I just finished reading Feynman’s “QED: The Strange Theory of Light And Matter” (henceforth ‘QED’) and, in the context of my post on reading more, I would like to give you a writeup of my thoughts. ‘QED’ is a pop-sci book covering the quantum theory of electromagnetism known as quantum electrodynamics. ‘QED’, however, takes a slightly different approach of presenting the science; it does not dumb things down to give you the illusion of understanding. For me, personally, the book was a breeze to read due to the fact that I am already familiar with most of these concepts from my physics studies. However, let’s look at this book from the perspective of the layperson instead. Do Feynman’s explanations still hold up? I think they do.

The popular culture picture of quantum mechanics is highly inaccurate. The word “quantum” has become synonymous with weird and wacky physics. “In quantum physics, a cat can be dead and alive at the same time!”, people say. In this article I will attempt to explain QM in a way that people can understand as well as shed light on the infamous cat, while utilising minimal notation and mathematics.
