How Do You Trap an Ion, Anyway?

One of the many physics stories I haven’t had time to blog about recently is the demonstration of relativistic time effects using atomic clocks. I did mention a DAMOP talk about the experiment, but the actual paper was published in Science (and is freely available from the NIST Time and Frequency Division (PDF file), because… Continue reading How Do You Trap an Ion, Anyway?

Pre-Veterans Days

I usually have ESPN on as background noise in the morning, but I turned it off today because their increasingly fulsome tributes to Veterans Day were getting on my nerves.

Thus, a poll: You are a college student considering an elective class in your major, and you see it has a lab. Your reaction is:survey software Feel free to… Continue reading Academic Poll: Course Selection

How to Teach Quantum Physics to Your Dog: Obsessive Update

I haven’t been doing these as regularly as I was earlier in the year, but here are a few interesting bits of news about How to Teach Physics to Your Dog: LA FISICA SPIEGATA AL MIO CANE, is now available. That’s the Italian edition, which Google translates to something like “Explaining Physics to My Dog.”… Continue reading How to Teach Quantum Physics to Your Dog: Obsessive Update

Physics Job Market: Same As It Ever Was

The American Institute of Physics has a statistics division that produces lots of interesting analyses of issues relevant to the discipline. A couple of them were released just recently, including one on the job status of new Ph.D.’s (PDF). The key graph from the report is this one: The text of the report talks up… Continue reading Physics Job Market: Same As It Ever Was
