## Berlinski's Euclid Is Out Now: A Wonderful Review

Congratulations to our colleague and contributor David Berlinski whose new book is out! *The King of Infinite Space: Euclid and His Elements* gets a wonderful review in the *New York Journal of Books* by Robert Schaefer, a Research Engineer at MIT Haystack Observatory. Schaefer concludes: "*The King of Infinite Space* is for anyone who cares about Euclid, geometry, the philosophy of mathematics and, most especially, for those who appreciate fine writing."

Yes indeed. More:

Elements,The King of Infinite Spaceis surprisingly compelling. Dr. Berlinski goes about his business in an artful manner, at times serious and straightforward, at times stream-of-consciousness or poetic. The spirit of this book is something this reviewer can only hope to capture.Euclid was born in the fourth century BCE and died sometime in the third. Much of Euclid's life we only know only indirectly through the writings of others--through copies of copies. His

Elementscomprises 13 books, the first four (of which have been the longest lived) concern geometry, the study of shapes in space--points, straight lines, circles, squares, right angles, triangles, rectangles, magnitudes, proportions, and solids. Modern versions of theElementsare based on a 10th century Greek text; even so, theElementshave been the most successful of all mathematical textbooks and the oldest complete text in the Western mathematical tradition.Dr. Berlinksi claims that the

Elementsdraws a historical line in the sand that separates the unorganized before from the organized after, and that Euclid also provides a double insight, the first that geometry could be organized into a whole, and second that geometric propositions could be, must be logical.
