He enters to the National university in 1922 and is received with the contest of aggregation of Physical sciences in 1925. He is then stock-broker of studies to the Faculty of Science to prepare a thesis of Doctorat.
He is doctor are Mathématiques in 1927 (the Hydrodynamique and the theory Cinétique of gases), then science physics in 1928 (molecular theory of the diffusion of the light by the fluids, thesis prepared at the laboratory of Charles Fabry). He is then in charge of the course of the Fondation Peccot with the senior research worker named Collège de France then in 1932. He becomes university lecturer of physics to the Faculty of Science of Clermont-Ferrand in 1939 then on October 1st, 1939 university lecturer of experimental mechanics of the fluids to the Faculty of Science of Paris.
During the Second world war, it belonged to a resistant group. At the time of a particularly dangerous mission, it flies away towards the England on a small aircraft. There, it joined De Gaulle which appoints it research director of the free French Naval forces. It is interested particularly in detection by the Radar S English of strong radio transmissions of the sun (not during a scientific work, but like interfering with the purely military use of the radar).
After the war, Rocard returns to France, and begins its true career. In 1945, he becomes full professor of physics and director of the physics laboratory of ENS, succeeding Georges Bruhat. He sets up at it a site of radio Astronomie; managing even to put the hand on “2 German mirrors of radar of type Wurzburg , each of 7,5 m in diameter” essential to start such a project. Using its contacts of time of war, he manages to reach the ultra secrecy Research center of the National marine of Marcoussis, the Essonne. He is also the inventor of the first lamp radio with indirect heating, and made studies on the radio-landing without visibility.
Starting from 1947, he becomes scientific adviser for the military programs with ECA, after the setting well off Frederic Joliot-Curie regarded as a too influential member of the PCF. In 1951, he is scientific leader of the programs which will lead France to the control of the nuclear armament. He is to some extent the father of the bombs has and H-bombs French.
In 1952, in spite of work pioneers in radio astronomy carried out in France, it becomes obvious that others use more powerful instruments face to which the French will not be able to align themselves. Rocard vigorously supports the project and the Minister of education main road grants 25 franc million to the National university. A place is found for the observatory of radio astronomy to Nançay (Cher), famous site because of its 32 radio telescope S aligned in full field. Under its impulse, the physics laboratory of the ENS in Paris starts in 1955 the construction of the Laboratoire of the linear accelerator with Orsay, the Essonne, to give to the scientists their accelerating first of electrons.
In parallel, he will also begin the research varied on:
- Semiconductor S,
- stability with the wind of the Bridge of Tancarville;
- sensitivity of the Waterfinder S (as from 1957);
- the UFO S and the Project Blue Book in 1966 (it belonged to the Invisible Collège of Josef Allen Hynek).
In May 1963, the scientific review of popularization Science and Vie in its number 548, devotes an article titrated to him “ Après of the years of polemic, Science and Life affirms it " Yes the Radiesthésie is true! " ”. The author of this file, Charles-Gregoire Maubert, after having interviewed Yves Rocard, as follows explains the reasons for which the divining rod starts to move at certain times: “(...) the water which filters in porous environments, under the action of a difference in pressure, fact, to be born from the potentials electrokinetic S, by a Effet Quincke, well-known since 1850. These potentials make circulate in the ground of the electric currents. Moreover, in many cases, of the additional phenomena, related to the presence of water, cause in the ground of the correlative potential differences often much more important. ” the experiments of Yves Rocard which were then remade by the Comité Para with a more rigorous method (randomized, Double blind man) were negative.
In 1973, at 70 years, it leaves the physics laboratory of the National university and Jean Brossel takes his succession with the direction. In 1981, in the last part of its life, Rocard concentrates its interest on the low values of the Magnétisme and the Biomagnétisme. It undertakes research on the sensitivity of the waterfinders, able to detect a variation of magnetism about the milligauss. That will be worth the lightnings of the rationalist Union in particular to him, and an armchair, almost reserved will cost him, with the Academy of Science which will reproach him its “research far too strange”. Something of Yves Rocard, impassioned Sourcellerie, exists in the character of the Professor Tryphon Tournesol when one sees it using his famous Pendule.
Rocard dies in 1992 at Paris, year when the French company of physics “in homage to the whole of its work” will create the price which bears its name, and “rewards a technology transfer between a public research laboratory and a private company”.
“ You know, magnetism and the hypnotizers will survive, as well as the radiesthesists and the waterfinders. If science could all explain and medicine, all to cure, it would be done by it magnetism and “sensors” of waves but - and it is so much better -, it is not the case. 30 years ago, when I started to interest me in the waterfinders, who are, in fact, of the radiesthesists, and of the hypnotizers, my scientific colleagues thought that the Sénescence gained me but you will note that I have still good foot good eye and I answer your questions. The hypnotizers and the radiesthesists exist because they obtain undeniable results . They will exist as a long time as they will continue to obtain these results. ” Interview of Pr Yves Rocard by Christian Becant (Re-examined Dowsing, January 2004).
