Einstein: Could he have been the father of QM?

In summary: QM are the formulas for stimulated emission, the germ of lasers and masers. Recently, I have realized how much did Einstein contribute, indirectly, to the field of QM. I mean, using his two famous relations E=mc^2 (relativity) and E=hf (photoelectric effect), we derived the relation p = \frac{h}{\lambda}. Then, by the help of a keen insight from de Broglie, we hypothesized that matter could also behave like a wave (i.e. wave-particle duality) whose wavelength can be given by the relation \lambda = \frac{h}{p}. This lead us (i.e. Schrodinger) to

karlisbad, I think the point you are missing is that anything that you truly understand is absurdly simple..

when first confronted with calculus it's a complete mystery, then when you learn it it's extremely easy.

same with anything, for example I'm learning QFT at the moment. Every new page seems to be written in greek :S :P (it's an extremely condensed treatment) but once I get past a line I think how very easy it is to get from A to B if you know how..

the difficulty in studying/researching physics is not how advanced or developed the physics is, but finding the road to understanding/solution when you have few or no maps/signposts..
