Did you know that in an incompressible, potential, irrotational, inviscid flow we have it that a body will experience no drag force? It's true! Solve Euler's equations discover that fluid mechanics is literally made-up bullshit that doesn't describe reality.

Literally all theories are made up and don't describe reality 100%. A theory that describes reality well enough for 99.9999% of cases is pretty good.

What you want is a Theory of Everything. Come back in a few decades, we might have one for you then.

Thiz nigga gets it. If middle and high schools would properly teach this, there'd be fewer idiots saying ignorant shit like "Relativity means Newton was wrong".

A theory is a model that makes reliable predictions. Newtonian mechanics, for example, was reliable enough to put people on the moon. Special relativity is reliable enough to make GPS work as intended. The germ theory of disease is reliable enough to reduce, measurably and significantly, the proliferation of a disease.

Mere belief systems, such as astrology, homeopathy, and islam, make no reliably measurable predictions about how anything works. Assertions, that people simply want to be true, do not qualify as theories for this reason.

I was looking at pdes earlier and this topic came up. I ignored it cause I don't give a fuck if my math can be applied to reality. Physicists are the biggest cucks, they try to apply math to the real world without even realisng that math can't describe it and isn't valid in it lol
