January 21, 2021 It All Started with Feynman Diagrams Any serious calculation in particle physics takes a lot of algebra. Maybe it doesn’t need to. But with the methods based on Feynman diagrams that we know so far, it does. And in fact it was these kinds of calculations that first led me to use computers for symbolic computation. That was in 1976, which by now is a long time ago. But actually the idea of doing Feynman diagram calculations by computer is even older. So far as I know it all st...

20 January, 2021 Martinus J. G. Veltman (right) with John S. Bell at CERN in 1973. (Image: CERN) Martinus (“Tini”) Veltman started his scientific career relatively late: he obtained his PhD from the University of Utrecht in 1963 (1) under the supervision of Leon Van Hove, but had already moved to CERN in 1961, where Van Hove had been named Leader of the CERN Theory Division. At CERN, Van Hove studied mainly hadronic physics but Veltman became interested in weak interac...

Ideas, Inventions And Innovations Study: X-Rays Surrounding ‘Magnificent 7’ May Be Traces of Sought-After Particle Researchers say they may have found proof of theorized axions, and possibly dark matter, around group of neutron stars. An artistic rendering of the XMM-Newton (X-ray Multi-Mirror Mission) space telescope. A study of archival data from the XMM-Newton and the Chandra X-ray space telescopes found evidence of high levels of X-ray emission from the nearby Magnificent Seven neutr...

Traces of a Mysterious Particle Predicted Decades Ago May Have Been Detected Evidence of a long-sought hypothetical particle could have been hiding in plain (X-ray) sight all this time. The X-ray emission coming off a collection of neutron stars known as the Magnificent Seven is so excessive that it could be coming from axions, a long-predicted kind of particle, forged in the dense cores of these dead objects, scientists have demonstrated.   If their findings are confirmed, this discovery cou...

Physicist Rohini Godbole Receives The Highest Honour Of Merit From France by Image source: icts.res.in/   Indian physicist and Padma Shri awardee Rohini Godbole has been honoured with the Ordre National du Merite, which is one of the highest distinctions granted by the government of France to honour eminent persons. Godbole is working at the Centre for High Energy Physics (CHEP) at the Indian Institute of Science (IISc), Bengaluru.    In the official communication sent to Dr Godbole, the Fr...

A new study, led by a theoretical physicist at Berkeley Lab, suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars.

Physicists Detect Tantalising Hints of a "Fundamentally New Form of Quantum Matter" 13 JANUARY 2021 Metals and insulators are the yin and yang of physics, their respective material properties strictly dictated by their electrons mobility - metals should conduct electrons freely, while insulators keep them in place.    So when physicists from Princeton University in the US found a quantum quirk of metals bouncing around inside an insulating compound, they were lost for an explanation. Well n...

Massachusetts Institute of Technology In the spring of 1970, colleges across the country erupted with student protests in response to the Vietnam War and the National Guard’s shooting of student demonstrators at Kent State University. At the University of Chicago, where Frank Wilczek was an undergraduate, regularly scheduled classes were “improvised and semivoluntary” amid the turmoil, as he recalls. It was during this turbulent time that Wilczek found unexpected comfort, and a new unders...
