Ron Aharoni's little daughter returned one day from a visit to the dentist, and asked him, "Do you know how to make the anesthetic shot painless? You['ve] give[n] an anesthetic shot before". Of course, to make the anesthetic shot painless, another shot is needed.
Amusing? Indeed. But strangely, this mode of thought also has a serious side called 'circularity', or 'self-reference', and it is the protagonist of our story.
'Circularity' is the story of a Janus-faced conceptual structure that, on the one hand led to deep scientific discoveries, and on the other hand is used to trick the mind into believing the impossible. Alongside mathematical revolutions that eventually led to the invention of the computer, the book describes ancient paradoxes that arise from circular thinking.
What is the affinity between jokes and the celebrated theorem of Gödel, stating that not everything true about numbers can be proved from a simple set of axioms? And how do these two connect to the problem of moral responsibility--how can a person be held responsible for his or her actions if his or her choice is governed by physical rules? And what is the connection of all these to the invention of the computer?
Aharoni's fascinating book, Circularity: A Common Secret to Paradoxes, Scientific Revolutions and Humor, discusses all these and binds together mathematics, philosophy and the secrets of humor.
This book retails at US$28 / £18 (paperback) and US$58 / £38 (hardback) at major bookstores. More information on Circularity can be found at http://www.
