James McMahon (mathematician)
James McMahon (April 22, 1856 – June 1, 1922) was an Irish mathematician whose career was spent at Cornell University in Ithaca, New York. He was a committed educator, and an early proponent of professionalization in the teaching of advanced mathematics in America. A professor and Chairman of the Mathematics Department in Cornell University, Cornell University's College of Arts & Sciences, McMahon was one of the earliest members of the American Mathematical Society (as the predecessor New York Mathematical Society) in 1891. For seven years he served as associate editor of the ''Annals of Mathematics''. He was also the American Association for the Advancement of Science, American Association for the Advancement of Science's Secretary (1897), Section A (Mathematics and Astronomy); General Secretary (1898), and Vice-President (1901). McMahon was also featured in the publication, ''American Men (and Women) of Science''. Early life Professor McMahon was born in County Armagh, Irela ...

19th-century Irish Mathematicians
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It was characterized by vast social upheaval. Slavery was Abolitionism, abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems an ...

Goniometry
A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry derives from two Greek words, γωνία (''gōnía'') 'angle' and μέτρον (''métron'') ' measure'. The protractor is a commonly used type in the fields of mechanics, engineering, and geometry. The first known description of a goniometer, based on the astrolabe, was by Gemma Frisius in 1538. Protractor A protractor is a measuring instrument, typically made of transparent plastic, for measuring angles. Some protractors are simple half-discs or full circles. More advanced protractors, such as the bevel protractor, have one or two swinging arms, which can be used to help measure the angle. Most protractors measure angles in degrees (°). Radian-scale protractors measure angles in radians. Most protractors are divided into 180 equal parts. Some precision protractors further divide degrees into arcminutes. A protractor divided i ...

The Irving Literary Society (Cornell University)
The Irving Literary Society (also known as the Irving Literary Association or simply The Irving) was a College literary societies, literary society at Cornell University active from 1868 to 1887. The U.S. Department of Education, U.S. Bureau of Education described it as a "purely literary society" following the "traditions of the old literary societies of Eastern universities." During the period when the Cornell literary societies flourished, the Irving and its peers produced literature at a rate higher than the campus average for the next generation, leading commentators at the turn of the 20th century to question whether academic standards had fallen since the university's founding. Named after the American writer Washington Irving, the Irving Literary Society was founded on October 20, 1868, shortly after Cornell opened. Past members who went on to prominent careers included Judge Morris Lyon Buchwalter, Senator Joseph Benson Foraker, and the journalists John Andrew Rea and Fr ...

Phi Kappa Psi
Phi Kappa Psi (), commonly known as Phi Psi, is an American collegiate social fraternity that was founded at Jefferson College in Canonsburg, Pennsylvania in 1852. The fraternity has over ninety chapters at accredited four-year colleges and universities throughout the United States. More than 179,000 men have been initiated into Phi Kappa Psi since its founding. Phi Kappa Psi and Phi Gamma Delta, both founded at the same college, form the Jefferson Duo. History In the winter of 1850, a typhoid fever epidemic hit Jefferson College in Canonsburg, Pennsylvania. Many students left school. Among those who remained were William Henry Letterman and Charles Page Thomas Moore. They chose to care for their classmates who were stricken with the contagious disease, and a strong bond was formed. The following school year, Letterman and Moore decided to found a fraternity based on "the great joy of serving others" that they experienced during the epidemic. Letterman and Moore founded ...
