Jay Hambidge
Jay Hambidge (1867–1924) was a Canadian-born American artist who formulated the theory of "dynamic symmetry", a system defining compositional rules, which was adopted by several notable American and Canadian artists in the early 20th century. Early life and theory He was a pupil at the Art Students' League in New York and of William Merritt Chase, and a thorough student of classical art. He conceived the idea that the study of arithmetic with the aid of geometrical designs was the foundation of the proportion and symmetry in Greek architecture, sculpture and ceramics. Careful examination and measurements of classical buildings in Greece, among them the Parthenon, the temple of Apollo at Bassæ, of Zeus at Olympia and Athenæ at Ægina, prompted him to formulate the theory of "dynamic symmetry" as demonstrated in his works ''Dynamic Symmetry: The Greek Vase'' (1920) and ''The Elements of Dynamic Symmetry'' (1926). It created a great deal of discussion. He found a disciple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Journal Of Archaeology
The ''American Journal of Archaeology'' (AJA), the peer-reviewed journal of the Archaeological Institute of America, has been published since 1897 (continuing the ''American Journal of Archaeology and of the History of the Fine Arts'' founded by the institute in 1885). The publication was co-founded in 1885 by Princeton University professors Arthur Frothingham and Allan Marquand. Frothingham became the first editor, serving until 1896. The journal primarily features articles about the art and archaeology of Europe and the Mediterranean world, including the Near East and Egypt, from prehistoric to Late Antique times. It also publishes book reviews, museum exhibition reviews, and necrologies. It is published in January, April, July, and October each year in print and electronic editions. The journal's current editor-in-chief is Jane B. Carter. The journal's first woman editor-in-chief was Mary Hamilton Swindler. From 1940 to 1950 the journal published articles by Michael Ventris, ...

Elizabeth Whiteley
Elizabeth Whiteley (born 1945) is an American fine artist and designer. Early life and education Whiteley was born in Erie, Pennsylvania, US, in 1945. Whiteley earned a B.A. degree from Carnegie Mellon University (CMU), and a M.S. in library science from Case Western Reserve University (CWRU). She received a B.F.A. from the School of the Art Institute of Chicago (SAIC). Career Whiteley concentrates on the connections between mathematics and art, with an emphasis on seeking geometric principles related to rectangles, triangles, and squares. They form the basis for her work with various genres in the visual arts. As part of a critic's residency essay, David Carrier wrote about her work "I understood better how her images were produced by seeing the grid she used to compose. This apparent way of restricting her composition actually gave her the freedom to choose where to set her patterns." Paintings, drawings, and sculpture Since 1988, she has used the geometric design ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert McCloskey
John Robert McCloskey (September 15, 1914 – June 30, 2003) was an American writer and illustrator of children's books. He both wrote and illustrated eight picture books, and won two Caldecott Medals from the American Library Association for the year's best-illustrated picture book. Four of the eight books were set in Maine: ''Blueberries for Sal'', ''One Morning in Maine'', ''Time of Wonder'', and ''Burt Dow, Deep-water Man'' (the last three of those four were all set on the coast). His best-known work is ''Make Way For Ducklings'', set in Boston. In longer works, he both wrote and illustrated ''Homer Price'' and he illustrated Keith Robertson's '' Henry Reed'' series. Personal life McCloskey was born in Hamilton, Ohio, on September 15, 1914 to Howard and Mabel McCloskey. He had two sisters, Melba and Dorothy. As a teen, McCloskey was a camper-turned-counselor at Camp Campbell Gard, where at age 16 he carved a totem pole which stood at the camp for over 50 years. His work on t ...

Kathleen Munn
Kathleen Jean Munn (1887– October 19, 1974) is recognized today as a pioneer of Modern art, modern art in Canada, though she remained on the periphery of the Canadian art scene during her lifetime. She imagined conventional subjects in a radically new visual vocabulary as she combined the traditions of European art with modern art studies in New York. She died at age eighty-seven, unaware that her long-held hope for “a possible future for my work” was about to become reality. Early years Kathleen Jean Munn was born to a middle-class family in Toronto in 1887 and was the youngest of six children. Her family owned and ran a jewellery store at the intersection of Yonge and Bloor, and the family lived in the apartment above. Munn began her formal art education in 1904 when she began attending the Westbourne School in Toronto, studying under Farquhar McGillivray Knowles. Beginning in 1909, she began to show her work in exhibitions with the Ontario Society of Artists, the Royal C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helen Hokinson
Helen Elna Hokinson (June 29, 1893 – November 1, 1949) was an American cartoonist and a staff cartoonist for ''The New Yorker''.

