Showing results for "Science" in Astronomy

Consider these commonly held scientific beliefs: Planetary orbits are fixed ellipses; we only use 10 percent of our brains; nothing travels faster than light; a thrown object’s trajectory is a parabola. They seem correct, but they’re all misconceptions that aren’t entirely accurate. There’s much more to the story than you think. These magnificent 24 lectures are devoted to busting myths, clearing up confusion, and giving you scientific epiphanies that could change how you think about your everyday world.

Science fiction allows us to go places we can only dream of seeing - other worlds, distant stars, entirely different galaxies. While not every story is concerned with the hard science behind space travel and other futuristic ventures, fiction can give us amazing insight into what we could be capable of and what we dream of doing. In these 10 lectures, Professor Erin Macdonald interweaves real science and the achievements of the imagination to reveal the truth that underlies our favorite stories and sheds light on what the future may hold.

How can we make intelligent decisions about our increasingly technology-driven lives if we don’t understand the difference between the myths of pseudoscience and the testable hypotheses of science? Pulitzer Prize-winning author and distinguished astronomer Carl Sagan argues that scientific thinking is critical not only to the pursuit of truth but to the very well-being of our democratic institutions.

The Sun, Moon, and stars are crucial to your daily existence. The perfect regularity of the heavens is the only guaranteed part of life and inspires deep religious and philosophical ideas, while unexpected events such as eclipses and comets incite fear. Experience this ancient outlook with noted astrophysicist and historian of astronomy Professor Bradley Schaefer of Louisiana State University. An award-winning teacher, Dr. Schaefer takes you around the world, exploring the close relationship that people thousands of years ago had with the sky.

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

Author of the New York Times best seller The Beginning of Infinity, David Deutsch, explores the four most fundamental strands of human knowledge: quantum physics, and the theories of knowledge, computation, and evolution - and their unexpected connections. Taken together, these four strands reveal a deeply integrated, rational, and optimistic worldview. It describes a unified fabric of reality that is objective and comprehensible, in which human action and thought are central.

This course chronicles the history of Earth and life on Earth from the point of view of the minerals that made it all happen. A major theme is how minerals and life coevolved, leading to the unprecedented mineral diversity on our world compared to the other planets in the solar system. Professor Hazen tells this epic story in 48 action-packed lectures that take you from the big bang to the formation of the solar system to the major milestones that marked the evolution of Earth and life.

Over two millennia ago, a Greek philosopher had a number of wondrous insights that paved the way to cosmology, physics, geography, meteorology, and biology, setting in motion a new way of seeing the world. In this elegant work, acclaimed physicist Carlo Rovelli brings to light the importance of Anaximander's overlooked legacy to modern science. He examines Anaximander as a scientist interested in shedding light on the deep nature of scientific thinking, which Rovelli locates in his rebellious ability to reimagine the world again and again.

For half a century, Vega was the most trusted star in astronomy—the zero point of the brightness scale, the calibration standard for every major telescope, the benchmark of stellar normalcy. Then, in 2006, two independent teams of astronomers discovered that everything we believed about it was wrong. Vega is not a calm, slowly spinning star.

As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects and plans for high-tech hardware that could deflect an incoming object from a collision course - a procedure depicted in several Hollywood movies.

Mars is back. Suddenly everyone - from Elon Musk to Ridley Scott to Donald Trump - is talking about going to the Red Planet. When the Apollo astronauts walked on the Moon in 1969, many people imagined Mars would be next. However NASA’s Viking 1, which landed in 1976, was just a robot. The much-anticipated crewed mission failed to materialise, defeated by a combination of technological and political challenges.

Michael Schneider leads us on a spectacular journey along the numbers one through 10 to explore the mathematical principles made visible in flowers, shells, crystals, plants, and the human body, expressed in the symbolic language of folk sayings and fairy tales, myth and religion, art and architecture. This is a new view of mathematics, not the one we learned at school but a comprehensive guide to the patterns that recur through the universe and underlie human affairs. 

At the two four-kilometre long LIGO observatories in the US, scientists developed incredibly sensitive detectors, capable of spotting a movement 100 times smaller than the nucleus of an atom. In 2015, they spotted the ripples produced by two black holes spiralling into each other, setting spacetime quivering. This was the first time black holes had ever been directly detected, and it promises far more for the future of astronomy. Brian Clegg presents a compelling story of human technical endeavour and a powerful new path to understand the workings of the universe.

The iron in your blood was forged in the nuclear furnace of a dying star. The gold in your jewelry was born in the collision of neutron stars so violent it sent ripples through spacetime itself. The carbon in your DNA survived a stellar explosion and a billion-year journey through space before becoming part of you. Born from Catastrophe reveals the extraordinary truth behind these statements: we are not just made of stardust, but of stardust created through the most violent events in the universe.

Ka-boom! probes extremes of size and speed, depth and density, and reveals the stickiest, sweetest, smelliest and nastiest substances known to science. In an unabashed celebration of the exceptional, David Darling takes an enlightening journey through the universe's weirdest and most wonderful extremes.
