Yesterday’s big post on why I think people should embrace scientific thinking in a more conscious way than they do already (because my claim is that most people already use scientific thinking, they’re just not aware that they’re doing it) is clearly a kind of explanation of the reason behind my next book, but what… Continue reading Modern Physics and Scientific Thinking

How Good Are Polarized Sunglasses?
A while back, I explained how polarized sunglasses work, the short version of which is that light reflected off the ground in front of you tends to be polarized, and by blocking that light, they reduce the effects of glare. This is why fishermen wear polarized sunglasses (they make it easier to see through the… Continue reading How Good Are Polarized Sunglasses?
The Test(ing) of Time 2: Freezing Time
A month and a half ago, I reported on a simple experiment to measure the performance of a timer from the teaching labs. I started the timer running at a particualr time, and over the next couple of weeks checked in regularly with the Official US Time display at the NIST website, recording the delay… Continue reading The Test(ing) of Time 2: Freezing Time
What’s So Interesting About Ultracold Matter?
The first of the five categories of active research at DAMOP that I described in yesterday’s post is “Ultracold Matter.” The starting point for this category of research is laser cooling to get a gas of atoms down to microkelvin temperatures (that is, a few millionths of a degree above absolute zero. Evaporative cooling can… Continue reading What’s So Interesting About Ultracold Matter?
What Goes Around Is Really Round: “Improved measurement of the shape of the electron”
The big physics story of the week is undoubtedly the new limit on the electric dipole moment (EDM) of the electron from Ed Hinds’s group at Imperial College in the UK. As this is something I wrote a long article on for Physics World, I’m pretty psyched to see this getting lots of media attention,… Continue reading What Goes Around Is Really Round: “Improved measurement of the shape of the electron”
Why So Many Theorists?
When I was looking over the Great Discoveries series titles for writing yesterday’s Quantum Man review, I was struck again by how the Rutherford biography by Richard Reeves is an oddity. Not only is Rutherford a relatively happy fellow– the book is really lacking in the salacious gossip that is usually a staple of biography,… Continue reading Why So Many Theorists?
Bouncing Neutrons for Fun and Science: “Realization of a gravity-resonance-spectroscopy technique”
Several people blogged about a new measurement of gravitational states of neutrons done by physicists using ultracold neutrons from the Institut Laue-Langevin in France. I had to resort to Twitter to get access to the paper (we don’t get Nature Physics here, and it’s way faster than Inter-Library Loan), but this is a nice topic… Continue reading Bouncing Neutrons for Fun and Science: “Realization of a gravity-resonance-spectroscopy technique”
Massive by Ian Sample
The physics book generating the most bloggy buzz in the latter part of 2010 would have to be Ian Sample’s Massive: The Missing Particle that Sparked the Greatest Hunt in Science, about the as yet undetected particle known as the Higgs boson. Detecting the Hiigs is the most immediate goal of the Large Hadron Collider,… Continue reading Massive by Ian Sample
The Status of Simulations
Most of what would ordinarily be blogging time this morning got used up writing a response to a question at the Physics Stack Exchange. But having put all that effort in over there, I might as well put it to use here, too… The question comes from a person who did a poster on terminology… Continue reading The Status of Simulations
Poll: Top Physics Story of 2010?
It’s the last week of the (calendar) year, which means it’s a good time to recap the previous twelve months worth of scientific news. Typically, publications like Physics World will publish a list of top ten physics stories of 2010, but we’re all Web 2.0 these days, so it seems more appropriate to put this… Continue reading Poll: Top Physics Story of 2010?
