Griffith Observatory
Griffith Observatory is an observatory in Los Angeles, California, on the south-facing slope of Mount Hollywood in Griffith Park. It commands a view of the Los Angeles Basin including Downtown Los Angeles to the southeast, Hollywood to the south, and the Pacific Ocean to the southwest. The observatory is a popular tourist attraction with a close view of the Hollywood Sign and an extensive array of space and science-related displays. It is named after its benefactor, Griffith J. Griffith. Admission has been free since the observatory's opening in 1935, in accordance with the benefactor's will. Since its opening, over 9 million people have looked through the 12-inch (30.5 cm) Zeiss refracting scope, making it the most viewed telescope in the world. The space theme prevails in the interior. History On December 16, 1896, of land surrounding the observatory was donated to the City of Los Angeles by Griffith J. Griffith. In his will he donated funds to build an observator ...

Classical Architecture
Classical architecture typically refers to architecture consciously derived from the principles of Ancient Greek architecture, Greek and Ancient Roman architecture, Roman architecture of classical antiquity, or more specifically, from ''De architectura'' (c. 10 AD) by the Roman architect Vitruvius. Variations of classical architecture have arguably existed since the Carolingian Renaissance, and became especially prominent during the Italian Renaissance and the later period known as neoclassical architecture or Classical revival. While classical styles of architecture can vary, they generally share a common "vocabulary" of decorative and structural elements. Across much of the Western world, classical architectural styles have dominated the history of architecture from the Renaissance until World War II. Classical architecture continues to influence contemporary architects. The term ''classical architecture'' can also refer to any architectural tradition that has evolved to a highl ...

Walter Sydney Adams
Walter Sydney Adams (December 20, 1876 – May 11, 1956) was an American astronomer. He is renowned for his pioneering work in spectroscopy. Life and work Adams was born in Antioch, Ottoman Empire, to Lucien Harper Adams and Nancy Dorrance Francis Adams, missionary parents, and was brought to the U.S. in 1885 He graduated from Dartmouth College in 1898, then continued his education in Chicago and in Germany. After returning to the U.S., he began a career in Astronomy that culminated when he became director of the Mount Wilson Observatory. His primary interest was the study of stellar spectra. He worked on solar spectroscopy and co-discovered a relationship between the relative intensities of certain spectral lines and the absolute magnitude of a star. He was able to demonstrate that spectra could be used to determine whether a star was a giant or a dwarf. In 1915 he began a study of the companion of Sirius and found that despite a size only slightly larger than the Earth, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foucault Pendulum
The Foucault pendulum or Foucault's pendulum is a simple device named after French physicist Léon Foucault, conceived as an experiment to demonstrate the Earth's rotation. If a long and heavy pendulum suspended from the high roof above a circular area is monitored over an extended period of time, its plane (geometry), plane of oscillation appears to change spontaneously as the Earth makes its 24-hourly rotation. This effect is greatest at the poles and diminishes with lower latitude until it no longer exists at Earth's equator. The pendulum was introduced in 1851 and was the first experiment to give simple, direct evidence of the Earth's rotation. Foucault followed up in 1852 with a Foucault's gyroscope experiment, gyroscope experiment to further demonstrate the Earth's rotation. Foucault pendulums today are popular displays in science museums and universities. History Foucault was inspired by observing a thin flexible rod on the axis of a lathe, which vibrated in the sam ...

Mars
Mars is the fourth planet from the Sun. It is also known as the "Red Planet", because of its orange-red appearance. Mars is a desert-like rocky planet with a tenuous carbon dioxide () atmosphere. At the average surface level the atmospheric pressure is a few thousandths of Earth's, atmospheric temperature ranges from and cosmic radiation is high. Mars retains some water, in the ground as well as thinly in the atmosphere, forming cirrus clouds, frost, larger polar regions of permafrost and ice caps (with seasonal snow), but no liquid surface water. Its surface gravity is roughly a third of Earth's or double that of the Moon. It is half as wide as Earth or twice the Moon, with a diameter of , and has a surface area the size of all the dry land of Earth. Fine dust is prevalent across the surface and the atmosphere, being picked up and spread at the low Martian gravity even by the weak wind of the tenuous atmosphere. The terrain of Mars roughly follows a north-south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greek Key Pattern
__NOTOC__ A meander or meandros () is a decorative border constructed from a continuous line, shaped into a repeated motif. Among some Italians, these patterns are known as "Greek Lines". Such a design may also be called the Greek fret or Greek key design, although these terms are modern designations; this decorative motif appears much earlier and among Near and Far eastern cultures that are far from Greece. Usually the term is used for motifs with straight lines and right angles and the many versions with rounded shapes are called running scrolls or, following the etymological origin of the term, may be identified as water wave motifs. Meaning of the name On one hand, the name "meander" recalls the twisting and turning path of the Maeander River in Asia Minor (present day Turkey) that is typical of river pathways. On another hand, as Karl Kerenyi pointed out, "the meander is the figure of a labyrinth in linear form". Decorative uses Meanders are common decorative elements ...

Beaux-Arts Architecture
Beaux-Arts architecture ( , ) was the academic architectural style taught at the in Paris, particularly from the 1830s to the end of the 19th century. It drew upon the principles of French neoclassicism, but also incorporated Renaissance and Baroque elements, and used modern materials, such as iron and glass, and later, steel. It was an important style and enormous influence in Europe and the Americas through the end of the 19th century, and into the 20th, particularly for institutional and public buildings. History The Beaux-Arts style evolved from the French classicism of the Style Louis XIV, and then French neoclassicism beginning with Style Louis XV and Style Louis XVI. French architectural styles before the French Revolution were governed by Académie royale d'architecture (1671–1793), then, following the French Revolution, by the Architecture section of the .
