[Draft] [“Quantum foundations” series] [“What’s changed in the last ~50 years” series] TABLE OF CONTENTS The buzz Proving that quantum entanglement is real Media articles Takeaways Notes Related posts THE BUZZ Much buzz on Tuesday October 4, 2022, as media marked the 2022 Nobel Prize in physics. So many articles – a hopeful indication regarding… Continue reading 2022 Nobel Prize – ‘spooky action’ pioneers
[Draft] A recent Caltech News article profiles some research in squeezed states of light. And why that is useful. • Wiki > Squeezed coherent state • Wiki > Squeezed states of light (quote) In quantum physics, light is in a squeezed state if its electric field strength Ԑ for some phases ϑ has a quantum… Continue reading What is ‘squeezed light’?
[“What’s changed in the last 50 years” series] As noted in my January 17, 2019, post “Cosmological fact and fiction,” the Big Bang theory poses questions on “whether terms like ‘origin’ or ‘creation’ even apply; and the limits of language to even discuss the topic.”  So, perhaps a rethink was overdue on the topic,… Continue reading RIP ‘Big Bang’ singularity?
Is communication at faster than the speed of light possible – actual, instantaneous communication across vast distances using entangled (so-called) particles? After a conversation with an acquaintance last June … He was reading Katie Mack’s book re cosmology, and said that entanglement permitted instantaneous communication. He referenced information theory. And that information requires no “embodiment.”… Continue reading Spooky action vs. spooky communication
[Communicating science series][Gobbledygook ahoy, PopSci call-outs, …] “Can particles really be in two places at once?“ So remote from everyday experience: How to describe physical behavior that human communication never evolved to describe? To describe something that the mere act of observation extinguishes? Use an abstract symbolic framework like mathematics? And then “convert” mathematical expressions… Continue reading In two places at once – popsci call-outs
[Draft – more citations to come] Lately I’ve encountered many articles about research on the Higgs boson. Retrospectives, ongoing discoveries, and expectations for the upgraded LHC and its third run. The stuff of careers for 1000’s of scientists. This research is a fascinating effort akin to “particle archeology.” Inferring – detecting evidence for – the… Continue reading Higgs 10 years on – expectations for a path beyond
[“Knot theory” series] Regarding the topology of fundamental particles as spinors, like the electron, I prefer the term knot, rather than kink or twist or vortex . Then I’m curious about ordering the complexity (à la generations) of these knots. And whether such knots are situated in additional dimensions. Wiki: In quantum field theory, the… Continue reading Knotty fields – quantum-topology-knot theory
Do so-called antimatter particles play by the same rules as normal matter? Having an opposite charge from the electron, for example, does the positron obey the same laws of physics? Yes, essentially. (Baryon asymmetry is an ongoing topic of research as to any tiny effective difference.) But what happens to atomic dynamics when an electron… Continue reading Hybrid matter-antimatter atoms?
The context “He [Einstein] could construct complex equations, but more important, he knew that math is the language nature uses to describe her wonders.” – Isaacson, Walter. Einstein: His Life and Universe. Simon & Schuster. Kindle Edition. • YouTube > The Science Asylum > “Is Math the Language of the Universe?” (published 12-31-2016) (video description)… Continue reading A universe without math?
[“Communicating science” series] [“Quantum foundations” series] [“What the heck” series] I’ve written about entanglement in prior posts and comments. Over a year ago, I also wrote some preliminary notes. A recent issue of The Caltech Weekly (April 14, 2022) prompted this post. In part because of my ongoing search for better, more compelling analogies (for… Continue reading What the heck is quantum entanglement?
