Relativity Timeline 300 BC to 2005

**306-283 B.C.**of Greece known as the '**Euclid***father of geometry'*creates the most printed literary work of all time, '*The Elements*'.**1285-1349**fights**William of Ockham (also Occam)***papal power*and proposes '*plurality should not be assumed without necessity' (Pluralitas non est ponenda sine neccesitate),*now known as Occam's razor.**1564-1642**born in Pisa, Italy distinguished himself as a musician, mathematician, astronomer and natural philosopher. One of his works, entitled ‘*Galileo Galilei**Dialogue Concerning the Two Chief Systems of the World - Ptolemaic and Copernican, 1632’*, actually saw him tried by the Inquisition. His study of mechanics led to a description of uniform motion referred to as the Galilean transformations.**1768-1830**studied a wide range of topics encompassing sunspots, tides and the weather. His work*Jean-Baptiste Fourier**'The Analytical Theory of Heat'*(*Théorie analytique de la chaleur, 1822*) modeled heat conduction with series of sine and cosine functions.**1803-1853**Austrian born mathematician and astronomer describes the perceived change of frequency in light and sound waves is due to the relative motion of the source and the observer*Christian Doppler**(1842).*This effect or Doppler Shift provides one method in finding planets orbiting other stars.**1831-1879**of Scotland publishes his work*James Maxwell**'On a Dynamical Theory of the Electromagnetic Field (1865)'*, and '*A Treatise on Electricity and Magnetism (1873)'*which form the foundation of*Light*.**1858-1947**of Germany proposed that light emanating from matter had energy proportional to it's frequency (i.e.-color).*Max Planck***1864-1909**Though primarily interested in pure mathematics, he is perhaps best known for his non-Euclidean four-dimensional treatment of electrodynamics, which provides a mathematical framework to the prior work of Einstein and Lorentz. '*Hermann Minkowski**Space and Time*' (*Raum und Zeit*, 1907).**1879-1955**publishes a series of diverse papers in 1905 ranging from atomic particles, light waves to light particles. '**Albert Einstein***On the Electrodynamics of Moving Bodies'*('*Zur Elektrodynamik bewegter Körper'*), which was published on June 30, 1905.**1902-1984**Dirac derived a relativistic theory for the electron (1928) and the theory of holes (1930) (later known as positrons). He is also known for his relativitstic treatment of Schrödinger's equation.*Paul Dirac***1960-1970**Lasers improve optical spectroscopy by over a billionfold.**1932-2002**,**Ken Evenson***et. al.*, improved frequency and speed-of-light measurements. (K. M. Evenson, J.S. Wells, F.R. Peterson, B.L. Danielson, G.W. Day, R.L. Barger and J.L. Hall, Phys. Rev. Letters 29, 1346(1972).) This led to a redefinition of the meter in terms of the speed of light c=299,792,458 m/s.**2005**received the 2005 nobel prize in physics. John Hall and Theodor Hänsch were honored for their contributions to the development of laser-based precision spectroscopy. Roy Glauber was recognized for his contribution to the quantum theory of optical coherence in which he described the behavior of light particles known as photons.*Roy Glauber, John "Jan" Hall and Theodor Hänsch***Present**uses Doppler shifted light to derive space-time relativity and various properties of classical and quantum mechanics.**William Harter**
