To the majority of humankind, rocks may appear to be static, timeless objects, but not to the geologist Marcia Bjornerud. In her mind, rocks are rich pieces of text that have evolved (and continue to evolve) across millennia, and are therefore incredibly timeful. “They almost demand reading,” Bjornerud says on this episode of Time Sensitive. “You have the feeling that you’re communicating with some larger, wilder, more ancient wisdom.” A two-time Senior Fulbright Scholar, a professor of geology at Lawrence University in Wisconsin, and an expert on the geophysics of earthquakes and mountain building, Bjornerud serves as a sort of geological translator of these “texts,” reading their encrypted messages and stories—tracing their etymologies, essentially—and from there inferring why things are the way they are. Bjornerud’s translations shine across her four books, including the newly published Turning to Stone: Discovering the Subtle Wisdom of Rocks.

On the episode, she discusses the power of looking at the world through a Deep Time lens, why we’re currently in what she considers a “golden age” of geoscience, and what a “time literate” society would mean for humanity and the planet.

Cardiac Cowboys

Cardiac Cowboys

The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
