| Născut în Transilvania, la Sibiu, pe 25 iunie 1894, Hermann Oberth face parte dintr-o familie de sași transilvăneni cu mare deschidere spre noile cuceriri științifice. El frecventează gimnaziul umanist din Sighişoara, cunoscut ca Şcoala din Deal. Liceanul de 12 ani citește cu înfrigurare cărțile lui Jules Verne: De la Pământ la Lună şi Călătorie în jurul Lunii, care îi trezesc curiozitatea și dorința de a cunoaște cosmosul, determinându-l să caute soluții practice pentru a ajunge în spațiu. Astfel, în 1908, Oberth, în vârstă de numai 14 ani, găseşte soluţia: racheta. De atunci înainte, drumul vieții sale este predestinat: el devine cel care descoperă racheta spațială și viața lui se dedică în întregime deschiderii unei largi perspective spre spațiile infinite, în folosul semenilor lui. În mod incontestabil, el este o personalitate universală care nu poate fi revendicată de un popor sau o țară anume, și totuși, putem spune cu mâna pe inimă că el și-a extras seva și geniul din pământul și spiritualitatea Transilvaniei, făcând primii pași ai vieții pe pământ românesc. Activitatea desfășurată de el în Mediaș și Sighișoara ca profesor de fizică şi de matematică, de inventator, a pus amprenta asupra culturii transilvane a începutului de secol 20. În onoarea lui Hermann Oberth, cel care a făcut primul pas către Lună, instituții de învățământ și străzi din Transilvania au primit numele său. Și suntem mândri că, deși de-a lungul vieții sale drumul l-a purtat pe renumitul „părinte al navigației spațiale” prin multe locuri de pe Pământ, în cele din urmă, patria sa rămâne România.

Death: Dec. 29, 1989 Profession (s): German physicist, mathematician Publications: The Rocket into Planetary Space (1923) Remembered for: One of the fathers of rocketry and astronautics, along with Tsiolkovsky and Goddard. Quotation: „To make available for life every place where life is possible. Rejected rocket theory At the close of World War I, Oberth returned Germany to attend the University of Heidelberg, studying physics rather than medicine. In 1922, he submitted his dissertationThe sun gun or heliobeam is a theoretical orbital weapon, which makes use of a concave mirror mounted on a satellite, to concentrate sunlight onto a small area at the Earth’s surface, destroying targets or killing through heat. In 1929, the German physicist Hermann Oberth developed plans for a space station from which a 100-metre-wide concave Hermann Oberth was born on June 25, 1894, in Hermannstadt, Austria-Hungary (now Sibiu, Romania). He was a German scientist who was one of the founders of modern astronautics and is sometimes called “the Father of Space Travel.”. He is often compared to Robert Goddard of the United States and Konstantin Tsiolkovsky of the Soviet Union. 6/1923 to 1929 Permalink Image Source: upload.wikimedia.org In 1923 Romanian-German physicist Hermann Oberth published Die Rakete zu den Planetenräumen in Munich and Berlin at the press of R. Oldenbourg. This book began as a doctoral thesis on the rocket in interplanetary space which Oberth submitted to the University of Heidelberg in 1922.

January 1963 to July 1965 – 1923 – Hermann Oberth published Die Rakete zu den Planetenraumen (The Rocket into Planetary Space), which contained the first serious proposal for a manned space station to appear in scientific literature rather than fiction. Oberth’s study presented The idea of using space mirrors was first proposed by German physicist Hermann Oberth in 1929 for a much diabolic purpose. Oberth wanted to create a weapon, using a 100-meter-wide concave mirror, that could reflect sunlight onto a concentrated point on earth capable of incinerating whole cities and even boil oceans. Hermann Oberth was a close friend and professional colleague of von Braun’s. In fact, he called Oberth, a star aeronautical engineer, “my teacher”. Oberth is often referred to as the “German Father of Rocketry”. Oberth made an intriguing comment about the extraterrestrial subject: Oberth left West Germany for Switzerland in 1948, with his family. They secretly went to Italy in 1950, under false names, so that Oberth could work for the Marina Militare, on an equally secret anti-aircraft missile project. Oberth’s contract was terminated in early 1953 as a result of the limited success enjoyed by his team. Compare Oberth’s and Menger’s craft to Carr’s OTC-X1. The Electric Spaceship, by Hermann Oberth The design of this Vril Engine shares similarities with the design of the OTC-X1. Hermann Oberth de Hans Barth descarcă cartea pdf, epub, mobi. The maneuver, originally suggested by Hermann Oberth, improves efficiency considerably for a wide range of missions of interest in space exploration and scientific investigation. A clear delineation of when the maneuver is more effective is given, as are methods to extract the most advantage when using the maneuver. The Hermann Oberth Space Travel Museum ( Hermann-Oberth-Raumfahrt-Museum, or Hermann-Oberth-Museum for short) is a museum of space technology in the Franconian city of Feucht in Bavaria, Germany. It commemorates the life work of the famous visionary and rocket pioneer Hermann Oberth. Exhibits include a Kumulus rocket and a Cirrus rocket, which The sun gun or heliobeam is a theoretical orbital weapon, which makes use of a concave mirror mounted on a satellite, to concentrate sunlight onto a small area at the Earth’s surface, destroying targets or killing through heat.
