Gerard K. O'Neill
Gerard Kitchen O'Neill (February 6, 1927 – April 27, 1992) was an American physicist and space activist. As a faculty member of Princeton University, he invented a device called the particle storage ring for high-energy physics experiments. Later, he invented a magnetic launcher called the mass driver. In the 1970s, he developed a plan to build human settlements in outer space, including a space habitat design known as the O'Neill cylinder. He founded the Space Studies Institute, an organization devoted to funding research into space manufacturing and colonization. O'Neill began researching high-energy particle physics at Princeton in 1954, after he received his doctorate from Cornell University. Two years later, he published his theory for a particle storage ring. This invention allowed particle accelerators at much higher energies than had previously been possible. In 1965 at Stanford University, he performed the first colliding beam physics experiment. While teaching ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brooklyn
Brooklyn is a Boroughs of New York City, borough of New York City located at the westernmost end of Long Island in the New York (state), State of New York. Formerly an independent city, the borough is coextensive with Kings County, one of twelve original counties established under English rule in 1683 in what was then the Province of New York. As of the 2020 United States census, the population stood at 2,736,074, making it the most populous of the five boroughs of New York City, and the most populous Administrative divisions of New York (state)#County, county in the state.Table 2: Population, Land Area, and Population Density by County, New York State - 2020 New York State Department of Health.

Particle Physics
Particle physics or high-energy physics is the study of Elementary particle, fundamental particles and fundamental interaction, forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons, while the study of combinations of protons and neutrons is called nuclear physics. The fundamental particles in the universe are classified in the Standard Model as fermions (matter particles) and bosons (force-carrying particles). There are three Generation (particle physics), generations of fermions, although ordinary matter is made only from the first fermion generation. The first generation consists of Up quark, 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. Quark, Quarks cannot exist on their own but form hadrons. Hadrons that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newburgh Free Academy
Newburgh Free Academy (NFA) is the public high school educating all students in grades 9– 12 in the Newburgh Enlarged City School District, which serves the city of Newburgh, New York, most of each of the towns of Newburgh and New Windsor, Text list/ref> and portions of the towns of Cornwall and Walkill. In addition to Newburgh, the enlarged city school district includes the following census-designated places: Balmville, Gardnertown, and Vails Gate, as well as most of the New Windsor CDP and portions of the Orange Lake CDP. It traces its history back over two centuries, to the years prior to mandatory public education. History Early school The school traces its history back to the early days of the United States. The Rev. George H. Spierin proposed to open an "Academy" in Newburgh. Work began in 1796 under the direction of the trustees of the glebe. (A glebe was land originally set aside in the early 18th century for a pastor and his church. The glebe for the New ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speculator, New York
Speculator is a village in Hamilton County, New York, United States. The population was 406 at the 2020 census. The Speculator Mountain rises just south of the village. Speculator is the only incorporated village within Hamilton County and is within the town of Lake Pleasant. The village includes the northeastern end of a lake, also called Lake Pleasant. The local inhabitants sometimes refer to the village as the "Four Corners", referring to the intersection of NYS Route 8 and NYS Route 30 in the middle of the business district. Speculator is within the Adirondack Park. History Native Americans Archeological evidence of Native Americans has been found in arrowheads and spearheads near the shores of Lake Pleasant. Many historians believe Speculator was the hunting and fishing grounds of both Mohawk and Algonquin tribes. These Native Americans would only travel to the Adirondack Mountains to hunt during the warm months, while their villages were located in the Mohawk ...

Leukemia
Leukemia ( also spelled leukaemia; pronounced ) is a group of blood cancers that usually begin in the bone marrow and produce high numbers of abnormal blood cells. These blood cells are not fully developed and are called ''blasts'' or '' leukemia cells''. Symptoms may include bleeding and bruising, bone pain, fatigue, fever, and an increased risk of infections. These symptoms occur due to a lack of normal blood cells. Diagnosis is typically made by blood tests or bone marrow biopsy. The exact cause of leukemia is unknown. A combination of genetic factors and environmental (non-inherited) factors are believed to play a role. Risk factors include smoking, ionizing radiation, petrochemicals (such as benzene), prior chemotherapy, and Down syndrome. People with a family history of leukemia are also at higher risk. There are four main types of leukemia—acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and chronic myelo ...

Human Colonies In Space
Humans (''Homo sapiens'') or modern humans are the most common and widespread species of primate, and the last surviving species of the genus ''Homo''. They are great apes characterized by their hairlessness, bipedalism, and high intelligence. Humans have large brains, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations. Humans are highly social, with individual humans tending to belong to a multi-layered network of distinct social groups — from families and peer groups to corporations and political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and traditions (collectively termed institutions), each of which bolsters human society. Humans are also highly curious: the desire to understand and influence phenomena has motivated humanity's development of s ...
