Carl Sagan teaches students in a classroom in his childhood home in Brooklyn, New York, which leads into a history of the different mythologies about stars and the gradual revelation of their true nature. In ancient Greece, some philosophers (Aristarchus of Samos, Thales of Miletus, Anaximander, Theodorus of Samos, Empedocles, Democritus) freely pursue scientific knowledge, while others (Plato, Aristotle, and the Pythagoreans) advocate slavery and epistemic secrecy.
The Sky at Night looks back at the last ten years of astronomy and ponders the most significant milestones and revelations. With the help of six distinguished astronomers, Chris and Maggie consider the state of astronomy in 2020 and wonder what new, exciting discoveries await us across the rest of the decade, as a host of new ground and space telescopes come online. Astronomer Royal Lord Martin Rees is among the guests to walk along the Astronomical Wall of Discovery in this one-hour special.
We think of comets as beautiful glowing balls of light streaking across our skies with their long sweeping tails, yet comets are so much more than just a cosmic firework display. Comets have a uniquely important place in modern science. As time machines from the early universe, they could hold the key to unlock the secrets of the cosmos. Comets could even be the origin of life itself. We follow the incredible odyssey of a comet as it sails through the solar system, watching it's every move as it evolves from a dormant chunk of ice and rock into a tumbling, violently active nucleus engulfed in a gaseous haze. What we learn is a revelation; comets are even more mysterious and fascinating than we had ever imagined.
In this captivating film hosted by Anderson Cooper, viewers are presented with an insightful exploration of artificial intelligence (AI), its profound implications, and the ethical dilemmas it poses. The documentary begins with a startling revelation: what appeared to be Anderson Cooper was actually an AI-generated version, raising questions about the authenticity of what we see and hear. The narrative then shifts to broader concerns about AI replacing human roles across industries and its capability to outperform humans in tasks ranging from driving to creating art. Viewers are taken on a journey through various facets of AI, from the streets of San Francisco, where robot taxis hint at a future dominated by AI, to the insights of Yoshua Bengio, a pioneer in deep learning. The film also addresses the darker side of AI, including the potential for misuse and the challenges in distinguishing between reality and AI-generated content. The climax of the documentary presents a critical question: Can AI save humanity, or does it pose a threat to our existence? This thought-provoking exploration of AI's impact on our world is a must-watch for anyone curious about technology and its intersection with human life.
Electricity is not just something that creates heat and light, it connects the world through networks and broadcasting. After centuries of man's experiments with electricity, the final episode tells the story of how a new age of real understanding dawned - how we discovered electric fields and electromagnetic waves. Today we can hardly imagine life without electricity - it defines our era. As our understanding of it has increased so has our reliance upon it, and today we are on the brink of a new breakthrough, because if we can understand the secret of electrical superconductivity, we could once again transform the world.
With every bite, we make choices about our health. But what if those choices, even the most well-intentioned ones, are not as safe as we believe? Poisoned: The Dirty Truth About Your Food challenges our perceptions and urges viewers to question: In the modern food landscape, is anything truly safe? The film is a truly call to action for the officials who have the power to mitigate the danger caused by foodborne pathogens that kill thousands of people every year.
