Your Inner Fish

What if there was a museum that contained every type of life form in the universe? This experience takes you on a tour through the possible forms alien life might take, from the eerily familiar to the utterly exotic, ranging from the inside of the Earth to the most hostile corners of the universe. New research is upending our idea of life and where it could be hiding: not just on Earth-like planets, where beings could mimic what our planet has produced, but in far flung places like the hearts of dead stars and the rings of gas giant planets. Nowhere in the universe is off limits. Only when we know what else is out there will we truly know ourselves. This thought experiment will give us a glimpse into what could be out there, how we might find it, and just how far nature’s imagination might stretch.

Fascinating - and unintentionally funny - experiments at Austria's famed Institute for Experimental Psychology involve a subject who for several weeks wears special glasses that reverse right and left and up and down. Unexpectedly, these macabre and somehow surrealist experiments reveal that our perception of these aspects of vision is not of an optical nature and cannot be relied on, while the unfortunate, Kafkaesque subject stubbornly struggles through a morass of continuous failures.

Thirty distinguished astronomers are visited at their observatories throughout the world in this comprehensive report of astronomical theories, research, and discoveries.

A documentary on Al Gore's campaign to make the issue of global warming a recognized problem worldwide.

Physicist Dr Helen Czerski takes us on a journey into the science of bubbles - not just fun toys, but also powerful tools that push back the boundaries of science.

What caused Building 7 to collapse on 9/11? Dr. Leroy Hulsey from the University of Alaska Fairbanks may have the answer, following an exhausting four year engineering study.

Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand. It turns out that chaos theory answers a question that mankind has asked for millennia - how did we get here?

With Pete Smith providing dry off-screen commentary, we watch some serious fishing: a marlin caught near Catalina, a hammerhead shark caught then wrestled in a small rowboat near Baja, the largest (721 pounds) great white shark caught to date in California waters, Chinook Indians catching salmon at Celilo Falls in Oregon - each with his designated place on the river where his ancestors stood, and, last, a crew on a boat off Mexico hoisting and hurling tuna using unbarbed hooks (baited only with a feather) as fast as they can as long as the school is there - backbreaking work - but a $25,000 catch.

A dive inside a wild land where nature hides some of her greatest secrets: The Alps. Steep slopes, wind swept cutting edge rocks. An air desperately lacking of oxygen. A biting cold. How do living beings adapt to those extreme conditions?
