Problem - Compute the potential difference between the points (4,6,3) and (8,1,6) due to a constant electrostatic field given by E =...

This semester I’m teaching General Relativity, and as part of discussing gravitational waves, this week I briefly discussed pulsars. It was quite timely therefore when I learned of a new proposal that pulsars may ultimately provide a perfect navigation system for spacecraft far from Earth. Here on Earth, the Global Positioning System (GPS) gives us [...]
An international collaboration of scientists has reported a landmark calculation of the decay process of a kaon into two pions, using breakthrough techniques on some of the world's fastest supercomputers.

How best to represent data is a question that physicists spend a lot of time thinking about. While theorists like myself are not the primary examples of this, I do find it striking when I stumble upon an example of data visualization that gets the pertinent facts across in a significantly clearer way than I’ve [...]
The Majorana Demonstrator collaboration began moving their experiment into the Davis Campus on the 4850 Level this week.

Not wanting to let Sean get away with the only marshmallow-related post this year, I’d like to bring to your attention that, for the fifth year running, the Washington Post recently held its Peeps Diorama Contest.

If attendees at the welcome reception for CERN’s first artist-in-residence learned one thing last night, it was that Julius von Bismarck is not afraid to disrupt others with his art.
Can you think of any? Here’s what I mean. When we set about justifying basic research in fundamental science, we tend to offer multiple rationales. One (the easy and most obviously legitimate one) is that we’re simply curious about how the world works, and discovery is its own reward. But often we trot out another [...]
The decommissioning of the Tevatron represented the end of an era, but it also is ushering in the next generation of physics by providing valuable equipment to other experiments.

(Somehow there is a good pun lurking there, but at the tail end of a bout with the flu, I’m not finding it…) Anyway, this plot says it all: I’ve taken this image from a new paper posted by the ICARUS Collaboration (arXiv:1203.3433). The ICARUS experiment sees the same neutrino beam that OPERA sees, and [...]
Scientists on the ICARUS experiment at Gran Sasso, Italy, announced today that they had found no evidence of superluminal neutrinos in a cross-check of earlier analysis from the OPERA experiment, also located at Gran Sasso.
We all knew that when the OPERA experiment announced preliminary evidence that neutrinos were traveling faster than the speed of light, the result was so hard to swallow that independent confirmation from other experiments would be necessary before too many people jumped on the bandwagon. In the meantime, a number of theoretical papers pointed out [...]
Retired CERN physicist Cristoforo Benvenuti learned a thing or two about building a better solar panel through his work on particle accelerators. The Geneva International Airport recently ordered 300.
Scientists recently proved possible a way to converse when radio waves won’t do. For the first time, physicists have successfully transmitted a message using neutrinos.
The Tevatron may be shut down for good, but – as evidenced by the catalogue of results presented at this week’s Rencontres de Moriond conference – the collider’s experiments still have plenty to say. In some areas, the Fermilab experiments still hold the advantage over those at the higher-powered Large Hadron Collider at CERN.
On March 7, Alan Alda, the actor best known for playing medic Hawkeye Pierce on yesteryear’s TV series M*A*S*H, visited the home of the Large Hadron Collider, CERN.
