Stuff You Missed in History Class

This 2012 episode from previous hosts Sarah and Deblina explores the rivalry between paleontologists Edward Drinker Cope and Othniel Charles Marsh. The two started out as friends, but their friendship soon soured.See omnystudio.com/listener for privacy information.

Holly and Tracy share experiences with MRIs and hospital stays, and also talk about the various disagreements and biases in play in the medical community when giving attribution for the invention of the MRI.See omnystudio.com/listener for privacy information.

Once Dr. Ray Damadian had the idea to create a machine that used nuclear magnetic resonance to capture diagnostic data by scanning a human body, he still had to build it. And though he did, other scientists got credit for inventing the MRI.   Research: Bashir U, Rock P, Murphy A, et al. T2 relaxation.
