The Elementary Particle Dilemma for UPSC CSE Aspirants: Dalton's atomic theory was a big step forward. We now know that all matter, except dark matter, is made of molecules, which are themselves made of atoms. Inside the atoms, there are electrons spinning around the nucleus. The nucleus itself is generally made of protons and neutrons but even these are composite objects. With the advent of particle accelerators this picture has changed. 1. Matter particles All matter around us including stars, planets and even life is made of elementary particles, the building blocks of matter. These particles occur in two basic types called quarks and leptons. Collectively they are called fermions. 12 types of elementary fermions: 6 quarks and 6 leptons. EXAMPLE ELECTRONS, NEUTRINOS
The Elementary Particle Dilemma for UPSC CSE Aspirants.....continued 2. Forces and carrier particles There are four fundamental forces at work in the universe: the strong force, the weak force, the electromagnetic force, and the gravitational force. 3 of the fundamental forces result from the exchange of force-carrier particles, which belong to a broader group called "bosons". Each fundamental force has its own corresponding boson .the strong force is carried by the "gluon", .the electromagnetic force is carried by the "photon" .the "W and Z bosons" are responsible for the weak force. Although not yet found, the "graviton" should be the corresponding force-carrying particle of gravity.
The Elementary Particle Dilemma for UPSC CSE Aspirants.....continued Standard Model The Standard Model is the simplest set of ingredients - elementary particles needed to make up the world we see in the heavens and in the laboratory. The theoretical framework that describes the interactions between elementary building blocks (quarks and leptons) and the force carriers (bosons) is known as the standard model. s and leptons) and the forc neractions been
James Webb Space Telescope The JWST will be located near the second Lagrange point (L2) of the Earth-Sun system. rmal sucessr o the iubale seace eee lis and ince te jasone wsT JWST is the formal successor to the Hubble Space Telescope (HST), and since its primary emphasis is on infrared observation, it is also a successor to the Spitzer Space Telescope. JWST will far surpass both those telescopes, being able to see many more and much older stars and galaxies. The Hubble Space Telescope (HST) was launched into low Earth orbit Great Observatories The Hubble Space Telescope The Compton Gamma Ray Observatory The Chandra X-ray Observatory The Spitzer Space Telescope
LADEE MISSION Lunar Atmospheric Dust Ern Lunar Atmospheric Dust Environmental Explorer. t was alunar robotic mision of NASA thatwill obit the monto gather detaied It was a lunarrobotic mission of NASA that will orbit the moon to gather detailed information about the lunar atmosphere, conditions near the surface and environmental influences on lunar dust.
Brown dwarfs Brown dwarfs are substellar objects that occupy the mass range between the heaviest gas giant planets and the lightest stars Unlike the stars in the main-sequence, brown dwarfs are not massive enough to sustain nuclear fusion of ordinary hydrogen to helium in their cores.
GRAPES-3 The GRAPES-3 experiment located at Ooty (??) in India started as a collaboration of the Tata Institute of Fundamental Research, Mumbai, India and the Osaka City University, Osaka, Japan. GRAPES-3 (Gamma Ray Astronomy PeV Energie Sphase-3) is designed to study cosmic rays with an array of air shower detectors and a large area muon detector.
