  • Beyond the Telescope: Newton's Secret Obsessions with Alchemy and Theology

    Beyond the Telescope: Newton's Secret Obsessions with Alchemy and Theology
    2026/05/21
    Discover the hidden side of Sir Isaac Newton in this fascinating exploration of his secret passions for alchemy and theology. While Newton is celebrated for his groundbreaking work in physics and mathematics, he actually spent more time studying chemical transformations and biblical prophecy than developing scientific theories. Dr Sarah Quinn reveals how Newton's alchemical experiments in his Cambridge rooms led him to seek divine forces animating matter, while his extensive theological studies resulted in controversial anti-Trinitarian beliefs and predictions about the world's end in 2060. Learn why Newton kept these pursuits secret, how they actually informed his scientific work, and why his heirs tried to suppress these manuscripts after his death. This episode examines the interconnected worldview of a complex genius who saw alchemy, theology, and physics as complementary paths to understanding God's creation. Featuring insights into Newton's coded writings, his rejection of the Trinity doctrine, and how economist John Maynard Keynes later called him 'the last of the magicians.' Perfect for history enthusiasts, science lovers, and anyone curious about the hidden depths of one of history's greatest minds.

  • Seeing the Light: Newton's Groundbreaking Work in Optics and Color Theory

    Seeing the Light: Newton's Groundbreaking Work in Optics and Color Theory
    2026/05/07
    Explore Isaac Newton's revolutionary discoveries in optics and color theory in this fascinating episode of the Isaac Newton podcast. Dr Sarah Quinn examines how young Newton's experiments with prisms during the 1660s plague years completely overturned centuries of accepted wisdom about light and color. Learn about Newton's famous 'crucial experiment' that proved white light contains all colors of the spectrum, his invention of the reflecting telescope that solved chromatic aberration problems, and his observations of interference patterns now known as Newton's rings. This episode reveals how Newton's methodical experimental approach challenged the Aristotelian view that white light was pure, instead demonstrating it was a complex mixture of all colors. Discover how his work with dispersion explained natural phenomena like rainbows and laid groundwork for modern understanding of light's wave-particle duality. From his tiny six-inch reflecting telescope that revolutionized astronomy to color theory insights that influenced artists, Newton's optical discoveries continue impacting technology today.
