Mary Gertrude Haseman
Mary Gertrude Haseman (March 6, 1889 – April 9, 1979) was an American mathematician known for her work in knot theory. Biography Mary Gertrude Haseman was born in or near the small town of Linton, Indiana, the seventh of nine children, to Elizabeth Christine (Schultze) and John Dieterich Haseman. Despite being raised on a farm, she and her siblings all pursued higher education; they all attended college, five had master's degrees, and five, including Mary, earned PhDs. Haseman attended Indiana University and graduated ''cum laude'' with a bachelor of arts degree in 1910. She taught mathematics at Vincennes University for the academic year 1910–11 before starting a doctoral program in mathematics at Bryn Mawr College in 1911. In 1915, while still working on her dissertation, she moved to Baltimore where she taught at the Roland Park Country School and took graduate classes from Frank Morley at Johns Hopkins University. She successfully defended her PhD thesis at Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linton, Indiana
Linton is a city in Stockton Township, Greene County, Indiana, United States. The population was 5,413 at the 2010 census. A coal mining city, it is located southeast of Terre Haute. The current mayor is John Wilkes. Linton is part of the Bloomington, Indiana, metropolitan area. History Linton was essentially founded around the entrepreneuring of John W. Wines, who first sold goods in the Linton area, briefly in 1831. Although he would later relocate to Fairplay, Indiana, he returned and opened a general store in Linton in 1837. He would later build a small horse mill as well as a tannery. The city itself was officially chartered and named in June 1850, laid out by Hannah E. Osborn and Isaac V. Coddington. In the late 19th century, small underground coal mines began to appear near and almost inside the city and the population expanded rapidly. At the turn of the 20th century, the population was larger than it is today. At one point in the 1920s, there were at least 35 drinkin ...

Johns Hopkins University
Johns Hopkins University (Johns Hopkins, Hopkins, or JHU) is a private university, private research university in Baltimore, Maryland. Founded in 1876, Johns Hopkins is the oldest research university in the United States and in the western hemisphere. It consistently ranks among the most prestigious universities in the United States and the world. The university was named for its first benefactor, the American entrepreneur and Quaker philanthropist Johns Hopkins. Hopkins' $7 million bequest to establish the university was the largest Philanthropy, philanthropic gift in U.S. history up to that time. Daniel Coit Gilman, who was inaugurated as :Presidents of Johns Hopkins University, Johns Hopkins's first president on February 22, 1876, led the university to revolutionize higher education in the U.S. by integrating teaching and research. In 1900, Johns Hopkins became a founding member of the American Association of Universities. The university has led all Higher education in the U ...

Crossing Number (knot Theory)
In the mathematical area of knot theory, the crossing number of a knot is the smallest number of crossings of any diagram of the knot. It is a knot invariant. Examples By way of example, the unknot has crossing number zero, the trefoil knot three and the figure-eight knot four. There are no other knots with a crossing number this low, and just two knots have crossing number five, but the number of knots with a particular crossing number increases rapidly as the crossing number increases. Tabulation Tables of prime knots are traditionally indexed by crossing number, with a subscript to indicate which particular knot out of those with this many crossings is meant (this sub-ordering is not based on anything in particular, except that torus knots then twist knots are listed first). The listing goes 31 (the trefoil knot), 41 (the figure-eight knot), 51, 52, 61, etc. This order has not changed significantly since P. G. Tait published a tabulation of knots in 1877.

Alternating Knot
In knot theory, a knot or link diagram is alternating if the crossings alternate under, over, under, over, as one travels along each component of the link. A link is alternating if it has an alternating diagram. Many of the knots with crossing number less than 10 are alternating. This fact and useful properties of alternating knots, such as the Tait conjectures, was what enabled early knot tabulators, such as Tait, to construct tables with relatively few mistakes or omissions. The simplest non-alternating prime knots have 8 crossings (and there are three such: 819, 820, 821). It is conjectured that as the crossing number increases, the percentage of knots that are alternating goes to 0 exponentially quickly. Alternating links end up having an important role in knot theory and 3-manifold theory, due to their complements having useful and interesting geometric and topological properties. This led Ralph Fox to ask, "What is an alternating knot?" By this he was asking what non-diag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peter Tait (physicist)
Peter Guthrie Tait FRSE (28 April 1831 – 4 July 1901) was a Scottish mathematical physicist and early pioneer in thermodynamics. He is best known for the mathematical physics textbook '' Treatise on Natural Philosophy'', which he co-wrote with Lord Kelvin, and his early investigations into knot theory. His work on knot theory contributed to the eventual formation of topology as a mathematical discipline. His name is known in graph theory mainly for Tait's conjecture. He is also one of the namesakes of the Tait–Kneser theorem on osculating circles. Early life Tait was born in Dalkeith on 28 April 1831 the only son of Mary Ronaldson and John Tait, secretary to the 5th Duke of Buccleuch. He was educated at Dalkeith Grammar School then Edinburgh Academy. He studied Mathematics and Physics at the University of Edinburgh, and then went to Peterhouse, Cambridge, graduating as senior wrangler and first Smith's prizeman in 1852. As a fellow and lecturer of his college he remain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiral Knot
In the mathematical field of knot theory, a chiral knot is a knot that is ''not'' equivalent to its mirror image (when identical while reversed). An oriented knot that is equivalent to its mirror image is an amphicheiral knot, also called an achiral knot. The chirality of a knot is a knot invariant. A knot's chirality can be further classified depending on whether or not it is invertible. There are only five knot symmetry types, indicated by chirality and invertibility: fully chiral, invertible, positively amphicheiral noninvertible, negatively amphicheiral noninvertible, and fully amphicheiral invertible.. Background The possible chirality of certain knots was suspected since 1847 when Johann Listing asserted that the trefoil was chiral, and this was proven by Max Dehn in 1914. P. G. Tait found all amphicheiral knots up to 10 crossings and conjectured that all amphicheiral knots had even crossing number. Mary Gertrude Haseman found all 12-crossing and many 14-crossing amphicheir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
