"Cyberchase" (PBS, 2:30-3pm E/P on some stations, also 3-3:30 E/P -- check
local listings) The topic of this lively animated program about math is
"symmetry". And you'll find out lots about it when the villain on the program
(called "Hacker") steals and reprograms a machine that had been making
everything cyberspace symmetrical. He threatens to make everything tilted and
unbalanced and disagreeable to look at. The kids in the show must master the
properties of symmetry, which are hidden in many objects, to restore a sense
of pleasing regularity in the world.
"Blizzards" (History Channel, 4:30-5pm E/P) Here's a short, rather
frightening documentary in a series called "Wrath Of God" which describes a
blizzard in 1888 that was so severe that it completely paralyzed mighty New
York City and, in Nebraska earned the name "The School Children's Blizzard"
because its victims were trapped and some perished in their one-room
schoolhouses. (It's one of the reasons that, nowadays, they tell you to stay
home when there's a blizzard.)
