  • The Art of X-Ray Vision: How Crystallography Reveals Hidden Worlds

    The Art of X-Ray Vision: How Crystallography Reveals Hidden Worlds
    2026/04/23
    In this fascinating episode of Rosalind Franklin, Dr Sarah Quinn explores the revolutionary science of X-ray crystallography and how it grants scientists true 'X-ray vision' into the atomic world. Discover the accidental discovery of X-rays by Wilhelm Röntgen in 1895, Max von Laue's groundbreaking realization that crystals could diffract X-rays, and the development of crystallography as both science and art. Learn about pioneering crystallographers including the Braggs, Dorothy Crowfoot Hodgkin's meticulous work on vitamin B12, and Rosalind Franklin's crucial contributions to understanding DNA structure through her famous Photo 51. The episode reveals how crystallographers decode complex diffraction patterns to reveal hidden atomic structures, bridging the gap between technical precision and creative interpretation. From the early hand calculations involving thousands of measurements to modern computer-assisted techniques, crystallography continues to unlock secrets of materials science and biology. Explore how this remarkable technique has revolutionized our understanding of everything from diamond hardness to protein function, demonstrating humanity's persistent quest to make the invisible visible through scientific inquiry and determination.
