E = mc² The Holy Grail of modern physics is a so-called theory of everything, a unified field theory, a theory which unifies all known “forces.” That is, unifies all the fundamental interactions of nature. The three “quantum” interactions (electromagnetism, weak, strong) and gravitation. A conventional sequence of theories depicts final unification as occurring at… Continue reading Making matter from light – ultra energies and unification of forces
I’ve encountered some articles recently about the current state of particle physics. Or, more broadly, “the direction of theoretical physics .” Concerns about its future. Whether new particle accelerators are needed (or even viable). An expensive rabbit hole. That research has become mired in wishful elegant mathematics. The absence of evidence being evidence of absence. I… Continue reading The future of (particle) physics?
This Space.com article “Hotspot for Cosmic Rays: Touring the Telescope Array Project in Utah” published on May 27, 2017, reminded me that while CERN’s LHC is the current champ of colliders on Earth, other particles which have been raining down on us for billions of years are colliding with Earth’s atmosphere at even higher energies —… Continue reading Up in the sky — faster than a speeding LHC proton
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
