Currently Playing: The Standard Model - Particle Physics Reactions Part 1/3 (High School Physics)

Particles are the Lego bricks of nature. Their interaction with each other constructs all matter that is present in our universe. Particle Physics studies how particles interact with each other. But before we explore how particles interact, we need to examine the particles which compose the standard model of particle physics. This is the objective of this first section: a reminder of the standard model of particle physics. This video (Part 1/3) presents the elementary particles (fermions, like quarks and leptons, and bosons, like the photon or the gluon). It shows how combining quarks lead to composite particles (hadrons like the proton, the neutron, the pion and the kaon). Antimatter is also discussed. This first video is a brief overview, so if you wish to view a lesson on the standard model of particles with more details and at a slower pace head on to these two videos: Elementary particles: https://youtu.be/guYfayO3ESI Composite particles: https://youtu.be/e-oyDDnI348 - - - - - - - - - - - - - - - - - - - Access to the table of particles: https://www.physics-made-easy.com/Standard-Model-of-Particle-Physics - - - - - - - - - - - - - - - - - - - The full lecture is structured around three videos that follow a general introduction. INTRODUCTION: https://youtu.be/gy-durcAhJ4 SECTION 2: Quantum numbers of particles https://youtu.be/3SVMrLmGHWQ SECTION 3: Conservation laws and particle physics reactions: https://youtu.be/E4JGzQjBgHg -- - - - - - - - - - - - - - - - - - - PART 2 is a detailed look at some of the properties of these particles, which are expressed as quantum numbers (Baryon number, Electric Charge, Lepton number, Strangeness). PART 3: In nature there are some symmetries that need to be respected in all interactions. These lead to the existence of conservation laws (via Noether's theorem). Quantum numbers need to follow these conservation laws. This idea is central. After viewing this section, you will be able to determine if a particle physics reaction is possible or not. For that, we will work on many examples of reactions including Beta decay, muon decay into a positron, and more. This lecture has a lot of information, it’s a real course in itself. I hope you enjoy it and that it helps in giving you a clearer idea about the reactions between particles.
