The New Polymath, by Vinnie Mirchandani, is an ambitious, wide-ranging and celebratory exploration of technology innovation in the 21st century. The book epitomizes the title (a polymath is someone who excels in many disciplines) in taking on the distinct, though certainly overlapping, disciplines of infotech, cleantech and healthtech – and all the various technologies and practices that support them. It evokes the spirit of polymaths throughout history (Sir Isaac Newton, Benjamin Franklin, Hypatia of Alexandria, and the ultimate polymath, Leonardo da Vinci) and seeks their equivalents in our own times in both individuals (Bill Joy, Nathan Myhrvold) and organizations. Most provocative, it sets up a parallel between our age and the 14th century, when the Late Middle Ages, or Dark Ages, gave way to the Renaissance, or rebirth. Mirchandani is hopeful that we are entering another Renaissance.
