Big sim’s – visualizing the universe!

Taking all-sky surveys / maps to another 10^n level of visualization … So much of modern cosmology depends on the discovery of the cosmic microwave background (CMB) radiation in 1965. Wiki: “Any proposed model of the universe must explain this radiation.” Since then, advances in the tools to measure and analyze that faint, relic radiation… Continue reading Big sim’s – visualizing the universe!

All-sky surveys – visualizing our dynamic galaxy

Advances in all-sky surveys permit better visualization of the motions and dynamics inside our galaxy. And provide a better understanding of the evolution of the Milky Way. X-ray all-sky surveys As noted in this Space.com article, while “optical telescopes are much easier to design than X-ray telescopes … some of the most interesting objects in… Continue reading All-sky surveys – visualizing our dynamic galaxy

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
