In the latest episode of Penn Today’s “Office Hours” podcast Doug Jerolmack, professor of Earth and Environmental Science with a secondary appointment in Mechanical Engineering and Applied Mechanics, discusses the “science of scenery.” 

He talks rounded pebbles along riversides, studying sand movement even as it’s apparently undisturbed, and also teases out the dynamic with his twin brother, who also studies the environment, and the status of his wife’s West Philadelphia taco shop.
