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 episode is a deep dive into one of the strangest and most hard-fought materials science stories in decades: the claim that researchers have finally synthesized bulk hexagonal diamond, also known as lonsdaleite. They break down why this material matters, how it differs from ordinary cubic diamond, why scientists argued about its existence for more than 50 years, and what the new Nature paper actually did to convince skeptical reviewers.
Summary
Why hexagonal diamond matters — if real, it is a long-sought carbon phase that could be slightly harder than conventional diamond and useful in extreme industrial settings.
The first-principles chemistry — carbon allotropes, x-ray crystallography, cubic diamond, and the ABAB stacking that makes hexagonal diamond different.
The experimental breakthrough — how the new team engineered around the default pathway to ordinary diamond by controlling graphite orientation and pressure direction.
The controversy — why the peer review was intense, and how the new paper relates to an earlier 2025 Nature paper with a similar claim.
