Episode 5: Riding With Strangers

Transportation matters. When people need to get places, but don’t have a good way to do so, it’s more than just a drag for them – it’s also a drag for the economy. Americans are living increasingly far from their places of employment, which knocks walking or biking out of the way for many. And not everyone has a car to get themselves from place to place (and even if they did, the cost to the environment would be pretty steep). Moreover, public transportation in U.S. cities, in particular, does not always serve all city residents equitably.

Of course, there’s always…carpooling.

In this episode, Anna and Annie discuss the efficiency of ride sharing, the topic of a recent paper, “Scaling Law of Urban Ride Sharing,” authored by this episode’s guest Steven Strogatz, professor of applied mathematics at Cornell University, along with several colleagues: Remi Tachet, Oleguer Sagarra, Paolo Santi, Giovanni Resta, Michael Szell, and Carlo Ratti, the director for MIT’s Senseable City Lab. Listen in, and get ready to change your Lyft settings to “Line”.

Episode 1: Racism and Segregation

Racism and Segregation

In Racism and Segregation, Anna and Annie call on two people whose online contributions have helped paint a picture of racism and segregation in this country.

Dustin Cable’s work on the Racial Dot Map paints this picture in a nearly literal way; see what we mean here.  Also, check out his methodology and code, and see one source of his inspiration–the work of Brandon Martin-Anderson and Peter Richardson–here.

Nicky Case and collaborator Vi Hart created a playable blog post called Parable of the Polygons earlier this year.  This interactive site demonstrates the Nobel Prize-winning work of Thomas Schelling–work that concludes that small individual bias may be responsible for the neighborhood segregation we see so clearly in the Racial Dot Map.

Want to understand how math can help us better understand bias, racism, and segregation in this country?  Listen to Episode 1: Racism and Segregation now.
