Royal Astronomical Society - Royal Astronomical Society The Royal Astronomical Society (RAS) began as the Astronomical Society of London in 1820 to support astronomical research (mainly carried on at the time by 'gentleman astronomers' rather than professionals). It became the Royal Astronomical Society in 1831 on receiving its Royal Charter from William IV. A Supplemental Charter in 1915 opened up the fellowship to women. It is the UK adhering organisation to the International Astronomical Union and a member of the Science Council.

It currently publishes two world-leading primary research journals, MNRAS in astronomy and (in association with the Deutsche Geophysikalische.
List of reference tables - List of reference tables You usually find a collection of reference tables in the back of almanacs, dictionaries and encyclopedias (or an index of them, if they're scattered throughout the work). As these tables appear, please add them to this index. What we have in mind is listings or tabular information for quick reference, not narrative articles.

Lists of articles by category - Lists of articles by category This list provides a broad overview of all Wikipedia articles by category. None of these are yet comprehensive or up-to-date, but filling in or creating these lists will create an easy way to track articles by their categories, as well as creating an implicit to-do list of topics for which articles have not yet been written. If a "List of" page does not yet exist, or is empty, a link is provided to the next best overview of articles in that category. Please create "List of" pages for each of these categories, and provide a link to each page. Since these categories span broad disciplines of knowledge, these lists complement those found on the list of reference tables, which cover very narrow, specific topics..

Hermann Weyl - for quantum mechanics. He also showed how to use exponential sums in diophantine approximation, with his criterion for uniform distribution mode 1, which was fundamental step in analytic number theory. Weyl's own comment, although half a joke, sums up his personality. My work always tried to unite the truth with the beautiful, but when I had to choose one or the other, I usually chose the beautiful.

Great Pyramid of Giza - the top. The most precisely cut stones were reserved for the outside. Once in place their corners were smoothened to give an almost shiny outer appearance of the pyramid. Paranormal interest and encoded numbers As a structure of impressive construction and mystery, the great pyramid has attracted the attention of occultists (as have many other aspects of ancient Egyptian culture). The great pyramid and the Sphinx are often alleged to have been built with mysterious ancient forces rather than human labor and/or by Atlanteans, extraterrestrials, or other mysterious creators. It has been alleged that the dimensions and details, properly interpreted, provide prophecies of events in modern times. This theory was first proposed in the 1800s by John Taylor, who believed the pyramid had actually been constructed by the biblical Noah. Charles.
Aberration of light - Aberration of light Aberration of light (and refered to as Astronomical aberration) is an astronomical phenomenon defined as an apparent motion of the heavenly bodies; the stars describing annually orbits more or less elliptical, according to the latitude of the star; consequently at any moment the star appears to be displaced from its true position. This apparent motion is due to the finite velocity of light, and the progressive motion of the observer with the Earth, as it performs its yearly course about the Sun.

Big Rip - galaxies together. Approximately three months before the end, solar systems will be gravitationally unbound. In the last minutes, stars and planets will come apart, and atoms will be destroyed a fraction of a second before the end of time. The authors of this hypothesis calculate that the end of time would be approximately 3.5×1010 years after the Big Bang, or 2.0×1010 years from now.

Cosmic microwave background radiation - from cosmic inflation as well as various other competing theories, and are available in detail at http://lambda.gsfc.nasa.gov/. A third space mission, Planck, is to be launched in 2007. Unlike the previous two space missions, Planck is a collaboration between NASA and ESA (the European Space Agency). Skeptics Some researchers point out that the Sunyaev-Zel'dovich theory could account for the "concentrations" observed in the radiations's path to the detector from a uniform source. Here the universe was once superheated (nearly 14 billion years ago), the Sunyaev-Zel'dovich Effect's "condenses" the cosmic microwave background by collapsed structures containing baryons. This could mean that the particular original form of the energy contents of the Universe (and it associated conditions) before recombination is uniform (something that the big bang model does not account for fully). See.
Compton effect - and hence all wavelengths. The effect is important in scientific terms because it demonstrates that light cannot be explained purely as a wave phenomenon. Light must behave as if it consists of particles in order to explain the compton effect. The Compton Effect has on occasion been proposed as an alternative explanation for the phenomenon of the Redshift by opponents of the Big Bang theory, although this is not generally accepted because the influence of the Compton Effect would be noticeable in the spectral lines of distant objects and this is not observed. It is also refered to as "Compton scattering" .

