The Knot Atlas is a website, an encyclopedia rather than atlas, dedicated to knot theory. It and its predecessor were created by mathematician Dror Bar-Natan, who maintains the current site with Scott Morrison. According to Schiller, the site contains, "beautiful illustrations and detailed information about knots," as does KnotPlot.com. [1] According to the site itself, it is a knot atlas (collection of maps), theory database, knowledge base, and "a home for some computer programs". [2]
In knot theory, a figure-eight knot is the unique knot with a crossing number of four. This makes it the knot with the third-smallest possible crossing number, after the unknot and the trefoil knot. The figure-eight knot is a prime knot.

John Carlos Baez is an American mathematical physicist and a professor of mathematics at the University of California, Riverside (UCR) in Riverside, California. He has worked on spin foams in loop quantum gravity, applications of higher categories to physics, and applied category theory. Additionally, Baez is known on the World Wide Web as the author of the crackpot index.
In mathematics, a knot is an embedding of the circle into three-dimensional Euclidean space, R3. Often two knots are considered equivalent if they are ambient isotopic, that is, if there exists a continuous deformation of R3 which takes one knot to the other.
In knot theory, a branch of mathematics, the trefoil knot is the simplest example of a nontrivial knot. The trefoil can be obtained by joining the two loose ends of a common overhand knot, resulting in a knotted loop. As the simplest knot, the trefoil is fundamental to the study of mathematical knot theory.
A rat king is a collection of rats or mice whose tails are intertwined and bound together in some way. This could be a result of an entangling material like hair, a sticky substance such as sap or gum, or the tails being tied together.
The Schiller Institute is a German-based political and economic think tank founded in 1984 by Helga Zepp-LaRouche, with stated members in 50 countries. It is among the principal front organizations of the LaRouche movement. The institute's stated aim is to apply the ideas of the poet and philosopher Friedrich Schiller to what it calls the "contemporary world crisis." The Independent describes it as "an extremist political think-tank linked to a right-wing conspiracy theorist, Lyndon LaRouche." According to The Times, its aim is "to propagate [LaRouche's] increasingly wild anti-Semitic conspiracy theories."
A censure is an expression of strong disapproval or harsh criticism. In parliamentary procedure, it is a debatable main motion that could be adopted by a majority vote. Among the forms that it can take are a stern rebuke by a legislature, a spiritual penalty imposed by a church, or a negative judgment pronounced on a theological proposition. It is usually non-binding, unlike a motion of no confidence.

Scott John Morrison is an Australian former politician who served as the 30th prime minister of Australia from 2018 to 2022. He held office as leader of the Liberal Party of Australia and was the member of parliament (MP) for the New South Wales division of Cook from 2007 until 2024.
Dinosaur Ridge is a segment of the Dakota Hogback in the Morrison Fossil Area National Natural Landmark located in Jefferson County, Colorado, near the town of Morrison and just west of Denver.
Solomon's knot is a traditional decorative motif used since ancient times, and found in many cultures. Despite the name, it is classified as a link, and is not a true knot according to the definitions of mathematical knot theory.
The Journal of Knot Theory and Its Ramifications was established in 1992 by Louis Kauffman and was the first journal purely devoted to knot theory. It is an interdisciplinary journal covering developments in knot theory, with emphasis on creating connections between with other branches of mathematics and the natural sciences. The journal is published by World Scientific.
The Sierra Prieta is a 14 miles (23 km) long mountain range in central-northwest Arizona. The range is the mountainous region west of Prescott, with prominent Thumb Butte, 6,514 feet (1,985 m), a volcanic plug, on the city's west perimeter.
The vortex theory of the atom was a 19th-century attempt by William Thomson to explain why the atoms recently discovered by chemists came in only relatively few varieties but in very great numbers of each kind. Based on the idea of stable, knotted vortices in the ether or aether, it contributed an important mathematical legacy.
Scott William Atlas is an American radiologist, political commentator, and health care policy advisor. He is the Robert Wesson Senior Fellow in health care policy at the Hoover Institution, a conservative think tank located at Stanford University. During the United States presidential campaigns of 2008, 2012, and 2016, Atlas was a Senior Advisor for Health Care to several presidential candidates. From 1998 to 2012 he was a professor and chief of neuroradiology at Stanford University Medical Center.
The magical Girdle of Aphrodite or Venus, variously interpreted as girdle, belt, breast-band, and otherwise, is one of the erotic accessories of Aphrodite, the Greek goddess of love and beauty. According to Homer, the girdle was imbued with the power to inspire the passion of desire in mortals and immortals alike. Hera, in her role as the goddess of marriage, sometimes borrowed it from Aphrodite to mitigate lovers' quarrels, to instigate the bridal contests of suitors, and on at least one occasion to manipulate her husband Zeus.
