1 Nothing Is New Under the Sun ! Prof. Dr. Dr. Carlo Rubbia Scientific
Nothing is new under the Sun ! Prof. Dr. Dr. Carlo Rubbia Scientific Director, Institute for Advanced Sustainability Studies e.V. Potsdam, Germany -Accompanying document to Prof. Rubbia’s keynote address during the 3rd Dii Desert Energy Conference (Berlin, November 7-9 2012). The beginning of the practical use of solar power goes back some 23 centuries ago with Archimedes of Syracuse, (287 BC to 212 BC) in sunny Sicily. Mathematician, physicist, engineer, inventor and astronomer, he has been one of the leading scientists of the classical antiquity. The written work of Archimedes has not survived as well as that of Euclid, and seven of his treatises are known to have existed only through references made to them by other authors. Only few details are known. However, the relatively few copies of Archimedes' written work that survived through the Middle Ages were an influential source of ideas for scientists during the Renaissance. His contributions in mathematics have been immense: the initiator of the infinitesimals, anticipating the modern calculus of the ratio between the square of the radius and the area of a circle, the quadrature of a parabola as the solution of an infinite series, the centre of gravity of geometric figures and so on. The Fields Medal, the equivalent of the Nobel in mathematics carries his portrait along with a carving illustrating his proof on the sphere and the cylinder. The inscription is a quote attributed to him, which reads in Latin: "Transire suum pectus mundoque potiri" (Rise above oneself and grasp the world). Among his advances in physics are the foundations of hydrostatics, refraction and parabolic concentration of light, statics and an explanation of the principle of the lever, where he said “Give me a place to stand on, and I will move the Earth”. -

Box 50005, SE-104 05 Stockholm, Sweden Phone: +46 8 673 95 00, Fax: +46 8 15 56 70, E-mail: [email protected], Website: www.kva.se Asymptotic Freedom and Quantum ChromoDynamics: the Key to the Understanding of the Strong Nuclear Forces The Basic Forces in Nature We know of two fundamental forces on the macroscopic scale that we experience in daily life: the gravitational force that binds our solar system together and keeps us on earth, and the electromagnetic force between electrically charged objects. Both are mediated over a distance and the force is proportional to the inverse square of the distance between the objects. Isaac Newton described the gravitational force in his Principia in 1687, and in 1915 Albert Einstein (Nobel Prize, 1921 for the photoelectric effect) presented his General Theory of Relativity for the gravitational force, which generalized Newton’s theory. Einstein’s theory is perhaps the greatest achievement in the history of science and the most celebrated one. The laws for the electromagnetic force were formulated by James Clark Maxwell in 1873, also a great leap forward in human endeavour. With the advent of quantum mechanics in the first decades of the 20th century it was realized that the electromagnetic field, including light, is quantized and can be seen as a stream of particles, photons. In this picture, the electromagnetic force can be thought of as a bombardment of photons, as when one object is thrown to another to transmit a force. -

Standard Model. What will the lectures cover? Issues concerning the Standard Model of particle physics: Even though we call it a model it is actually the candidate for the ’theory’ of the fundamental particles and interactions among them! Built, brick by brick, over the last 50-60 years, combining information from a lot of different types of experiments and many many innovative theoretical ideas. The basic mathematical framework is that of quantum field theories (QFT) which possess some special properties (symmetries). Some aspects of these will be covered in lectures by Prof. Deredinger. July 11 - July 15, 2011. CERN Summer Student Program. Standard Model. What will the lectures cover? Using this information I intend then to cover the following : • How did we find out about the fundamental constituents and inter- actions among them. • How did we arrive at an understanding of the symmetries and hence a gauge theory description of the same: how was the SM built? • What is the significance of the different families of quarks and leptons: flavour physics. • What is the piece of the SM still left to be checked and how does the theory guide us about how and where to look for the missing piece.

Who Got Moseley's Prize?
Chapter 4 Who Got Moseley’s Prize? Virginia Trimble1 and Vera V. Mainz*,2 1Department of Physics and Astronomy, University of California, Irvine, Irvine, California 92697-4575, United States 2Department of Chemistry, University of Illinois at Urbana-Champaign, Urbana, Illinois 61802, United States *E-mail: [email protected]. Henry Gwyn Jeffreys Moseley (1887-1915) made prompt and very skilled use of the then new technique of X-ray scattering by crystals (Bragg scattering) to solve several problems about the periodic table and atoms. He was nominated for both the chemistry and physics Nobel Prizes by Svante Arrhenius in 1915, but was dead at Gallipoli before the committees finished their deliberations. Instead, the 1917 physics prize (announced in 1918 and presented on 6 June 1920) went to Charles Glover Barkla (1877-1944) “for discovery of the Röntgen radiation of the elements.” This, and his discovery of X-ray polarization, were done with earlier techniques that he never gave up. Moseley’s contemporaries and later historians of science have written that he would have gone on to other major achievements and a Nobel Prize if he had lived. In contrast, after about 1916, Barkla moved well outside the scientific mainstream, clinging to upgrades of his older methods, denying the significance of the Bohr atom and quantization, and continuing to report evidence for what he called the J phenomenon. This chapter addresses the lives and scientific endeavors of Moseley and Barkla, something about the context in which they worked and their connections with other scientists, contemporary, earlier, and later. © 2017 American Chemical Society Introduction Henry Moseley’s (Figure 1) academic credentials consisted of a 1910 Oxford BA with first-class honors in Mathematical Moderations and a second in Natural Sciences (physics) and the MA that followed more or less automatically a few years later. -

Deconstruction: Standard Model Discoveries
deconstruction: standard model discoveries elementary types of particles form the basis for the theoretical framework known as the Sixteen Standard Model of fundamental particles and forces. J.J. Thomson discovered the electron in 1897, while scientists at Fermilab saw the first direct interaction of a tau neutrino with matter less than 10 years ago. This graphic names the 16 particle types and shows when and where they were discovered. These particles also exist in the form of antimatter particles, with the same mass and the opposite electric charge. Together, they account for about 300 subatomic particles observed in experiments so far. The Standard Model also predicts the Higgs boson, which still eludes experimental detection. Experiments at Fermilab and CERN could see the first signals for this particle in the next couple of years. Other funda- mental particles must exist, too. The Standard Model does not account for dark matter, which appears to make up 83 percent of all matter in the universe. 1968: SLAC 1974: Brookhaven & SLAC 1995: Fermilab 1979: DESY u c t g up quark charm quark top quark gluon 1968: SLAC 1947: Manchester University 1977: Fermilab 1923: Washington University* d s b γ down quark strange quark bottom quark photon 1956: Savannah River Plant 1962: Brookhaven 2000: Fermilab 1983: CERN νe νμ ντ W electron neutrino muon neutrino tau neutrino W boson 1897: Cavendish Laboratory 1937 : Caltech and Harvard 1976: SLAC 1983: CERN e μ τ Z electron muon tau Z boson *Scientists suspected for several hundred years that light consists of particles.