Maxfield Parrish
Maxfield Parrish (July 25, 1870 – March 30, 1966) was an American painter and illustration, illustrator active in the first half of the 20th century. He is known for his distinctive saturated hues and idealized neo-classical imagery. His career spanned fifty years and was wildly successful: the National Museum of American Illustration deemed his painting ''Daybreak (painting), Daybreak'' (1922) to be the most successful art print of the 20th century. Early life and education Maxfield Parrish was born in Philadelphia, Pennsylvania, to painter and etcher Stephen Parrish and Elizabeth Bancroft. His given name was Frederick Parrish, but he later adopted Maxfield, his paternal grandmother's maiden name, as his middle, then finally as his professional name. He was raised in a Quaker society. As a child he began drawing for his own amusement, showed talent, and his parents encouraged him. Between 1884 and 1886, his parents took Parrish to Europe, where he toured England, Italy, ...

Generalizations Of Fibonacci Numbers
In mathematics, the Fibonacci numbers form a sequence defined recursively by: :F_n = \begin 0 & n = 0 \\ 1 & n = 1 \\ F_ + F_ & n > 1 \end That is, after two starting values, each number is the sum of the two preceding numbers. The Fibonacci sequence has been studied extensively and generalized in many ways, for example, by starting with other numbers than 0 and 1, by adding more than two numbers to generate the next number, or by adding objects other than numbers. Extension to negative integers Using F_ = F_n - F_, one can extend the Fibonacci numbers to negative integers. So we get: :... −8, 5, −3, 2, −1, 1, 0, 1, 1, 2, 3, 5, 8, ... and F_ = (-1)^ F_n. See also NegaFibonacci coding. Extension to all real or complex numbers There are a number of possible generalizations of the Fibonacci numbers which include the real numbers (and sometimes the complex numbers) in their domain. These each involve the golden ratio , and are based on Binet's formula :F_n = \frac. The ana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibonacci Sequence
In mathematics, the Fibonacci numbers, commonly denoted , form a integer sequence, sequence, the Fibonacci sequence, in which each number is the sum of the two preceding ones. The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes (as did Fibonacci) from 1 and 2. Starting from 0 and 1, the first few values in the sequence are: :0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144. The Fibonacci numbers were first described in Indian mathematics, as early as 200 BC in work by Pingala on enumerating possible patterns of Sanskrit poetry formed from syllables of two lengths. They are named after the Italian mathematician Leonardo of Pisa, later known as Fibonacci, who introduced the sequence to Western European mathematics in his 1202 book ''Liber Abaci''. Fibonacci numbers appear unexpectedly often in mathematics, so much so that there is an entire journal dedicated to their study, the ''Fibonacci Quarterly''. Applications of Fibonacci ...

Phyllotaxis
In botany, phyllotaxis () or phyllotaxy is the arrangement of leaf, leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature. Leaf arrangement The basic leaf#Arrangement on the stem, arrangements of leaves on a stem are opposite and alternate (also known as spiral). Leaves may also be Whorl (botany), whorled if several leaves arise, or appear to arise, from the same level (at the same Node (botany), node) on a stem. With an opposite leaf arrangement, two leaves arise from the stem at the same level (at the same Node (botany), node), on opposite sides of the stem. An opposite leaf pair can be thought of as a whorl of two leaves. With an alternate (spiral) pattern, each leaf arises at a different point (node) on the stem. Distichous phyllotaxis, also called "two-ranked leaf arrangement" is a special case of either opposite or alternate leaf arrangement where the leaves on a stem are arranged in two vertical columns on opposite sides of t ...

Silver Ratio
In mathematics, two quantities are in the silver ratio (or silver mean) if the ratio of the smaller of those two quantities to the larger quantity is the same as the ratio of the larger quantity to the sum of the smaller quantity and twice the larger quantity (see below). This defines the silver ratio as an irrational mathematical constant, whose value of one plus the square root of 2 is approximately 2.4142135623. Its name is an allusion to the golden ratio; analogously to the way the golden ratio is the limiting ratio of consecutive Fibonacci numbers, the silver ratio is the limiting ratio of consecutive Pell numbers. The silver ratio is denoted by . Mathematicians have studied the silver ratio since the time of the Greeks (although perhaps without giving a special name until recently) because of its connections to the square root of 2, its convergents, square triangular numbers, Pell numbers, octagons and the like. The relation described above can be expressed algebraical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
