Murray Gell-Mann, Jewish American physicist, passes away

Murray Gell-Mann (89), a Jewish American physicist who theorized the existence of the quark and won a Nobel Prize for his method of classifying particles, has passed away in New Mexico on May 24, 2019. He transformed physics by devising a method for sorting subatomic particles into simple groups of eight, based on electric charge, ..

Baryons and Omega C-0 Particles

In March 2017, five new sub-atomic particles were discovered by Large Hadron Collider scientists at CERN. These particles have been collectively called Omega C0 and have been named Oc(3000)0, Oc(3050)0, Oc(3066)0, Oc(3090)0 b Oc(3119)0 as per their masses megaelectronvolts (MeV). Omega-c-zero is a baryon. It is a particle with three quarks, containing two strange and ..

Neutrinos and Neutrino Oscillation

Neutrinos are one of the elementary particles, which make up the universe. They are similar to electrons except that they do not carry electric charge. As they are electrically neutral, they are not affected by the electromagnetic forces like electrons or protons. Neutrinos are only leptons with no electric nature. Other leptons, which carry electric ..

2012 Physics Nobel for Haroche and Wineland

Serge Haroche of France and David Wineland of America together won the 2012 Nobel Prize in Physics for inventing methods to observe the bizarre properties of the quantum particles without disturbing them. This thing was previously thought unattainable. What is their invention? Their inventions are the methods by which quantum particles like atom, electron or ..

Neutrinos: Faster than Light? It’s proved

It has been generally assumed that neutrinos travel at the speed of light. According to the theory of relativity, if neutrinos are massless, they must travel at the speed of light. However, if they carry a mass, they cannot reach the speed of light. There have been various theories regarding the speed of Neutrinos. It ..
