  • WWII Atomic Bomb Project Had More Than 1,500 “Leaks”

    The #Manhattan_Project to develop the first atomic bomb during World War II was among the most highly classified and tightly secured programs ever undertaken by the U.S. government. Nevertheless, it generated more than 1,500 #leak investigations involving unauthorized disclosures of classified Project information.

    That remarkable fact is noted in the latest declassified volume of the official Manhattan District History (Volume 14, Intelligence & Security) that was approved for release and posted online by the Department of Energy last month.

    • Norbert Wiener, Cybernétique et société, 1950, trad. P.-Y. Mistoulon, Seuil, 2014, p. 152 :

      Dans le problème du déchiffrement, l’information la plus importante dont nous puissions disposer est celle de savoir que le message lu n’est pas du charabia. Une méthode courante pour déconcerter les décodeurs consiste à mêler au message normal un message #indéchiffrable, simple assemblage de caractères dénués de sens. De même, si l’on considère des problèmes naturels tels que ceux des réactions et explosifs atomiques, l’élément isolé d’information le plus considérable que nous puissions divulguer est leur existence. Dès que le savant étudie une question qu’il sait soluble, toute son attitude est modifiée. Il a déjà franchi la moitié du chemin qui le sépare de cette solution.

      Aussi est-il parfaitement exact d’affirmer que l’unique #secret relatif à la bombe atomique et qui, au lieu d’être livré au public et à tous les ennemis éventuels sans restriction, aurait pu être gardé, était la possibilité de la construire.

  • nuclear testing

    Japanese artist Isao Hashimoto has created a beautiful, undeniably scary time-lapse map of the 2053 nuclear explosions which have taken place between 1945 and 1998, beginning with the Manhattan Project’s “Trinity” test near Los Alamos and concluding with Pakistan’s nuclear tests in May of 1998. This leaves out North Korea’s two alleged nuclear tests in this past decade (the legitimacy of both of which is not 100% clear).

    Each nation gets a blip and a flashing dot on the map whenever they detonate a nuclear weapon, with a running tally kept on the top and bottom bars of the screen. Hashimoto, who began the project in 2003, says that he created it with the goal of showing"the fear and folly of nuclear weapons." It starts really slow — if you want to see real action, skip ahead to 1962 or so — but the buildup becomes overwhelming.

    The Smurfs and the Death-Ray Apocalypse

    Animators who worked on The Smurfs told us it took 5,000 eight-core Intel processors to render the film and that, on average, it took one animator a week to render three to four seconds of footage.

    Considering that the Manhattan Project rode on the computing power of six dudes with slide rules and blunt pencils, we figure these machines can either animate a bunch of small blue people that live in mushrooms, or they can plot the destruction of humankind.

    Anybody else in the world would be using these computers to design nuclear weapons, stealth fighters, UAVs or Lara Croft-crocodile hybrids, but not us. America uses its supercomputers to render monomaniacal blue Belgian gnomes.
