John Gill (climber)
John Gill (born 16 Feb 1937) is an American mathematician who has achieved recognition for his rock-climbing. Many climbers consider him the father of modern bouldering.Sherman, John (1994). ''Stone Crusade: A Historical Guide to Bouldering in America'', American Alpine Club Press. Early life and professional career As a child, Gill lived in several southern U.S. cities, including Atlanta, Georgia, where he graduated from Bass High School in 1954. He attended Georgia Tech from 1954 to 1956, and graduated from the University of Georgia with a degree in mathematics in 1958. He entered the U.S. Air Force as a second lieutenant, and also attended a special graduate meteorology program at the University of Chicago in 1958 and 1959. He was assigned to Glasgow AFB in Montana until 1962, and resigned from the USAF Reserves as a captain several years later.Ament, Pat (1998). ''John Gill:Master of Rock.

Möbius Transformation
In geometry and complex analysis, a Möbius transformation of the complex plane is a rational function of the form f(z) = \frac of one complex variable ''z''; here the coefficients ''a'', ''b'', ''c'', ''d'' are complex numbers satisfying ''ad'' − ''bc'' ≠ 0. Geometrically, a Möbius transformation can be obtained by first performing stereographic projection from the plane to the unit two-sphere, rotating and moving the sphere to a new location and orientation in space, and then performing stereographic projection (from the new position of the sphere) to the plane. These transformations preserve angles, map every straight line to a line or circle, and map every circle to a line or circle. The Möbius transformations are the projective transformations of the complex projective line. They form a group called the Möbius group, which is the projective linear group PGL(2,C). Together with its subgroups, it has numerous applications in mathematics and physics. Möbius transfor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meditation
Meditation is a practice in which an individual uses a technique – such as mindfulness, or focusing the mind on a particular object, thought, or activity – to train attention and awareness, and achieve a mentally clear and emotionally calm and stable state. Meditation is practiced in numerous religious traditions. The earliest records of meditation (''dhyana'') are found in the Upanishads, and meditation plays a salient role in the contemplative repertoire of Jainism, Buddhism and Hinduism. Since the 19th century, Asian meditative techniques have spread to other cultures where they have also found application in non-spiritual contexts, such as business and health. Meditation may significantly reduce stress, anxiety, depression, and pain, and enhance peace, perception, self-concept, and well-being. Research is ongoing to better understand the effects of meditation on health (psychology, psychological, neurology, neurological, and cardiovascular) and other areas. Etymol ...

Disciples Of Gill
Pat Ament (born September 3, 1946) is an American rock climber, filmmaker, musician, and artist who lives in Fruita, Colorado. Noted for first ascents in the 1960s and 1970s, he is the author of many articles and books. Climbing career Ament began climbing in 1958, and by the mid 1960s had established the first 5.11 climbs in Colorado (''Supremacy Crack'') and Yosemite (''Center Route on the Slack''). A college gymnast, he was a dedicated boulderer and put up many challenging problems on Flagstaff Mountain in Boulder, Colorado, elsewhere in Colorado and in Yosemite Valley. His climbing and bouldering companions over the years have included Royal Robbins, Bob Kamps, Don Whillans Donald Desbrow Whillans (18 May 1933 – 4 August 1985) was an English rock climber and mountaineer. He climbed with Joe Brown and Chris Bonington on many new routes, and was considered the technical equal of both. Early life Born and brought ..., Tom Higgins, John Gill, and Layton Kor. Clim ...

Alpinist (magazine)
''Alpinist'' is a quarterly United States, American magazine focused on outdoor literature, mountain literature and mountaineering ascents worldwide. History and profile ''Alpinist'' was founded in 2002 and was originally published out of Jackson, Wyoming. It was resurrected in 2009, and is now based in Jeffersonville, Vermont. The magazine often focuses on "fast and light" ascents and advocates a rigorous clean-climbing style (not leaving gear behind).

Chalk
Chalk is a soft, white, porous, sedimentary carbonate rock. It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor. Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the Dover cliffs on the Kent coast of the English Channel. Chalk is mined for use in industry, such as for quicklime, bricks and builder's putty, and in agriculture, for raising pH in soils with high acidity. It is also used for " blackboard chalk" for writing and drawing on various types of surfaces, although these can also be manufactured from other carbonate-based minerals, or gypsum. Description Chalk is a fine-textured, earthy type of limestone distinguished by its light color, softness, and high porosity. It is composed mostly of tiny fragments of the calcite shells or skeletons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gymnastics
Gymnastics is a type of sport that includes physical exercises requiring balance, strength, flexibility, agility, coordination, dedication and endurance. The movements involved in gymnastics contribute to the development of the arms, legs, shoulders, back, chest, and abdominal muscle groups. Gymnastics evolved from exercises used by the ancient Greeks that included skills for mounting and dismounting a horse, and from circus performance skills. The most common form of competitive gymnastics is artistic gymnastics (AG), which consists of, for women (WAG), the events floor, vault, uneven bars, and beam; and for men (MAG), the events floor, vault, rings, pommel horse, parallel bars, and horizontal bar. The governing body for gymnastics throughout the world is the Fédération Internationale de Gymnastique (FIG). Eight sports are governed by the FIG, which include gymnastics for all, men's and women's artistic gymnastics, rhythmic gymnastics, trampolining (including double mini-t ...

Traditional Climbing
Traditional climbing (or Trad climbing) is a style of rock climbing in which the climber places all the necessary protection gear required to arrest any falls as they are climbing, and then removes it when the pitch is complete (often done by the second/follow-on climber). Traditional bolted aid climbing means the bolts were placed while on lead and/or with hand drills (the bolts tend to be much farther apart than for sport climbs). Traditional climbing carries a higher level of risk than bolted sport climbing, as the climber may not have placed the safety equipment correctly while trying to ascend the route; for some of the world's hardest climbs (e.g. '' Realization/Biographie''), there may not be sufficient cracks or features in the rock that can accept protection gear, and the climb can only be safely attempted by bolting as a sport climb. Overview Characterizing climbing as ''traditional'' distinguishes it from bolted climbing—either trad bolted or sport climbing ...

University Of Southern Colorado
Colorado State University Pueblo (CSU Pueblo) is a public university in Pueblo, Colorado. It is a member of the Colorado State University System (CSU System) and a Hispanic-Serving Institution (HSI). History 1933 to 1959 The idea for starting a college in Pueblo was initially proposed in 1926, when a bill was put before the state Senate to begin a four-year school in the city. The bill was defeated by one vote. In the years following the Great Depression, the idea for a college in Pueblo was revived through the efforts of a local school teacher at Centennial High School, Eric T. Kelly. At the time, Pueblo's primary employer, steelmaker Colorado Fuel & Iron Corp., was no longer hiring, drought and dust storms were plaguing all of Southern Colorado and the city still was trying to recover from the devastating floods of 1921. Kelly organized a committee that was composed of several local business leaders to discuss the possibility of getting a college started, among them Frank ...
