Helgoland? – escape from quantum island

[“Quantum foundations” series] Carlo Rovelli’s new book Helgoland – Making Sense of the Quantum Revolution is in the news cycle this week, with promo’s and reviews. (Probably more comments later.) (quote) Helgoland is a book by Italian physicist Carlo Rovelli. It is about quantum mechanics and its relational interpretation. The title refers to Werner Heisenberg’s… Continue reading Helgoland? – escape from quantum island

Imaging atoms – seeing the impossibly small

When not merely obscured in our field of view, things which we cannot see – that are essentially invisible – often may be either impossibly distant or impossibly small (among other factors). That’s why we have telescopes and microscopes. At cosmic scales, imaging a black hole was like seeing something spanning “the size of a period… Continue reading Imaging atoms – seeing the impossibly small

Evidence for new physics? > Fermilab’s Muon g-2 results announced

As noted in comments for my “The future of (particle) physics?” post, the first results from Fermilab’s Muon g-2 experiment are a big deal for physics. Waiting for years. Highly anticipated. As expected, today these results were officially released. Fermilab itself released an excellent YouTube video visualization which includes background on the project and experiment… Continue reading Evidence for new physics? > Fermilab’s Muon g-2 results announced

Time crystals? – crystal patterns in space and time

Frank Wilczek referenced this topic – time crystals – in his latest book (Fundamentals: Ten Keys to Reality). Time crystals are physical systems that spontaneously settle into stable loops of behavior. I proposed this concept in 2012, and many interesting examples have been discovered since then, both theoretically and experimentally. A recent example is close to… Continue reading Time crystals? – crystal patterns in space and time

Quantum dots – not just for TVs

So, occasionally I run across articles which mention quantum dots; but more frequently I notice this technology promoted in higher quality flat screen displays and TVs. Photo-luminescent nanotechnology. This Phys.org article (below) reminds me that the technology is critical in quantum information processing, e.g., quantum computing. And as Wiki notes, modeling quantum dots showcases the… Continue reading Quantum dots – not just for TVs

Celebrating 20 Years of Human Presence on the ISS

Lots of media news this week, as the ISS celebrates 20 years [on November 2] of continuous human presence aboard the orbiting laboratory. • Overview of operations [PDF] The ISS is approximately 260 miles above the surface of the Earth, just a bit farther than the distance between Washington, D.C. and New York City. The… Continue reading Celebrating 20 Years of Human Presence on the ISS
