The 9th lecture (in Hindi) in the Umang Library popular science series will happen this Sunday, December 13, at 5 PM IST. The series is aimed at creating awareness about science in the Hindi belt of India.

Abstract : From the Electron to the Higgs: The Long Twentieth Century of Particle Physics

In 1897 J J Thomson discovered the electron with a Cathode Ray Tube that could fit on a small table in his Cavendish Laboratory. In 2012 the Higgs particle was discovered at the Large Hadron Collider which is the largest scientific instrument ever built (it is a particle accelerator that sits in a tunnel 27 kilometres in circumference and required billions of dollars to build). If the 1897 discovery inaugurated particle physics, the 2012 one was the culmination of the chain of stunning discoveries of new particles spread across these 115 years. In this lecture we will tell the story of the major landmarks of this long century of particle physics which include discoveries of the proton, of anti-particles and of quarks. This is the epic story of the eternal quest of humankind for the most fundamental laws of Nature and the most fundamental constituents of matter. Like all the lectures in this series this lecture too will be accessible to high school students and to curious lay persons.
