Hosted by Lester Nare and Krishna Choudhary, this episode tells the story of Nobel laureate Chen Ning Yang and how his ideas on symmetry and gauge theory transformed modern physics. Summary• Early Years &amp; Mentorship: From China to Chicago — learning under Fermi and Chandrasekhar.• Parity Violation: How Yang &amp; Lee overturned the mirror-symmetry assumption and changed physics forever.• Gauge Symmetry &amp; Yang-Mills Fields: The foundation of the Standard Model of particle physics.• Legacy &amp; Philosophy: Why Yang saw beauty as nature’s signature and symmetry as its language.

AI-Generated Genomes, Retinal Implants, and Palomar’s Mystery Lights Explained (EP. 15)

From First Principles is a fast, funny, and rigorous breakdown of the biggest science stories of the week, hosted by Lester Nare and physicist Krishna Choudhary, PhD. We go past headlines into the actual mechanics: what happened, why it matters, and what everyone’s missing.

Expect physics, space, AI, energy, biotech, and the occasional “wait… is that real?” story. If you’re curious, skeptical, and you like learning in public — you’re in the right place.
