M. C. Escher Maurits Cornelis Escher (/ˈɛʃər/, Dutch: [ˈmʌurɪts kɔrˈneːlɪs ˈɛʃər] ( ); 17 June 1898 – 27 March 1972), usually referred to as M. C. Escher, was a Dutch graphic artist. He is known for his often mathematically inspired woodcuts, lithographs, and mezzotints. Early life Maurits Cornelis, was born in Leeuwarden, Friesland, in a house that forms part of the Princessehof Ceramics Museum today. He was a sickly child, and was placed in a special school at the age of seven and failed the second grade. Although he excelled at drawing, his grades were generally poor. Later life In 1922, an important year of his life, Escher traveled through Italy (Florence, San Gimignano, Volterra, Siena, Ravello) and Spain (Madrid, Toledo, Granada). In Italy, Escher met Jetta Umiker, whom he married in 1924. In 1935, the political climate in Italy (under Mussolini) became unacceptable to Escher. Works In his early years, Escher sketched landscapes and nature. Circle Limit III, 1959
3C 321 3C 321 is a system of two galaxies rotating around each other. They are notable for showing the first observed galaxy smiting another galaxy with a blast of energy, which is theorized to be from a supermassive black hole at the center of the former galaxy. The larger galaxy, dubbed the "Death Star Galaxy" by NASA astronomers, has an energetic jet directed towards its companion. The discovery was announced by NASA Dec 18 2007. Observation of the enormous jet was possible due to the combined efforts of both space and ground-based telescopes. Tools included NASA's Chandra X-ray Observatory, the Hubble Space Telescope, Spitzer Space Telescope, the Very Large Array-VLA, and the Multi-Element Radio Linked Interferometer Network. References
Joseph Ducreux Joseph, Baron Ducreux (June 26, 1735 – July 24, 1802) was a French portrait painter, pastelist, miniaturist, and engraver, who was a successful portraitist at the court of Louis XVI of France, and resumed his career after the French Revolution. His less formal portraits show an interest in expanding the range of facial expressions beyond those of official portraiture. Life and career Born in Nancy, France, Ducreux may have trained with his father, who was also a painter. In 1769, Ducreux was sent to Vienna in order to paint a miniature of Marie-Antoinette (shown left) before she left the city in 1770 and married Louis XVI of France. At the outbreak of the French Revolution, Ducreux traveled to London. Ducreux had several children. Work Ducreux specialized in portrait painting, and his early portraits were done in pastel, and include those done of the connoisseurs Pierre-Jean Mariette, the Comte de Caylus and Ange-Laurent de la Live de July.

Gomez's Hamburger Gomez's Hamburger is believed to be a young star surrounded by a protoplanetary disk. It was initially identified as a planetary nebula (i.e. an old dying star), and its distance therefore wrongly estimated to be approximately 6500 light-years away from planet Earth. However, recent results suggest that this object is a young star surrounded by a protoplanetary disk whose distance is only around 900 light-years away. It was discovered in 1985 on sky photographs obtained by Arturo Gomez, support technical staff at the Cerro Tololo Inter-American Observatory near Vicuña, Chile. The photos suggested that there was a dark band across the object, but its exact structure was difficult to determine because of the atmospheric turbulence that hampers all images taken from the ground. The star itself has a surface temperature of approximately 10,000 °C (18,000 °F). The "hamburger buns" are light reflecting off dust, and the "petit paté" is the dark band of dust in the middle.
Les Paul Les Paul, de nombre real Lester William Polsfuss (Waukesha, Wisconsin, Estados Unidos, 9 de junio de 1915 - Nueva York, Estado de Nueva York, 13 de agosto de 2009), fue un guitarrista de jazz estadounidense y una de las más importantes figuras en el desarrollo de instrumentos musicales eléctricos y técnicas de grabación. Les Paul fue pionero en el desarrollo de las guitarras de cuerpo macizo con el diseño de los modelos Gibson Les Paul, que adoptaron su nombre, y en la grabación multipista. Su destreza en el manejo de la guitarra y las innovaciones técnicas que introdujo en el instrumento le hicieron ser conocido como «El mago de Waukesha». Biografía[editar] En los años 1930, Les Paul trabajó en Chicago, Illinois en la radio, tocando música jazz. En enero de 1948 Les Paul sufrió un accidente automovilístico, donde voló 50 metros, en el que se lesionó su brazo y codo derechos.

Earth's shadow The Earth's shadow or Earth shadow (also sometimes known as the dark segment) are names for the shadow that the Earth itself casts on its atmosphere. This shadow is often visible from the surface of the Earth, as a dark band in the sky near the horizon. This atmospheric phenomenon can sometimes be seen twice a day, around the times of sunset and sunrise. Whereas the phenomenon of night (a function of being in the shadow of the Earth) is very familiar to all, the effect of the Earth's shadow on the atmosphere is quite often visible in the sky, and yet often goes unrecognized. Assuming the sky is clear, the Earth's shadow is visible in the opposite half of the sky to the sunset or sunrise, and is seen right above the horizon as a dark blue band. Appearance Earth's shadow and Belt of Venus at sunset, looking east from the Marin Headlands just north of San Francisco. At sunrise, the Earth's shadow is seen in a similar way, but in the western sky. Belt of Venus Color
Luigi Russolo Biography Luigi Russolo was perhaps the first noise artist. His 1913 manifesto, L'Arte dei Rumori, translated as The Art of Noises, stated that the industrial revolution had given modern men a greater capacity to appreciate more complex sounds. Russolo found traditional melodic music confining and envisioned noise music as its future replacement. He designed and constructed a number of noise-generating devices called Intonarumori and assembled a noise orchestra to perform with them. A performance of his Gran Concerto Futuristico (1917) was met with strong disapproval and violence from the audience, as Russolo himself had predicted. At first the art of music sought purity, limpidity and sweetness of sound. Russolo and Marinetti gave the first concert of Futurist music, complete with intonarumori, in April 1914 (causing a riot). The program comprised four "networks of noises" with the following titles: Intonarumori reconstruction See also Further reading

