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.Levitt’s scientific and historical account, rich in anecdote and personality, brings to life the fascinating untold story of Augustin Fresnel and his powerful invention.

    Elite members of the climbing community have likened him to the Michael Jordan, Cal Ripkin, or Michael Phelps of the climbing world. The 2015 expedition he would lead came just one short year after the notorious Khumbu Icefall avalanche claimed the lives of sixteen Sherpas. Dave and his team--Sherpa sirdar Chhering Dorjee, assistant guide JJ Justman, base-camp manager Mark Tucker, and the eight clients who had trained for the privilege to attempt to summit with Dave Hahn--spent weeks honing the techniques that would help keep them alive through the Icefall and the Death Zone. None of this could have prepared them for the earthquake that shook Everest and all of their lives on the morning of April 25, 2015. Shook tells their story of resilience, nerve, and survival on the deadliest day on Everest.
