We look at scientists who learned to manipulate common materials such as steel, glass and silicon, and how their inventions shaped the human experience.

Our guest is scientist, storyteller and science writer, Ainissa Ramirez, author of the new book, "The Alchemy of Us, How Humans and Matter Transformed One Another."

We discuss the wonder of science, especially material science: What it is and why it’s a crucial part of all that is in us and around us.
