While studying physics this past year, I noticed tension between theoretical and experimental physicists, especially between younger quantum field theoreticians and veteran particle physicists — regarding deep reality and the various formulations of quantum mechanics (addressed in another post). Revisiting some archived debates, this philosophical question (“Is reality digital or analog?”) was posed in an essay… Continue reading Is reality digital or analog?
Over the weekend, I started reading Sean Carroll’s The Particle at the End of the Universe. Well written . At times his colloquial description of a concept prompted me to: (1) wonder if he was referring to a particular technical phenomenon; and (2) explore the specialized, technical background of that concept. In either case, quite… Continue reading Vocabulary at the end of the verse
So, here’s the thing. If I roll with Quantum Field Theory (QFT), how do I reconcile my macroscopic and microscopic views of things. Simple things. Like looking at a tiny candle across the room? “P vision” Imagine if we could see individual photons (without being overwhelmed by visual “noise” in very low light). Where might… Continue reading Beyond frog vision
Physics was a requirement for the first two years when I was an undergrad. That introduced me to The Feynman Lectures on Physics, three heavy red volumes (© 1963, 1964, 1965). The preface in each volume had a picture of Feynman playing the bongo drums. And then the early morning physics labs. Two of the… Continue reading Reality is fields
