The last couple of days at work have been Shop Days, with a fair bit of time spent in the department’s machine shop making holes in a metal box. This would, I’m sure, be the occasion of much hilarity among my old junior high shop teachers, as my ineptitude in both metal and wood shop […]

Seed on the Large Hadron Collider
My Corporate Masters have finally posted the piece that ran in the most recent print edition of the magazine, in which prominent physicists comment on the LHC. They’ve got predictions and explanations of why the LHC is interesting from an impressive array of people. Most of the answers are pretty predictable. Lisa Randall talks about […]
Fun With Diode Lasers
I ended the previous laser post by noting that diode lasers need some additional wavelength selection to be done in order to be useful as light sources for spectroscopy experiments. In their natural state, they tend to emit light over a broader range of wavelengths than is really ideal, and we’d like to narrow that […]
So, CERN Has a Particle Accelerator?
A little while back, JoAnne at Cosmic Variance reported on the status of the Large Hadron Collider (LHC), the giant next-generation accelerator that is the cover story for the current print issue of Seed. Particle experimentalist Gordon Watts reports in with some more technical details about the delay in the proposed turn-on schedule. He’s also […]
Simulate This
Rob Knop has another post to which I can only say “Amen!”, this time on the relatioship between simulation and experiment (in response to this BoingBoing post about a Sandia press release): Can simulations show us things that experiments cannot? Absolutely! In fact, if they didn’t, we wouldn’t bother doing simulations. This has been true […]
Physics Funding Fundamentalism
The big physics story of the day is bound to be this new report on American particle physics: The United States should be prepared to spend up to half a billion dollars in the next five years to ensure that a giant particle accelerator now being designed by a worldwide consortium of scientists can be […]
True Lab Stories: The Definition of Insanity
I’m still feeling pretty lethargic, but I hope that will improve when I get to lecture about the EPR paradox in Quantum Optics today (it’s going to be kind of a short lecture, unless I can ad-lib an introduction to Bell’s Theorem at the end of the class, but then I’ve been holding them late […]
Every Day I Write (in) the (Lab) Book
One of the features I always like in the print edition of Seed is the lab notebook pictorial. Every month (or, at least, all three of the months that I’ve looked at the print edition), they publish a reproduction of a page or two from the lab notebook of a working scientist. It’s sort of […]
Gravitomagnetic Noise
A reader emails to ask if I can make sense of this announcement from the European Space Agency: Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity […]
Top Eleven: We Have a Winner!
The votes are in, and have been carefully tabulated by our bleary-eyed accounting firm (that is, me– I would’ve posted last night, but I went to see Chuck D speak (because I’m down with the old-school rap), and he went on for more than two hours…) . What looked like a runaway victory for Michelson […]
