The Blurb On The Back:
This book tells the human story of one of man’s greatest intellectual adventures - how it came to be understood that light travels at a finite speed, so that when we look up at the stars, we are looking back in time. And how the search for an absolute frame of reference in the universe led so improbably to Einstein’s famous equation E = mc2,, which represents the energy that powers the stars and unclear weapons. From the ancient Greeks measuring the distance to the Sun, to today’s satellite navigation, the book takes the reader on a gripping historical journey. We see how Galileo with his new telescope discovered the moons of Jupiter and used their eclipses as a global clock, allowing travellers to find their Longitude. And how Ole Roemer, noticing that the eclipses were a little late, used this to obtain the first measurement of the speed of light, which takes eight minutes to get to us from the Sun. We then move from the remarkable international collaborations to observe the Transits of Venus, including Cook’s voyage to Australia, to the extraordinary achievements of Young and Fresnel, whose discoveries eventually taught us that light travels as a wave but arrives as a particle, and all the quantum weirdness which follows. In the nineteenth century, we find Faraday and Maxwell, struggling to understand how light can propagate through the vacuum of space unless space is filled with a ghostly vortex Aether foam. We follow the brilliantly gifted experimentalists Hertz, discoverer of radio, Michelson with his search for the Aether wind, and Foucault and Fizeau with their spinning mirrors and light beams across the rooftops of Paris. Messaging faster than light, Einstein’s theory, quantum entanglement, and the reality of the quantum world, conclude this saga.
( The Review (Cut For Spoilers): )
The Verdict:
John C H. Spence teaches physics at Arizona State University and is Snell Professor and Director of Science for the National Science Foundation’s BioXFEL Consortium. This is an absorbing historical account of how scientists learned to measure the speed of light but although I enjoyed the personal details Spence gives on the scientists and he does try to simplify the complicated mathematical formulae, some of the book was above my skill level.
