  2. Born coordinates - Wikipedia

    en.wikipedia.org/wiki/Born_coordinates

    To motivate the Born chart, we first consider the family of Langevin observers represented in an ordinary cylindrical coordinate chart for Minkowski spacetime. The world lines of these observers form a timelike congruence which is rigid in the sense of having a vanishing expansion tensor.

  3. Extended Wulff constructions - Wikipedia

    en.wikipedia.org/wiki/Extended_Wulff_constructions

    Extended Wulff constructions refers to a number of different ways to model the structure of nanoparticles as well as larger mineral crystals, and as such can be used to understand both the shape of certain gemstones or crystals with twins.as well as in other areas such as how nanoparticles play a role in the commercial production of chemicals using heterogeneous catalysts.

    These two results, if combined, prove some form of time dilation. 1932 – John Cockcroft and Ernest Walton prove the mass–energy equivalence via a nuclear reaction. 1933 – Dayton Miller conducts an improved form of the Michelson–Morley experiment, claiming to contradict special relativity. [32]

  5. Born rigidity - Wikipedia

    en.wikipedia.org/wiki/Born_rigidity

    Born rigidity is satisfied if the orthogonal spacetime distance between infinitesimally separated curves or worldlines is constant, [7] or equivalently, if the length of the rigid body in momentary co-moving inertial frames measured by standard measuring rods (i.e. the proper length) is constant and is therefore subjected to Lorentz contraction in relatively moving frames. [8]

    The Vac-u-form, was a toy invented by Eddy Goldfarb and released by Mattel in the 1960s around 1961 with the trademark filed on October 8, 1962. [1] Based on the industrial process of vacuum forming, a rectangular piece of plastic was clamped in a holder and heated over a metal plate. When the plastic was soft, the holder was swung to the other ...

    Vergence-accommodation conflict (VAC), also known as accommodation-vergence conflict, is a visual phenomenon that occurs when the brain receives mismatching cues between vergence and accommodation of the eye.

  8. Electron-beam physical vapor deposition - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_physical...

    Electron-beam physical vapor deposition, or EBPVD, is a form of physical vapor deposition in which a target anode is bombarded with an electron beam given off by a charged tungsten filament under high vacuum. The electron beam causes atoms from the target to transform into the gaseous phase.

    Gershon Kurizki was born in 1952 in Vilnius, Lithuania (then the Soviet Union). [2] He immigrated to Israel with his family in 1960. After completing his B.Sc. and M.Sc. in physics at the Technion in 1979, he moved in 1980 to the University of New Mexico, USA, where he obtained his Ph.
