The wolf, also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo, though gray wolves, as popularly understood, only comprise naturally-occurring wild subspecies. The wolf is the largest extant member of the family Canidae, and is further distinguished from other Canis species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller Canis species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The wolf's fur is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white.
Gwydion fab Dôn is a magician, hero and trickster of Welsh mythology, appearing most prominently in the Fourth Branch of the Mabinogi, which focuses largely on his relationship with his young nephew, Lleu Llaw Gyffes. He also appears prominently in the Welsh Triads, the Book of Taliesin and the Stanzas of the Graves.
In Welsh mythology, Math fab Mathonwy, also called Math ap Mathonwy was a king of Gwynedd who needed to rest his feet in the lap of a virgin unless he was at war, or he would die. The story of Math is the fourth of the Four Branches of the Mabinogi.
Arianrhod is a figure in Welsh mythology who plays her most important role in the Fourth Branch of the Mabinogi. She is the daughter of Dôn and the sister of Gwydion and Gilfaethwy; the Welsh Triads give her father as Beli Mawr. In the Mabinogi her uncle Math ap Mathonwy is the King of Gwynedd, and during the course of the story she gives birth to two sons, Dylan ail Don and Lleu Llaw Gyffes, through magical means.
Lleu Llaw Gyffes is a hero of Welsh mythology. He appears most prominently in the Fourth Branch of the Mabinogi, the tale of Math fab Mathonwy, which tells the tale of his birth, his marriage, his death, his resurrection and his accession to the throne of Gwynedd. He is a warrior and magician, invariably associated with his uncle Gwydion.
Jacques Tits was a Belgian-born French mathematician who worked on group theory and incidence geometry. He introduced Tits buildings, the Tits alternative, the Tits group, and the Tits metric.
In number theory, cousin primes are prime numbers that differ by four. Compare this with twin primes, pairs of prime numbers that differ by two, and sexy primes, pairs of prime numbers that differ by six.
Peter David Lax is a Hungarian-born American mathematician and Abel Prize laureate working in the areas of pure and applied mathematics.
Lars Valter Hörmander was a Swedish mathematician who has been called "the foremost contributor to the modern theory of linear partial differential equations". Hörmander was awarded the Fields Medal in 1962 and the Wolf Prize in 1988. In 2006 he was awarded the Steele Prize for Mathematical Exposition for his four-volume textbook Analysis of Linear Partial Differential Operators, which is considered a foundational work on the subject.
Paul Erdős was a Hungarian mathematician. He was one of the most prolific mathematicians and producers of mathematical conjectures of the 20th century. Erdős pursued and proposed problems in discrete mathematics, graph theory, number theory, mathematical analysis, approximation theory, set theory, and probability theory. Much of his work centered around discrete mathematics, cracking many previously unsolved problems in the field. He championed and contributed to Ramsey theory, which studies the conditions in which order necessarily appears. Overall, his work leaned towards solving previously open problems, rather than developing or exploring new areas of mathematics.
Doron Zeilberger is an Israeli mathematician, known for his work in combinatorics.
In number theory, Brun's theorem states that the sum of the reciprocals of the twin primes converges to a finite value known as Brun's constant, usually denoted by B2. Brun's theorem was proved by Viggo Brun in 1919, and it has historical importance in the introduction of sieve methods.
Three Little Pigs is an animated short film released on May 25, 1933, by United Artists, produced by Walt Disney and directed by Burt Gillett. Based on the fable of the same name, the Silly Symphony won the 1934 Academy Award for Best Animated Short Film of 1933. The short cost $22,000 and grossed $250,000.
"The Wolf and the Seven Young Goats" is a fairy tale collected by the Brothers Grimm and published in Grimm's Fairy Tales. It is of Aarne-Thompson type 123 "The Wolf and the Kids".
Three Little Wolves is a Silly Symphony cartoon. Released on April 18, 1936, and directed by Dave Hand. It was the third Silly Symphony cartoon starring the Three Little Pigs. It is loosely based on The Boy Who Cried Wolf. It introduces the Big Bad Wolf's sons, the Three Little Wolves, all of them just as eager for a taste of the pigs as their father.
John Lyon Burnside III was an American inventor and gay rights activist, known for inventing the teleidoscope, darkfield kaleidoscope, and the Symmetricon. Because he rediscovered the math behind kaleidoscope optics, makers of optically correct kaleidoscopes sold in the United States paid him royalties for decades. Burnside was the life partner of Harry Hay from 1962 until Hay's death in 2002. Burnside was living in San Francisco, at the time of his death on September 14, 2008, from complications of brain cancer.
In Welsh Mythology, Hyddwn appears in the fourth of the Four Branches of the Mabinogi and is one of the three sons of Gwydion and Gilfaethwy. As punishment for the rape of Goewin, Math banished his nephews, turning them into a breeding pair of deer for a year, then pigs, and finally wolves. They had three children over the three years: Hyddwn, Hychddwn, and Bleiddwn. Hyddwn is the offspring of the deer pairing. Math took him and transformed him into a human being, baptising him Hyddwn ("Stag-man").
Unstable Fables is a trilogy of computer-animated films produced by The Jim Henson Company in association with Flame Ventures, Prana Studios, and The Weinstein Company. The direct-to-DVD feature-length films were distributed by Genius Products.
Math fab Mathonwy, "Math, the son of Mathonwy" is a legendary tale from medieval Welsh literature and the final of the four branches of the Mabinogi. It tells of a vicious war between the north and the south, of the birth of Lleu Llaw Gyffes and Dylan ail Don, of the tyngedau of Arianrhod, and of the creation of Blodeuwedd, a woman made of flowers. The chief characters of the tale are Math, king of Gwynedd, his nephew Gwydion, a magician, warrior and trickster, and Gwydion's own nephew, Lleu, cursed by his mother Arianrhod.
The White Wolf is a French-language fairy tale collected from Wallonia by authors Auguste Gittée and Jules Lemoine. It is related to the international cycle of the Animal as Bridegroom or The Search for the Lost Husband, wherein a human princess marries a prince under an animal curse, loses him and has to search for him.
