Ambigrams
An ambigram is a calligraphic design that has several interpretations as written. The term was coined by Douglas Hofstadter in 1983. Most often, ambigrams appear as visually symmetrical words. When flipped, they remain unchanged, or they mutate to reveal another meaning. "Half-turn" ambigrams undergo a point reflection (180° rotational symmetry) and can be read upside down, mirror ambigrams have an axial symmetry and can be read through a reflective surface (like a mirror or a mirroring lake), and many other types of ambigrams exist. Ambigrams are found in different languages, various alphabets and the notion often extends to numbers and other symbols. It is a recent interdisciplinary concept, combining art, literature, mathematics, cognition, and optical illusions. Drawing symmetrical words constitutes also a recreational activity for amateurs. Numerous ambigram logos are famous, and ambigram tattoos have become increasingly popular. There are methods to design an ambigram, ...

Lennart Green
Sven Lennart Green (born 25 December 1941) is a Swedish world champion close-up/card magician, a title which he won in 1991 at the FISM convention in Lausanne, Switzerland. He is known for his seemingly chaotic routines which, in spite of first appearances, display great skill. His original techniques and presentation style form an unorthodox and innovative contribution to sleight of hand magic. Biography Green began practicing magic at the age of 18. Green competed at the 1988 FISM convention in The Hague, Netherlands, and was erroneously disqualified because the judges believed he had used stooges in his act to shuffle the cards. In 1991, he performed the same act but insisted that the judges themselves shuffle the cards to prove that he used no stooges. The judges then awarded him first place. Green has appeared on the fourth World's Greatest Magic television special. He lives in Gothenburg Gothenburg (; abbreviated Gbg; sv, Göteborg ) is the second-largest city ...

Persi Diaconis
Persi Warren Diaconis (; born January 31, 1945) is an American mathematician of Greek descent and former professional magician. He is the Mary V. Sunseri Professor of Statistics and Mathematics at Stanford University. He is particularly known for tackling mathematical problems involving randomness and randomization, such as coin flipping and shuffling playing cards. Biography Diaconis left home at 14 to travel with sleight-of-hand legend Dai Vernon, and dropped out of high school, returning to school at age 24 to learn math, motivated to read William Feller's famous two-volume treatise on probability theory, ''An Introduction to Probability Theory and Its Applications''. He attended the City College of New York for his undergraduate work, graduating in 1971, and then obtained a Ph.D. in Mathematical Statistics from Harvard University in 1974), learned to read Feller, and became a mathematical probabilist.Jeffrey R.

Donald Coxeter
Harold Scott MacDonald "Donald" Coxeter, (9 February 1907 – 31 March 2003) was a British and later also Canadian geometer. He is regarded as one of the greatest geometers of the 20th century. Biography Coxeter was born in Kensington to Harold Samuel Coxeter and Lucy (). His father had taken over the family business of Coxeter & Son, manufacturers of surgical instruments and compressed gases (including a mechanism for anaesthetising surgical patients with nitrous oxide), but was able to retire early and focus on sculpting and baritone singing; Lucy Coxeter was a portrait and landscape painter who had attended the Royal Academy of Arts. A maternal cousin was the architect Sir Giles Gilbert Scott. In his youth, Coxeter composed music and was an accomplished pianist at the age of 10. Roberts, Siobhan, ''King of Infinite Space: Donald Coxeter, The Man Who Saved Geometry'', Walker & Company, 2006, He felt that mathematics and music were intimately related, outlining his i ...

Arthur T
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ...

Jerry Andrus
Jerry Andrus (January 28, 1918 – August 26, 2007) was an American magician and writer known internationally for his original close-up, sleight of hand tricks and optical illusions, such as the famous "Linking Pins". Early life Andrus was born January 28, 1918, in Sheridan, Wyoming. At the age of 10, he moved to Albany, Oregon, where he lived until his death in 2007. At 12, Andrus became interested in the art of illusion when he saw a performance of a reformed " spiritual medium". He joined the International Society of Junior Magicians when he was 16 and soon became known as a "magician’s magician". Career Magic A self-taught magician, Andrus preferred to develop his own style rather than learn the craft as traditionally handed down from other magicians, eventually becoming world renowned as one of the "best and most-influential 'close-up magic' performers ever." He was known to many accomplished contemporary magicians, such as Lance Burton, Doug Henning, and Penn & Tell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ingrid Daubechies
Baroness Ingrid Daubechies ( ; ; born 17 August 1954) is a Belgian physicist and mathematician. She is best known for her work with wavelets in image compression. Daubechies is recognized for her study of the mathematical methods that enhance image-compression technology. She is a member of the National Academy of Engineering, the National Academy of Sciences and the American Academy of Arts and Sciences. She is a 1992 MacArthur Fellow. She also served on the Mathematical Sciences jury for the Infosys Prize from 2011 to 2013.
