He earned his degree in physics in 1994. Ebert worked from 1995 to 1997 as a consultant at the management consultancy Ogilvy & Mather Dataconsult in Frankfurt am Main. He discovered his talent for satirical revue while giving PowerPoint presentations. [4] From 1997 to 2001 he worked as a strategic planner for the advertising agency Publicis in ...
Shlomo Havlin (Hebrew: שלמה הבלין) (born July 21, 1942) is a professor in the Department of Physics at Bar-Ilan University, Ramat-Gan, Israel.He served as President of the Israel Physical Society (1996–1999), Dean of Faculty of Exact Sciences (1999–2001), chairman, Department of Physics (1984–1988).
Using the upper limit of the cosmological constant, the vacuum energy of free space has been estimated to be 10 −9 joules (10 −2 ergs), or ~5 GeV per cubic meter. [3] However, in quantum electrodynamics , consistency with the principle of Lorentz covariance and with the magnitude of the Planck constant suggests a much larger value of 10 113 ...
The Standard Model of particle physics is the theory describing three of the four known fundamental forces (electromagnetic, weak and strong interactions – excluding gravity) in the universe and classifying all known elementary particles.
Background independence is a condition in theoretical physics that requires the defining equations of a theory to be independent of the actual shape of the spacetime and the value of various fields within the spacetime. In particular this means that it must be possible not to refer to a specific coordinate system—the theory must be coordinate ...
In theoretical physics, background field method is a useful procedure to calculate the effective action of a quantum field theory by expanding a quantum field around a classical "background" value B: = + (). After this is done, the Green's functions are evaluated as a function of the background.
Standard Model of Particle Physics. The diagram shows the elementary particles of the Standard Model (the Higgs boson, the three generations of quarks and leptons, and the gauge bosons), including their names, masses, spins, charges, chiralities, and interactions with the strong, weak and electromagnetic forces.
James Clerk Maxwell FRS FRSE (13 June 1831 – 5 November 1879) was a Scottish physicist and mathematician [1] who was responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon.
