A historical account from 1985 of the long standing debate between Niels Bohr and Albert Einstein regarding the validity of the quantum mechanical description of atomic phenomena and observation of quantum states with respect to the uncertainty principle and quantum entanglement. Starring some famous physicists, John Archibald Wheeler, John Stewart Bell, Alain Aspect, David Bohm and others. Interesting material about the famous concept of "Spooky action at a distance" as quoted by Albert Einstein, an example of his displeasure at the nature of non-locality as a consequence of quantum entanglement which is nevertheless how particles in the universe work.
It's called the speed limit of the universe. Einstein blew all of our minds when he worked out the Theory of Relativity, and showed that space and time were malleable substances. He also theorized that we as humans can never travel faster than the speed of light, which leaves the stars and other galaxies almost impossibly out of our reach. But the dreams of Star Wars and Star Trek are not dead. In fact, there could be ways to travel faster than the speed of light - and some of them are already being tested in labs around the world.

Nuclear Energy is a controversial subject. The pro- and anti-nuclear lobbies fight furiously, and it's difficult to decide who is right. So we're trying to clear up the issue - in this video we discuss how we got to where we are today, as the basis for discussion.

Particle physicist Dr Brian Cox wants to know why the Universe is built the way it is. He believes the answers lie in the force of gravity. But Newton thought gravity was powered by God, and even Einstein failed to completely solve it. Heading out with his film crew on a road trip across the USA, Brian fires lasers at the moon in Texas, goes mad in the desert in Arizona, encounters the bending of space and time at a maximum security military base, tries to detect ripples in our reality in the swamps of Louisiana and searches for hidden dimensions just outside Chicago.
A cloak of invisibility isn't just some Harry Potter fantasy- Dr. Michio Kaku draws up the blueprints for a real invisibility cloak and reveals that vanishing into thin air could be much closer than we think.
