I will make this clear, Classic Physics. Newton.

Everything else is banned until you complete Existentialism in Philosophy alongside Logic and Math. If you can ground your Reality with Logic and Math and Classic Physics, then you have no business touched any Physics beyond Newton.

I strongly recommend this book. 

Basic Physics ISBN : 978-1-11962990-0

Metaphysics must be explored with a firm handle on Classic Physics.

If you can’t help yourself, Tesla. ONLY Tesla. 

Mechanical Physics is not allowed at this stage.

Quantum Physics is strictly banned.
