Ahmes
Ahmes ( egy, jꜥḥ-ms “, a common Egyptian name also transliterated Ahmose) was an ancient Egyptian scribe who lived towards the end of the Fifteenth Dynasty (and of the Second Intermediate Period) and the beginning of the Eighteenth Dynasty (and of the New Kingdom). He transcribed the Rhind Mathematical Papyrus, a work of ancient Egyptian mathematics that dates to approximately 1550 BC; he is the earliest contributor to mathematics whose name is known. He's also the first mathematician to use fractions. Ahmes claimed not to be the writer of the work but rather just the scribe. He claimed the material came from an even older document from around 2000 B.C. See also * List of ancient Egyptian scribes This is a list of Egyptian scribes, almost exclusively from the ancient Egyptian periods.

Gerolamo Cardano
Gerolamo Cardano (; also Girolamo or Geronimo; french: link=no, Jérôme Cardan; la, Hieronymus Cardanus; 24 September 1501– 21 September 1576) was an Italian polymath, whose interests and proficiencies ranged through those of mathematician, physician, biologist, physicist, chemist, astrologer, astronomer, philosopher, writer, and gambler. He was one of the most influential mathematicians of the Renaissance, and was one of the key figures in the foundation of probability and the earliest introducer of the binomial coefficients and the binomial theorem in the Western world. He wrote more than 200 works on science. Cardano partially invented and described several mechanical devices including the combination lock, the gimbal consisting of three concentric rings allowing a supported compass or gyroscope to rotate freely, and the Cardan shaft with universal joints, which allows the transmission of rotary motion at various angles and is used in vehicles to this day. He made sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Ernest
John Ernest (May 6, 1922 – July 21, 1994) was an American-born constructivist abstract artist. He was born in Philadelphia, in 1922. After living and working in Sweden and Paris from 1946 to 1951, he moved to London, England, where he lived and worked from 1951. As a mature student at Saint Martin's School of Art he came under the influence of Victor Pasmore and other proponents of constructivism. During the 1950s together with Anthony Hill, Kenneth Martin, Mary Martin, Stephen Gilbert and Gillian Wise he became a key member of the British constructivist (a.k.a. constructionist) art movement. Ernest created both reliefs and free standing constructions. Several of his works are held at Tate Britain, including the Moebius Strip sculpture. He designed both a tower and a large wall relief at the International Union of Architects congress, South Bank, London, 1961. The exhibition structure also housed works by several of the other British constructivists. Ernest had a lifelong fasc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albrecht Dürer
Albrecht Dürer (; ; hu, Ajtósi Adalbert; 21 May 1471 – 6 April 1528),Müller, Peter O. (1993) ''Substantiv-Derivation in Den Schriften Albrecht Dürers'', Walter de Gruyter. . sometimes spelled in English as Durer (without an umlaut) or Duerer, was a German painter, printmaker, and theorist of the German Renaissance. Born in Nuremberg, Dürer established his reputation and influence across Europe in his twenties due to his high-quality woodcut prints. He was in contact with the major Italian artists of his time, including Raphael, Giovanni Bellini, and Leonardo da Vinci, and from 1512 was patronized by Emperor Maximilian I. Dürer's vast body of work includes engravings, his preferred technique in his later prints, altarpieces, portraits and self-portraits, watercolours and books. The woodcuts series are more Gothic than the rest of his work. His well-known engravings include the three '' Meisterstiche'' (master prints) ''Knight, Death and the Devil'' (1513), '' Sain ...

Henry Dudeney
Henry Ernest Dudeney (10 April 1857 – 23 April 1930) was an English author and mathematician who specialised in logic puzzles and mathematical games. He is known as one of the country's foremost creators of mathematical puzzles. Early life Dudeney was born in the village of Mayfield, East Sussex, England, one of six children of Gilbert and Lucy Dudeney. His grandfather, John Dudeney, was well known as a self-taught mathematician and shepherd; his initiative was much admired by his grandson. Dudeney learned to play chess at an early age, and continued to play frequently throughout his life. This led to a marked interest in mathematics and the composition of puzzles. Chess problems in particular fascinated him during his early years. Career Although Dudeney spent his career in the Civil Service, he continued to devise various problems and puzzles. Dudeney's first puzzle contributions were submissions to newspapers and magazines, often under the pseudonym of "Sphinx." Much of ...

Harvey Dubner
Harvey Dubner (1928–2019) was an electrical engineer and mathematician who lived in New Jersey, noted for his contributions to finding large prime numbers. In 1984, he and his son Robert collaborated in developing the 'Dubner cruncher', a board which used a commercial finite impulse response filter chip to speed up dramatically the multiplication of medium-sized multi-precision numbers, to levels competitive with supercomputers of the time, though his focus later changed to efficient implementation of FFT-based algorithms on personal computers. He found many large prime numbers of special forms: repunits, Fibonacci primes, prime Lucas numbers, twin primes, Sophie Germain primes, Belphegor's prime, and primes in arithmetic progression In number theory, primes in arithmetic progression are any sequence of at least three prime numbers that are consecutive terms in an arithmetic progression. An example is the sequence of primes (3, 7, 11), which is given by a_n = 3 + 4n for 0 \ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humphry Ditton
Humphry Ditton (29 May 1675 – 15 October 1715) was an English mathematician. He was the author of several influential works. Life Ditton was born on 29 May 1675 in Salisbury, the only son of Humphry Ditton, gentleman and ardent nonconformist, and Miss Luttrell of Dunster Castle, near Taunton. He studied theology privately, and was for some time also a dissenting minister, at Tonbridge, where he married a Miss Ball.Raymond Flood: "Ditton, Humphry umphrey, ODNBRetrieved 29 May 2021./ref> On his father's death, Ditton devoted himself mainly to the study of mathematics. Through the influence of Isaac Newton he was elected mathematical master in Christ's Hospital. He produced also a theological work, ''A Discourse Concerning the Resurrection of Jesus Christ'', which sought to take a mathematical, deductive approach to the subject. The first of its four editions appeared in 1712 and it was translated into French and German. He was unable to complete his response to various criticis ...

William Crabtree
William Crabtree (1610–1644) was an astronomer, mathematician, and merchant from Broughton, then in the Hundred of Salford, Lancashire, England. He was one of only two people to observe and record the first predicted transit of Venus in 1639. Life and work Crabtree was born in 1610 in the hamlet of Broughton Spout, which was on the east bank of the River Irwell, near the area now known as "The Priory" in Broughton, Salford and was educated at the Manchester Grammar School. He married into a wealthy family and worked as a merchant in Manchester. In his spare time, his great interest was astronomy. He carefully measured the movements of the planets and undertook precise astronomical calculations. With improved accuracy, he rewrote the existing Rudolphine Tables of Planetary Positions.
