Michael Salla: Reagan Records and Space Command Anti-Gravity Fleet Reagan Records and Space Command Anti-Gravity Fleet Michael Salla Honolulu Expolotics Examiner April 15, 2009 On April 13, the National Archive Records Administration made available almost 250,000 pages of documents from President Reagan’s administration. Lunch with 5 top space scientist. This is curious since the Space Shuttle holds a maximum of eight people and only five were built for space flight. The United States has organized its military forces into ten unified combatant commands respectively led by a single four star General or Admiral who reports directly to the Secretary of Defense. From 1985 to 2002 Space Command was responsible for outer space operations by the U.S. military. Rumors that the U.S. has a highly classified fleet of antigravity vehicles have circulated for years. Corporate and military whistleblowers have come forward to claim first hand knowledge of classified space vehicles using antigravity technology such as the Aurora and TR-3B.
We come from the future. untitled Perpetual Futility A short history of the search for perpetual motion. by Donald E. Simanek Popular histories too often present perpetual motion machines as "freaks and curiosities" of engineering without telling us just how they were understood at the time. They also fail to inform us that even in the earliest history of science and engineering, many persons were able to see the futility and folly of attempts to achieve perpetual motion. Sometimes a particular device comes to us with a label, such as "Bishop Wilkins' magnetic perpetual motion machine." Popular articles leave the impression that the inventor believed it was a perpetual motion machine. Bhaskara's Wheels. Villard de Honnecourt was born in the late 12th century and probably lived and worked in the north of France from 1225 to 1250. The most celebrated of his machine designs was for a perpetual motion wheel. Villard's diagram shows seven hammers, and he insisted on an odd (uneven) number of hammers, explaining 56. That's it.
Des couches absorbantes aux étoiles filantes, l'histoire étonnante du caca dans l'espace Cela peut paraître trivial, mais c'est l'un des défis de l'exploration spatiale : résoudre le grand casse-tête du caca dans l'espace (le pipi pose moins de problèmes). Depuis que les missions habitées durent plusieurs jours, voire des mois, les agences spatiales doivent assurer l'hygiène et la santé de leurs astronautes, avec les contraintes qu'impose la vie dans l'espace. Juste après son arrivée à bord de l'ISS, le spationaute Thomas Pesquet a d'ailleurs dû réparer des toilettes en panne. C'est l'occasion pour franceinfo de vous raconter l'histoire du caca spatial, ponctuée de petits incidents et de grandes avancées technologiques. Le premier homme envoyé dans l'espace, le 12 avril 1961, n'a pas eu à se poser de questions. Un mois plus tard, Alan Shepard, premier Américain dans l'espace, n'a pas cette chance. Les astronautes des missions américaines Mercury, Gemini, et Apollo essuient donc les plâtres. Revenons dans les années 1970.
How Things Work - How Things Work Home Page Personal and Historical Perspectives of Hans Bethe Imprimer un satellite en 3D ? Avec la NASA, c'est possible ! Si vous avez toujours rêvé d’avoir un satellite bien à vous et à moindres frais, vous vous dites que, peut-être, l’impression 3D est la solution. Et vous avez bien raison. Enfin, dans un certain sens. Car non, malheureusement, vous ne pouvez pas (encore) imprimer un véritable satellite à mettre en orbite autour de la Terre ou d’un quelconque autre caillou. C’est la NASA qui a mis en ligne pas moins de 21 fichiers qui ne sont autres que des modèles pour imprimer en 3D une version miniature de quelques-uns de ses satellites et autres sondes. La liste des modèles disponibles est assez diversifiée. Mais on trouve aussi des objets un peu particuliers, comme des astéroïdes avec notamment Eros dans le lot. Grâce à la NASA, vous pouvez donc imprimer en 3D vos objets spatiaux favoris, mais pas seulement, puisque l’agence nous fournit également les fichiers sources Blender de ces mêmes objets : vous pourrez donc créer des scènes 3D en les intégrant.

Ask a Mathematician / Ask a Physicist | Your Math and Physics Questions Answered An Essay by Einstein -- The World As I See It "How strange is the lot of us mortals! Each of us is here for a brief sojourn; for what purpose he knows not, though he sometimes thinks he senses it. But without deeper reflection one knows from daily life that one exists for other people -- first of all for those upon whose smiles and well-being our own happiness is wholly dependent, and then for the many, unknown to us, to whose destinies we are bound by the ties of sympathy. "I have never looked upon ease and happiness as ends in themselves -- this critical basis I call the ideal of a pigsty. "My passionate sense of social justice and social responsibility has always contrasted oddly with my pronounced lack of need for direct contact with other human beings and human communities. "My political ideal is democracy. "This topic brings me to that worst outcrop of herd life, the military system, which I abhor... "The most beautiful experience we can have is the mysterious.

January 1, 2015. Preface For over a decade I have taught an introductory, undergraduate class, "Einstein for Everyone," at the University of Pittsburgh to anyone interested enough to walk through door. With each new offering of the course, I had the chance to find out what content worked and which of my ever so clever pedagogical inventions were failures. At the same time, my lecture notes have evolved. Its content reflects the fact that my interest lies in history and philosophy of science and that I teach in a Department of History and Philosophy of Science. This text owes a lot to many. i i i
