Eve Torrence
Eve Alexandra Littig Torrence (born 1963) is an American mathematician, a professor emerita of mathematics at Randolph–Macon College, and a former president of mathematics society Pi Mu Epsilon. She is known for her award-winning writing and books in mathematics, for her mathematical origami art, and for her efforts debunking overly broad claims regarding the ubiquity of the golden ratio. Education, career, and service Torrence was an undergraduate at Tufts University. She completed her Ph.D. in 1991 at the University of Virginia; her dissertation, ''The Coordination of a Hexagonal-Barbilian Plane by a Quadratic Jordan Algebra'', was supervised by John Faulkner. She was Claire Booth Luce assistant professor at Trinity Washington University from 1991 to 1994, before joining the Randolph–Macon College faculty in 1994. She earned tenure there in 1999, and became a full professor in 2008. She retired in 2021, and was given the Bruce M. Unger Award by Randolph–Macon College ...

Professor Emerita
''Emeritus'' (; female: ''emerita'') is an adjective used to designate a retired chair, professor, pastor, bishop, pope, director, president, prime minister, rabbi, emperor, or other person who has been "permitted to retain as an honorary title the rank of the last office held". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished service awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title, e.g., "professor emeritus". The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In the description of deceased professors emeritus listed at U.S. universities, the title ''emeritus'' is replaced by indicating the years of their appointmentsThe Proto ...

Rhombus
In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length. The rhombus is often called a "diamond", after the diamonds suit in playing cards which resembles the projection of an octahedral diamond, or a lozenge, though the former sometimes refers specifically to a rhombus with a 60° angle (which some authors call a calisson after the French sweet – also see Polyiamond), and the latter sometimes refers specifically to a rhombus with a 45° angle. Every rhombus is simple (non-self-intersecting), and is a special case of a parallelogram and a kite. A rhombus with right angles is a square. Etymology The word "rhombus" comes from grc, ῥόμβος, rhombos, meaning something that spins, which derives from the verb , romanized: , meaning "to turn round and round." The word was used both by Eucl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Virginia Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Tufts University Alumni
Tufts University is a private research university on the border of Medford and Somerville, Massachusetts. It was founded in 1852 as Tufts College by Christian universalists who sought to provide a nonsectarian institution of higher learning. Tufts remained a small New England liberal arts college until the 1970s, when it transformed into a large research university offering several doctorates;Its corporate name is still "The Trustees of Tufts College" it is classified as a "Research I university", denoting the highest level of research activity. Tufts is a member of the Association of American Universities, a selective group of 64 leading research universities in North America. The university is known for its internationalism, study abroad programs, and promoting active citizenship and public service across all disciplines. Tufts offers over 90 undergraduate and 160 graduate programs across ten schools in the greater Boston area and Talloires, France.

Rhombic Dodecahedron
In geometry, the rhombic dodecahedron is a convex polyhedron with 12 congruent rhombic faces. It has 24 edges, and 14 vertices of 2 types. It is a Catalan solid, and the dual polyhedron of the cuboctahedron. Properties The rhombic dodecahedron is a zonohedron. Its polyhedral dual is the cuboctahedron. The long face-diagonal length is exactly times the short face-diagonal length; thus, the acute angles on each face measure arccos(), or approximately 70.53°. Being the dual of an Archimedean polyhedron, the rhombic dodecahedron is face-transitive, meaning the symmetry group of the solid acts transitively on its set of faces. In elementary terms, this means that for any two faces A and B, there is a rotation or reflection of the solid that leaves it occupying the same region of space while moving face A to face B. The rhombic dodecahedron can be viewed as the convex hull of the union of the vertices of a cube and an octahedron. The 6 vertices where 4 rhombi meet correspond t ...

Hyperbolic Paraboloid
In geometry, a paraboloid is a quadric surface that has exactly one axis of symmetry and no center of symmetry. The term "paraboloid" is derived from parabola, which refers to a conic section that has a similar property of symmetry. Every plane section of a paraboloid by a plane parallel to the axis of symmetry is a parabola. The paraboloid is hyperbolic if every other plane section is either a hyperbola, or two crossing lines (in the case of a section by a tangent plane). The paraboloid is elliptic if every other nonempty plane section is either an ellipse, or a single point (in the case of a section by a tangent plane). A paraboloid is either elliptic or hyperbolic. Equivalently, a paraboloid may be defined as a quadric surface that is not a cylinder, and has an implicit equation whose part of degree two may be factored over the complex numbers into two different linear factors. The paraboloid is hyperbolic if the factors are real; elliptic if the factors are complex conjugate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Randolph–Macon College
Randolph–Macon College is a private liberal arts college in Ashland, Virginia. Founded in 1830, the college has an enrollment of more than 1,500 students. It is the second-oldest Methodist-run college in the country, and the oldest in continuous operation. The college currently offers bachelor's degrees, though the institution has announced plans to provide a Master of Science in physician's assistant studies with the first cohort of students entering in 2021–2022. History Randolph–Macon was founded in 1830 by Methodists Rev. Hekeziah G. Leigh, Rev. John Early and Staten Islander Gabriel Poillon Disosway. It was originally located in Boydton, near the North Carolina border; but as the railroad link to Boydton was destroyed during the Civil War, the college's trustees decided to relocate the school to Ashland in 1868. The college takes its name from Virginia statesmen John Randolph of Roanoke and North Carolina statesman Nathaniel Macon. (The original site of Randolph ...
