Columbia University Tunnels
Columbia University in New York City has an extensive tunnel system underneath its Morningside Heights campus connecting many of its buildings, used by the university as conduits for steam, electricity, telecommunications, and other infrastructure. Throughout their history, the tunnels have also been used for other purposes, mostly centering around transportation. During the first half of the 20th century, they were used by students to avoid aboveground traffic. When the university housed the Manhattan Project, they were allegedly used to move radioactive material between buildings. During the Columbia University protests of 1968, students used the tunnels to facilitate their occupation of buildings on campus. Throughout their history, the tunnels have been thoroughly explored by generations of students, and have been the subject of numerous campus legends. Though sections have been cordoned off by the university since the 1960s, either in response to the 1968 protests or rampant ...

Columbia University
Columbia University (also known as Columbia, and officially as Columbia University in the City of New York) is a private research university in New York City. Established in 1754 as King's College on the grounds of Trinity Church in Manhattan, Columbia is the oldest institution of higher education in New York and the fifth-oldest institution of higher learning in the United States. It is one of nine colonial colleges founded prior to the Declaration of Independence. It is a member of the Ivy League. Columbia is ranked among the top universities in the world. Columbia was established by royal charter under George II of Great Britain. It was renamed Columbia College in 1784 following the American Revolution, and in 1787 was placed under a private board of trustees headed by former students Alexander Hamilton and John Jay. In 1896, the campus was moved to its current location in Morningside Heights and renamed Columbia University. Columbia scientists and scholars have ...

Shooting Range
A shooting range, firing range, gun range or shooting ground is a specialized facility, sports venue, venue or playing field, field designed specifically for firearm usage qualifications, training, practice or shooting sport, competitions. Some shooting ranges are operated by military or law enforcement agencies, though the majority of ranges are privately owned by civilians and sporting clubs and cater mostly to recreational shooters. Each facility is typically overseen by one or more supervisory personnel, variously called a ''range master'' or "Range Safety Officer" (RSO) in the United States, or a ''range conducting officer'' (RCO) in the United Kingdom. Supervisory personnel are responsible for ensuring that all weapon safety rules and relevant gun law, government regulations are followed at all times. Shooting ranges can be indoor or outdoor, and may be restricted to certain types of firearm that can be used such as handguns or long guns, or they can specialize in cert ...

Uranium-238
Uranium-238 (238U or U-238) is the most common isotope of uranium found in nature, with a relative abundance of 99%. Unlike uranium-235, it is non-fissile, which means it cannot sustain a chain reaction in a thermal-neutron reactor. However, it is fissionable by fast neutrons, and is ''fertile'', meaning it can be transmuted to fissile plutonium-239. 238U cannot support a chain reaction because inelastic scattering reduces neutron energy below the range where fast fission of one or more next-generation nuclei is probable. Doppler broadening of 238U's neutron absorption resonances, increasing absorption as fuel temperature increases, is also an essential negative feedback mechanism for reactor control. Around 99.284% of natural uranium's mass is uranium-238, which has a half-life of 1.41 seconds (4.468 years, or 4.468 billion years). Due to its natural abundance and half-life relative to other radioactive elements, 238U produces ~40% of the radioactive heat produced within th ...

Ken Hechtman
Ken Hechtman (born December 16, 1967) is a freelance journalist and convicted drug dealer from Canada who achieved brief international prominence in late 2001 when Afghanistan's Taliban government charged him with being a United States spy while he researched a story for the ''Montreal Mirror''. Afghanistan tried, acquitted, and released him after a short time in jail. He attended Columbia University, and was expelled his freshman year for stealing uranium-238 from the university's former Manhattan Project laboratories. He married fellow Montrealer and journalist Wendy Hechtman on September 12, 2015. They moved to Nebraska in February 2016. Criminal charges According to police investigators, Hechtman and his wife Wendy invented a pastel-colored version of carfentanil, an opioid that can be up to 10,000 times more powerful than morphine and that can kill a human with only a few grains touching human skin. Hechtman and Wendy allegedly "developed a sophisticated marketing system wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phi Beta Kappa
The Phi Beta Kappa Society () is the oldest academic honor society in the United States, and the most prestigious, due in part to its long history and academic selectivity. Phi Beta Kappa aims to promote and advocate excellence in the liberal arts and sciences, and to induct the most outstanding students of arts and sciences at only select American colleges and universities. It was founded at the College of William and Mary on December 5, 1776, as the first collegiate Greek-letter fraternity and was among the earliest collegiate fraternal societies. Since its inception, 17 U.S. Presidents, 40 U.S. Supreme Court Justices, and 136 Nobel Laureates have been inducted members. Phi Beta Kappa () stands for ('), which means "Wisdom it. love of knowledgeis the guide it. helmsmanof life". Membership Phi Beta Kappa has chapters in only about 10% of American higher learning institutions, and only about 10% of these schools' Arts and Sciences graduates are invited to join the society. ...

Barnard Greek Games
The Barnard Greek Games are a tradition at Barnard College, a women's college affiliated with Columbia University in New York City, New York. They were first held in 1903, when the Class of 1905 challenged the Class of 1906 to an informal athletic contest, and would be held continuously until the Columbia University protests of 1968, when the games stopped entirely. They would be revived several times after 1968, first in 1989 as part of the college's centennial celebrations. Though they began as a competition between the freshman and sophomore classes, the games would eventually expand to include the entire student body. The games seek to emulate sports in ancient Greece with costumes, sets, and ceremonies. Traditional events have included the recitation of Greek poetry, dance, hoop rolling, chariot racing, and a torch race. However, the games have also included events such as lawn tennis, field hockey, and capture the flag Capture the flag (CTF) is a traditional outdoor spor ...

Hartley Hall
Hartley Hall was the first official residence hall (or dormitory) constructed on the campus of Columbia University's Morningside Heights campus, and currently houses undergraduate students from Columbia College as well as the Fu Foundation School of Engineering and Applied Science. The building is named for Columbia alumnus Marcellus Hartley Dodge, who donated $300,000 for its construction shortly after his graduation. The building was meant as a memorial to his grandfather, Marcellus Hartley, the owner of Remington Arms, who died during Dodge's sophomore year and who bequeathed him the family fortune. Dodge hoped to create “the commencement of a true dormitory system" at Columbia. Construction began on Hartley Hall in 1904 and it opened in tandem with Livingston Hall in 1905, welcoming students with its lobby of marble and oak. 200 students were housed in corridor-style rooms of various sizes. Lounges provided opportunities for social events such as teas with professors, alth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
