She teaches all about quantum physics in a fun and simple way. Quantum physics is the study of the smallest things in the universe, and it's one of the most fascinating and important branches of science. But it can also be very confusing, especially for kids. In this podcast, Tanvi explains complex concepts like entanglement, superposition, uncertainty principle and a lot more, in a way that anyone can understand. So whether you're a kid, a parent, or just someone curious about quantum physics, subscribe NOW!","last_synced_at":null,"page_url":"https://stenobird.com/podcast/quantum-physics-for-kids-6713249"},"episode":{"title":"Quantum Electrodynamics and Feynman Diagrams - Deciphering the Secrets of Light and Matter","slug":"quantum-electrodynamics-and-feynman-diagrams-deciphering-the-secrets-of-light-and-matter","published_at":"2024-11-10T17:32:24+00:00","page_url":"https://stenobird.com/podcast/quantum-physics-for-kids-6713249/quantum-electrodynamics-and-feynman-diagrams-deciphering-the-secrets-of-light-and-matter","show_page_url":"https://stenobird.com/podcast/quantum-physics-for-kids-6713249","url":"https://podcasters.spotify.com/pod/show/tanvigopalan/episodes/Quantum-Electrodynamics-and-Feynman-Diagrams---Deciphering-the-Secrets-of-Light-and-Matter-e2qpsfc","audio_url":"https://anchor.fm/s/e9887004/podcast/play/94220204/https%3A%2F%2Fd3ctxlq1ktw2nl.cloudfront.net%2Fstaging%2F2024-10-10%2F389564153-44100-2-eef0cdd98e14e.mp3","summary":"Quantum Electrodynamics (QED) explains how light and matter interact through probability clouds rather than fixed paths.
