The “elegance” of math and physics is something they go on and on about. Anyone that’s ever done actual engineering or science knows this isn’t true at all, most empirical models for things have horribly messy equations and coefficients that make the equation horrible to work with. Fuck anyone that likes science or its supposed “elegance”.

Elegance is when you "prove" dark matter by having wrong equation and wrong coefficient in it.

I've seen discussion of this equation online when I was just taking trigonometry course.

>>10857557
Actual math is generally quite pleasant. The beauty comes from the grand systems that are constructed based purely on some axioms and rigorous logic, though, not because of numbers. But in that respect it's basically just philosophy. Physics and engineering are genuinely ugly as fuck most of the time and are so impossibly hard to describe analytically that most of the time it's easier to do hundreds of experiments and use an empirical model, or the analytical model is generally off by at least a factor of 2 so you have to do experiments anyways to correct the model with empirical coefficients.

Engineers more often use semi-empirics, averaging and approximations, while mathematitians and physicians look for general, closed expressions.

Just a simple example: take a bowl of milk. The task is to find the time it takes for milk to spill over given a constant rate of milkflow per second Q and a given amount of bowl volume V.

The scientist's approach is to find a close and simple expression lile t = V/Q, such as given a flow Q of 0.1 L/s and a volume of 1 L, it takes 10 seconds to fill the bowl. Simple and easy.

The engineers approach is different.
What if the shape is such that the flow always spills due to the angle of attack? What if internal turbulences cause it to spill earlier? What if the bowl has internal standing waves whose crests spill over? Sooner than later, you have navier-stoke equations and perform a messy FEM simulation, derive multidimensional graphs and investigate every case the milk spills sooner than you think.

Not the best example but conveys the idea.

No engineer would do this. We take 1 class on fluid mechanics and most of it is dedicated to pipe flow. We would just use V = Q*t

Only if you're an undergrad doing problem set for homework. Let's change the scenario. The problem stays the same, but this time you have half a million dollar worth of catalyst in oil refining chamber. Same analogy with the milk. Would t = V/Q suffice or would your higher up made you model the shear along the refining chambers and pipes?

Yeah, it's basically toted by the same type of people who find complex numbers "mysterious" and "mystic". There's just way cooler shit out there, even if you want to restrict to instances of exp(i ••• ). E.g. harmonic analysis, Stone's theorem for one-parameter unitary groups, half of Lie theory, etc.
Not that I'm enough of an autist to get a shirt with an equation on it, but if I had to, and it had to use exp, I'd rock the double cover of SO(3) by SU(2): [eqn] \mathrm{SO}(3) = e^{i \mathfrak{su}(2)} / \mathbb{Z}_2. [/eqn] Now that's a fun one.
