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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Particle Accelerator
A particle accelerator is a machine that uses electromagnetic fields to propel charged particles to very high speeds and energies, and to contain them in well-defined beams. Large accelerators are used for fundamental research in particle physics. The largest accelerator currently active is the Large Hadron Collider (LHC) near Geneva, Switzerland, operated by the CERN. It is a collider accelerator, which can accelerate two beams of protons to an energy of 6.5 TeV and cause them to collide head-on, creating center-of-mass energies of 13 TeV. Other powerful accelerators are, RHIC at Brookhaven National Laboratory in New York and, formerly, the Tevatron at Fermilab, Batavia, Illinois. Accelerators are also used as synchrotron light sources for the study of condensed matter physics. Smaller particle accelerators are used in a wide variety of applications, including particle therapy for oncological purposes, radioisotope production for medical diagnostics, ion ...

Newburgh, New York
Newburgh is a city in the U.S. state of New York, within Orange County. With a population of 28,856 as of the 2020 census, it is a principal city of the Poughkeepsie–Newburgh–Middletown metropolitan area. Located north of New York City, and south of Albany on the Hudson River within the Hudson Valley Area, the city of Newburgh is located near Stewart International Airport, one of the primary airports for Downstate New York. The Newburgh area was first settled in the early 18th century by the Germans and British. During the American Revolution, Newburgh served as the headquarters of the Continental Army. Prior to its chartering in 1865, the city of Newburgh was part of the town of Newburgh; the town now borders the city to the north and west. East of the city is the Hudson River; the city of Beacon is across the river and it is connected to Newburgh via the Newburgh–Beacon Bridge. The entire southern boundary of the city is with the town of New Windsor. Most of this ... [...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, the towns of Newburgh and New Windsor, and portions of the towns of Marlboro, New York, Cornwall, New York and various others. 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 Newburgh area was issued in 1719.) A portion of the first Academy was occupied in 1797. The building was by 40 feet (18.5 × 12.3m), two stories high, built of wood, and lined with brick. It was located on Liberty Street and co ...

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 and ...

Leukemia
Leukemia ( also spelled leukaemia and pronounced ) is a group of blood cancers that usually begin in the bone marrow and result in 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 myeloi ...

Human Colonies In Space
Humans (''Homo sapiens'') are the most abundant and widespread species of primate, characterized by bipedalism and exceptional cognitive skills due to a large and complex brain. This has enabled the development of advanced tools, culture, and language. Humans are highly social and tend to live in complex social structures composed of many cooperating and competing groups, from families and kinship networks to political states. Social interactions between humans have established a wide variety of values, social norms, and rituals, which bolster human society. Its intelligence and its desire to understand and influence the environment and to explain and manipulate phenomena have motivated humanity's development of science, philosophy, mythology, religion, and other fields of study. Although some scientists equate the term ''humans'' with all members of the genus ''Homo'', in common usage, it generally refers to ''Homo sapiens'', the only extant member.
