With cosmology driving physics as practiced in our major universities to being more esoteric and bordering on fantasy, prompted a look at the foundations of quantum mechanics. There were strong historical and cultural forces driving the subject into this dead end. A series of unfortunate mistakes were found in quantum mechanics from the 1930s that had more to do with vanity and pride than anything in physics. The misgivings about the subject of quantum mechanics expressed by Einstein, Dirac, Ehrenfest and Feynmann hinged on the disconnect between relativity and quantum mechanics. A solution to this problem is worked out in detail as a self-study course in the book: "The Principles of Matter, amending quantum mechanics" which connects the microscopic definitions of matter to the large scale.
Quantum mechanics is just not the mechanics of the small. That assumption was a mistake made early in the 20th century and was never corrected. There were a series of other mistakes coupled with poor assumptions that reduced the utility of quantum mechanics. Correcting those errors and integrating relativity into the subject clears away much of the confusion that permeates the field. Cosmology looks very different when its quantum basis is corrected.
