A Dance to the Music of Time 12 - Hearing Secret Harmonies

Hearing Secret Harmonies is the final novel in Anthony Powell's twelve-volume masterpiece, A Dance to the Music of Time. It was published in 1975 twenty-four years since the first book, A Question of Upbringing appeared in 1951.
Completing his meditation upon the themes of time and will, the author recounts the narrative in the voice of a convincingly middle-aged Jenkins. (In the television adaptation of the novels an older actor was chosen to play Nick in the final part.)

Hidden Harmonies: The Lives and Times of the Pythagorean Theorem

A squared plus b squared equals c squared. It sounds simple, doesn't it? Yet this familiar expression is a gateway into the riotous garden of mathematics, and sends us on a journey of exploration in the company of two inspired guides, acclaimed authors Robert and Ellen Kaplan. With wit, verve, and clarity, they trace the life of the Pythagorean theorem, from ancient Babylon to the present, visiting along the way Leonardo da Vinci, Albert Einstein, President James Garfield, and the Freemasons-not to mention the elusive Pythagoras himself, who almost certainly did not make the statement that bears his name.
