Cuthbert Edmund Cullis
Cuthbert Edmund Cullis (15 April 1868 – 20 March 1954) was an English mathematician who worked as a professor of mathematics at the University of Calcutta and was influential in standardizing notation and conventions in the algebra of matrices and determinants. Life and work Cullis was the son of Frederick John, a dock surveyor in Gloucester and Louisa (née Corbett) Cullis. One of his two sisters, Winifred C. Cullis, became a physiologist. He was educated at King Edward High School, Birmingham after which he joined Caius College, Cambridge.

C E Cullis
C, or c, is the third letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''cee'' (pronounced ), plural ''cees''. History "C" comes from the same letter as "G". The Semites named it gimel. The sign is possibly adapted from an Egyptian hieroglyph for a staff sling, which may have been the meaning of the name ''gimel''. Another possibility is that it depicted a camel, the Semitic name for which was ''gamal''. Barry B. Powell, a specialist in the history of writing, states "It is hard to imagine how gimel = "camel" can be derived from the picture of a camel (it may show his hump, or his head and neck!)". In the Etruscan language, plosive consonants had no contrastive voicing, so the Greek ' Γ' (Gamma) was adopted into the Etruscan alphabet to represent . Already in the Western Greek alphabet, Gamma first took a '' form in Early Etruscan, then '' in Classical Etru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Winifred Cullis
Winifred Cullis (2 June 1875 – 13 November 1956) was a physiologist and academic, and the first woman to hold a professorial chair at a medical school. Early life and education Born in Gloucester, Winifred was the youngest daughter of the six children of Frederick John and Louisa (née Corbett) Cullis. Her brother Cuthbert Edmund Cullis became a mathematician. The family moved to Birmingham in 1880. She was initially educated at a middle school, the Summer Hill School, and at 16 transferred to the associated King Edward VI High School for Girls, Birmingham and took extra science classes at Mason College. She entered Newnham College, Cambridge in 1896, financed by a Sidgwick scholarship, and achieved a second in both parts of the natural sciences tripos (1899 and 1900). While an undergraduate student she was supervised in the Physiological Laboratory by John Newport Langley. She was not awarded a degree since Cambridge did not award degrees to women at this time.

Gonville And Caius College, Cambridge
Gonville and Caius College, commonly known as Caius ( ), is a constituent college of the University of Cambridge in Cambridge, England.

Wrangler (University Of Cambridge)
At the University of Cambridge in England, a "Wrangler" is a student who gains first-class honours in the Mathematical Tripos competition. The highest-scoring student is the Senior Wrangler, the second highest is the Second Wrangler, and so on. By contrast, the person who achieves the lowest exam marks while still earning a third-class honours degree (that is, while still earning an honours degree at all) is known as the Wooden spoon (award), wooden spoon. History Until 1909, the university made the rankings public. Since 1910, it has publicly revealed only the class of degree gained by each student. An examiner reveals the identity of the Senior Wrangler "unofficially" by tipping his hat when reading out the person's name, but other rankings are communicated to each student privately. Therefore, the names of only some 20th-century Senior Wrangler (University of Cambridge)#Senior Wranglers since 1910, Senior Wranglers (such as Crispin Nash-Williams, Christopher Budd (mathematicia ...

University Of Jena
The University of Jena, officially the Friedrich Schiller University Jena (, abbreviated FSU, shortened form ''Uni Jena''), is a public research university located in Jena, Thuringia, Germany. The university was established in 1558 and is counted among the ten oldest universities in Germany. It is affiliated with six Nobel Prize winners, most recently in 2000 when Jena graduate Herbert Kroemer won the Nobel Prize for physics. It was renamed after the poet Friedrich Schiller who was teaching as professor of philosophy when Jena attracted some of the most influential minds at the turn of the 19th century. With Karl Leonhard Reinhold, Johann Gottlieb Fichte, G. W. F. Hegel, F. W. J. Schelling and Friedrich Schlegel on its teaching staff, the university was at the centre of the emergence of German idealism and early Romanticism. , the university has around 19,000 students enrolled and 375 professors.

Möbius Strip
In mathematics, a Möbius strip, Möbius band, or Möbius loop is a Surface (topology), surface that can be formed by attaching the ends of a strip of paper together with a half-twist. As a mathematical object, it was discovered by Johann Benedict Listing and August Ferdinand Möbius in 1858, but it had already appeared in Ancient Rome, Roman mosaics from the third century Common Era, CE. The Möbius strip is a orientability, non-orientable surface, meaning that within it one cannot consistently distinguish clockwise from counterclockwise turns. Every non-orientable surface contains a Möbius strip. As an abstract topological space, the Möbius strip can be embedded into three-dimensional Euclidean space in many different ways: a clockwise half-twist is different from a counterclockwise half-twist, and it can also be embedded with odd numbers of twists greater than one, or with a Knot (mathematics), knotted centerline. Any two embeddings with the same knot for the centerline and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Determinant
In mathematics, the determinant is a Scalar (mathematics), scalar-valued function (mathematics), function of the entries of a square matrix. The determinant of a matrix is commonly denoted , , or . Its value characterizes some properties of the matrix and the linear map represented, on a given basis (linear algebra), basis, by the matrix. In particular, the determinant is nonzero if and only if the matrix is invertible matrix, invertible and the corresponding linear map is an linear isomorphism, isomorphism. However, if the determinant is zero, the matrix is referred to as singular, meaning it does not have an inverse. The determinant is completely determined by the two following properties: the determinant of a product of matrices is the product of their determinants, and the determinant of a triangular matrix is the product of its diagonal entries. The determinant of a matrix is :\begin a & b\\c & d \end=ad-bc, and the determinant of a matrix is : \begin a & b & c \\ d & e ...
