First edition of Wilhelm Wien's highly influential paper on the phenomenon of radiation, also known as Wien's displacement law. Wien followed Ludwig Boltzmann's approach when incorporating electrodynamics and thermodynamics in investigating radiation and its characteristics. ""He argued that if a system reaches the same temperature by the increase of temperature or by the adiabatic compression of the volume containing heat radiation, it should yield the same energy distribution. Considering also the Doppler effect of the radiation, Wien arrived at an expression for energy distribution that states that the product of temperature and the wave length is a constant"". (Mathew Chandrankunnel, Philosophy of physics, 2000, 4 p).Wien's empirical observations functioned as a starting point for Max Planck who wanted prove the theoretical foundation for Wien's, wishing thus to justify the entropy law. Today Wien's approximation is also known as Wien-Planck law.This phenomenon was coined ""Wien's displacement law"" because the energy density curve is displaced correspondingly to the temperature"" it implies that the hotter an object is, the shorter the wavelength at which it will release most of its radiation. Wien's description of radiation awarded him the Nobel Prize in Physics in 1911. Wien's constant is today used in a wide range of different aspects of physics, e.g. cosmic microwave background, and the determination of how much energy is emitted from a light bulb.

First appearance of Wien's importent paper in which he shows that the cathode rays are particles, that their velocity is about a third to that of light and he establish the ratio between the mass and the charge.In the paper are ""described the experiments by which Wien determined the properties of the canal rays. The firstpart of the paper conatins a description of observations on the cathode rays, made with a Lenard Tube, in which the cathode rays passed through an aluminium window into an extension of the tube where as high a rarefaction as possible was maintained. The magnetic and electrostatic deflexions of a narrow cathode stream were observed and Wien concludes that it is proved by his investigation that the cathode rays which pass through the windoww carry with them strong negative charges.""(Magie ""Souce Book in Physics"", p. 597 ff.).Wien was awarded the 1911 Nobel Prize for physics for his discoveries regarding laws governing the radiation of heat.
