A short look at different adventures in thought, economics and religion. Can a cat be both alive and dead? Can a computer think? How does a tortoise beat Achilles in a race? Voiced by comedian David Mitchell, these fast-paced animations explain six famous thought experiments, from the ancient Greeks to Albert Einstein, that have changed the way we see the world.

Subjects as vast as time travel, infinity, quantum mechanics and artificial intelligence, are squeezed into 60-second clips that will tickle your funny bone and blow your mind.

Ever shaken an invisible hand? Been flattened by a falling market? Or wondered what took the bend out of Phillips’ curve? David Mitchell helps reveal some of the great dilemmas faced by governments trying to run an economy – whether to save or spend, control inflation, regulate trade, fix exchange rates, or just leave everyone to get on with it and not intervene.

You’ll learn why Adam Smith put such a high price on free markets, how Keynes found a bold new way to reduce unemployment, and what economists went on to discover about the impact of policy on people’s and businesses’ behaviour – which may not always be entirely rational.

Ever wondered why Karl Marx thought religion was like opium – or whether religion is possible without a god? This series examines different ways that religion has been viewed by non-religious thinkers. As well as Marx and Dawkins, religion is put under the microscope by thinkers Auguste Comte and JJ Bachoffen.
