Ben Zimmer (the "On Language" columnist for The New York Times Magazine) sets the wheels in motion with some cautionary newsroom tales: attempts to avoid human error lead to editorial absurdities no one saw coming. Then, a Harvard psychologist eager to safeguard Cold War troops from brainwashing creates an experiment (described as "stressful interrogation") to weed out unfit candidates. But the experiment takes a toll on a shy undergrad…who goes on to become a notorious terrorist. Professor Ruben Gur and writer Alston Chase shed some light on the story. Next, we're off to Wheeler Peak, Nevada--the home of the Bristlecone Pine. Nature writer Michael Cohen and reporter Pat Walters tell the story of Don Currey, a scientist whose tool malfunction unwittingly led to the death of the world’s oldest tree. Ron Lanner, a retired forest service scientist helps describe the scene, and Robert and Pat debate the value of such an old tree.
