Amavasya is the Indic name for a new-moon. The word Amavasya is common to many Indian languages especially Sanskrit, Hindi, Marathi and Gujarati.

In 1692 Edmund Halley (in a paper printed in Philosophical Transactions of Royal Society of London) put forth the idea of Earth consisting of a hollow shell about 500 miles thick, with two inner concentric shells around an innermost core, corresponding to the diameters of the planets Venus, Mars, and Mercury respectively. Halley's construct was a method of accounting for the (flawed) values of the relative density of the Earth and the Moon that had been given by Sir Isaac Newton, in Principia (1687).“Sir Isaac Newton has demo ...

Creationism - Scientific critique of creationism. All forms of Creationism incorporate some theological content, but they have varied considerably over time in the degree to which they incorporate scientific evidence. Since the origins of modern geology in the 18th and 19th centuries, theories of creationism have become increasingly separated from mainstream science. Many modern forms of creationism, particularly Young Earth Christian creationism, were created to defend the literal interpretation of the biblical ...

Thuban (α Dra / α Draconis / Alpha Draconis) is a star (or star system) in the constellation of Draco. Due to the precession of Earth's rotational axis, it was the naked-eye star closest to the north pole from some time prior to 3000 B.C. until 1900 B.C., when it was superseded by Beta Ursae Minoris. It was closest to the pole in 2700 B.C.: a mere 10 seconds of arc away (1/180th the width of the full Moon). Thuban is just barely fourth magnitude, so it cannot be seen from light-polluted areas. Even though Thuban is the alpha ...

Ancient astronaut theory is a term used to describe the theories of ancient extraterrestrial contact being involved in some way with the origin or development of human culture.

These theories often claim that human beings are either the descendants or creations of aliens who landed on Earth millennia ago — ...

In physics, acceleration (symbol: a) is defined as the rate of change (or time derivative) of velocity. It is thus a vector quantity with dimension length/time². In SI units, this is metre/second². Acceleration - Explanation. To accelerate an object is to change its velocity in relation to time. In this strict scientific sense, acceleration can have positive and negative values – respectively called acceleration (velocity is increased) and deceleration (or retardation -- velocity is decrea ...

A Rayleigh wave moves across a surface. As it passes, a surface particle moves in a circle or ellipse in the direction of propagation. If one measures particles deeper in the material, the particles move in smaller ellipses, then reach a "no movement" depth, a "node." Below this, harmonics of the Raleigh wave move particles in regions that alternate elliptical motion with nodes of no-movement. The maximum distance that Raleigh waves move particles (the amplitu ...

The Permian is a geologic period that extends from about 299.0 Ma to 248.0 Ma (million years before the present; ICS 2004). It is the last period of the Palaeozoic Era. As with most older geologic periods, the strata that define the Permian are well identified, but the exact date of the period's start is uncertain by a few million years. The Permian follows the Carboniferous (Pennsylvanian in North America) and is followed by the Triassic. The end of the period is marked by a major extinction event, called the Permian-Triassic extinct ...

Adrien Auzout (January 28th, 1622–May 23rd, 1691) was a French astronomer. He was born in Rouen, France, the son of a clerk in the court of Rouen. His educational background is unknown. In 1664–1665 made observations of comets, and argued in favor of their following elliptical or parabolic orbits. (In this he was opposed by his rival Johannes Hevelius.) Adrien was briefly a member of the Académie Royale des Sciences from 1666 to 1668, and a founding member of the french Royal Obseratory. (He may have left the academy due t ...

The Wiphala is a square emblem, commonly used as a flag, representing the native peoples of the central Andes and Amazon region of South America. It is composed of a 7-by-7 square patchwork in seven colours, arranged diagonally.
