In Measure for Measure, Thomas Levenson offers a compelling account of how scientific thinking developed from the day 2,500 years ago when Pythagoras discovered the musical scale to the present day. The story unfolds through the tales of instruments scientific and musical: the organ, the microscope, the still, the scales, Stradivari's miraculous violins and cellos, computers, and synthesizers. What emerges is a unique portrait of science itself as an instrument, our single most powerful way of understanding the world. Yet perhaps the most important invention of modern science has been the power to countenance its own limitations, to find the point beyond which science can explain no more, to rediscover that science, like music, is an art.
