This series on time travel explores humanity's fascination with moving through time, blending science, fiction, and philosophy. It begins by introducing the concept of time travel, drawing from both historical myths and scientific theories like Einstein’s relativity. The journey continues through its portrayal in literature and film, from H.G. Wells to Hollywood blockbusters, before diving into the scientific possibilities of time travel, including wormholes and paradoxes. Ethical and philosophical dilemmas are also examined, alongside the profound cultural impact of time travel on our ...

The story of the men and women who drove the Voyager spacecraft mission, told by a scientist who was there from the beginning. The Voyager spacecraft are our farthest-flung emissaries--11.3 billion miles away from the crew who built and still operate them decades after their launch.

In Calculating the Cosmos, Ian Stewart presents an exhilarating guide to the cosmos, from our solar system to the entire universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why stars implode, how everything began, and how it's all going to end. He considers parallel universes, the fine-tuning of the cosmos for life, what forms extraterrestrial life might take, and the likelihood of life on Earth being snuffed out by an asteroid.

Throughout history, when threatened by wildfires our only defense was to pray for rain and run—until aircraft changed the way we fight fires. Beginning with the Canadian "H-Boats" in 1924, aircraft have become indispensable in detecting and extinguishing wildfires. Fire Eaters tells the incredible stories of the Ontario Provincial Air Service, the first government aerial fire suppression organization in history; one of its pilots, Carl Crossley, who invented the water scoop-up and drop-off system; and the Canadair CL-215, the first purpose-built water bomber.

In his latest work, former senior computer systems designer and bestselling author Gregg Braden merges these ancient and modern world views into a powerful new model of time. Marrying the modern laws of fractal patterns to the ancient concept of cycles, he demonstrates how everything from the war and peace between nations to our most joyous relationships and personal crises are the returning patterns of our past.

Best-selling author and commentator Jay Ingram is back to explain the magic and mysteries of the world around us. Jay takes listeners on a tour of the universe, exploring wonders big and small. From the farthest reaches of space to the most perplexing historical riddles to the marvels of who we are and what we're made of, Jay answers the important questions, such as: What's inside a black hole? Will machines ever learn to feel? And how much pee is in the average pool?

Mars was once similar to Earth, but today there are no rivers, no lakes, no oceans. Coated in red dust, the terrain is bewilderingly empty. And yet multiple spacecraft are circling Mars, on the brink, perhaps, of a staggering find, one that would inspire humankind as much as any discovery in the history of modern science. In this beautifully observed, deeply personal book, Georgetown scientist Sarah Stewart Johnson tells the story of how she and other researchers have scoured Mars for signs of life, transforming the planet from a distant point of light into a world of its own.

Homesteading Space is more than a story of technological and scientific success; it is also an absorbing, sometimes humorous, often inspiring account of the determined, hardworking individuals who shepherded the program through a near-disastrous launch, a heroic rescue, an exhausting study of Comet Kohoutek, and the lab's descent into the Indian Ocean. Featuring the unpublished in-flight diary of astronaut Alan Bean, it is replete with the personal recollections and experiences of the Skylab crew and those who worked with them in training, during the mission, and the return.

Dr. Katie Mack, a theoretical astrophysicist, walks #1 New York Times bestselling author John Green through the history of the entire universe - including the parts that haven’t been written yet.

In the wake of World War II, with America ascendant and the Soviet Union devastated by the conflict, the Space Race should have been over before it started. But the underdog Soviets scored a series of victories—starting with the 1957 launch of Sputnik and continuing in the years following--that seemed to achieve the impossible. It was proof, it seemed, that the USSR had manpower and collective will that went beyond America's material advantages. They had asserted themselves as a world power. But in The Wrong Stuff, John Strausbaugh tells a different story.

Are we on the brink of discovering the first ever evidence that aliens exist? Join astronomer Professor Alan Duffy on his search to answer this question, as he speaks to a new generation of alien hunters embarking on the greatest hunt for extraterrestrials that’s ever been undertaken.

The late great astronomer and astrophysicist describes his personal search to understand the nature of the sacred in the vastness of the cosmos. Exhibiting a breadth of intellect nothing short of astounding, Sagan presents his views on a wide range of topics, including the likelihood of intelligent life on other planets, creationism and so-called intelligent design.

In this intriguing recording, Professor Emeritus Timothy Ferris—one of the world's most respected science writers—explores man's search for life elsewhere in the universe. Ferris combines new discoveries about the origins of life as we know it on Earth with recent revelations about the sun's planets and their moons. Ferris explains why many scientists are convinced that life is abundant throughout the cosmos, and he considers how one day radio telescopes may be used to connect us to an intergalactic Internet and link us to alien civilizations in the far reaches of the universe.

How big is the universe? In the early twentieth century, scientists took sides. One held that the entire universe was contained in the Milky Way galaxy. Their champion was the strong-willed astronomer Harlow Shapley. Another camp believed that the universe was so vast that the Milky Way was just one galaxy among billions—the view that would prevail, proven by the equally headstrong Edwin Hubble.

In 1869, the Atlantic Monthly magazine published a new novella in serial form. This bizarre tale, The Brick Moon, was written by a historian (and Unitarian minister) named Edward Everett Hale, who had already written several well-received novels and articles. However, this was something completely different today, as it was in the genre of what is today considered science fiction. Many people compared the new work to the previous novels of French writer Jules Verne, including From the Earth to the Moon, but Hale’s work was presented as a genuine account of a previous experiment.

Nichol tells the remarkable tale of how the ejection seat was first conceived during the Second World War as countless lives were lost in accidents and in battle. In the wake of the war, that technological race to save aircrew lives using explosive seats continued at an incredible pace. Nichol tells the story of the brave men who risked their lives testing those early devices, and interviewed the first British pilot to eject back in 1949, when ejection, from pulling the handle to being under the parachute, took thirty seconds. Today, that figure is down to around one second.

According to Barker, who first published the book in the 1960s, Rampa's claim that his body had been taken over by a Tibetan Buddhist monk was in no way disproved. In fact, Barker provides a letter from a Tibetan Buddhist scholar stating that Rampa's writings about the inner workings of Tibetan Buddhism were quite accurate and actually revealed closely guarded secrets of the Himalayan monasteries.

In 1965, the great American physicist Richard Feynman famously proclaimed, "I think I can safely say that nobody understands Quantum Mechanics." Is there any wonder why? Particles that pop in and out of existence... Spooky action at a distance that travels faster than light... Infinite universes and branching realities? In this book, we will break through the confusion and reveal to you the most important ideas of Quantum Physics, told through the amazing true story of just 4 bizarre discoveries.

Our understanding of the Universe is about to transform at all levels, from the Planck scale to the vast reaches of space. Recent scientific discoveries show that the information that upholds all of our modern technologies is exactly the same as the universal in-formation that underpins, pervades, and is all we call physical reality. Exploring how information is more fundamental than energy, matter, space, or time, Jude Currivan examines the latest research across many fields of study and many scales of existence to show how our Universe is in-formed and holographically manifested.

For all those who wonder about this bizarre universe and those who want to overthrow the big bang, this handbook gives you "just the facts": the observations that have shaped these ideas and theories. While the big bang holds the attention of scientists, it isn't perfect. The authors pull back the curtains and show how cosmology really works.
