It is called the concordance book of Shakespeare. If you want to look up a saying by Shakespeare but forgot where it lies, you get out the concordance and find exactly where it was written. But in modern days, the Google search is a concordance of any AP writing. No need for a concordance of AP, just Google search.
But unfortunately search engines were not around in the 1960s to make a search of any saying to be found in Feynman's 3 volume Lectures on Physics. But never the less, many people have put Feynman books on the Internet. So I search for "amalgamation" with Feynman Lectures and up pops Volume 1 chapter 2.
2-2
"Some historic examples of amalgamation are the following. First, take heat and mechanics. When atoms are in motion, the more motion, the more heat the system contains, and so heat and all temperature effects can be represented by the laws of mechanics. Another tremendous amalgamation was the discovery of the relation between electricity, magnetism, and light, which were found to be different aspects of the same thing, which we call today the electromagnetic field. Another amalgamation is the unification of chemical phenomena, the various properties of various substances, and the behavior of atomic particles, which is in the quantum mechanics of chemistry."
"The question is, of course, is it going to be possible to amalgamate everything, and merely discover that this world represents different aspects of one thing?"
AP writes: The last sentence is answerable--- yes, the world in total is just one big atom of plutonium, a Plutonium Atom Totality.
But the question I have of Feynman is why on Earth does he use the term "amalgamation" when he could have used a logical term of "unification". He does mention "unification" in the above. Did Feynman think that unification is something different than amalgamation??? During the lifetime of Feynman, the Unification of the 4 Forces of Physics was never realized. Einstein spent 30 years of his life trying to unify the 4 forces and failed. Perhaps Feynman shyed away from using "unification" because the 4 forces had not been unified and he was embarrassed over this situation.
AP unified the 4 forces in early decade of 1990s by pointing out that the EM force is the only force with a "perfect particle", the photon and logically, thus, the conclusion is that strong-nuclear, weak-nuclear, gravity, had to be ------ different aspects-------- of the perfect force of EM. Feynman does mention "different aspects" above in his amalgamation. But then Feynman makes the mistake, another mistake of logic, when he talks about the Double Slit Experiment and pondering whether it is particle or wave or both, or neither. If instead of pondering the Double Slit Experiment as a mystery, Dr. Feynman needed to go back to his paragraph 2-2 and see that he wrote--- "different aspects of one thing". So that Feynman could have deduced that the Particle versus Wire-circuit are one and the same things only displaying one aspect at different times.
