AI Overview [summarize the key points of Carlo Rovelli's book Helgoland: Making Sense of the Quantum Revolution] In Helgoland: Making Sense of the Quantum Revolution, Carlo Rovelli argues that quantum mechanics can be understood as a theory describing how objects […]

Also from my to-do list for commentary … an interview. Here's an article (below) about Gerard 't Hooft's dissatisfaction with quantum mechanics. (Is this the same as quantum physics?) Not a hint of visualization. 't Hooft seeks to explain quantum […]

Well, on my to-do list for commentary, there're a few more articles by well-known physicists. Here's a recent one by Brian Cox (below). PROLOGUE Before my take on Cox's presentation (below), here's my take on quantum physics. Here's a quick […]

(Image credit: NASA via collectSPACE.com) The Mars way or the Artemis path forward – a lunar gateway? Might other nations take the "slower" (less risky) path? As if I'd anticipated the follow-on to my last comment: • Wired > "Moon or […]

Yeah, about those "new and beautiful horizons." As if you're Queen Isabella financing Christopher Columbus's 1492 voyage to the New World, thinking about the future of civilization? That awesomeness. Manifest pomp. There's no fooling Mother Nature (orbital physics). Is Mission […]

This magazine article (below) includes a YouTube video "Sneak Peek at Simulated Mars Habitat at NASA's Johnson Space Center" (Nov 8, 2022), which introduces NASA's first CHAPEA (Crew Health and Performance Exploration Analog) mission, an Earth-based 378-day 4-person "Mars Dune […]

Well, here we go again … yet another recap … although it's really about fields (QFT) … but here there be 'particle' words … quantum particles, photons – real & virtual … here there be Feynman diagrams … (virtual) mediation […]

(caption) Cover of the book "A City on Mars: Can We Settle Space, Should We Settle Space, and Have We Really Thought This Through" about colonizing Mars No guts, no glory … tragedy or triumph? Is "Occupy Mars" the best […]

Yeah! A diagram using wavepackets (not just sine / cosine plain waves). Superposition. And then determining "how long the electrons remain in a superposition before they relax back to their starting state." • Caltech > News > "Quantum Sensing Using […]

Active research on FRBs (fast radio bursts) continues. "… questions linger about the nature of FRBs, including why a handful seem to go off multiple times a day while others flash only once." • Space.com > "Where do fast radio […]
