The Ancient Greek "Computer"

Guest: Lawrence Wilkerson, Retired US Army Colonel, Former Chief of Staff to Secretary of State Colonel Powell, Adjunct Professor of Government and Public Policy, College of William and Mary This afternoon, President Donald Trump did what he’s been promising to do since he took office – pulled the US out of the Iran nuclear agreement, which he called “defective at its core.” In pulling out of the agreement, President Trump says the US will “impose the highest level of economic sanctions” on Iran. The nuclear deal signed in 2015 restricted Iran’s nuclear capabilities in exchange for lifting sanctions that had crippled its economy.

Guest: Bharat Bhushan, PhD, Ohio Eminent Scholar and the Howard D. Winbigler Professor in the Department of Mechanical and Aerospace Engineering If you’ve ever driven in a car with leather seats in the heat of summer, you’ll know the discomfort of sticky leather seats. Not to mention, they stain really easily. Professor Bharat Bhushan has created a special elixir in his engineering lab at The Ohio State University. It’s a liquid coating he sprays on fake leather to make it super-water-proof, self-cleaning, and less sticky when it’s hot outside.

Guest: Calvin Lai, PhD, Assistant Professor of Psychological & Brain Sciences, Washington University in St. Louis On Tuesday, May 29, all the standalone Starbucks stores in the country will close for a few hours in the afternoon “for a mandatory training around unconscious bias.” That announcement came from Starbucks CEO Kevin Johnson a few days after a manager in a Philadelphia Starbucks called police on two black men who were waiting for a friend but hadn’t ordered anything. Video of the men being arrested by police went viral, prompting national outrage and an apology from Starbucks. But what’s this “unconscious bias” training the company’s baristas will now be required to take? And what difference might it make?

Guest: Anders Winroth, PhD, Birgit Baldwin Professor of History at Yale University, Author of “The Age of the Vikings” At the start of the year, an amateur archaeologist and his 13-year-old student were metal detecting on an island in the Baltic Sea in northern Germany. They found what they thought was just some aluminum. But it turned out to be silver – a stash, in fact, of Viking treasure with historical significance tied to an ancient king.

Guest: Theresa Raymond, Closed Caption Coordinator, BYUtv Have you ever wondered how closed captioning works? Is someone sitting at a keyboard at that very moment typing the words you see on the screen? Theresa Raymond of BYUtv happens to work in the same building, so we brought her over to give us an inside look at how it works. We started with the most intense part of her team’s job – doing captions for live television shows like BYU SportsNation which airs weekdays at noon Eastern on BYUtv.
