You might think that in every real world application, complex numbers are introduced as a convenience, and that every calculation that takes advantage of them ends with taking the real part of the result, but that's not the case. In QM, the final answer contains an imaginary part that cannot be removed.
- BeetleB 3y agoHaving studied QM, I disagree. You can always introduce trigonometry and remove it. Keep in mind that everything observable is a real number even if the intermediate calculations involve imaginary numbers.
- tome 3y agoYup, and the Madelung equations explicitly present QM without complex numbers: https://en.wikipedia.org/wiki/Madelung_equations#Equations https://en.wikipedia.org/wiki/Madelung_equations#Equations
