||1909: Panama Canal: Workers pour the first concrete for the Panama Canal at a lock site at Gatun. Finishing all the locks there took nearly four years. A dam holds back the artificial Gatun Lake to supply water for the locks. The Gatun gate was closed on 27 Jun 1913, allowing Gatun Lake to fill to its planned depth. A few months later, on 26 Sep 1913, the tugboat Gatunmade a trial run through the Gatun Locks. The control panel was not ready for the event, so the locks were operated manually. Everything worked perfectly. The Panama Canal crosses the Isthmus of Panama, joining the Atlantic and Pacific Oceans. Built 1904-14, it is only half the length of the Suez Canal. Unlike the Suez, the Panama Canal uses locks to raise and lower ships.


||1917: Ralph Eugene Lapp born ... nuclear physicist and author who began his career in high-energy physics research with Arthur H. Compton. Lapp then worked at Chicago on the Manhattan Project. With 69 others, he signed Leo Szilard’s 17 Jul 1945 petition to President Truman, the month before the attack on Hiroshima. They urged that Japan should have an opportunity to surrender before use of the atom bomb. (Nevertheless, the actual attack was by surprise.) After the war, he researched the results in Japan. Lapp lectured across the U.S. He wrote 22 books on nuclear safety, including the dangers of nuclear fallout in The Voyage of the Lucky Dragon (1958). A Post book reviewer in 1956 called him “a one-man atomic truth squad and nuclear lie detector.” Pic: https://www.todayinsci.com/8/8_24.htm
