Timeline of electromagnetism and classical optics *424 BC Aristophanes “lens” is a glass globe filled with water.(Seneca says that it can be used to read letters ”no matter how small or dim”) *3rd century BC Euclid is the first to write about reflection and refraction and notes that light travels in straight lines * 130 [...]
Early scientific history of crystals and X-rays X-rays were discovered by Wilhelm Conrad Röntgen in 1895, just as the studies of crystal symmetry were being concluded. Physicists were initially uncertain of the nature of X-rays, although it was soon suspected (correctly) that they were waves of electromagnetic radiation, in other words, another form of light. [...]
Contemporary research in physics can be broadly divided into condensed matter physics; atomic, molecular, and optical physics; particle physics; astrophysics; geophysics and biophysics. Some physics departments also support research in Physics education. Since the twentieth century, the individual fields of physics have become increasingly specialized, and today most physicists work in a single field for [...]
In 1953 Albert Einstein wrote to the Cleveland Physics Society on the occasion of a commemoration of the Michaelson–Morley experiment. In that letter he wrote: : What led me more or less directly to the special theory of relativity was the conviction that the electromotive force acting on a body in motion in a magnetic [...]
The discovery of the electron by J. J. Thomson was the first indication that the atom had internal structure. At the turn of the 20th century the accepted model of the atom was J. J. Thomson’s “plum pudding” model in which the atom was a large positively charged ball with small negatively charged electrons embedded [...]
For astronomers, a total solar eclipse forms a rare opportunity to observe the corona (the outer layer of the Sun’s atmosphere). Normally this is not visible because the photosphere is much brighter than the corona. According to the point reached in the solar cycle, the corona may appear small and symmetric, or large and fuzzy. [...]
For much of the history of observational astronomy, almost all observation was performed in the visual spectrum with optical telescopes. While the Earth’s atmosphere is relatively transparent in this portion of the electromagnetic spectrum, most telescope work is still dependent on seeing conditions and air transparency, and is generally restricted to the night time. The [...]
