Soundwaves: The Symphony of Physics
Sound is one of the most vivid ways we interact with the underlying science of the universe. A sound can make us laugh, cry or cower in fear, but it can also help us understand our world, how it works and what it's made of. Sound is something we all take for granted, but, in fact, when you hear something you're listening to the sound of pure physics. In this engrossing two-part series Helen Czerski goes on a spectacular journey into the world of sound to discover what it is and what it reveals about the fundamental forces of nature.
