  • De Nobelprijzen Komen Eraan!
    De Nobelprijzen komen eraan! De Nobelprijzen komen eraan! In de loop van volgende week worden de Nobelprijswinnaars van dit jaar aangekondigd. Daarna weten we wie in december deze felbegeerde prijzen in ontvangst mogen gaan nemen. De Nobelprijzen zijn wellicht de meest prestigieuze en bekende academische onderscheidingen ter wereld, maar waarom eigenlijk? Hoe zijn de prijzen ontstaan, en wie was hun grondlegger, Alfred Nobel? Afbeelding 1. Alfred Nobel.Alfred Nobel (1833-1896) was de grondlegger van de Nobelprijzen. Volgende week is de jaarlijkse aankondiging van de prijswinnaard. Alfred Nobel Alfred Nobel was een belangrijke negentiende-eeuwse Zweedse scheikundige en uitvinder. Hij werd geboren in Stockholm in 1833 in een gezin met acht kinderen. Zijn vader, Immanuel Nobel, was een werktuigkundige en uitvinder die succesvol was met het maken van wapens en stoommotoren. Immanuel wou dat zijn zonen zijn bedrijf zouden overnemen en stuurde Alfred daarom op een twee jaar durende reis naar onder andere Duitsland, Frankrijk en de Verenigde Staten, om te leren over chemische werktuigbouwkunde. In Parijs ontmoette bron: https://www.quantumuniverse.nl/de-nobelprijzen-komen-eraan Pagina 1 van 5 De Nobelprijzen komen eraan! Alfred de Italiaanse scheikundige Ascanio Sobrero, die drie jaar eerder het explosief nitroglycerine had ontdekt. Nitroglycerine had een veel grotere explosieve kracht dan het buskruit, maar was ook veel gevaarlijker om te gebruiken omdat het instabiel is. Alfred raakte geinteresseerd in nitroglycerine en hoe het gebruikt kon worden voor commerciele doeleinden, en ging daarom werken aan de stabiliteit en veiligheid van de stof. Een makkelijk project was dit niet, en meerdere malen ging het flink mis.

  • A Laser (From the Acronym Light Amplification by Stimulated Emission of Radiation) Is an Optical Source That Emits Photons in a Coherent Beam
    LASER A laser (from the acronym Light Amplification by Stimulated Emission of Radiation) is an optical source that emits photons in a coherent beam. The verb to lase means "to produce coherent light" or possibly "to cut or otherwise treat with coherent light", and is a back- formation of the term laser. Laser light is typically near-monochromatic, i.e. consisting of a single wavelength or color, and emitted in a narrow beam. This is in contrast to common light sources, such as the incandescent light bulb, which emit incoherent photons in almost all directions, usually over a wide spectrum of wavelengths. Laser action is explained by the theories of quantum mechanics and thermodynamics. Many materials have been found to have the required characteristics to form the laser gain medium needed to power a laser, and these have led to the invention of many types of lasers with different characteristics suitable for different applications. The laser was proposed as a variation of the maser principle in the late 1950's, and the first laser was demonstrated in 1960. Since that time, laser manufacturing has become a multi- billion dollar industry, and the laser has found applications in fields including science, industry, medicine, and consumer electronics.

Abstract. Soviet policy-makers, in order to aid and abet industrialisation, seem to have chosen science as an agent for development. Soviet science, mainly through the Academy of Sciences of the USSR, was driving the Soviet industrial development and a key element of the preparation of human capital through social programmes and politechnisation of the society.

RAMSEY Any opinions expressed in this memoir are those of the author and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 2008 NATIONAL ACADEMY OF SCIENCES WASHINGTON, D.C. POLYKARP KUSCH January 26, 1911–March 20, 1993 BY NORMAN F . RAMSEY OLYKARP KUSCH, A GREAT physicist, teacher, and Nobel laure- Pate, died in Dallas, Texas, at age 82 on March 20, 1993. Kusch was a pioneer in molecular beam magnetic resonance experiments; he and his associates, with unprecedented high accuracy, measured many atomic and nuclear spins, magnetic dipole moments, electric quadrupole moments, and atomic hyperfine structure separations. Kusch and his associates also made the first direct measurement of the magnetic moment of the electron, which showed that it was consistent with the previously observed anomalous hyperfine separation in atomic hydrogen and with J. Schwinger’s then-new relativistic quantum electrodynamics (QED). Polykarp Kusch was born in Blankenburg, Germany, on January 26, 1911, the son of John Mathias Kusch, a Lutheran missionary, and Henrietta van der Haas. The family emigrated to the United States in 1912, and Kusch became a naturalized U.S. citizen in 1922. He attended grade school in the Mid- west, and started his college education as a chemistry major at Case Institute of Technology in Cleveland, Ohio, shifting to physics before receiving his bachelor of science degree in 1931. He then moved to the University of Illinois, where in 1933 he received an M.S.

  • RUSSIAN SCIENCE and TECHNOLOGY STRUCTURE There Are Around 4000 Organizations in Russia Involved in Research and Development with Almost One Million Personnel
    RUSSIAN SCIENCE AND TECHNOLOGY STRUCTURE There are around 4000 organizations in Russia involved in research and development with almost one million personnel. Half of those people are doing scientific research. It is coordinated by Ministry of industry, science and technologies, where strategy and basic priorities of research and development are being formulated. Fundamental scientific research is concentrated in Russian Academy of Sciences, which now includes hundreds of institutes specializing in all major scientific disciplines such as mathematics, physics, chemistry, biology, astronomy, Earth sciences etc. The applied science and technology is mainly done in Institutions and Design Bureaus belonging to different Russian Ministers. They are involved in research and development in nuclear energy (Ministry of atomic energy), space exploration (Russian aviation and space agency), defense (Ministry of defense), telecommunications (Ministry of communications) and so on. Russian Academy of Sciences Russian Academy of Sciences is the community of the top-ranking Russian scientists and principal coordinating body for basic research in natural and social sciences, technology and production in Russia. It is composed of more than 350 research institutions. Outstanding Russian scientists are elected to the Academy, where membership is of three types - academicians, corresponding members and foreign members.
