The current Radiolab podcast (and possibly the broadcast) is titled "The
Fact of the Matter" and contains several stories on the meaning of truth.
The second segment is a mind-blowing segment about the "yellow rain" that
the Hmong tribe of Vietnam say killed entire villages. The U.S. blamed the
Soviet Union. The truth is very strange and calls into question: What
happens when three mutually exclusive things are true at the same time,
especially if you have hinged your entire life experience on a truth that
may be false? http://www.radiolab.org I'm not sure of the air schedule,
but Radiolab airs on KALW 91.7 and KQED Radio 88.5.
