Comfortable people don't invent things. René Laennec was very, very uncomfortable.

A painfully shy doctor in 1816 had to put his ear on a patient's bare chest in front of a packed amphitheater, and he couldn't bring himself to do it. What he grabbed instead is still hanging around your doctor's neck today.

In this episode of Proof of Concept, Jessica O. Matthews tells the story of René Laennec and the invention of the stethoscope. She breaks down how doctors listened to the body before it and the simple science that made a rolled-up stack of paper work better than a bare ear. Then she shows you how to build your own at home and makes the case that the most uncomfortable person in the room is often the one who invents a better way.

Topics covered:

• How a shy doctor invented the stethoscope in 1816
• Why sound travels better through solids than air
• Why discomfort is a signal worth listening to as an inventor
