it's a triangle in [math]\mathbb{R}^2[/math] where the Euclidean dot product is replaced by the form [math]\langle u,v \rangle = u_1v_1 - u_2v_2[/math]. there's nothing wrong with the picture.

Of course it's a random analogy. No different than me calling a Euclidean square a Euclidean pseudo-triangle, which is what I meant to write. Who cares? What are you trying to say with your imperfect analogy?

all physicists care. the geometry where a vector's length can square to a negative number is the basis for theory of relativity. Pythagorean theorem holds here as well, and it takes one glance at the proof to understand that the analogy is anything but random.

Which, again, has nothing to do with the fact that pseudo-Euclidean space is a generalization of Euclidean space, not the other way around. Someone says "that's not a triangle" and your reply is "yes, it's a generalized triangle." I'll ask again, do you have a point?

This guy gets it.

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.

not only that but you invent new special exceptions and rules that state
>my ultimate based&redpilled theorem applies everywhere... except for the case where it's an imaginary number. Then that's bad and you should cease applying it asap.
Which in that case is the meme imaginary triangle. It's a simple statement, it just adds an i-length side to a unit triangle. Everyone above age 14 is aware that you can't do that, yet everyone is also aware that math isn't supposed to be this easily breakable and to have to rely on some exceptions to prevent you from doing this. A whole set of numbers for what exactly? You can't even apply them anywhere. And the other perfect example is the division by zero which breaks math before you even begin to move the number line.

From this point onward you can attack the entire ZFC and the claim that there can exist infinite sets, a claim that is reflexively taken as the ultimate Truth in modern society, which is false because the only ones geometrically applicable to our reality are the natural numbers. Everything else is judeo-rationalist cope, an attempt to pull you into the platonic realm of infinite possibilities that does not respond to the reality that is limited from these infinities.

There are integer polynomials whose roots cannot be found in the integers. In order to solve these equations you have to make up these new numbers called rational numbers. Similarly, there are equations made from rational numbers that cannot be solved with the rational numbers so we invent another fictional new type of number called irrational numbers (wtf!). The irrational numbers combined with the rationals forms the set of real numbers. The imaginary numbers also are created to solve real cooefficient polynomials not solvable with real numbers numbers. All imaginary polynomials have roots in the set of imaginary numbers (which reals are a subset of). By your logic of imaginary numbers being made up, so are every other number other than the counting numbers (ie natural numbers). Fractions don't exist and are fictional nonsense.

Before non-integer multiplication the concept of 5.4 times 7.8 didn't exist. Suddenly, when multiplication is generalized to non-integers this becomes feasible. No difference with "imaginary numbers", you're just bitching about the name.
