# Demystifying QFT – Grid as superconductor

Here’s a possible story which helps demystify quantum field theory. A personal visualization, which stays within the bounds of spacetime and avoids needless paradoxes. There are two key concepts to my sketch: the Grid and a quantum’s tail. This post lays out the first idea, namely, the Grid.

# Our friend the atom, mostly empty space?

[Communicating science series] This is a concept often espoused by science popularizers over the decades. Even the background for plot vouchers in some sci-fi adventures. An amazing fact: We and everyday objects around us are mostly empty space! So, miniaturize matter. Fantastic Voyage! Honey, I Shrunk the Kids. Downsizing. That’s why superman could walk through… Continue reading Our friend the atom, mostly empty space?

# Point particles RIP

I typically add samples of books to my Kindle library when considering purchases. While examining my Kindle library yesterday, I started reading a sample of Art Hobson’s 2017 book Tales of the Quantum: Understanding Physics’ Most Fundamental Theory and then became interested in his background. A Google search found biographical information, references to his books,… Continue reading Point particles RIP

# Symmetry → connection field → force of nature

Here’s my take on gauge symmetry after reading about the concept (some references are listed below). There are mathematical frameworks for space, and in physics there are equations of motion for space. A mathematical framework deals with geometric and numeric objects. In everyday life we basically equate these objects with a Euclidean space using the… Continue reading Symmetry → connection field → force of nature

# Reality is fields

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

# GR: Chicken or egg redux

One of the major sources of confusion I’ve encountered in reading about modern physics is the discussion of gravity. No surprise, eh. Classical mechanics includes both Newtonian and relativistic mechanics. In Newtonian physics, gravity is an attractive force, which acts at a distance between all objects; and can be represented as a universal gravitational field.… Continue reading GR: Chicken or egg redux
