â€œCombin[es] matters of biography, science, engineering, technology, art, history, economics and politics seemingly effortlessly and definitely seamlessly. An excellent book and a joy to read.â€â€”Henry Petroski, Wall Street Journal
Augustin Fresnel (1788â€“1827) shocked the scientific elite with his unique understanding of the physics of light. The lens he invented was a brilliant feat of engineering that made lighthouses blaze many times brighter, farther, and more efficiently. Battling the establishment, his own poor health, and the limited technology of the time, Fresnel was able to achieve his goal of illuminating the entire French coast. At first, the British sought to outdo the new Fresnel-equipped lighthouses as a matter of national pride. Americans, too, resisted abandoning their primitive lamps, but the superiority of the Fresnel lens could not be denied for long. Soon, from Dunkirk to Saigon, shores were brightened with it. The Fresnel legacy played an important role in geopolitical events, including the American Civil War. No sooner were Fresnel lenses finally installed along U.S. shores than they were drafted: the Union blockaded the Confederate coast; the Confederacy set about thwarting it by dismantling and hiding or destroying the powerful new lights.
Levittâ€™s scientific and historical account, rich in anecdote and personality, brings to life the fascinating untold story of Augustin Fresnel and his powerful invention.

The Old Man In Apartment 620
"Freedom is never more than one generation away from extinction. We didn't pass it to our children in the bloodstream. It must be fought for, protected, and handed on for them to do the same, or one day we will spend our sunset years telling our children and our children's children what it was once like in the United States where men were free."
This is a story of how such a conversation might sound.
