Winter Paralympic
The Winter Paralympic Games is an international multi-sport event where athletes with physical disabilities compete in snow and ice sports. The event includes athletes with mobility impairments, amputations, blindness, and cerebral palsy. The Winter Paralympic Games are held every four years directly following the Winter Olympic Games and (since 1992) hosted in the same city. The International Paralympic Committee (IPC) oversees the Games. Medals are awarded in each event: with gold for first place, silver for second, and bronze for third, following the tradition that the Olympic Games began in 1904. The Winter Paralympics began in 1976 in Örnsköldsvik, Sweden. Those Games were the first Paralympics that featured athletes other than those in wheelchairs. The Games have expanded and grown, including the Summer Paralympic Games, to become part of the largest international sporting event after the Olympics. Given their expansion, the need for a very specific classification sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhodes Scholarship
The Rhodes Scholarship is an international postgraduate award for students to study at the University of Oxford, in the United Kingdom. Established in 1902, it is the oldest graduate scholarship in the world. It is considered among the world's most prestigious international scholarship programs. Its founder, Cecil John Rhodes, wanted to promote unity among English-speaking nations and instill a sense of civic-minded leadership and moral fortitude in future leaders, irrespective of their chosen career paths. Initially restricted to male applicants from countries that are today within the Commonwealth, Germany and the United States, the scholarship is now open to applicants from all backgrounds and genders around the world. Since its creation, controversy has surrounded its initial exclusion of women, its historical failure to select black Africans, and Cecil Rhodes's own standing as a British imperialist. Rhodes Scholars have achieved distinction as politicians, academics, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Ocean Acoustic Tomography
Ocean acoustic tomography is a technique used to measure temperatures and currents over large regions of the ocean. On ocean basin scales, this technique is also known as acoustic thermometry. The technique relies on precisely measuring the time it takes sound signals to travel between two instruments, one an acoustic source and one a receiver, separated by ranges of . If the locations of the instruments are known precisely, the measurement of time-of-flight can be used to infer the speed of sound, averaged over the acoustic path. Changes in the speed of sound are primarily caused by changes in the temperature of the ocean, hence the measurement of the travel times is equivalent to a measurement of temperature. A change in temperature corresponds to about change in sound speed. An oceanographic experiment employing tomography typically uses several source-receiver pairs in a moored array that measures an area of ocean. Motivation Seawater is an electrical conductor, ...

Chief Operating Officer
A chief operating officer or chief operations officer, also called a COO, is one of the highest-ranking executive positions in an organization, composing part of the "C-suite". The COO is usually the second-in-command at the firm, especially if the highest-ranking executive is the chairperson and CEO. The COO is responsible for the daily operation of the company and its office building and routinely reports to the highest-ranking executive—usually the chief executive officer (CEO). Responsibilities and similar titles Unlike other C-suite positions, which tend to be defined according to commonly designated responsibilities across most companies, a COO's job tends to be defined in relation to the specific CEO with whom they work, given the close working relationship of these two individuals. The selection of a COO is similar in many ways to the selection of a vice president or chief of staff of the United States: power and responsibility structures vary in government and priva ...

Facebook
Facebook is an online social media and social networking service owned by American company Meta Platforms. Founded in 2004 by Mark Zuckerberg with fellow Harvard College students and roommates Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes, its name comes from the face book directories often given to American university students. Membership was initially limited to Harvard students, gradually expanding to other North American universities and, since 2006, anyone over 13 years old. As of July 2022, Facebook claimed 2.93 billion monthly active users, and ranked third worldwide among the most visited websites as of July 2022. It was the most downloaded mobile app of the 2010s. Facebook can be accessed from devices with Internet connectivity, such as personal computers, tablets and smartphones. After registering, users can create a profile revealing information about themselves. They can post text, photos and multimedia which are shared with any ...

Giant Slalom
Giant slalom (GS) is an alpine skiing and alpine snowboarding discipline. It involves skiing between sets of poles ("gates") spaced at a greater distance from each other than in slalom but less than in Super-G. Giant slalom and slalom make up the technical events in alpine ski racing. This category separates them from the speed events of Super-G and downhill. The technical events are normally composed of two runs, held on different courses on the same ski run. Course The vertical drop for a GS course must be for men, and for women. The number of gates in this event is 56–70 for men and 46–58 for women. The number of direction changes in a GS course equals 11–15% of the vertical drop of the course in metres, 13–18% for children. As an example, a course with a vertical drop of would have 33–45 direction changes for an adult race. Speed Although giant slalom is not the fastest event in skiing, on average a well-trained racer may reach average speeds of . Equipment ...

Slalom Skiing
Slalom is an alpine skiing and alpine snowboarding discipline, involving skiing between poles or gates. These are spaced more closely than those in giant slalom, super-G, super giant slalom and Downhill (ski competition), downhill, necessitating quicker and shorter turns. Internationally, the sport is contested at the FIS Alpine World Ski Championships, and at the Olympic Winter Games. History The term slalom comes from the Morgedal/Seljord dialect of Norwegian language, Norwegian word "slalåm": "sla", meaning "slightly inclining hillside", and "låm", meaning "track after skis". The inventors of modern skiing classified their trails according to their difficulty. ''Slalåm'' was a trail used in Telemark by boys and girls not yet able to try themselves on the more challenging runs. ''Ufsilåm'' was a trail with one obstacle (''ufse'') like a jump, a fence, a difficult turn, a gorge, a cliff (often more than high) and more. ''Uvyrdslåm'' was a trail with several obstacle ...
