Hosted by Lester Nare and Krishna Choudhary, this special episode ranks the 26 scientists shown in Christopher Nolan’s Oppenheimer by one standard only: their contribution to fundamental science. Starting with the Manhattan Project figures near the bottom and working up through the giants of quantum mechanics, relativity, nuclear physics, and logic, the episode turns a movie cast list into a surprisingly deep walk through the history of modern physics.

Summary

A ranking framework that actually means something — this list is based on scientific achievement, not movie prominence, clout, or vibes.

A tour of 20th-century science — from nuclear chain reactions and black holes to MRI, GPS, quantum mechanics, and information theory.

The great debates — several placements are designed to provoke real argument, especially around how Oppenheimer compares to the physicists around him.

A top tier full of monsters — the back half of the episode becomes a speedrun through some of the most influential scientific minds of the modern era.

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.

Hosted by Lester Nare and Krishna Choudhary, this episode is a full deep dive on Artemis II as the crew returns from humanity’s first crewed lunar flyby in more than 50 years. Lester and Krishna break down the mission photo by photo, from launch and translunar injection to Earthset, Earthrise, the in-space solar eclipse, the science of lunar observations, and the skip-entry reentry profile bringing Orion home.

Summary

Why Artemis II is historic, what the crew saw on the far side of the Moon, and why this mission matters for the long-term return to the lunar surface.Why NASA relied on the Nikon D5 for deep-space photography, and what camera physics, low-light performance, and radiation tolerance have to do with getting these images home.The standout observations from the flyby: Earthset, Earthrise, a rare in-space solar eclipse, planetary alignment during eclipse, and the first crewed visual observations of meteoroid impact flashes on the Moon.How Orion’s reentry works, why Artemis II uses skip entry, what happened to Artemis I’s heat shield, and what NASA changed for the crewed return.
