He worked as an examiner at the in, and he later said of a co-worker there, that he 'could not have found a better sounding board for his ideas in all of Europe'. In addition to co-workers and the other members of the self-styled 'Olympian Academy' (Solovine and Habicht), his wife, may have had some influence on Einstein's work but how much is unclear. Through these papers, Einstein tackles some of the era's most important physics questions and problems.
In 1900, a lecture titled 'Nineteenth-Century Clouds over the Dynamical Theory of Heat and Light', by, suggested that physics had no satisfactory explanations for the results of the and for radiation. As introduced, special relativity provided an account for the results of the Michelson-Morley experiments.

Einstein's theories for the photoelectric effect extended the which had developed in his successful explanation of black body radiation. Despite the greater fame achieved by his other works, such as that on, it was his work on the which won him his in 1921: 'For services to theoretical physics and especially for the discovery of the law of the photoelectric effect.' The Nobel committee had waited patiently for experimental confirmation of special relativity; however none was forthcoming until the experiments of Ives and Stilwell (1938), (1941) and Rossi and Hall (1941).
Advertisements Photoelectric effect The paper, 'On a Viewpoint Concerning the Production and Transformation of ', proposed the idea of energy quanta. This idea, motivated by 's earlier derivation of the law of, assumes that can be absorbed or emitted only in discrete amounts, called. Einstein states, Energy, during the propagation of a ray of, is not continuously distributed over steadily increasing spaces, but it consists of a finite number of localised at, moving without dividing and capable of being absorbed or generated only as. In explaining the, the hypothesis that consists of discrete packets, as Einstein illustrates, can be directly applied to, as well. The idea of light quanta contradicts the wave theory of light that follows naturally from 's for behavior and, more generally, the assumption of of energy in physical systems. A profound formal difference exists between the theoretical concepts that physicists have formed about gases and other ponderable bodies, and Maxwell's theory of electromagnetic processes in so-called empty space.
While we consider the state of a body to be completely determined by the positions and velocities of an indeed very large yet finite number of atoms and electrons, we make use of continuous spatial functions to determine the electromagnetic state of a volume of space, so that a finite number of quantities cannot be considered as sufficient for the complete determination of the electromagnetic state of space. This leads to contradictions when applied to the phenomena of emission and transformation of light. According to the view that the incident light consists of energy quanta., the production of cathode rays by light can be conceived in the following way. The body's surface layer is penetrated by energy quanta whose energy is converted at least partially into kinetic energy of the electrons. The simplest conception is that a light quantum transfers its entire energy to a single electron. Einstein noted that the photoelectric effect depended on the wavelength, and hence the frequency of the light. At too low a frequency, even intense light produced no electrons.
However, once a certain frequency was reached, even low intensity light produced electrons. He compared this to Planck's hypothesis that light could be emitted only in packets of energy given by hf, where h is Planck's constant and f is the frequency. He then postulated that light travels in packets whose energy depends on the frequency, and therefore only light above a certain frequency would bring sufficient energy to liberate an electron. Even after experiments confirmed that Einstein's equations for the were accurate, his explanation was not universally accepted., in his 1922 Nobel address, stated, 'The hypothesis of light-quanta is not able to throw light on the nature of radiation.' By 1921, when Einstein was awarded the Nobel Prize and his work on photoelectricity was mentioned by name in the award citation, some physicists accepted that the equation ( ) was correct and light quanta were possible.
In 1923, 's helped more of the scientific community to accept this formula. The theory of light quanta was a strong indicator of, a fundamental principle of. A complete picture of the theory of photoelectricity was realized after the maturity of quantum mechanics. Brownian motion The article ' ('On the Motion of Small Particles Suspended in a Stationary Liquid, as Required by the Molecular Kinetic Theory of Heat') delineated a model of. In this paper it will be shown that, according to the molecular kinetic theory of heat, bodies of a microscopically visible size suspended in liquids must, as a result of thermal molecular motions, perform motions of such magnitudes that they can be easily observed with a microscope. It is possible that the motions to be discussed here are identical with so-called Brownian molecular motion; however, the data available to me on the latter are so imprecise that I could not form a judgment on the question.
Brownian motion generates expressions for the of particles. Using the kinetic theory of fluids, which at the time was controversial, the article established the phenomenon, which was lacking a satisfactory explanation even decades after the first observation, provided empirical evidence for the reality of the. It also lent credence to, which had been controversial at that time, as well. Before this paper, atoms were recognized as a useful concept, but physicists and chemists debated whether atoms were real entities. Einstein's statistical discussion of atomic behavior gave experimentalists a way to count atoms by looking through an ordinary microscope., one of the leaders of the anti-atom school, later told that he had been convinced of the existence of atoms by Einstein's complete explanation of Brownian motion.

Anni mirabiles) is a phrase that means 'wonderful year', 'miraculous year' or 'amazing year'. This term was originally used to refer to the year 1666, and today is used to refer to several years during which events of major importance are remembered. Prior to this, however, Thomas Dekker used the phrase mirabilis annus in his 1603 pamphlet The Wonderful Year, 'Wherein is shewed the picture of London lying sick of the plague.'
Main article: According to the, the first known written usage of the Latin phrase ' is as the title of a poem composed by English poet about the events of 1666. The phrase ' annus mirabilis' translates as 'wonderful year' or 'year of miracles'.
In fact, the year was beset by great calamity for England (including the ), but Dryden chose to interpret the absence of greater disaster as miraculous intervention by God, as '666' was then regarded as the, and the year 1666 expected by some to be particularly disastrous. In addition to this, the English fleet defeated a Dutch fleet in the, for a great victory at sea. (However, in 1667 the Dutch burned several major warships of the English fleet in the and was forced to sue for peace.) Isaac Newton.
