In this episode of pplpod, we explore the extraordinary life of Dorothy Hodgkin, the Nobel Prize-winning chemist who transformed medicine by revealing the hidden atomic structures behind penicillin, vitamin B12, and insulin. Battling severe rheumatoid arthritis that left her hands permanently deformed, Hodgkin continued working in the laboratory by strapping custom-built levers to scientific equipment so she could keep operating her X-ray machines.

This episode breaks down the mind-bending science of X-ray crystallography through vivid analogies like the “invisible chandelier,” showing how Hodgkin used scattered diffraction patterns to reconstruct the three-dimensional architecture of life-saving molecules. We examine how her discoveries helped unlock the mass production of penicillin during World War II, revolutionized the treatment of ane ...
