Best Blogging of the Year

Bora’s beating the drum for submissions to this year’s science blogging anthology. He doesn’t seem to be suffering from a lack of submissions, but if you’ve got something you would like to see re-printed in dead tree form, submit it before December 1. I’m not clear whether this will be going through Lulu again this… Continue reading Best Blogging of the Year

Physics Books for Middle Schoolers?

Sometime commenter “Dr. Pain” asked, on a mailing list, for book recommendations for his son, who “wants to read up about physics, especially weird modern physics.” He adds some qualifications: Kid’s books on physics are way too elementary for him, but the typical “naive adult” book is over his head. Does anyone have any good… Continue reading Physics Books for Middle Schoolers?

Many-World vs. Multiverse

In the recent discussion of Many-Worlds and making universes, Jonathan Vos Post asked what science fiction treatments of the idea I like. The answer is pretty much “none,” because most SF treatments are distractingly bad. For example, last night I finished Neal Stephenson’s Anathem, a whopping huge brick of a book setting up an incredibly… Continue reading Many-World vs. Multiverse

What’s the Matter with Making Universes?

In a comment on a post from last week, Neil B. Asks a good question about my snarky response to the “make-your-own-universe” kit: [Y]ou never explained why this “universe creator” could be considered based on a misapprehension. Considering the way multi-worlds QM theory is usually presented, IIUC; why would you (anyone?) say it doesn’t work… Continue reading What’s the Matter with Making Universes?

Puzzling Solar Panel Press Release

Getting back to science, at least for the moment, I was puzzled by a press release from RPI, with the eye-catching headline Solar power game-changer: ‘Near perfect’ absorption of sunlight, from all angles. The article describes work published in Optics Letters (that I haven’t been able to put my hands on yet), developing new anti-reflection… Continue reading Puzzling Solar Panel Press Release

Quantum Computing Candidates: Liquid State NMR

Continuing the series of descriptions of candidate technologies for making a quantum computer (previous entries covered optical lattices and ion traps), we come to one that’s a little controversial. It’s the only remaining candidate I can describe off the top of my head without doing some more background reading, though, so I will plunge ahead… Continue reading Quantum Computing Candidates: Liquid State NMR

Universes Are Cheaper in Bulk

Via Boing Boing, a “conceptual artist” is selling a make-your-own-universe kit: According to [a slightly garbled explanation of quantum mechanics], any kind of measurement causes the universe to split and this is the basis of Keats’ new device. His universe creator uses a piece of uranium-doped glass to create a steam of alpha particles, which… Continue reading Universes Are Cheaper in Bulk
