He was the first to investigate the activation energy of molecules by connecting Max Planck's new results concerning light with observations in chemistry. He is also known as the founder of collision theory together with the British scientist William Lewis. While Trautz published his work in 1916, Lewis published it in 1918.
Collision theory is a principle of chemistry used to predict the rates of chemical reactions. It states that when suitable particles of the reactant hit each other with the correct orientation, only a certain amount of collisions result in a perceptible or notable change; these successful changes are called successful collisions.
1911 – Max von Laue writes that special relativity and Lorentz aether theory predict the Sagnac effect, absent in Ritz's ballistic theory or in Stokes's theory of aether drag. [27] 1913 – Georges Sagnac observes the effect named after him, disproving Ritz's ballistic theory or aether drag. However, he favours Lorentz's model and even claims ...
The pivotal question then, was how to unify Maxwell's wave theory of light with its experimentally observed particle nature. The answer to this question occupied Albert Einstein for the rest of his life, [57] and was solved in quantum electrodynamics and its successor, the Standard Model. (See § Quantum field theory and § As a gauge boson ...
The dotted horizontal line represents the set of points regarded as simultaneous with the origin by a stationary observer. This diagram is drawn using the (x, t) coordinates of the stationary observer, and is scaled so that the speed of light is one, i.e., so that a ray of light would be represented by a line with a 45° angle from the x axis.
William Ramsay joined this research topic, and in August they discovered argon. [8] [9] Around 1900 Rayleigh developed the duplex (combination of two) theory of human sound localisation using two binaural cues, interaural phase difference (IPD) and interaural level difference (ILD) (based on analysis of a spherical head with no external pinnae).
1987 – High-temperature superconductivity discovered in 1986, awarded Nobel prize in 1987 (J. Georg Bednorz and K. Alexander Müller) 1989–98 – Quantum annealing; 1993 – Quantum teleportation of unknown states proposed; 1994 – Shor's algorithm discovered, initiating the serious study of quantum computation; 1994–97 – Matrix models ...
Sonoluminescence is the emission of light from imploding bubbles in a liquid when excited by sound. Sonoluminescence was first discovered in 1934 at the University of Cologne . It occurs when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly, emitting a burst of light.