Tunguska event - al released a study suggesting that the object had arrived from the direction of the asteroid belt, working from eyewitness accounts, seismic records, and samples from a 1999 expedition to the area. The chief difficulty in the asteroid theory is that a stony object should have produced a large crater where it struck the ground, but no such crater has been found. It has been hypothesized that the passage of the asteroid through the atmosphere caused pressures and temperatures to build up to a point where the asteroid abruptly disintegrated in a huge explosion. The destruction would have had to be so complete that no remnants of substantial size survived, and the material scattered into the upper atmosphere during the explosion would have caused the skyglows. However, it remains an open.
Star - nighttime sky that twinkle because of the effect of the Earth's atmosphere. The Sun is an exception: it is the only star sufficiently close to Earth to appear as a disc and to provide daylight. Common language does not always reflect this astronomical usage; the term "star" ordinarily does not include the Sun, and sometimes includes the visible planets and even meteors ("shooting stars" or "falling stars"). The nearest star to the earth, apart from the Sun, is Proxima Centauri, which is 40 trillion kilometers away. Light from Proxima Centauri takes 4.2 years to reach Earth. (See light year.) If you took the French TGV, one of the fastest trains, on a trip to Proxima Centauri using its highest recorded speed (515.3 kilometers per hour), it would take you about 8.86.

Pathological science - supporters to critics rises and then falls gradually to oblivion. Possible examples of Pathological science are Chemistry's N rays, Electrochemistry's cold fusion, Chemistry's polywater theory, and Medicine's Homeopathy Mainstream sciences have failed historically to approve of certian sciences till years later and inappropriately label them as "pathological". Examples of sciences that have been misappropriately described as pathological sciences: Linus Pauling's work with vitamins (in particular, vitamin C) [Leading 20th century chemist] C. G. Barkla's J-phenomenon (Barkla's 1917 Nobel Prize in physics was for X-rays; the J-phenomenon is X-ray absorption discontinuities at high frequency) Sir Arthur Eddington's "fundamental theory" (pioneer in theoretical astronomy) Halton Arp astronomical work in the red-shifts phenonomena (rejecting his contempories theories).

Proper motion - themselves. Improper motions are only the apparent motions caused by the motions of Earth (such as precession of the equinoxes and nutation), and by aberration of light. It can also be described as the apparent change of the star on the celestial sphere, and is measured in seconds of arc per year. Barnard's star has the largest proper motion of all stars, moving at 10.3 seconds of arc per year.

Magnetosphere - Magnetosphere The magnetosphere is the region, around an astronomical object, in which the motion of charged particles is dominated by the object's magnetic field. The outer edge of a magnetosphere is called the magnetopause. Earth's magnetosphere Earth's magnetic field has a strength of about 6×10-5 tesla at the poles [1]. Above the surface, this field resembles a dipole with distances of several radii of the Earth (RE). On the sun's side of Earth, the magnetosphere generally extends out to a distance of approximately 10 Earth-radii, while the magnetotail extends several hundred radii in the opposite direction. The magnetosphere behaves something like a compressible fluid because the Earth's magnetic field traps the low-density conductive plasma of the ionosphere. The magnetosphere is made to flap and compress by the solar wind. The.
Interstellar travel - travel to automated systems and awakening unaged at their destination. While manned interstellar travel may prove difficult or impossible to accomplish, manned interplanetary travel (travel between the planets of the solar system) is technically feasible, though economic factors, health and other risks regarding a person's continueous stay in space, and other motivational factors may suspend the achivement. Many scientific papers have been published about related concepts. Given sufficient travel time and engineering work, interstellar travel is certainly possible. NASA has been engaging in research into these topics for several years, and has accumulated a number of theoretical approaches. Among the technologies suggested are nuclear engines (nuclear thermal or nuclear electric, primarily). With any of these technologies interstellar travel times would still be very long compared to a single human lifespan, but.
