Stockholm is the capital and largest city of Sweden as well as the largest urban area in Scandinavia. Approximately 990,000 people live in the municipality, with 1.6 million in the urban area, and 2.5 million in the metropolitan area. The city stretches across fourteen islands where Lake Mälaren flows into the Baltic Sea. Outside the city to the east, and along the coast, is the island chain of the Stockholm archipelago. The area has been settled since the Stone Age, in the 6th millennium BC, and was founded as a city in 1252 by Swedish statesman Birger Jarl. It is also the county seat of Stockholm County. For several hundred years, Stockholm was the capital of Finland as well, which was then a part of Sweden. The population of the municipality of Stockholm is expected to reach one million people in 2024.

Particle physics or high energy physics is the study of fundamental particles and forces that constitute matter and radiation. The fundamental particles in the universe are classified in the Standard Model as fermions and bosons. There are three generations of fermions, although ordinary matter is made only from the first fermion generation. The first generation consists of up and down quarks which form protons and neutrons, and electrons and electron neutrinos. The three fundamental interactions known to be mediated by bosons are electromagnetism, the weak interaction, and the strong interaction.

Stockholm University is a public research university in Stockholm, Sweden, founded as a college in 1878, with university status since 1960. With over 33,000 students at four different faculties: law, humanities, social sciences, and natural sciences, it is one of the largest universities in Scandinavia. The institution is regarded as one of the top 100 universities in the world by the Academic Ranking of World Universities (ARWU).

Vetenskap och Folkbildning, abbreviated as VoF, is a Swedish skeptics' association. It was founded in 1982 with the purpose to raise the general public's awareness of scientific methods and results. The association publishes the quarterly journal Folkvett and organises lectures on themes related to science and pseudoscience. Since 1987 the association has annually awarded prizes for "Enlightener of the Year" and "Misleader of the Year".

Skepticism, also spelled scepticism, is a questioning attitude or doubt toward knowledge claims that are seen as mere belief or dogma. For example, if a person is skeptical about claims made by their government about an ongoing war then the person doubts that these claims are accurate. In such cases, skeptics normally recommend not disbelief but suspension of belief, i.e. maintaining a neutral attitude that neither affirms nor denies the claim. This attitude is often motivated by the impression that the available evidence is insufficient to support the claim. Formally, skepticism is a topic of interest in philosophy, particularly epistemology. More informally, skepticism as an expression of questioning or doubt can be applied to any topic, such as politics, religion, or pseudoscience. It is often applied within restricted domains, such as morality, atheism, or the supernatural. Some theorists distinguish "good" or moderate skepticism, which seeks strong evidence before accepting a position, from "bad" or radical skepticism, which wants to suspend judgment indefinitely.

The European Organization for Nuclear Research, known as CERN, is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954, it is based in a northwestern suburb of Geneva, on the France–Switzerland border. It comprises 23 member states, and Israel is currently the only non-European country holding full membership. CERN is an official United Nations General Assembly observer.

The antiproton, p, is the antiparticle of the proton. Antiprotons are stable, but they are typically short-lived, since any collision with a proton will cause both particles to be annihilated in a burst of energy.

The CPLEAR experiment used the antiproton beam of the LEAR facility - Low-Energy Antiproton Ring which operated at CERN from 1982 to 1996 - to produce neutral kaons through proton-antiproton annihilation in order to study CP, T and CPT violation in the neutral kaon system.

In particle physics, a kaon, also called a K meson and denoted K, is any of a group of four mesons distinguished by a quantum number called strangeness. In the quark model they are understood to be bound states of a strange quark and an up or down antiquark.

The Large Hadron Collider (LHC) is the world's largest and highest-energy particle collider. It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and hundreds of universities and laboratories, as well as more than 100 countries. It lies in a tunnel 27 kilometres (17 mi) in circumference and as deep as 175 metres (574 ft) beneath the France–Switzerland border near Geneva.

The European Space Agency is an intergovernmental organisation of 22 member states dedicated to the exploration of space. Established in 1975 and headquartered in Paris, ESA has a worldwide staff of about 2,200 in 2018 and an annual budget of about €4.9 billion in 2023.

The European Astronaut Centre (EAC), is an establishment of the European Space Agency and home of the European Astronaut Corps. It is near to Cologne, Germany, and is subdivided into six separate arms, these being Astronaut Training, Space Medicine, Astronaut Management, Human Exploration of the Moon as part of the Spaceship EAC initiative and Communications. It provides training facilities for European and international partner astronauts, particularly regarding ESA hardware for the ISS such as Columbus and formerly the ATV. The overall European Astronaut Centre organisation is also in charge of the organisation of the training of European astronauts in the centers of other partners, such as the United States, Russia, Canada (Saint-Hubert) or Japan (Tsukuba).

Cologne is the largest city of the German western state of North Rhine-Westphalia (NRW) and the fourth-most populous city of Germany with 1.1 million inhabitants in the city proper and 3.6 million people in the urban region. Centered on the left (west) bank of the Rhine, Cologne is about 35 km (22 mi) southeast of NRW's state capital Düsseldorf and 25 km (16 mi) northwest of Bonn, the former capital of West Germany.

