Brian Cox and Robin Ince answer The Infinite Monkey Cage listeners' questions.

Brian Cox and Robin Ince are joined by guests Dara O Briain, Professor Tony Ryan and Dr Gabrielle Walker to discuss the ever-hot topic of climate change. They take a forensic look at the evidence that the climate is indeed changing, how we know that we are responsible, and what can be done to stop it. The scientific willing may be there, but is the political will finally catching up?

Robin Ince and Brian Cox get romantic (although unfortunately not with each other) as they discuss the mathematics of love and the statistics of sex. They are joined on stage by comedian and former maths student Paul Foot, mathematician Hannah Fry and statistician Professor Sir David Speigelhalter, as they discover whether a knowledge of numbers can help you in the affairs of the heart? Can a maths algorithm help you find your perfect mate at a party and what do the statistics tell us about what happens after the party, if you do! They find out whether mathematicians are more successful at dating than comedians, and whether a rational, scientific approach to love and life long happiness is really the answer.

What is Reality?

Brian Cox and Robin Ince are joined by US superstar neuroscientist David Eagleman, Professor Sophie Scott and comedian Bridget Christie to ask what is reality? Is our sense of the world around us a completely personal experience and a construct of our brains? How can we ever know whether what one person perceives is exactly the same as what another person perceives. Is your sense of the world around you an illusion constructed by this extraordinary organ, the brain, that has no direct access to the outside world that it is helping you to understand.

Brian Cox and Robin Ince transport the cage of infinite proportions to the Manchester Museum of Science and Industry. They are joined on stage by impressionist Jon Culshaw and astrophysicists Sarah Bridle and Tim O'Brien as they look up at the sky to discover that everything we see only accounts for 5% of the entire universe. So what is the rest of the universe made of? What are these mysterious elements known as Dark Matter and Dark Energy and would their discovery mean a complete re-writing of the laws of physics as we know them?

Brian Cox and Robin Ince are joined on stage by comedian Shappi Khorsandi, science broadcaster Adam Rutherford and evolutionary geneticist Mark Thomas. They look at the thorny issue of race, and whether there is a scientific definition for the concept of race. Do our genes reveal racial differences, and if so do they tell us anything about our evolutionary history? They also look at the results of their own personal DNA tests...so which panellist is a little bit neanderthal and which one has a genetic history firmly rooted in the North!

Artificial Intelligence

Brian Cox and Robin Ince return for a new series of their award winning science/comedy show. Tonight the infinite monkey's are joined on stage by comedian Jo Brand, neuroscientist Anil Seth, and robotics expert Alan Winfield to discuss Artificial Intelligence. How close are we to creating a truly intelligent machine, how do we define intelligence anyway, and what are the moral and ethical issues that the development of intelligent machines might bring?

The Science of Doctor Who

Brian Cox and Robin Ince explore the legacy of Einstein's great theory, and how a mathematical equation written 100 years ago seems to have predicted so accurately exactly how our universe works. From black holes to the expanding universe, every observation of the universe, so far, has been held up by the maths in Einstein's extraordinary work. So how was he able to predict the events and behaviour of our universe, long before the technology existed to prove he was right, and will there ever be another theory that will supersede it? Brian and Robin head up the iconic Lovell telescope at Jodrell Bank to explore Einstein's theory in action, and talk to scientists who are still probing the mysteries hidden within General Relativity.

It's 100 years since the publication of Einstein's great theory, and arguably one of the greatest scientific theories of all time. To mark the occasion, Brian Cox takes Robin Ince on a guided tour of General Relativity. With the help of some of the world's leading cosmologists, and a comedian or two, they explore the notions of space time, falling elevators, trampolines and bowling balls, and what was wrong with Newton's apple. It's a whistle stop tour of all you'll ever need to know about gravity and how a mathematical equation written 100 years ago predicted everything from black holes to the Big Bang, to our expanding universe, long before there was any proof that these extraordinary phenomena existed.
