How do plants turn sunlight into energy? A Nobel laureate explains the process.
In short: In this 1976 lecture, Nobel Prize-winning chemist Sir George Porter explores the fundamental link between sunlight, food, and energy. Through a series of engaging demonstrations, he reveals how plants harness light to fuel photosynthesis and how catalysts facilitate these essential biological reactions.
Recorded on December 3, 1976, as part of the Royal Institution Christmas Lectures, this presentation by Sir George Porter investigates the power of sunbeams. Porter, a former Director of the Royal Institution and Baron of Luddenham, uses a variety of experiments to illustrate how light stimulates life and provides energy.
The lecture features a practical demonstration using a cake to explain how humans derive energy from food, alongside experiments showcasing photosynthesis. Porter also examines the role of catalysts in chemical processes and provides a fascinating look at the phenomenon of 'cold light' produced by female fireflies.
