>What are fields?
rings where every non-zero element is invertible

>Why are there fields?
because certain sets fit the definition

>>8826943
Fields are just a construct. You cant know nothing about fields.

>>8826943
Wow. I am a brainlet. Thanks.

wow, an integral. very science.

But to be serious, I probably wouldn't understand an article on art history either.

It's a science and its object is the crazy speculations of maniac stock market speculators masturbating to charts and all trying to tell the future at the same time resulting in everything collapsing and destroying itself.

So yes it's a science and it's quite close to psychology.

Some situations in micro economics need next level maths
Macroeconomics always needs statistics

>>8826702
I agree.

>he doesn't read Neo-Kantian epistemology and existential phenomenology at the same time

>>8826702
So psychology is a science?

>>8826702
The wave function is real and there's nothing you can do about it

>>8826665
Not a science sry.

Butane is a bastard gas, I tell ya hwhat. Anyone who prefers it to natural, clean-burning propane is a degenerate.

It means you should let epsilon be less than zero.

>>8826471
>What does this t-shirt mean?
It literally means let epsilon be smaller than 0 but then that is an analysis joke because 99.9% of analysis proofs, at least the beginner level, start with in some form or another letting epsilon be an arbitrary number larger than 0.

>which PBS studio host's butt hole would you most want to lick?

None because I am not a fucking sexist so I don't sexualize science and math show hosts like you fucking degenerate.

>>8826491
Thank you.

I'm an equal opportunity butt hole licker. I'd like Mike Rugnetta's butt hole for example.

You fascist.

I once had a dream where I was chilling in a bar with Hamilton, Euler and Russel. We got super shitfaced and started coming up with a universal mathematics, written on bar napkins.
I can't remember any details about the math itself. But I remember it didn't contain any symbols used in common parlance.
Just as we were finishing up a proof of the Continuum Hypothesis, Kurt Godel busts in and starts shooting up the place with a machine gun. Then he doused the floor with gasoline and lit it on fire, and calmly walked out, muttering something about Leibniz.

The fuck, I can't even dream about axiom systems let alone recognize them in my dreams
Did you get spooked by pic related or something

Don't do this, OP. Get psychiatric help instead of asking 4chan how to kill yourself.

essentially all of mathematics is the study of functions

or sets, depending on how you ask, because functions can be defined as sets

>>8826001
If you're underage and just learning functions, the answer is yes, functions are used everywhere. They never really disappear, and when they do, it's only because we are using more sophisticated terms to replace them

Almost all of mathematics involves looking at structures and functions between those structures: topology and homeomorphisms, analysis and continuous functions, differential geometry and diffeomorphisms, algebra and homomorphisms, category theory and functors, sets and in/sur/b-ijections, etc.

Things that hit the atmosphere at 30km/s get destroyed by it. Slow stuff only needs to worry about hitting the ground.

It just sits there, doesn't move at all, there is no friction to generate heat. A station on the space uses centripetal force to keep the cable tight. An elevator climes up and down that cable.

>>8825934
Reminder: it only takes 10% of the rocket fuel to reach the altitude of orbit. The other 90% of the rocket fuel is used to move really really fast laterally, parallel to the ground. Being in orbit is not just being high; it's also moving really really fast. Google Newton's explanation of orbit of a sufficiently fast cannon ball.

When things come back down from orbit, most of the damage from the atmosphere is because of that lateral motion. You could survive a fall from the altitude of satellites, if you also happened to not be in orbit, e.g. relatively stationary compared to the ground beneath you, plus an oxygen tank (approx).

Khan did nothing wrong.

now that you point it out, he kinda does hahahaha

Do 20 or mote tedious examples and you will probably wobt forget the most basic ones. Many can be derived by either pure chain rule + other rules and trig identities. There's really no need to memorize them with a table except you are a legit brainlet.

this is all you need to memorize, you brainlet fuck.

>>8825305
After Calc 1 I was allowed to just bring a flash card with derivatives.

Now, after Calc 2, I was allowed to bring a flash card with integrals.
If your university isn't shit they should allow the same.

>I understand the concepts behind this math, so, is there a point in memorizing them for just one or two tests?

There really is no point for forcing yourself to memorize derivatives but if you truly understand the material you will eventually memorize them without realizing it. For me, every time I have to remake my flash cards (I am a messy person and they get damaged or lost) I find that there are less and less identities I feel like I should put. I read a complete table of derivatives/integrals and like 90% are of the kind that I know I could derive in less than half a second. Now I buy the extra small flash card paper because I don't need that much when in the past I used jumbo sized flashcards.

It's very well regarded don't write it off just because it's not a campus university.

It's also now FAR cheaper than a campus uni. But obviously you're not going to get the social aspect of attending a real university and if you're a teenage autist like everyone else on /sci/ I really can't stress how important that is.

It's perfectly possible to study for example Maths at the Open Uni and then do a postgrad at Imperial or Cambridge but I'm not sure how Physics works because of the lab requirements, I believe the OU has lab centres you attend in person.

>>8826171
that's great news, thanks anon. I would much rather attend a brick and mortar university, but the issue is I didn't take mathematics at a high enough level at highschool. I've been accepted to a bunch of physics courses, but the one I accepted isn't willing to let me study math alongside because of this. Very frustrating.

>>8826401
>physics courses
meant to say chemistry courses.

Same reason we find visual art appealing or culinary arts tasty. Like all the other animals, we evolved to find some things pleasing for survival reasons.

Good thread. I've always wondered, is there such thing as scientifically created music? In other words, music that has been created using scientific evidence to be appealing to us?

The frequencies of harmonics are evenly divisible, by the note frequency.
You have all these evenly divisible frequencies together as a group, and the result is a note, rather than noise.
I'm just speculating here, but it probably is less straining for an ear to pick up frequencies that are harmonic than just scattered noise. I think the ear itself gets less physical strain from registering notes than it gets from registering noise. I don't think the preference is an intellectual one, or one that needs any processing by the brain, rather a physical one in the ear itself.
