QED: The Strange Theory of Light and Matter by Richard Feynman Book 30 of 2022


 
At the beginning of his third lecture/chapter in the book QED: The Strange Theory of Light and Matter, Richard Feynman says:
Most of the phenomena you are familiar involve the interaction of light and electrons--all of chemistry and biology for example.The only phenomena not covered by this theory (QED or Quantum ElectroDynamics) are phenomena of gravitation and nuclear phenomena; everything else is contained in this theory.
And QED is a theory because it predicts the behavior of light and electrons better than any other theory. That's how a conjecture becomes a Theory.
Everything about science is contingent. A new discovery submitted to rigorous testing can and will replace the previous understanding.

In his inimitable way, Feynman walks the reader through adding arrows of probability and showing how these probabilities are behind all of matter, everything we see and touch and all the processes that keep living beings alive.

The final chapter of the book is about nuclear physics--the particles inside atoms surrounded by clouds of electrons and photons that hold atoms together and give them their chemical character. And in one last paragraph, Feynman says gravity is something else entirely, vastly weaker the electromagnetic forces which are vastly weaker than nuclear forces.

By then end of the book, I could see the oak table next to me as swarming with energy and activity. Uncountable electrons around and between and among billions of nucleii. And these hard, heavy centers of atoms, while held in a rigid grid also vibrate with activity, exchanging baryons, muons, mesons, and other particles while held rigidly together.

Even a glimpse into the mind of Feynman is as exciting as a story of discovering a new world.
