Intellectual disability sport classification
Intellectual disability sport classification is a classification system used for disability sport that allows people with intellectual disabilities to fairly compete with and against other people with intellectual disabilities. Separate classification systems exist for the elite athlete with a disability side affiliated with the Paralympic movement and International Sports Federation for Persons with Intellectual Disability (INAS), and the sports for all model affiliated with Special Olympics. People with intellectual disabilities have issues with conceptual skills, social skills and practical skills.
Youth sports
Youth sport (British English) or youth athletics (American English) is any sports event where competitors are younger than adult age, whether children or adolescents. Youth sport includes school sport at primary and secondary level, as well as sport played outside the education system, whether informally or organized. In sports studies and public policy contexts, an age limit of 18 (the age of majority) is usual in discussing "youth sport". Not all sports governing bodies define "youth" as "under-18": while the Youth Olympic Games and the FA Youth Cup are for under-18s, the LEN Junior Water Polo European Championship is for under-17s.
Matt Graham (skier)
Matt Graham (born 23 October 1994) is an Australian freestyle skier. He was a finalist at the 2014 Winter Olympics in Sochi, Russia. Graham joined the Perisher Winter Sports Club mogul program at the age of six, and he has been skiing ever since. Some of his major achievements so far include:   Graham is a graduate of the Central Coast Grammar School, and he has maintained his ties with the school since graduating. He is studying towards his Bachelor of Engineering (Civil) and Bachelor of Business at the University of Newcastle. Matthew Graham was born 23 October 1994, in Narara, a northern suburb of Gosford.
Concussions in Australian sport
Head injuries in sports of any level (junior, amateur, professional) are the most dangerous and sickening kind of injuries that can occur in sport, and are becoming more common in Australian sport. Concussions are the most common side effect of a head injury and are defined as "temporary unconsciousness or confusion and other symptoms caused by a blow to the head." A concussion also falls under the category of Traumatic Brain Injury (TBI). Especially in contact sports like Australian rules football and Rugby issues with concussions are prevalent, and methods to deal with, prevent and treat concussions are continuously being updated and researched to deal with the issue.
Disability sport classification
Disability sports classification is a system that allows for fair competition between people with different types of disabilities. Historically, the process has been by two groups: specific disability type sport organizations that cover multiple sports, and specific sport organizations that cover multiple disability types including amputations, cerebral palsy, deafness, intellectual impairments, les autres and short stature, vision impairments, spinal cord injuries, and other disabilities not covered by these groups. Within specific disability types, some of the major organizations have been CPISRA has for cerebral palsy and head injuries, ISMWSF for spinal cord injuries, ISOD for orthopaedic conditions and amputees, INAS for people with intellectual disabilities, and IBSA for blind and vision impaired athletes.
Richard Lapchick
Richard E. Lapchick is a human rights activist and writer. Lapchick’s life passion was sparked in Germany at the age of 14 while touring the Nazi internment camps of Dachau. Coincidentally, he was in Europe during the 1960 Summer Olympic Games and discovered the tremendous impact sport has to cross all lines, color, creed and religion. Thus, his dream to use sport as a vehicle for social change was born. It reinforced his early experiences witnessing public hostility toward his father when, as the Coach of the New York Knicks, he signed Nat “Sweetwater” Clifton, the first African-American player signed in the NBA in 1950.
Swimming
Swimming is the self-propulsion of a person through fresh or salt water, usually for recreation, sport, exercise, or survival. Locomotion is achieved through coordinated movement of the limbs, the body, or both. Humans can hold their breath underwater and undertake rudimentary locomotive swimming within weeks of birth, as an evolutionary response. Swimming is consistently among top public recreational activities, and in some countries, swimming lessons are a compulsory part of the educational curriculum. As a formalized sport, swimming features in a range of local, national, and international competitions, including every modern summer Olympics.

I have heard of that! Is it true it's best for your joints?

I would imagine so.  In some countries, lessons are even part of a student's education.

