So much of our universe is unknown … 96% in fact. Scientists don’t really know how gravity works – or why and how so many other things in our world actually occur.

Best known for his work on comedy television programmes Not the Nine O’Clock News, Spitting Image, The Hitchhiker’s Guide to the Galaxy, Blackadder and QI, British comic genius, producer and writer, John Lloyd, turns his curiosity to knowledge itself:

People who ask new questions are the geniuses. Ignorance is at the heart of any kind of discovery.”

After 40 years of working in comedy, John Lloyd still has no idea what actually makes something funny, but he does know that wisdom is a question of working out what the most important things in life are.
