'We know so little about so much': Robert Newman talks skulls, science and psychology

The comedian talks us through why Freud was was wrong, Isaac Newton's brain capacity and why thinking of the brain as a 'wet computer' is an error

I discovered Rob Newman's comedy when I was 16. His shows were relentless: packed full of quotes, arguments, anger, history, philosophy and, above all, bladder-ruining laughs. Oil, urban angst, war, climate change and capitalism - Newman tore into all of these subject and more with verve, wit, and what must have been a well-used library card.

Twenty years on his latest piece, The Brain Show, finds Newman on good form. He's less angry young man, more genial, worried uncle. The laughs are still very much there, perhaps a shade gentler. One thing is still guaranteed: you'll leave with a brain significantly fuller than before and a long reading list.
