Doubt and Certainty in Science: A Biologist’s Reflections on the Brain

The book DOUBT AND CERTAINTY IN SCIENCE: A BIOLOGIST'S REFLECTIONS ON THE BRAIN by J. Z. Young is based his lectures of the same name delivered in the Reith Lectures on the BBC in 1950.

J. Z. Young’s work in the 1930s on signal transmission in, and the fibre structure of, nerves inspired the work of Sir Andrew Huxley and Sir Alan Hodgkin for which they received a Nobel prize. And many people believe that he should have had a Nobel prize for his work on the giant fibres of squids, a 1930 discovery that formed the basis for our present understanding of how nerves work.
