Hannah Fry shows that when it comes to the universe, size really does matter. Hannah takes the audience into a thought experiment where the size of everything can be changed to reveal why things are the size they are.

Planet Earth has been home to humankind for over 200,000 years, but with a population of 7.3 billion and counting and limited resources, this planet might not support us forever. Professor Stephen Hawking thinks the human species will have to populate a new planet within 100 years if it is to survive. With climate change, pollution, deforestation, pandemics and population growth, our own planet is becoming increasingly precarious.

Kevin Delaney leaves his lab behind to hit the streets for experiments that will blow your mind in Street Science.
Combining scientific method with curiosity and ingenuity, these larger than life demos produce fire, explosions and colorful reactions as Kevin's side kick Darren Dyk catches it all with amazing slow motion footage that provides insight of what the eye can't normally see.

Watching us from space, satellites orbit the Earth at 17,000 miles an hour, capturing images of our world that are breathtaking, and sometimes bizarre. This unique perspective reveals objects and phenomena that defy explanation - massive tsunamis that disappear without trace, a sinister blood-red lake in war-torn Baghdad and a whirlpool in the ocean the size of Connecticut.

Charles drifts through politics, religion and psychoanalysis, rejecting them all. Once he realises the depth of his disgust with the moral and physical decline of the society he lives in, he decides that suicide is the only option…

In a month when the tally of confirmed exoplanets passed 5,000, it's astonishing to remember that just 30 years ago, the notion of planets outside our own solar system was, well – just a notion. Since the first extrasolar planet was discovered in 1992, a staggering array of other worlds have been identified, including many in solar systems quite unlike our own.

Explore the world of the seemingly impossible with the all-new series SCI FI SCIENCE. Hosted by internationally-renowned physicist and co-founder of string field theory, Dr. Michio Kaku, this series poses the idea that science fiction may not be so far from science fact. Examine topics that currently seem so far outďż˝ of the realm of possibility, such as invisibility cloaks, teleportation, time travel and more. Kaku uses discussion of speculative technologies to introduce topics of fundamental physics to the reader.

Albert Einstein: Physicist, Philosopher, Humanitarian examines Einstein's revolutionary innovations in physics, his philosophical reflections on the methods and foundations of science, and his public efforts championing a variety of social causes. By the end of these 24 lectures, you'll have become better acquainted with the whole Einstein—his scientific ideas, his personal philosophies, his thought processes, and his impact on both his time and ours.

Everything we can see with our eyes and with powerful instruments—everything we think of as atom-based matter—is only 5 percent of what we know exists. The rest of the contents of the cosmos is invisible to our current methods of detection—but something out there is holding galaxies and galaxy clusters together, and something else is causing space itself to fly apart. These invisible components are dark matter and dark energy, the most eagerly studied subjects in astronomy and particle physics today.

With scientists perhaps on the verge of unlocking the deepest secrets of the universe and with breaking news of discovery after discovery at the frontiers of research, understanding physics has never been so important. This course puts the awe-inspiring—and at times mind-bending—concepts behind relativity and quantum mechanics within reach of anyone who wants to understand them.Ph.D., Dartmouth College
