In spring 1943, Nobel Prize winning physicist Erwin Schrödinger gave a series of lectures at Trinity College, Dublin. These lectures were subsequently published as the non-fiction science book 'What is life?'.
Schrödinger took a physicist's approach to the question, asking whether living organisms could be understood in terms of fundamental matter. Francis Crick, co-discoverer of the structure of the DNA molecule, has credited the book as being the inspiration for his initial research.
In this lecture, Nobel Prize winner and President of the Royal Society, Sir Paul Nurse, also takes inspiration from the book to ask what can we now say about the nature of life?
