I stopped caring about math when I was introduced to the concept of imaginary numbers. What a crock of shit. If your equation can only be solved by inventing numbers that can't exist, like some kind of math deity , then you are fucking wrong and the math is flawed. Same for algebra solutions that basically say "the correct answer is whatever the correct answer is". Thats what the math said transcribed to words but god forbid if i wrote in down in english instead of the ancient math runes the teacher word mark me wrong.

Math is logical and numbers never lie my ass. Math is just as flawed as any other human construct.

I realized imaginary numbers were real when working on precession. a 2D number plane is the only way to explain it. You see precession is all about addition of angular momentum causing a rotation. How can you add something to get a rotation on a 1 dimensional number line? There must be a second dimension orthogonal to it that it goes through in order to end up rotated.

Oh man, I guess Electrical Engineering is bullshit then, wonder how all those electronics ended up working when designed if imaginary numbers are a crock.

>>

>>7846911

It's an engineering, therefore it's bullshit.

nice meemee

In retrospect, maybe labeling them as "imaginary" was a bad idea. It seems to confuse the plebs.

>>

>>7846911

you can do phasors with vectors, making them complex is simply formalizing them as a value on the number plane.

>>

>>7846927

95% sure the name imaginary was given to them by some guy who wrote a paper shit talking the concept but it stuck. It is a very very bad name. You are correct.

>>

>>7846944

What's worse is the "imaginary" unit is denoted as i. I'm pretty sure it was also formalized by an electrical engineer to, just to make it worse.

engineers actually use the symbol j

Math is about ideas, fuck numbers.

>>7846988

This, I don't even think of complex numbers as numbers. They're the subalgebra of linear operators R^2 to R^2 generated by dialations and rotations, or R[X]/(X^2 + 1) if you want to be fancy.

>>

>>7847017

But are they imaginary dilations and rotations?

>>

>>7847034

No, that's the point. If you believe in the plane and you believe that you can move points on the plane around you should believe in complex numbers.

>>

>>7847039

I was just joking. You're preaching to the choir.

I stopped caring about physics when I was introduced to the concept of Calculus. What a crock of shit. If your equation can only be solved by inventing fields of math that can't get you laid, like some kind of math autist , then you are fucking wrong and the physics is flawed. Same for math solutions that basically say "the correct answer is whatever actually follows the directions". Thats what the physics said transcribed to words but god forbid if i wrote in down incorrectly instead of the ancient math runes the teacher word mark me wrong.

Physics is logical and numbers never lie my ass. Physics is just as flawed as any other human construct.

I stopped caring about everything when I was introduced to the concept of life. What a crock of shit. If your happiness can only be solved by inventing friends that can't exist, like some kind of chad , then you are fucking successful and the life is great. Same for life solutions that basically say "it gets better".

Life is fun and every day is a gift my ass. Life is just as flawed as any other human construct.

i stopped caring about maths when my maths teacher molested me.

Solutions in the complex plane always contain the reals. Therefor complex numbers are always a valid extension to physical problems.

Its for people who like dank memes, but they've done too much STEM to appreciate any other board.

>>

Math is a fucking hoax. How can Real numbers be uncountable if Rationals are countable?

Between every real there is always a rational, and between every rational there is always a real. So they have the same cardinality.

Math is complete bulshit

I stopped caring about physics when i was introduced to Quantum Mechanics, what a sack of shit, i'm too stupid to find the position of subatomic particles, so i just assume that they can't be found.

I can make up "imaginary" number too. Doesn't make them real.

Best case of meme mutation ever seen, from internet-tier meme to fine-art.

Zero isn't a natural number. Sqrt(2) and PI aren't either. Math is a language we use to describe things in a useful way and it changes over time because we learn more about what we want to represent.

>>

>>7846556

I wish people would stop thinking of imaginary numbers as numbers. They make significantly more sense when thought of as matrices. Also, I wish that educators would stress that there are literally infinite number systems like complex numbers and that extending the real numbers isn't unusual. Also, I wish they would stress that math is only a system of tools and and numbers don't actually exist (some may disagree).

Actually it was formalized by Euler.

>>7846556

Aside from being useful for solving electrical circuits, they are also useful in complex analysis.

You can solve REAL variable integrals by using the residue theorem. Why would you use complex-variable integrals to solve real ones? because sometimes solving real integrals is reaaally fucking hard, even if you have wolfram alpha.

>inb4 real integrals are also useless