Luna 2, the first object made on Earth to reach the surface of the Moon. A moon landing is the arrival of a spacecraft on the surface of the Moon. The United States' Apollo 11 was the first manned mission to land on the Moon, on 20 July 1969. There have been six manned U.S. landings (between 1969 and 1972) and numerous unmanned landings, with no soft landings happening from 1976 until 14 December 2013. Unmanned landings The Soviet Union performed the first hard (unpowered) Moon landing in 1959 with the Luna 2 spacecraft, a feat the U.S. duplicated in 1962 with Ranger 4. The Soviet Union achieved the first unmanned lunar soil sample return with the Luna 16 probe on 24 September 1970.
Raymond Robinson (Green Man) Raymond "Ray" Robinson (October 29, 1910 – June 11, 1985) was a severely disfigured man whose years of nighttime walks made him into a figure of urban legend in western Pennsylvania. Robinson was so badly injured in a childhood electrical accident that he could not go out in public without fear of creating a panic, so he went for long walks at night. Local residents, who would drive along his road in hopes of meeting him, called him The Green Man or Charlie No-Face. They passed on tales about him to their children and grandchildren, and people raised on these tales are sometimes surprised to discover that he was a real person who was liked by his family and neighbors. Robinson was eight years old when he was injured by an electrical line on the Morado Bridge, outside of Beaver Falls, while attempting to view a bird's nest. Robinson became a local myth in the Pittsburgh area, and his real story was obscured by urban legend.
Lunokhod programme The Lunokhod mission diagram. Soviet moonrover Development Parabolic dish TNA-400 and abandoned NIP-10 Lunokhod's original primary mission was the survey of sites for later manned landings and lunar bases. At least four complete vehicles were constructed, with the serial numbers 201, 203, 204 and 205. Lunokhod 201 After years of secret engineering development and training, the first Lunokhod (vehicle 8ЕЛ№201) was launched on February 19, 1969. Lunokhod 1 Lunokhod 1 robot vehicle After the destruction of the original Lunokhod, Soviet engineers began work immediately on another lunar vehicle. Luna 17 was launched on November 10, 1970 at 14:44:01 UTC. The spacecraft soft-landed on the Moon in the Sea of Rains on November 17, 1970 at 03:47 UTC. To be able to work in vacuum a special fluoride based lubricant was used for the mechanical parts and the electric motors (one in each wheel hub) were enclosed in pressurised containers.

Genie (feral child) Genie (born 1957) is the pseudonym of a feral child who was the victim of extraordinarily severe abuse, neglect and social isolation. Her circumstances are recorded prominently in the annals of abnormal child psychology. Born in Arcadia, California, United States, Genie's father kept her locked alone in a room from the age of 20 months to 13 years, 7 months, almost always strapped to a child's toilet or bound in a crib with her arms and legs completely immobilized. During this time she was never exposed to any significant amount of speech, and as a result she did not acquire a first language during childhood. Her abuse came to the attention of Los Angeles child welfare authorities on November 4, 1970. In the first several years after Genie's life and circumstances came to light, psychologists, linguists and other scientists focused a great deal of attention on Genie's case, seeing in her near-total isolation an opportunity to study many aspects of human development.
Luna 2 Luna 2 site is near the right of the image, close to the Apollo 15 landing site Launch was scheduled for September 9, but the Blok I core stage was shut down after it failed to reach full thrust at ignition. The booster was removed from the pad and replaced by a different vehicle, delaying the flight by three days. Luna 2, like Luna 1, took a direct path to the Moon with a journey time of around 36 hours. This was dictated by the fact that the Earth-Moon gravitational system forced it to follow a curved trajectory, and launch had to occur from the side of the Earth opposite the Moon. Luna 2 was similar in design to Luna 1, a spherical spacecraft with protruding antennas and instrument parts. Van Allen Radiation Belt Luna 2 showed time variations in the electron flux and energy spectrum in the Van Allen radiation belt.

Victor of Aveyron Victor of Aveyron (c. 1788 – 1828) was a French feral child who was found in 1800 after apparently spending the majority of his childhood alone in the woods. Upon his discovery, his case was taken up by a young physician, Jean Marc Gaspard Itard, who worked with the boy for five years and gave him his name, Victor. Itard was interested in determining what Victor could learn. He devised procedures to teach the boy words and recorded his progress. Early life Victor is estimated to have been born around 1788. Study Victor of Aveyron Shortly after Victor was found, a local abbot and biology professor, Pierre Joseph Bonnaterre, examined him. Influence of the Enlightenment The Enlightenment caused many thinkers, including naturalists and philosophers, to believe human nature was a subject that needed to be redefined and looked at from a completely different angle.