Mir was a space station that operated in low Earth orbit from 1986 to 2001, operated by the Soviet Union and later by Russia. Mir was the first modular space station and was assembled in orbit from 1986 to 1996. It had a greater mass than any previous spacecraft. At the time it was the largest artificial satellite in orbit, succeeded by the International Space Station (ISS) after Mir's orbit decayed. The station served as a microgravity research laboratory in which crews conducted experiments in biology, human biology, physics, astronomy, meteorology, and spacecraft systems with a goal of developing technologies required for permanent occupation of space.

Euromir was an international space programme in the 1990s. Between the Russian Federal Space Agency and the European Space Agency (ESA), it would bring European astronauts to the Mir space station.

Pavel Vladimirovich Vinogradov is a former cosmonaut and commander of the International Space Station. As of January 2023, he has flown into space three times, aboard Mir and the International Space Station, and was one of the top 10 astronauts in terms of total time in space after his third spaceflight. Vinogradov has also conducted seven spacewalks in his cosmonaut career, and holds the record for the oldest person to perform a spacewalk.

STS-116 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Discovery. Discovery lifted off on December 9, 2006, at 20:47:35 EST. A previous launch attempt on December 7 had been canceled due to cloud cover. It was the first night launch of a Space Shuttle since STS-113 in November 2002.

Anders Celsius was a Swedish astronomer, physicist and mathematician. He was professor of astronomy at Uppsala University from 1730 to 1744, but traveled from 1732 to 1735 visiting notable observatories in Germany, Italy and France. He founded the Uppsala Astronomical Observatory in 1741, and in 1742 proposed the Centigrade temperature scale which was later renamed Celsius in his honour.

An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, moons, comets and galaxies – in either observational or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, solar astronomy, the origin or evolution of stars, or the formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole.

The Integrated Truss Structure (ITS) of the International Space Station (ISS) consists of a linear arranged sequence of connected trusses on which various unpressurized components are mounted such as logistics carriers, radiators, solar arrays, and other equipment. It supplies the ISS with a bus architecture. It is approximately 110 meters long and is made from aluminium and stainless steel.

Robert Lee Curbeam Jr. is a former NASA astronaut and captain in the United States Navy. He currently holds the record for the most spacewalks during a single spaceflight, accomplished during the STS-116 mission, when Curbeam completed four spacewalks.

A frisbee, also called a flying disc or simply a disc, is a gliding toy or sporting item that is generally made of injection-molded plastic and roughly 8 to 10 inches in diameter with a pronounced lip. It is used recreationally and competitively for throwing and catching, as in flying disc games. The shape of the disc is an airfoil in cross-section which allows it to fly by reducing the drag and increasing lift as it moves through the air, compared to a flat plate. Spinning the disc imparts a stabilizing gyroscopic force, allowing it to be both aimed with accuracy and thrown for distance.

The World Flying Disc Federation (WFDF) is the international governing body for flying disc (Frisbee) sports, with responsibility for sanctioning world championship events, establishing uniform rules, setting of standards for and recording of world records. WFDF is a federation of member associations which represent flying disc sports and their athletes in 100 countries. WFDF is an international federation recognized by the International Olympic Committee (IOC), a member of the Association of IOC Recognised International Sports Federations (ARISF), GAISF, and the International World Games Association (IWGA), and it is a registered not-for-profit 501(c)(3) corporation in the state of Colorado, U.S.

STS-128 was a NASA Space Shuttle mission to the International Space Station (ISS) that launched on August 28, 2009. Space Shuttle Discovery carried the Multi-Purpose Logistics Module Leonardo as its primary payload. Leonardo contained a collection of experiments for studying the physics and chemistry of microgravity. Three spacewalks were carried out during the mission, which removed and replaced a materials processing experiment outside ESA's Columbus module, and returned an empty ammonia tank assembly.

Umeå University is a public research university located in Umeå, in the mid-northern region of Sweden. The university was founded in 1965 and is the fifth oldest within Sweden's present borders.

The NASA Space Flight Medal is a decoration of the National Aeronautics and Space Administration. According to its statutes, it is awarded "for significant achievement or service during individual participation as a civilian or military astronaut, pilot, mission specialist, payload specialist, or other space flight participant in a space flight mission." In practice, the medal is bestowed upon any astronaut who flies aboard a United States space mission, and typically every subsequent flight is honored with an additional award.

H. M. The King's Medal, earlier known as the Court Medal, is a Swedish honour that may be bestowed upon Swedish and foreign citizens. The medal was created in 1814 and is awarded in different sizes in gold and silver with chain or ribbon. This medal is not awarded in classes but in sizes. The 12th size is the largest and is worn around the neck on a chain or ribbon. The 8th and 5th size are worn from the left breast suspended by a ribbon, after the Seraphim Medal.

The NASA Exceptional Service Medal is an award granted to U.S. government employees for significant sustained performance characterized by unusual initiative or creative ability that clearly demonstrates substantial improvement in engineering, aeronautics, space flight, administration, support, or space-related endeavors which contribute to NASA programs.
