The incompleteness of relativity and quantum theories So, for me, there’s always been a nagging shortfall of visualization for the major theories of modern physics: Relativity and Quantum theories. Successful theories indeed. But a focus on the mathematics, with some hand-waving surrounding implicit assumptions (or definitions), conveying a flawless formulation in popular presentations. As discussed… Continue reading Special relativity’s fundamental defect – ether redux
[“What’s changed in the last 50 years” series] Another interesting Symmetry Magazine article – a historical recap of the Standard Model and some highlights. • Symmetry Magazine > “Six fabulous facts about the Standard Model” by Sarah Charley ( March 16, 2021) – Learn about the Standard Model of particle physics and how physicists use… Continue reading Particle zoo to Standard Model and beyond
Paraphrasing: Just a note before you go,A vision to be learnedTraveling near the speed of lightIt’s easy to get … Imagining how things would look when traveling near the speed of light is an interesting exercise. Using a freeware video game developed by MIT Game Lab (2012), this visualization (below) by The Action Lab is… Continue reading Sightseeing near the speed of light – realistic simulation
[“Quantum foundations” series] A physicist walks into a bar, and asks the bartender, “What time is it?” The bartender is about to reply but then recognizes the customer. “You’re a physicist, correct? So, it’s a trick question.” So, what’s with time? A venerable philosophical question. A foundational question in physics. We have electronic devices, extremely… Continue reading Whence the arrow of time?
I’ve thought about this question for years. A FAQ. Imagine you’re traveling at the speed of light. Well, physics says that’s impossible. Mass’ gotcha. So, what can travel at the speed of light? Photons (not just the visible ones). So, imagine … does a photon “experience” space and time? Some weeks ago I recall reading… Continue reading A photon’s frame of spacetime — no rest for the massless
