While he may potentially be a wizard, it's also very likely that he sincerely enjoys his subject to the point where he studies and practices for leisure.

What did he do, if I may ask, that has made you feel so insignificant? John von Neumann's particular ability was his ability to quickly perform brute-force mental calculations and considerations. This would have given him a huge advantage since it would allow him to essentially increase the rate at which he can consider, accept, or reject ideas.

I'm 18 and I'm in senior level uni classes for mathematics (category theory and algebra. I've taken complex and real analysis, group theory, ordinary and partial Diffy Q's already.) Tbh I don't give a damn when someone isn't as proficient as me, so unless people are absolute dicks, I wouldn't worry about being looked down on or anything.
Also, for me, I just really like the subject so I'm highly motivated to learn more. I basically have no friends but just sit around and read math papers and textbooks in my spare time, or I program.

There's always someone better. That's life. Stop whining and grow up, you fucking man child. Think of it as a lesson in humility.

I see LED lights all the time, no idea if they are better or not visually

Numbers are a social construct

infinity is a number and zero is how many times you've had sex

>>7984849
zero is half an infinity
infinity is two zeroes

Using only that 1+1=2, what's 3+4?

>>7983421
In the everyday sense of "1+1=2," no, it cannot. For example, you cannot say that there exists an empty set from the above statement.
If you want to consider "1+1=2" in a more rigorous sense, then learn how to bait better and actually try to define it.

>>7983428
1+1=2
2+1=3
3+1=4
1+1+1+1+1+1=7

he means if they installed it on an elevator it would try and play pong with the skyscraper next to it

>>7980501
AlphaGo and its other cousins from the DeepMind team rely on being able to rerun the exact same scenario literally millions of times. If you try to do this IRL, it would take too long and also fail because past tries would influence the environment of future tries, leading to nonstationary data.

fuck what do i do? where's the middle ground?

>>7984451
Doing enough problems and getting some proper time invested will make you like the subject.

>no constants that are complex numbers

That's a strong statement, you have a way to prove that?

any math will help you do other math easier

that said, calculus is elementary. you only need to follow instructions. you might need to work harder and start trying to learn instead of memorizing

>>7983017
How the fuck did you fail Calc 1?
Discrete Math is completely unrelated to Calc 1. Taking it b4 Calc 1 won't help.

Discrete math is indeed easier, but if you're failing Calculus I, you need to try harder.
You're a computer engineering major. You'll need to learn it. It's not a fun class, and I only got a B in all three of them, but it's necessary.

I will say that after taking all three of them, the discrete math course at my school is a complete cakewalk. I've scored perfectly on almost every exam and quiz so far.

Search for "CalculusExpert" on YouTube, she explains it really well and makes it look as easy as it is.

Because you barely learn anything.

>>7978398
It depends, if you enter academia you'll quickly find your undergrad is pretty irrelevant, most people learn outside their field and end up doing something completely different.

Entering industry there are good and bad people in all fields who are paid well and shit respectively. The main reason to do enigneering is if you want to work in a specific industry requiring licensure; ie if you want to design and sign off on nuclear reactors you need a Nuclear engineering degree.

What's nice about engineering in general is that you can get a PE from it, a PE gives you a lot of leverage in wage negotions, especially in academia and research where people get fucked.

In general an engineering degree is more valuable for you unless you are absolutely sure about what you want to do, it gives you more freedom in general.

>>7978400
This is something that could be said about undergrad in general.

Yeah, still not seeing why they get shit on

Vectors aren't numbers, they are just represented by numbers.

Look at geometry, there are no numbers there, just we represent properties of shapes with numbers.

Knot theory also uses no numbers.

In answer to your question, it really depends on your definition of mathematics. Is geometry mathematics? Or is what we use to describe geometry mathematics?

If the answer is the latter, then maths must use numbers, if it's the former then certain branches of mathematics do not necessarily need numbers.

>>7973967
Yes. Just like ZFC but without the infinity axiom.
