Main Question or Discussion Point

I’m having a hard time, as I begin learning QM, knowing what it applies to, if I can put it that way.

Is QM the rules that describe how the particles of the Standard Model interact with each other? Or what is the best way to understand the relationship between what one studies when one studies QM and what one studies when one studies the standard model?

Quantum mechanics is necessary for understanding the Standard Model, but it's also possible to form many other theories in QM in addition to SM. This is similar to how Newton's first, second and third laws are necessary for understanding the classical theory of gravity, but can be applied to other things, too.

Our modern electronics, such as your microprocessor, your mobile devices, your computers, etc.. are all built on QM.

Modern medicine, such as MRI, are built on QM.

QM's applications are all around you. You do not have to reach out as far as the Standard Model or particle physics to find them.

Believe it or not classical mechanics is built on QM. But first you need to learn QM to the level of path integrals and Classical Mechanics at the level of a book like Landau - Mechanics.

Thanks
