Science Night 12/23

This week, Science Night celebrates the holidays with two programs in line with the season. First, Nature takes viewers to Alaska for a look into the intimate home of the snowy owl family. Then, NOVA dedicates its program to the hidden formulas of historic cathedrals.

Nature Magic of the Snowy Owl at 7 p.m.

Filmmakers take us deep into the snowy owl’s tundra home on the North Slope of Alaska to observe the daily struggles involved in raising a family of helpless owlets until they’re able to fly. Magic of the Snowy Owl premiered Wednesday, October 24, 2012.

NOVA Building The Great Cathedrals at 8 p.m.

Carved from 100 million pounds of stone, soaring effortlessly atop a spiderweb of masonry, Gothic cathedrals are marvels of human achievement and artistry. But how did medieval builders reach such spectacular heights ?Consuming the labor of entire towns, sometimes taking 100 years to build, these architectural marvels were crafted from just hand tools and stone. Many now teeter on the brink of catastrophic collapse. To save them, an international team of engineers, architects, art historians and computer scientists searches the naves, bays, and bell towers for clues to how the dream of these heavenly temples on earth came true. This program reveals the hidden formulas, drawn from the pages of the Bible itself, that drove medieval builders ever upward.
