From First Principles
Podcast Description
We break down the week’s biggest science headlines from first principles—because understanding the world shouldn’t require a PhD.
Podcast Insights
Content Themes
The show focuses on breaking down complex scientific topics from first principles, with episodes covering themes such as cosmic discoveries, advancements in biotechnology, and notable astronomical events. Recent episodes have explored subjects like the characteristics of the interstellar visitor 3I ATLAS, the capabilities of the Vera Rubin Observatory, and the implications of CRISPR advancements.

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.
Hosted by Lester Nare and Krishna Choudhary, this Season Finale closes out Season 1 with a deep dive into the physics behind fusion’s biggest bottleneck: fast magnetic reconnection. We unpack why classic models predicted reconnection should be slow, why nature (and tokamaks) disagree, and how modern “plasmoid” reconnection helps explain solar flares, plasma instabilities, and the real engineering challenges fusion reactors face. Then we run a full Season 1 recap — our favorite episodes, biggest scientific moments, and the corrections and lessons we’re taking into Season 2.
Summary
- Fusion’s biggest problem — magnetic reconnection, why the Sweet–Parker model breaks down at scale, and how plasmoid instability enables fast reconnection.
- From the Sun to tokamaks — how reconnection drives solar flares, space weather, and plasma confinement limits in fusion devices.
- Season 1 leaderboard — our top episodes and the breakthroughs that stuck: astronomy, biology, AI, quantum, and the history of science.
- Corrections + what’s next — what we fixed, what we learned, and how Season 2 evolves the format.
