On the box, Wednesday March 12

Not to miss tonight at 7pm on PBS: American Masters, Pete Seeger: The Power of Song

Feeling science-y? Knowledge Network has100 Greatest Discoveries of Physics on at 8pm. I believe it's hosted by Bill Nye. What value: you get 100 of them in just 1 hour.

Over on OLC they have two back to back Pilot Guides: South Africa and Lesotho at 7:30pm and American Civil War at 8pm. Nice little 30 minute shots.

At 10pm the Knowledge Network has For King and Country Passing the Torch: Canadians Go to War 1939 - 1941

Also at 10 is Turning Points of History Great Atlantic Air Race on History Television.

Doesn't seem to be anything on for the night owls, unless the Osmonds 5oth is for you.
