A World War II bomb destroyed a London lab where a PhD student was measuring the viscosity of hot water, and it freed one of the 20th century’s most restless minds. This deep dive follows the physicist who switched to biology at 31 after reading Erwin Schrödinger’s What Is Life?, teamed up with James Watson at Cambridge’s Cavendish Laboratory, and helped transform biology into a science of information and molecular machinery.

The episode explains how Chargaff’s rules, base pairing and Rosalind Franklin’s X-ray data, including Photo 51, led to the 1953 double helix model, and examines the controversy over how her work was obtained and credited. It then covers the genetic code, adapter molecules, the central dogma, a late-career move to the Salk Institute to study consciousness, and the highly controversial views and allegations that complicate his legacy.

• How “physicist’s hubris” and a talent for synthesizing other people’s data helped beat Linus Pauling to the structure of DNA
• Why the first inside-out DNA model failed and how purine-pyrimidine pairing produces a uniform helix
• The three ways Rosalind Franklin’s data reached Cambridge and why her contribution was marginalized for decades
• Messenger RNA, transfer RNA, triplet codons and the central dogma that information flows from DNA to RNA to protein
• The search for the neural correlates of consciousness, including 40 Hertz oscillations and the claustrum, plus directed panspermia and eugenics views
