Weird or unusual images in your brain help remembering complicated stuff.

As if a hair covered ball isn't weird enough.
>>8902489
Doggos are cuter than balls though. Also note that the common german name for the hairy ball theorem is "Satz vom Igel", which could be translated to "hedgehog theorem". If you try to comb an hedgehog, you will always get a bald spot.

Physics can't either.
Here's a fun one, if mathematics can't do it, neither can physics, since physics is literally just applied mathematics. No, you playing with legos is not physics, you autistic mouthbreather.

When an author does that he is basically saying: Here, my child. I have trained you well. I know trust you in being able to alone re-discover one of the important theorems in mathematical history so that you too can feel like the mathematician you will one day be.
When an author does that you should put your hand on your heart and sign the national anthem while crying as you can feel the author giving you the trust, space and respect your dad never gave you.
Wait, I mean my dad. Hopefully your dad also didn't love you.

What is keeping you away from getting a rigorous mathematical education? The only way you can become good at spotting problems in a proof is by getting shit at by a 60 year old professor who has been writing proofs for more than 4 decades and now expects you to in the few weeks he has been giving you the material to learn to write as rigorously as him.

>But where did the frog — Dat Boi himself — originate? Not in AP Physics 1 Essentials, its author, Dan Fullerton, told me over the phone: “I was working on a problem about rotation. I thought the art was interesting, and so I made the problem about that.” Fullerton, who teaches high school physics, said he would ask his students about Dat Boi.

Not everything in math will tell you the behavior of things in the real world. Say if you graph a sine wave, it will model the amplitude motion of the wave and other properties, but it still won't tell you things like what kind of a wave it is. The wave could be longitudinal or it could be transverse, and math wouldn't tell you that. There's a reason that they're separate disciplines. Math uses symbols to represent the logic and patterns behind everything but physics deals with the world directly. Physics isn't just applied math. It uses math to prove ideas and express things but it's a lot more than that

Physics is basically a pairing of observable quantities with symbols in equations. It will tell you what type of wave it is if you wrote down field equations for example.
Not /sci/ related but anyways

He is citing both a famous Calculus textbook and some foreign book on basic algebra and geometry. Obviously one is much more advanced than the other.

PDEs are a profitable application of differential geometry. Finance makes use of them and often hires mathematicians for this purpose. Hence sponsors.

Because there isn't on the campus from my city.
It isn't federal or particular, it's the state university of Santa Catarina.
It does have Computer Science but I belive only in the city of Joinvile.
I went to Florianopolis to study at UFSC before and I got into a major depression unable to adapt to the life in a 'big' city. So since I feel unable to go to Florianopolis I think I also wouldn't be able to go to Joinvile.
(and for the record, the math teachers that I had at UFSC weren't that great either.)
