>>11988021you clearly never worked with second-order linear differential equations, which are essential in physics and in wave equation in particular. Using saves you so much trouble when integrating/differentiation/doing algebra on it than sine and cosine.
>Made up bullshitcongrats, bro, so are all other numbers. One way to rigorously define natural numbers is through fucking empty sets.
https://en.wikipedia.org/wiki/Set-theoretic_definition_of_natural_numbersWhy aren't you flipping out on that, but complex numbers are a problem. Ah, let me guess, it's the word "imaginary". Are rational numbers actually rational? It's just stupid semantics.
>Exactly what does the imaginary unit mean?It is an element of the set with the property . Now you can define this set using the algebraic definition in

>What does I in the Schrodinger equation mean physically?what does force mean physically, you genius? Can you feel it? You feel acceleration, but that's it. The concept of force is completely useless in non-classical physics and even in some classical situations it is much more desirable to talk about energy and momentum, which are even more abstract than force.
