A couple of reviews, an offer, and a mystery regarding How to Teach Physics to Your Dog: The reviews: A review at suite101 that went up a while ago, but I somehow missed in the vanity search. It’s a nice, detailed review, and if I had to pick a pull quote it would probably be:… Continue reading How to Teach Physics to Your Dog: Obsessive Update

The Faulty Fluid Dynamics of Hotel Environmentalism
Boskone this past weekend was held at the Westin Waterfront in Boston, which has these funky double showerheads that they charmingly call the “Heavenly(R) Shower” (hype aside, they are very nice showers). The picture at right is courtesy of lannalee on Twitter, as I didn’t bring a camera. Why am I telling you this? Because… Continue reading The Faulty Fluid Dynamics of Hotel Environmentalism
Amazing Laser Application 4: Optical Tweezers!
What’s the application? Optical tweezers use focused light beams to trap small particles in the focus of the beam, and drag them around by moving the beam. What problem(s) is it the solution to? 1) “How do we move these tiny little things around without touching them?” 2) “How do we measure the forces exerted… Continue reading Amazing Laser Application 4: Optical Tweezers!
Entanglement Happens
There have been a bunch of stories recently talking about quantum effects at room temperature– one, about coherent transport in photosynthesis , even escaped the science blogosphere. They’ve mostly said similar things, but Thursday’s ArxivBlog entry had a particular description of a paper about entanglement effects that is worth unpacking: Entanglement is a strange and… Continue reading Entanglement Happens
How to Teach Physics to Your Dog: Obsessive Update
Miscellaneous stories and links about How to Teach Physics to Your Dog: — There’s a nice review by Margaret Fisk (who has been reading it for a while, and mentioning it on her blog, which kept turning up in the vanity search): Orzel does a wonderful job of finding physical parallels to explain quantum concepts… Continue reading How to Teach Physics to Your Dog: Obsessive Update
Amazing Laser Application 3: Lunar Laser Ranging!
What’s the application? Measuring the distance from the Earth to the Moon by bouncing a laser off one of the retro-reflector arrays left there by the Apollo missions. What problem(s) is it the solution to? 1) “How does the distance from the Earth to the Moon vary over time due to things like tidal drag?”… Continue reading Amazing Laser Application 3: Lunar Laser Ranging!
Amazing Laser Application 2: Laser Cooling!
What’s the application? Using lasers to reduce the speed of a sample of atoms, thereby reducing their temperature to a tiny fraction of a degree above absolute zero. What problem(s) is it the solution to? 1) “How can I make this sample of atoms move slowly enough to measure their properties very accurately?” 2) “How… Continue reading Amazing Laser Application 2: Laser Cooling!
Amazing Laser Application 1: Light Show!
What’s the application? The use of lasers to provide an entertaining light show for humans, dogs, or cats. What problem(s) is it the solution to? 1) “How will I entertain my dog or cat?” 2) “How can we distract people from the fact that Roger Daltrey has no voice left?”
Laser Smackdown: The Finalists
A couple of weeks ago, I announced a contest to determine the Most Amazing Laser Application. After a follow-up post listing the likely candidates, we have a final list of candidate applications, an even dozen of them (after consolidating some related topics): Cat toy/ dog toy/ laser light show Laser cooling/ BEC Laser ranging/position measurement… Continue reading Laser Smackdown: The Finalists
Talking to My Dog About Science: Why Public Communication of Science Matters, and How Weblogs Can Help
My talk at Maryland last Thursday went pretty well– the impending Snowpocalypse kept the audience down, as people tried to fit in enough work to compensate for the Friday shutdown, but the people who were there seemed to like it, and asked good questions. If you weren’t there, but want to know what I talked… Continue reading Talking to My Dog About Science: Why Public Communication of Science Matters, and How Weblogs Can Help
