By our third year, most of us will have learned to count. Once we know how, it seems as if there would be nothing to stop us counting forever. But, while infinity might seem like a perfectly innocent idea, keep counting and you enter a paradoxical world where nothing is as it seems.

Mathematicians have discovered there are infinitely many infinities, each one infinitely bigger than the last. And if the universe goes on forever, the consequences are even more bizarre. In an infinite universe, there are infinitely many copies of the Earth and infinitely many copies of you. Older than time, bigger than the universe and stranger than fiction. This is the story of infinity.

Neuroscience has learned much about the brain’s activity and its link to certain thoughts. As Lesley Stahl reports, it may now be possible, on a basic level, to read a person’s mind.

Richard Feynman on the rational scientific method; increments and revolutions and castling.

Leading theoretical physicist and futurist Dr. Michio Kaku explores the cutting edge science of today, tomorrow, and beyond. He argues that humankind is at a turning point in history. In this century, we are going to make the historic transition from the ‘Age of Discovery’ to the ‘Age of Mastery’, a period in which we will move from being passive observers of nature to its active choreographers. This will give us not only unparalleled possibilities but also great responsibilities.

In the opening instalment, Kaku explains how artificial intelligence will revolutionise homes, workplaces and lifestyles, and how virtual worlds will become so realistic that they will rival the physical world. Robots with human-level intelligence may finally become a reality, and in the ultimate stage of mastery, we’ll even be able to merge our minds with machine intelligence.

Controversially, Kaku documents the work of scientists using a combination of artificial intelligence and neuroscience technology transform a person suffering from major depressive disorder into one who is happy and content by the push of a button.

In an all new program, science comedian Brian Malow spins hilarious and thought-provoking routines on evolution, our brains, relativity, Roomba, extraterrestrial life, and more. What do the frontiers of science hold? Journey from space travel to time travel, from extremophiles in the ocean depths to black holes in the far reaches of space. This program is for all audiences! Music is not just for musicians. Art is not just for artists. And science is not just for scientists.
