Umbrella Progress on a Crowded Sidewalk (podcast #96)

What happens when lots of people with umbrellas walk in opposite directions on a crowded sidewalk? A research study explores that very question, and we explore that study, in this week’s Improbable Research podcast. SUBSCRIBE on Play.it, iTunes, or Spotify to get a new episode every week, free. This week, Marc Abrahams discusses a published lotsa-people-walking-with-umbrellas study. Melissa Franklin, a Harvard physics professor who designed parts of the Large […]
