What strange forces saved one isolated section along the Upper Mississippi River from the repeated crushing and scouring effects of glaciers during the last two million years? And what pre-Ice Age throwbacks survived here in this unique geologic refuge that holds more Native American effigy mounds, petroglyph caves, strange geological features, and rare species than anywhere in the Midwest? These questions and more are answered in this captivating new documentary. A team of scientists embarks on a journey of exploration to expose both the science and threats behind three unique features of the zone - rare plants and animals, odd geological phenomenon, and striking remnants of a Native American pilgrimage like no other.

Travel alongside the astronauts as they deploy and repair the Hubble Space Telescope, soar above Venus and Mars, and find proof of new planets and the possibility of other life forming around distant stars.

This film is a treasure. It's one of the best examples of the theory and practice of the art of camouflaging military targets from air observation & attack that you'll find anywhere, presented in a highly entertaining Disney style full color animation supplemented by live action film. Hosted by “Yehudi the Chameleon,” the action is centered around a P-39 Airacobra base in the Pacific and is chocked full of useful information & “how-tos.” Some of the many things you'll learn: how camouflage works in Nature, analyzing the specific camouflage needs of your location, theories and application of different camouflages, hiding in shadow, using camouflage netting, creating dummy targets, breaking up distinctive shadow lines that outline structures, concealment by “blending,” making “trees,” hiding routes & paths or creating fake ones, hiding targets in plain sight by adding minimal camouflage and more.

Animated training film demonstrating the process by which an autopilot uses gyroscopic controls to maintain an airplane in level flight.

Concern over global climate change may be at an all-time high, but climate change is nothing new - the earth's climate always followed natural cycles of warming and cooling. In Unstoppable Solar Cycles, Dr. Willie Soon and Dr. David Legates challenge the popular idea that human-generated CO2, is causing catastrophic global warming. These scientists propose an alterantive theory - that the current warming has more to do with solar activity than with human activity.
