Shameless (if Belated) Self-Promotion: Me on the Radio

If you want to know how stressed and busy I’ve been lately, you don’t have to look any farther than the fact that I’ve totally fallen down on the shameless self-promotion front: I was on a radio show, and forgot to post about it here. I know, bad blogger, no pageviews… Anyway, I talked about… Continue reading Shameless (if Belated) Self-Promotion: Me on the Radio

Congratulations to Perlmutter, Schmidt and Riess, and also Evan and Cusp

The 2011 Nobel Prize in Physics goes to Saul Perlmutter, Brian P. Schmidt and Adam G. Riess “for the discovery of the accelerating expansion of the Universe through observations of distant supernovae.” Ethan will presumably have a post with about a gigabyte worth of images in it shortly, or if you prefer your information in… Continue reading Congratulations to Perlmutter, Schmidt and Riess, and also Evan and Cusp

Faster Than a Speeding Photon: “Measurement of the neutrino velocity with the OPERA detector in the CNGS beam”

There have been a lot of pixels spilled over this faster-than-light neutrino business, so it might not seem like something I should take time away from pressing work to write up. It is the story of the moment, though, and too much of the commentary I’ve seen has been of the form “I am a… Continue reading Faster Than a Speeding Photon: “Measurement of the neutrino velocity with the OPERA detector in the CNGS beam”

Neutrino Hypotheses Non Fingo

The final sentence of the neutrino paper that everybody is buzzing about: We deliberately do not attempt any theoretical or phenomenological interpretation of the results. From a somewhat older work in physics: Rationem vero harum gravitatis proprietatum ex phænomenis nondum potui deducere, et hypotheses non fingo. Quicquid enim ex phænomenis non deducitur, hypothesis vocanda est;… Continue reading Neutrino Hypotheses Non Fingo

How to Teach Relativity to Your Dog: The Cover

I’m looking at an email from my editor when Emmy wanders by the computer, sniffing around just in case a crumb of food has fallen on the floor in the last five minutes. “Hey,” I say, “Come here and look at this.” “Look at what?” “This:” “It’s the cover for my new book.” “A-hem.” “OK,… Continue reading How to Teach Relativity to Your Dog: The Cover

Greenhouse Physics and Car Shades

I got a new comment on an old post asking an interesting question about thermodynamics: I have a question that bears somewhat on this issue of keeping cars parked in the sun, cooler. You all know those accordion folded/aluminized shades you can put up inside the windshield and back window. Seems to me putting them… Continue reading Greenhouse Physics and Car Shades
