I'm still in high school. I'm reading about physics as a hobby.(adsbygoogle = window.adsbygoogle || []).push({});

In this document the limitations of the particle and wave viewpoints are described.

I've read that the probability of an event is the squared absolute value of the probability amplitude. Why would you do that? Wouldn't just taking the square work as well?

On the first page of that document there is this probability amplitude: e[itex]^{i(ωt-k \bullet r)}[/itex]

Why iskrsubstracted fromωt? Why aren't the phases added to eachother?

It also says that the squared absolute value of this amplitude is constant but aren'ttandrvariables? Why would it be constant?
