FRANKREICH ALESSANDRO VOLTA BEI NAPOLEON

Volta shows electricity to Napoleon. 19th-century artwork of Italian physicist Count Alessandro Volta (1745-1827) demonstrating electricity to the French Emperor Napoleon Bonaparte (1769-1821). Volta invented his voltaic pile (battery) in 1800 and gave demonstrations to Napoleon and others in 1801. Volta is at left, with Napoleon at centre right, turning to comment to his physician Jean-Nicolas Corvisart (1755-1821). Napoleon was impressed and conferred numerous honours on Volta. This artwork is from the title page of volume 1 of 'A Manual of Electricity, Magnetism, and Meteorology' (1841) by Irish author Dionysius Lardner.

PHYSIK HIGGS BOSON

Higgs boson. Artwork representing the elementary particle known as the Higgs boson (centre). The existence of this hypothetical particle is predicted by the Standard Model of particle physics. It is a product of the Higgs field that is used to explain why particles have mass. A series of experiments to detect this particle were carried out in 2010 and 2011 at the Large Hadron Collider (LHC) particle accelerator at the European particle physics laboratory (CERN). Analysis of the data has narrowed the range of possible properties of this particle, but definitive results are not expected until the end of 2012.

PHYSIK HIGGS BOSON

Computer simulation of a Higgs boson event in the L3 detector at CERN, the European centre for particle physics near Geneva. L3 is one of 4 giant particle detectors at the LEP electron-positron collider. The Higgs boson is a particle postulated by physicist Peter Higgs & is a cornerstone of the "electroweak" theory uniting the electromagnetic & weak forces. Its discovery is one of the hopes of LEP physicists. The display represents an event in which an electron-positron annihilation produces a Higgs particle & a Z particle, both of which decay into other particles whose paths are represented by the coloured tracks. The boxes represent the energy deposited in L3's hadron calorimeter. (KEYSTONE/SCIENCE PHOTO LIBRARY/PHILIPPE PLAILLY/SCIENCE PHOTO LIBRARY)

Graphene transistor. Physicist Andre Geim holds a graphene transistor in a pair of tweezers. Graphene is composed of a single layer of carbon atoms that is both flexible and very strong. It conducts electrons faster than silicon and could one day replace silicon in applications such as nanometre (billionths of a metre) sized electronics, cheap and efficient solar panels, transparent window coatings and miniature sensing technologies. Graphene was discovered by Geim in 2004. (KEYSTONE/SCIENCE PHOTO LIBRARY/JAMES KING-HOLMES/SCIENCE PHOTO LIBRARY)

PHYSIK HIGGS BOSON

Simulated detection of Higgs boson. Computer simulation of an event in which the decay of a Higgs boson particle produces four muons (red tracks). The muons, along with countless other particles (blue tracks), are produced in a head-on collision between two protons. The Higgs boson is a localised clustering in the Higgs Field. This field permeates space, and local distortions of the Higgs Field are thought to be the way that particles gain mass. This image shows how the Higgs boson might be seen in the CMS detector on the Large Hadron Collider at CERN, the European particle physics laboratory. (KEYSTONE/SCIENCE PHOTO LIBRARY/DAVID PARKER)

Andre Geim (born 1958), Russian born physicist. Professor Geim, seen here holding a model of graphene, is Director of the Centre for Mesoscience and Nanotechnology at Manchester University, UK. His notable achievements include, the development of a material with similar adhesive properties to the feet of gecko lizards, the first magnetic levitation of a live animal (frog), and the discovery of graphene, a single layer of carbon atoms with many potential technology applications.Photographed in 2009.

PHYSIK PETER HIGGS

British theoretical physicist Professor Peter Higgs (b. 1929). In 1964, Higgs predicted the existence of a new type of fundamental particle, commonly called the Higgs boson. This particle is required by many of the current Grand Unified Theories (or GUTs) which hope to explain three of the fundamental forces (electromagnetism, the weak & the strong nuclear forces) in a single unified theory. The Higgs boson is yet to be detected experimentally, but it is one of the main challenges of high-energy particle accelerators now being built. Higgs is professor of theoretical physics at Edinburgh University. This photograph was taken at his office in Edinburgh in 1988. (KEYSTONE/SCIENCE PHOTO LIBRARY/DAVID PARKER/SCIENCE PHOTO LIBRARY)
