  • Cosmic ‘bumps in the night’ – DSA advances radio astronomy
    Black holes, supernovae, neutron stars, pulsars, oh gee,… radio beasts in a gravitational sea … Radio telescopes have been the workhorses of cosmic sky surveys for a long time. Yet, often eclipsed in public media by the Hubble and Webb […]
  • ‘The world will never fit inside an equation’
    We venture once again to the Moon! Let us do so with humility, inspired by the interplay of light & shadow, mankind’s history of rise & fall. The Moon Is a Harsh Mistress and “There Ain’t No Such Thing As […]
  • Quantum physics beyond remembrances – decoherence redux
    A new Quanta Magazine article by Philip Ball was so refreshing that I had to pause working on my other blogs and stories, and follow up on my past posts about wavepackets [1]. So, wavepackets and Wilczek’s Grid continue to […]
  • AIsaysWhat.physics – the take of scrape – wavepacket chat
    Introduction My chat with Gemini about photons continued this week. This time I explored its take on visualization of a photon as a wavepacket. A traveling energy bundle, quantum of the electromagnetic field (aka photon field). A model that’s more […]
  • AIsaysWhat.physics – the take of scrape – photon chat
    Introduction Last month I saw an uptick in my Google Web traffic for the question “How big [or large] is a photon?“ I’ve been exploring AI chabot takes on various topics for a while. So, I recently asked Google that […]
  • Chirality – the mirror mismatch
    Hold your right hand in front of a mirror. Or, just place your left hand in front of your right with palms facing. Now (in 3D) try to “swap in” (superpose) your left for your right hand. It’s not a […]
  • Enough cat in a box! – an isolation setup
    I’ve cited Nick Lucid’s Science Asylum YouTube channel over the years. His latest video is a wonderful take on all the quantum cat clickbait which I’ve noticed lately – another nostalgic set of pieces on Schrödinger’s legendary thought experiment. Much […]
  • Reframing spacetime – a stitch of events or pitch of time
    In quantum field theory, if gravity isn’t a fundamental force, how does it emerge? This article describes a theory of deep quantum electromagnetic interactions. Photon transactions (emission / absorption) populate a relational network of events which structures spacetime. According to […]
  • Senior health in space – longevity in freefall
    The romance of living in space and space travel skyrocketed as I was growing up. Post WWII. Sputnik, Disney’s Man in Space, NASA’s man on the moon, Star Trek, … classic sci-fi books … Maybe back then millionaires dreamed of […]
  • Advancing QFT visualization – further demystification?
    [Draft 1-6-2025 see comments for updates] Yeah, quantum physics is weird. What might be called Weirdness 1.0 (QM), 1.1 (QED), 1.2 (QCD), etc., as I’ve written about, have embedded frozen tropes in the popular psyche. But can’t we do better? […]
