Explains that heat is really a form of motion, a form of kinetic energy and that it can be converted to other forms of energy and transferred through conduction, convection and radiation. Shows practical examples in which heat preserves lives and makes daily living more convenient.
Ever heard of the Thorium molten salt reactor? That's hardly surprising, as for 70 years, it has been inexplicably kept under wraps by the nuclear industry, despite the fact it could revolutionise energy production. It offers the promise of nuclear energy without waste and without danger. The "green atom": fact or fiction? Research that was dropped without explanation in 1973, has now become a topic of lively discussion...
One entry in a series of films produced to make science accessible to the masses—especially children—this film describes the sun in scientific but entertaining terms.
A documentary of insect life in meadows and ponds, using incredible close-ups, slow motion, and time-lapse photography. It includes bees collecting nectar, ladybugs eating mites, snails mating, spiders wrapping their catch, a scarab beetle relentlessly pushing its ball of dung uphill, endless lines of caterpillars, an underwater spider creating an air bubble to live in, and a mosquito hatching.
Éclipse 73
For more than 50 years, we’ve been unsuccessfully searching for any evidence of intelligent extraterrestrial life. But, the discovery of thousands of exoplanets has meant the hope of finding them is higher than ever. If any messages could eventually be decoded and answered in any far, far away star, it could radically transform our consciousness as species and our place in the universe. A message from the stars changes life on Earth… forever.
A unique project, the popular science series "Bread" is shooting around the world, interviews with scientists and world-class experts. There are 4 series in the project: "Immortality", "Money", "Hunger" and "Gene". This is a story about how bread controlled the destinies of continents and empires, how the rise of some civilizations and the fall of others depended on it, how in different countries and at different times it performed the function of money. This is the first time such a complete study of bread and grain is being carried out on a television screen. The focus is on the most interesting events in the history of Russia, Italy, France, Germany, England, China, Egypt and other countries.
Each grain crop - wheat, rye, rice and corn - has been "creating" a special type of person for centuries. For example, rye formed the Slavic culture, wheat influenced the inhabitants of almost all of Central Europe and a significant part of Asia, corn formed the inhabitants from Mexico to Nicaragua, and rice - representatives of Japan, India and China. Today, genetic engineers are trying to create the bread of the future. It is likely that after some time we will have three-dimensional food printers in our kitchens that will be able to "print" buns, loaves or confectionery. However, scientists are convinced that only part of the components for the "printer" will be chemical, and the rest of the components will continue to be grown on earth. At the same time, some researchers believe that genetic engineering may turn out to be a "Pandora's box", while others are sure that they can no longer do without it.
Thirteen years since the Fukushima Daiichi nuclear accident, the government's plan to decommission the plant is at a crossroads. We take a close look at the efforts to secure Fukushima's future.
A vivid journey into the mysterious subterranean world of mycelium and its fruit— the mushroom. A story that begins 3.5 billion years ago, fungi makes the soil that supports life, connecting vast systems of roots from plants and trees all over the planet, like an underground Internet. Through the eyes of renowned mycologist Paul Stamets, professor of forest ecology Suzanne Simard, best selling author Michael Pollan, food naturalist Eugenia Bone and others, we experience the power, beauty and complexity of the fungi kingdom.
If machines can be smarter than people, is humanity really anything special?
Computer animation and footage from NASA space missions explain how our solar system evolved and the place Earth has within the system.
Bill Nye is retiring his kid show act in a bid to become more like his late professor, astronomer Carl Sagan. Sagan dreamed of launching a spacecraft that could revolutionize interplanetary exploration. Bill sets out to accomplish Sagan's mission, but he is pulled away when he is challenged by evolution and climate change contrarians to defend the scientific consensus. Can Bill show the world why science matters in a culture increasingly indifferent to evidence?
Ben Fogle spends a week living inside the Chernobyl Exclusion Zone, gaining privileged access to the doomed Control Room 4 where the disaster first began to unfold.
The climate crisis, Germany’s nuclear phase-out and Russia’s war against Ukraine are just three of the heavy pieces in the dramatic game about the future of energy. A game with global and unpredictable consequences far beyond where the electricity will be coming from tomorrow. And in the middle of the game we find two small European towns with barely a thousand inhabitants each. Gundremmingen in Bavaria is located around a deactivated nuclear power plant, while the small Polish town of Choczewo will open its first nuclear power plant in 2033. What do the good people on the ground think about it all?
The recent discovery by the Kepler satellite of thousands of Earth-like planets where life could be possible, has given a big boost to the Search for Extraterrestrial Intelligence (SETI). In 2011, for the first time ever, Kepler provided us with a census of the Milky Way. We can now calculate how many stars in the Milky Way could have a planet like ours: around a billion.
Dr. Helen Caldicott is the most prominent anti-nuclear activist in the world. She's been featured on CNN, 60 Minutes, CBC and Democracy Now. In the 80s, Helen Caldicott campaigned against nuclear weapons testing in the pacific (still responsible today for the majority of tritium we're exposed to), and against the notion of a winnable nuclear war. She was nominated for a Nobel Peace Prize for her efforts. She has always made inaccurate statements regarding civilian nuclear power. But, since the Fukushima-Diachii radiation release has caused (and is projected to cause) zero fatalities... http://www.unis.unvienna.org/unis/en/... ...her tone has changed when speaking to supporters. This has not been acknowledged by prime-time media, as they continue to use her as a source. Any person or media outlet should check Caldicott's history of statements (on any subject) against a domain expert before using her as a source.
A film which explores a radical new idea - is there an imbalance between our brain hemispheres that is affecting how we live in our modern society?
A documentary produced in 1979 to celebrate the centenary of the birth of Albert Einstein. Narrated and hosted by Peter Ustinov and written by Nigel Calder.
Like almost all children, Celeste is fascinated by dinosaurs. She is preparing a talk for her class about how they went extinct when Moon, a very wise and magical character, poses a tantalizing question: What if I told you that there are still dinosaurs among us? Celeste will join Moon on a journey through time, an exciting adventure that will show them the Earth as it was in the very, very distant past. They will see the fascinating transformations that these animals underwent over millions of years, creating giant creatures, armored beasts, and super-predators, until the day that a cataclysmic impact event caused a mass extinction on Earth. But all is not lost. Celeste will discover the key to their survival.
