Episode 62: Chemical Romance
Chemical Romance. Uploaded to istock by user Nicole Cioe.
It’s Valentine’s Day this weekend, and love is in the air. We won’t even bother trying to understand the laws of human attraction. Instead let’s learn how atoms find each other with an examination of chemical bonds. We chat with Alan Rocke, Henry Eldridge Bourne Professor of History at Case Western Reserve University. Rocke enlightens us on past scientific theories on the ways that materials joined in molecular union. And we examine ozone. Until recently, humans did not fully understand our own powers of destruction when it came to this important molecule made up of three oxygen atoms. Chemical Agent: Free Radicals.
