Astronomy
Astronomy () is a natural science that studies astronomical object, celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and chronology of the Universe, evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Egyptian astronomy, Egyptians, Chinese astronomy, Chinese, Maya civilization, Maya, and many anc ...

William Thomson, 1st Baron Kelvin
William Thomson, 1st Baron Kelvin, (26 June 182417 December 1907) was a British mathematician, mathematical physicist and engineer born in Belfast. Professor of Natural Philosophy at the University of Glasgow for 53 years, he did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics, and did much to unify the emerging discipline of physics in its contemporary form. He received the Royal Society's Copley Medal in 1883, was its president 1890–1895, and in 1892 was the first British scientist to be elevated to the House of Lords. Absolute temperatures are stated in units of kelvin in his honour. While the existence of a coldest possible temperature ( absolute zero) was known prior to his work, Kelvin is known for determining its correct value as approximately −273.15 degrees Celsius or −459.67 degrees Fahrenheit. The Joule–Thomson effect is also named in his honour. He worked closely with mathematics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Daytime And Evening Exercises In Astronomy, For Schools And Colleges (IA Cu31924031322104)
Daytime as observed on Earth is the period of the day during which a given location experiences natural illumination from direct sunlight. Daytime occurs when the Sun appears above the local horizon, that is, anywhere on the globe's hemisphere facing the Sun. In direct sunlight the movement of the sun can be recorded and observed using a sundial that casts a shadow that slowly moves during the day. Other planets and natural satellites that rotate relative to a luminous primary body, such as a local star, also experience daytime, but this article primarily discusses daytime on Earth. Characteristics Approximately half of Earth is illuminated at any time by the Sun. The area subjected to direct illumination is almost exactly half the planet; but because of atmospheric and other effects that extend the reach of indirect illumination, the area of the planet covered by either direct or indirect illumination amounts to slightly more than half the surface. The hemisphere of Earth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Machpelah Cemetery (Le Roy, New York)
Machpelah Cemetery is located on North Street in Le Roy, New York, United States. It was opened in the mid-19th century and expanded since then. Graves from other, smaller burial grounds around Le Roy have been added. It was listed on the National Register of Historic Places in 2007, one of two cemeteries in Genesee County with that distinction. It was originally built and laid out as a rural cemetery, with a parklike setting on the banks of Oatka Creek. In the early 20th century its design philosophy changed, when a large mausoleum to local businessman Orator Francis Woodward, who in his last years made a fortune developing Jell-O into a bestselling dessert, was built in the southern section of the cemetery near his factory. The architect hired by the family to lay out the section was influenced by the City Beautiful movement, giving that area a more orderly cast.

Prohibition
Prohibition is the act or practice of forbidding something by law; more particularly the term refers to the banning of the manufacture, storage (whether in barrels or in bottles), transportation, sale, possession, and consumption of alcoholic beverages. The word is also used to refer to a period of time during which such bans are enforced. History Some kind of limitation on the trade in alcohol can be seen in the Code of Hammurabi (c. 1772 BCE) specifically banning the selling of beer for money. It could only be bartered for barley: "If a beer seller do not receive barley as the price for beer, but if she receive money or make the beer a measure smaller than the barley measure received, they shall throw her into the water." In the early twentieth century, much of the impetus for the prohibition movement in the Nordic countries and North America came from moralistic convictions of pietistic Protestants. Prohibition movements in the West coincided with the advent of women's su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
