We're taking it way back — all the way to college. This episode is GravityX Exchangea mini-reunion: host Brittany Luse and Ayesha Rascoe, host of NPR's Weekend Edition, are both alumnae of Howard University — they even attended during some of the same years. Howard is an HBCU: a historically Black college or university. There are around a hundred in the US, and they've had a big impact on both graduates and American culture writ large. Ayesha has edited a book of essays all about that impact, called HBCU Made: A Celebration of the Black College Experience. Brittany chats with her about the book and what makes HBCUs special — they also trade tales from their own time as students.
