how many books he buys in a week and how big his personal library is. He responded by telling me that he doesn't know what to do with all of the money he has saved up. I'm sure his salary isn't terribly impressive, but he's super happy with his job and doesn't have to worry about money at all. The point is that the amount of money you make shouldn't be your only consideration. If you love physics or math, you should strongly consider doing physics or math. Plus, as shitty as it is to the university, you can always drop out and get a good job with a physics or math bachelor's degree (at least your chances are pretty good as far as majors go). IT takes a while to get paid a decent wage. I'm a grad student now and I get paid more than enough to live on and based on the amount of work I actually do, I feel like I'm robbing the place. But it's going to be a long time before I make a respectable wage.
>>
>>8578108
>That went dark.
But its true.

The people with the most will to live are those who study liberal arts. They either get super pumped to do easy peasy art with no actual labor, or they get so brainwashed by some political ideology that they can't wait to start their activism. But they are all poor.

Then there are tech degrees. Easy degrees that give you the necessary degrees. Still, you have to put effort and you are not so happy go lucky but it is still good. Your wages are still low

Then there are STEM degrees that put you all over the place, but solidly at or above the middle class. But the constant hard work can take some of your carelessness and turn you into a serious human being.

Then there are the top MONEY MONEY degrees like medicine and law that have soul crushing competition, soul crushing courses, soul crushing requirements and soul crushing end results. You end with your soul empty but your pocket full.

The problem doesn't specify if leftover dust adds on and hits people after they clean out their first bout of irritation, or if this is dust which just goes up and goes down, only affecting the local area for at most the amount of time it takes all the dust to get back down to the ground.
Since the second is more logical, I let it hit the dust demon and everyone in the area just wipes their eyes for a few minutes and it's over with.

In differential equations you start with differentials so pretty much it is all integration.

I just took DE this past semester. First half of the class was mostly integration, second half was mostly linear algebra. I don't know though, it also depends on your professor. As a side note, I understood differential equations way more than I understood linear algebra.

okay so a person I talk with counters literally any possible argument with what boils down to "well quantum mechanics disproves causality so you're wrong" (no, none of those arguments started as anything related to quantum mechanics)

I very much doubt that's true but I don't understand quantum mechanics and looking it up in wikipedia has made me understand it is too complicated to learn by skimming a wikipedia article. please summarize this for me, how crazy is quantum mechanics?

It isn't true
The person you talk to is what is known as a pseudo-intellectual pretentious brainlet
It is the equivalent of saying something like

Some things start a lot of debate and cause a lot of confusion. There are also a lot of interpretations which are different. A lot of people just don't like it--nature being inherently probabilistic gives people the wiggins. Moreso than other courses, when you first learn it, you kind of have to just roll with it. You learn to DO quantum mechanics first. All this to say that you don't have to like it and you don't have to understand it on a deep level. You just have to accept that it is powerful and here to stay.

Alternatively you could smash his head with a hammer and say "since there is no causality, I couldn't have possibly harmed you"

Editing genes to eliminate cancer or Schizophrenia could stop the rise of geniuses, scientist warns

Advances in genetics could one day eliminate diseases like cancer — but might also wipe out geniuses like Stephen Hawking from our future, warns one scientist.

Dr. James Kozubek says altering human genes to erase depression or Schizophrenia, for example, could stop the rise of the next Shakespeare or Einstein — as creativity and high intelligence are often associated with such disorders.

Writers are 10 times more likely to have Bipolar Disorder. Poets are diagnosed with it 40 times more often than the general population.

Anyone here study biology?

How do biobros generally view these ROGUE NEO-LAMARCKIAN, KNOWN EPIGENETICIST! types?

I study the Philosophy of Science (lol) and while I can just read the intellectual history of the theories and whatnot, I'm interested in how the "normal science" works within the discipline itself.

Your knowledge has nothing to do with the 2/3 chance. The part matters is the conscious removal of a goat.

But still, the problem has changed from a 2/3 chance to a 1/2 chance. You can't just move the probability wherever.

I am asking if it is possible out of curiosity if our modern society can exist without using animal products.
>>
>>8577905
If everybody goes vegan then say goobye to the meat industry (worth billions) and while that means some billioanaires will be driven to ruin (which is good), that would also imply that the millions of middle class and poor workers who do labor for this industry would get absolute fucked, which is terrible. Then they would have to get a job in the new "plant industry" but then that would imply getting new skills they don't have and more competition, given that big plants don't need as much care as big animals.

If the change is slow then probably. The meat industry would be having to decrease production and therefore employment year by year slowly so the workers would have enough time to research their field and find a job without losing too much time, preferably in the new plant industry.

>d-did you just bring class politics into a discussion of veganism?

Yes you fucking white upper middle class privileged scum.I know its cool to pretend not liking meat, shop at Whole Foods and pay for a single potato with 20 dollars to seem cool and hip with your other white hipster friends but the world is not like that, you fuckwit. Go kill yourself and take all the other retarded vegans with you.

Hey /sci/, I have a BS in math and am currently applying to graduate schools. A few of the schools to which I'm applying have sizable faculties studying mathematical logic/set theory/model theory/etc, and if I go to one of these schools I'd like to concentrate on that.

Unfortunately, since logic is relatively niche, I'm worried that I'd have a hard time finding a job. Many universities don't have a single faculty member that specializes in logic, so post-docs would be scarce. What sort of careers in industry could I pursue? Would it help if I focus on something with applications to theoretical computer science?

In industry? Your best bet is to tie whatever you're doing to some form of applied computer science. You'll also need to pick up some hard CS skills: you're not getting hired if you have no idea how to implement or apply what you come up with to a real-world system.

>you're not getting hired if you have no idea how to implement or apply what you come up with to a real-world system.
This is gonna sound like I'm memeing, but, shouldn't that be someone else's job? Why would you hire a PhD in mathematics to do coding? Or are you just telling me to get a CS degree?
>>
>>8577748
>Why would you hire a PhD in mathematics to do coding?
You're right, instead they'll hire neither of you.
