Most shows in the U.S. are repeating today, due to the holiday. Some are in repeats all week. Of those repeats, theoretical physicist Michio Kaku is on Conan tonight, and bear biologist Chris Morgan will appear with David Letterman on Friday.
For the new episodes, Adam Savage visits with Craig Tuesday night. His usual television companion, Jamie Hyneman, is not listed, so this segment may edge into Savage’s non-MythBuster work. Savage was recently featured on PBS’s NewsHour at a Maker Faire, which emphasizes grass roots innovation.
