In this article, aspirants can check the Physics optional syllabus for UPSC … statistics couldn’t be tested in real life because they did not have low temperature lab. This question has two components A) Discuss the statistical work itself B) how it revolutionized the field of Physics. It is very much capable of all properties of a substance. The gold experiment studies the arrangement of electrons in an atom. To fill the word limit observe how I’ve narrated the “story” that he sent paper, Einstein got it translated and then published so on… Because in real exam, difficult to recall any concrete points of the B.E.statistics itself. Notify me of follow-up comments by email. At that time, the experimental facilities were not capable of attaining the low temperatures to test such prediction. The standard Particle model of Quantum mechanics is firmly set in the arena of special relativity, where the space-time background is flat. This is because it comes under the basic science module. Relevance to Syllabus of UPSC GSM3: Achievements of Indians in science & technology. Over the years, experiments related to Bose-Einstein Statistics were carried out. Neutrinos are the most abundant massive elementary particles in nature. It revolutionized the field of Physics in two ways: Improved the Standard Model of Particle Physics. Those are sometimes called “ghost particles” because they’re so difficult to detect. He took a gold foil about 1000 atoms thick and a doubly charged helium ions. Cut-off Prediction/speculation = woh mein kartaa nhi. In early 2000s, World’s largest particle accelerator called ‘Large Hadron Collider (LHC)’ was setup at CERN’s laboratory in Europe. The angular momentum problem. Bose-Einstein statistics predicted that at very low temperature near absolute zero, all particles will condense into a single state, called Boson. Introduction: Origin of Bose-Einstein Statistics, Body-1: It improved std.

Standard Particle Model links the matter-energy conversions, with the help of Quarks, Leptons, Gauge Bosons and Higgs Boson. In modern physics, the double-slit experiment is a demonstration that light and matter can display characteristics of both classically defined waves and particles; moreover, it displays the fundamentally probabilistic nature of quantum mechanical phenomena. Neutrinos are the only elementary particles of matter, which do not carry electrical or strong charge and thus are blind to the electromagnetic and the strong interaction and cannot be bound. In 1920s, while Prof. Satyendra Nath Bose was working in Decca University, he employed new statistical methods for counting of photon. . 61 : CDS 2021-I He sent his paper to Albert Einstein who recognized the value of his calculation, got it translated and published in a renowned German journal of Physics. . Ultimately, all the fundamental particles were classified into two categories A) “Fermions” after Italian scientist Enrico Fermi, and B) “Bosons” after Indian scientist Prof. Bose.
