What is the World Made Of?

Michael Mosley takes an informative and ambitious journey exploring how the evolution of scientific understanding is intimately interwoven with society's historical path.

In this episode, Michael demonstrates how our society is built on our search to find the answer to what makes up everything in the material world. This is a story that moves from the secret labs of the alchemists and their search for gold to the creation of the world's first synthetic dye - mauve - and onto the invention of the transistor.

This quest may seem abstract and highly theoretical. Yet it has delivered the greatest impact on humanity. By trying to answer this question, scientists have created theories from elements to atoms, and the strange concepts of quantum physics that underpin our modern, technological world.
