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 in a Euclidean space using the… Continue reading Symmetry → connection field → force of nature

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
