Agreed. Also, there are not "two ways to teach quantum mechanics". For example, take the hugely popular book of Griffiths: if I remember correctly, equation 1.

Agreed. Also, there are not "two ways to teach quantum mechanics". For example, take the hugely popular book of Griffiths: if I remember correctly, equation 1.1 is just the time-dependent Schrodinger equation. From what I have seen, most teachers do not spend too long on the history of quantum mechanics but they do focus more on the physics of quantum mechanics that this introduction does. The difference is important, and completely ignored in the first paragraph of the linked article.
