2018 Nobel Prize in Physics awarded

American scientist Arthur Ashkin, French engineer Gerard Mourou and Canadian professor Donna Strickland have been awarded the Nobel Prize in Physics for their work in the field of laser physics. Dr. Ashkin has been awarded the Prize “for the optical tweezers and their application to biological systems. Dr. Mourou and Dr. Strickland have been awarded ..

Applications of Neutrinos

The neutrino is a tiny elementary particle, but it is not part of the atom. They exist in nature. Neutrino has a very tiny mass, no charge and spins half. It interacts very weakly with other matter particles so weakly that every second trillions of neutrinos fall on us and pass through our bodies unnoticed. ..

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 ..

Time Crystals

A time-crystal or a space-crystal is basically an open system which shows time translation symmetry breaking (TTSB). The concept was first proposed by the Nobel laureate Frank Wilczek in 2012. He put forward that a time crystal can spontaneously break the symmetry of time translation. They are related to the concepts of zero-point energy and ..

Gravitational Lensing

Normal lenses such as the ones used in a magnifying glass or a pair of spectacles bends the light rays that pass through them by refraction and focuses the light somewhere (such as in your eye). Gravitational lensing is among the first evidences of Albert Einstein’s general theory of relativity – simply put, mass bends light. The gravitational field of a massive ..

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 ..
