In this episode of the 632nm podcast, Scott Aaronson shares his early fascination with calculus at age 11 and how “rediscovering” old mathematics led him toward groundbreaking work in complexity theory. He gives a lucid explanation of P vs NP, revealing how seemingly trivial questions about verifying solutions speak to some of the deepest unsolved problems in all of computing.

Aaronson also explores the frontiers of quantum computing, from the nuances of quantum supremacy experiments to the idea of quantum money and certified randomness. He explains how amplitudes—rather than straightforward probabilities—unlock powerful interference effects, yet still face limits imposed by measurement. The conversation concludes with a look at the future of fault-tolerant quantum computers and the possibility that we’ve finally reached the ultimate horizon of computability—unless nature has even stranger surprises in store.

In this episode of the 632nm podcast, we explore cutting-edge ideas in epigenetics and academic publishing. Oded Rechavi reveals how C. elegans worms defy conventional genetics by passing on traits through small RNAs, and discusses how these mechanisms might reshape our understanding of heredity. We also hear about a remarkable experiment hijacking Toxoplasma gondii—the so-called “cat parasite”—to deliver proteins into the brain, opening possible routes for new therapies.

Beyond the lab, we explore problems with modern publishing, from glacial review timelines to flawed incentives that push quantity over quality. Learn how AI-driven solutions might speed up peer review, allow scientists to focus on what truly matters, and help keep the spark of curiosity alive.

In this episode of the 632nm podcast, we explore how diamond-based nitrogen vacancy (NV) centers went from being a curiosity in gemstone physics to a transformative tool for precision magnetometry. You’ll hear how these tiny defects enable room-temperature quantum sensing, providing ultra-high spatial resolution and remarkable resilience in extreme conditions—from planetary research unlocking secrets of our solar system’s earliest days to potential biomedical diagnostics. Our guest recounts the serendipitous connections, engineering challenges, and surprising scientific discoveries along the way.

We also discuss how interdisciplinary collaborations spark new ideas, how startups and academia differ in their pursuit of quantum breakthroughs, and why community-driven science can accelerate major scientific leaps.