College admissions in the United States
College admissions in the United States refers to the process of applying for entrance to institutions of higher education for undergraduate study at one of the nation's 2,675 schools. Generally, the college search begins in the student's eleventh grade of high school with most activity taking place during the twelfth grade, although students at top high schools often begin the process during their tenth grade or earlier. In addition, there are considerable numbers of students who transfer from one college to another, as well as adults older than high school age who apply to college. Millions of high school students apply to college each year.
Super-Poincaré algebra
In theoretical physics, a super-Poincaré algebra is an extension of the Poincaré algebra to incorporate supersymmetry, a relation between bosons and fermions. They are examples of supersymmetry algebras (without central charges or internal symmetries), and are Lie superalgebras. Thus a super-Poincaré algebra is a Z-graded vector space with a graded Lie bracket such that the even part is a Lie algebra containing the Poincaré algebra, and the odd part is built from spinors on which there is an anticommutation relation with values in the even part. The Poincaré algebra describes the isometries of Minkowski spacetime.
Lockheed Martin F-35 Lightning II Canadian procurement
The Lockheed Martin F-35 Lightning II Canadian procurement is a defence procurement project of the Canadian government to purchase Lockheed Martin F-35 Lightning II Joint Strike Fighters for the Royal Canadian Air Force (RCAF), a process started in 1997. The F-35 procurement has been a source of considerable controversy in public policy circles in Canada since the federal government announced its intention to purchase the aircraft in 2010. In April 2012, with the release of a highly critical Auditor General of Canada report on the failures of the government's F-35 program, the procurement was labelled a national "scandal" and "fiasco" by the media.
Education in Germany
The responsibility for the education system in Germany lies primarily with the states ("Länder"), while the federal government plays a minor role. Optional Kindergarten (nursery school) education is provided for all children between one and six years old, after which school attendance is compulsory. The system varies throughout Germany because each state ("Land") decides its own educational policies. Most children, however, first attend Grundschule from the age of six to eleven. German secondary education includes five types of school. The Gymnasium is designed to prepare pupils for higher education and finishes with the final examination "Abitur", after grade 12 or 13.
Yoko Ono
Yoko Ono (born February 18, 1933) is a Japanese multimedia artist, singer, songwriter, and peace activist who is also known for her work in performance art and filmmaking. She performs in both English and Japanese. She is known for being the second wife and widow of singer-songwriter John Lennon of the Beatles. Ono grew up in Tokyo and also spent several formative years in New York City. She studied at Gakushuin, but withdrew from her course after two years and moved to New York in 1953 to live with her family. She spent some time at Sarah Lawrence College and then became involved in New York City's downtown artists scene, which included the Fluxus group.
James Williamson (musician)
James Robert Williamson (born October 29, 1949) is an American guitarist, songwriter, record producer and electronics engineer. He was a member of the iconic proto-punk rock band The Stooges, notably on the influential album "Raw Power" and in the reformed Stooges from 2009 to 2016. Between his stints in music, Williamson worked in Silicon Valley developing computer chips. Most recently he continues as a solo artist. Williamson was born in Castroville, Texas in 1949. His father died while he was young and he moved to San Antonio, Texas around the age of five. He began playing guitar in the 7th grade, while his family were living in Lawton, Oklahoma: "One summer while visiting Texas, I wound up getting a guitar because I thought it was cool.
Muraqaba
Muraqaba (, an Arabic word meaning "to watch over", "to take care of", or "to keep an eye"), is the Sufi word for meditation. It implies that with meditation, a person watches over or takes care of his spiritual heart (or soul), and acquires knowledge about it, its surroundings, and its creator. This form of meditation is common amongst most Sufi orders and is a core concept for many tariqas. Here are the "maqamat" (Arabic: مقامات stages) in which Sufis have broadly categorised their journey of ascension. The categorization is an arbitrary one, and each level is generally further divided into several sublevels.

That's so interesting. My school never had a team or any physical education required by swimming, I think that would be a really good idea.

I agree.  As it relies on the natural buoyancy of the body, everyone should be able to do it.

Scuba diving
Scuba diving is a form of underwater diving where the diver uses a self-contained underwater breathing apparatus (scuba) which is completely independent of surface supply, to breathe underwater. Scuba divers carry their own source of breathing gas, usually compressed air, allowing them greater independence and freedom of movement than surface-supplied divers, and longer underwater endurance than breath-hold divers. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver through a regulator.
Buoyancy compensator (diving)
A buoyancy compensator, also called a buoyancy control device, BC, BCD, stabilizer, stabilisor, stab jacket, wing or ABLJ depending on design, is a piece of diving equipment with an inflatable bladder which is worn by divers to establish neutral buoyancy underwater and positive buoyancy on the surface, when needed. The buoyancy is controlled by adjusting the volume of air in the bladder. The bladder is filled with gas from the diver's primary breathing gas cylinder via a low-pressure hose from the regulator first stage, directly from a small cylinder dedicated to this purpose, or from the diver's mouth through the oral inflation valve.

Buoyancy
In physics, buoyancy () or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. This pressure difference results in a net upwards force on the object. The magnitude of that force exerted is proportional to that pressure difference, and (as explained by Archimedes' principle) is equivalent to the weight of the fluid that would otherwise occupy the volume of the object, i.e.
Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from large gas bags filled with a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen gas, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only used for airships by the United States.
Scuba skills
Scuba skills are the skills required to dive safely using self-contained underwater breathing apparatus, (scuba). Most of these skills are relevant to both open circuit and rebreather scuba, and many are also relevant to surface-supplied diving. Those skills which are critical to the safety of the diver may require more practice than is usually provided during training to achieve reliable long-term proficiency  Some of the skills are generally accepted by recreational diver certification agencies as necessary for any scuba diver to be considered competent to dive without direct supervision, and others are more advanced, though some diver certification and accreditation organizations may consider some of these to also be essential for minimum acceptable entry level competence.
Diving weighting system
Divers wear weighting systems, weight belts or weights to counteract the buoyancy of other diving equipment, such as diving suits and aluminium diving cylinders. The scuba diver must be weighted sufficiently to be slightly negatively buoyant at the end of the dive when most of the breathing gas has been used, and needs to maintain neutral buoyancy at safety or obligatory decompression stops. During the dive, buoyancy is controlled by adjusting the volume of air in the buoyancy compensation device (BCD) and, if worn, the dry suit, in order to achieve neutral or positive buoyancy as needed. The amount of weight required is determined by the maximum overall positive buoyancy of the fully equipped but unweighted diver anticipated during the dive, with an empty buoyancy compensator and normally inflated dry suit.
