Used today in spheres of life as diverse as business strategy, creative writing, medicine, computer science, and theoretical physics, Venn diagrams possess fascinating properties.

The basic Venn diagram is both elegantly simple—three overlapping circles that intersect to create eight distinct areas—and conceptually innovative.

Devised by English logician John Venn — to visually represent complex logical propositions and algebraic statements, the diagrams drew the excited interest of both scholars and the general public. In Cogwheels of the Mindstatistician and geneticist A. og

Cogwheels of the Mind: The Story of Venn Diagrams

Edwards provides an accessible and engaging history of the Venn diagram, its reception and evolution, and its presence in such objects and images as Christian iconography, tennis balls, and flags which provide a rich source of Venn diagrams for Edwards, including those of Switzerland, Poland, and Japan all one-set Venn diagramsGreenland a two-set Venn diagramand Maryland a three-set device.


Edwards begins with a sketch of Venn’s life, his discovery of the three-circle design while developing a series of lectures on symbolic logic at Cambridge University, and the publication of his find in an paper, and, more influentially, his book, Symbolic Logic. Edwards discusses the rival diagrammatic scheme invented by Charles Dodgson, better known as Lewis Carroll, who also developed a board game based on his design.

The author also recreates famous Venn diagrams from history, including Winston Churchill’s of depicting the mutual interests of the British Empire, a united Europe, and the English-speaking world, with the United Kingdom located at the intersection.

Edwards goes on to show how different shapes can be linked together to form artistically beautiful and mathematically important, multi-set Venn diagrams, including the author’s own influential Adelaide variation.

And he delineates the possibilities for expanding the analytic power of these diagrams far beyond those first appreciated by Venn. Edwards even oof readers how to draw complex Venn diagrams on a spherical surface to create “Vennis balls.

A world-class authority, Edwards I found it to be a nice—if light—read, and dkagrams is well worth a look. The overall result should become something of a classic.

He shows how to interlink shapes to form beautiful Venn diagrams. It will also be appreciated by those interested in the process of mathematical discovery.

It should be tbe and enjoyed first-hand.

It is a book in which mathematics and its history are combined in a lovely autobiographical account of a voyage of discovery. The mathematics is interesting, the history is interesting, the personal account is interesting, and the book, with its elegant full-colour pictures and diagrams is beautifully produced.

The author and his publisher are to be warmly thanked and congratulated. Edwards’ penetrating insight into the contentious history of John Venn and his diagram is fascinating. It is a real treat for the logical mind.
