The film discusses the evolution and potential of using light waves, particularly coherent light, for communication. It highlights the development of lasers at Bell Telephone Laboratories, explaining how they produce a highly controlled and intense beam of light that could revolutionize communication. The film emphasizes the vast possibilities of lasers, including applications in telecommunications, surgery, and exploring the universe, suggesting that this technology represents a significant step in humanity's understanding and use of light.

Just outside Paris, France, inside a high-tech vault, requiring three independently controlled keys, rests a small metallic cylinder about the diameter of a golf ball. Encased within three vacuum-sealed bell jars it may not look like much, but it is one of the most important objects on the planet. It affects nearly every aspect of our lives from the moment we are born, to the food we eat, the cars we drive, and even the medicines we take. The Last Artifact follows the high-stakes race to redefine the weight of the world reveals the untold story of one of the most important objects on the planet. The kilogram, the base unit of mass in the International System of Units, helped send humans to the moon and satellites into space. This small hunk of metal is the object against which all others are measured. Yet over time, its mass mysteriously eroded by the weight of an eyelash. A change that, unbeknownst to most, unleashed a crisis with potentially dire consequences.
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?
Is nuclear energy the solution to the climate crisis? Whether it is the only carbon-neutral technology capable of tackling the crisis or a fatally convenient stopgap, time is running out.
A fascinating new look at the biblical, historical, and scientific evidence for Creation and the Flood. Learn from more than a dozen scientists and scholars as they explore the world around us in light of Genesis. Dr. Del Tackett, creator of The Truth Project, hikes through canyons, climbs up mountains, and dives below the sea in an exploration of two competing views... one compelling truth.
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.
When the Tanana River bridge was installed in Salcha, Alaska, the community worried about the levee's effects on fish wildlife. Salcha Elementary School, along with the help of Tanana Valley Watershed Association, conducted a 10-year scientific project with students to study the effects the levee had on Piledriver Slough. Tori Brannan - the filmmaker's mother - is a retired principal at Salcha Elementary and was the project's centerpiece. She shares her experiences with the project, the community, and how her daughter's involvement strengthened their relationship.
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.
The Academy Award® nominee Cosmic Voyage combines live action with state-of-the-art computer-generated imagery to pinpoint where humans fit in our ever-expanding universe. Highlighting this journey is a "cosmic zoom" based on the powers of 10, extending from the Earth to the largest observable structures in the universe, and then back to the subnuclear realm.
If machines can be smarter than people, is humanity really anything special?
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?
Robert McChesney lays the blame for the US's current state of affairs squarely at the doors of the corporate boardrooms of big media, which far from delivering on their promises of more choice and more diversity, have organized a system characterized by a lack of competition, homogenization of opinion and formulaic programming.
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.
Twenty years after A Brief History of Time flummoxed the world with its big numbers and black holes, its author, Stephen Hawking, concedes that the "ultimate theory" he'd believed to be imminent - which would conclusively explain the origins of life, the universe and everything - remains frustratingly elusive. Yet despite his failing health and the seeming impossibility of the task, Hawking is still devoted to his work; an extraordinary drive that's captured here in fleeting interview snippets and footage of the scientist sharing a microwave dinner with some fawning PhD students. Though the pop-science tutorials that dapple the first of this two-part biography are winningly perky, Hawking, alas, remains as tricky to fathom as his boggling quantum whatnots
Before the internet. Before social media. Before breaking news. The victims of Thalidomide had to rely on something even more extraordinary to fight their corner: Investigative journalism. This is the story of how Harold Evans fought and won the battle of his and many other lives.
In Astronomy Part 2, you will learn all about the planets, asteroids, comets, meteoroids, the layers of the sun, fusion, and more. The Standard Deviants make learning astronomy easier with their unique teaching style, which incorporates humor, mnemonics, and sophisticated computer graphics.
This series also covers the essential concepts of astronomy: gravity, the light spectrum, Earth's magnetic field, the solar system, the sun, Kepler's Law, the universal law of gravitation, the Doppler Effect, and much more!
Physics is a system of models of nature according to which all phenomena are explained in terms of matter and force. Sound confusing? It doesn't have to be! Whether you need help with high school physics, need to review for a college physics class, or you're studying for the AP Physics Exam, this physics tutorial will help you understand the basics, such as Newton's Laws, the Law of Universal Gravitation, Kepler's Law and more.
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.
ADHD is one of the most commonly diagnosed-and widely misunderstood-neurological conditions in the world today, affecting nearly 10% of kids and a rising number of adults. But what if having an ADHD brain is actually an asset? A growing number of innovators, entrepreneurs, CEO's, Olympic athletes, and award-winning artists have gone public about their diagnosis, saying that their ADHD, managed effectively, has played a vital role in their success. The Disruptors hears from many of those game-changing people speaking candidly about their ADHD, and intimately takes viewers inside a number of families as they navigate the challenges, and the surprising triumphs, of living with ADHD. The Disruptors takes an immersive look at our approach to ADHD that debunks the most harmful myths, and examines the flip side of this trait that ultimately offers a revelatory understanding of the diagnosis, and real hope for millions of kids, families and adults with ADHD.
