All About Light From Lenses to Lazers: covers inventions for communicating, viewing and imaging from ancient lighthouses lit by flames; through the first lenses for spectacles, microscopes and telescopes, and the development of the camera and movie projector; to X-rays, scanners and ultrasound, and sonar, radar and lasers. All these triggered discoveries and practical uses. So, Galileo was the first to see the four big moons of Venus, through his telescope; Marie Curie ordered mobile X-ray units for the World War I battlefield: and Explorer 6 was the first satellite to take pictures of Earth in 1959. Incredible Inventions takes a lively, sweeping look at some of the most important light-bulb moments in history. You ll see how one idea often led to another, and revealed something new and exciting about our world. The four books provide a road map of inventions, divided along the lines of optics; movement; communications; and agriculture/industry. Dotted throughout are inventors hilarious flops and oddities, too. Feeling brave? How about a ride in an aerial steam carriage!
