How Small Is It 04 Elementary Particles (4 K)

Text Music free version website Wiki page In this segment of our How small is it video book, we introduce elementary particles. We start with a description of cosmic rays and gamma rays. They collide with atoms in the atmosphere to create a wide variety of particles. We cover how cloud chambers work to see these new particles. That includes taking a look at the tracks for electrons and protons. We then take a look at the new particles we found on mountain tops and up in balloons: positrons, electronpositron pair creation, muons; pions; kaons; and particle decay timing and signatures. We then cover the hardtofind neutrino, starting with the Ellis Wooster experiment to measure the energy of radium decay into polonium that led to Wolfgang
