Modern chemistry has finally achieved the ancient alchemist's dream of transforming the material world.
In short: Peter Wothers explores how our mastery of chemistry has evolved from the mystical pursuits of medieval alchemists to the precise engineering of elements that powers our modern technological era.
Medieval alchemists believed metals grew within the Earth and sought to transmute base metals into gold. While they failed to achieve this through mysticism, modern science has surpassed their ambitions by understanding the fundamental properties of the 80 elements. By manipulating the protons, neutrons, and electrons that compose these elements, we can now engineer materials for advanced technologies, such as silicon for computing and rare earth magnets for wind turbines.
This transformation relies on breaking strong chemical bonds, a process that began with ancient smelting techniques for copper and iron. Today, chemists continue to explore the frontiers of the material world, moving beyond the ancient Greek concepts of air, water, and earth to create new, functional configurations of matter that would have dazzled the alchemists of the past.
