Hendrik Casimir and John Ward
Hendrik Brugt Gerhard Casimir was born in the Hague in the Netherlands in 1909 and received his PhD from the University of Leiden in 1931. After working with Bohr in Copenhagen and Pauli in Zurich, he...
Boost for particle physics in Canada
“This renewal of funding will permit TRIUMF to become a world leader in particle physics research,” said Arthur Carty, President of National Research Council. “It will also retain an...
CERN claims quark-gluon first
In the CERN experiments a 33 TeV lead ion beam was crashed into targets made of lead and gold inside the seven different experimental detectors. The collisions created energy densities twenty times th...
CERN-Gran Sasso neutrino experiment is approved
Italy is paying over half of the cost of the SwFr 71million experiment, with voluntary contributions from Belgium, France, Germany and Spain covering the rest. The experiment will start taking data in...
Physicists look to neutrino factory
When charged particles move in a circle they lose energy through synchrotron radiation. However, muons lose much less energy that electrons or positrons because they are 200 times heavier. This reduce...
New upper limit to neutrino mass
The team studied the radioactive decay of germanium 76, which cannot occur by normal beta decay in which one electron and one antineutrino would be emitted. The nucleus can, however, undergo double be...
E-beams tackle E. coli
For over a century milk has been pasteurised by heating it to 65 degrees Celsius for 30 minutes and then rapidly cooling it to below 10 degrees Celsius for storage. The new technique relies on energet...
Could carbon-60 molecules be used in particle physics?
As the highly energetic particles pass through conventional carbon-rich rocks, they would form carbon-60 molecules in their wake. The fact that these geological detectors have been “collecting d...
Nobel prize goes to ‘t Hooft and Veltman
‘t Hooft and Veltman were both born in the Netherlands. In 1966 Veltman was appointed as professor of physics at the University of Utrecht, and ‘t Hooft became his PhD student in 1969. By ...
Top quark and Bell’s inequalities top PhysicsWeb Nobel poll
Every year the Foundation asks 3000 physicists to nominate individuals for the prize, and compiles a short-list of 250 candidates. These names are then whittled down to a list of 30, from which the wi...
