In reading about vibrations in fields and wave functions and wave packets, some words that start with ‘e’ occurred a lot: eigenvalue, eigenvector, eigenfunction, eigenvalue equation, eigenequation . I needed to refresh my understanding of the mathematical models for macroscopic and microscopic systems . Everyday we are surrounded by things that vibrate when excited. Some… Continue reading Eigen what?
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
