Japanese Site Map Department of Math. Hokkaido Univ. 21st Century COE Program : Mathematics of Nonlinear Structure via Singularity Hokkaido Mathematical Journal Hokkaido Mathematical Journal, one of the world-leading mathematical academic journals available in English, is published by the Department of Mathematics, Hokkaido University. The journal grew out of Series I, Mathematics, originally published from 1930 to 1972 as part of the Journal of Faculty of Science, Hokkaido University. In 1972, we started our own publication-what is now known as Hokkaido Mathematics Journal. Our department publishes the journal three times a year, with an annual volume comprising a total of nearly 600 pages. Each volume contains about 40 excellent research papers by mathematicians without regard to their fields, nationalities, or affiliations. For the past three years, an average of some 85 papers have been contributed to our journal annually. More than half of them were from contributors in some 20 different countries. In principle, all contributions are refereed and the final decisions are made based on the reports from the referees. The journal is available at about 200 libraries and research institutions in Japan and 400 universities and institutions abroad.

American geologist whose studies on the origins of volcanic rocks contributed to the understanding of the formation of the Earth. In Yellowstone National Park, he discovered that the volcanic eruptions that formed Yellowstone Plateau produced rocks of an unusual type, called welded tuff. In the 1960s, he helped develop the Boyd-English device, a piston-cylinder laboratory apparatus to simulate the pressure exerted on minerals deep within the Earth. Able to create a synthetic diamond, it also helps scientists determine the nature of minerals in the various rock layers of the Earth. He was a leading authority on the mantle root of the 3.5-billion-year-old Kaapvaal craton (the kernel on which a continent grows) rock in southern Africa. Polykarp Kusch (source) Born 26 Jan 1911; died 20 Mar 1993. German-American physicist who shared the Nobel Prize for Physics in 1955 for his accurate determination that the magnetic moment of the electron is greater than its theoretical value. This he deduced from researching the hyperfine structure of the energy levels in certain elements, and in 1947 found a discrepancy of about 0.1% between the observed value and that predicted by theory. Although minute, this anomaly was of great significance to theories of the interactions of electrons and electromagnetic radiation, now known as quantum electrodynamics. (He shared the prize with Willis E. Lamb, Jr. who performed independent but related experiments at Columbia University on the hyperfine structure of the hydrogen atom.)

103. Currency Chaos Three hundred years later the Bank of England is employing a consortium of englishmathematicians to bring disorder and CHAOS to the english currency. http://www.maths.uq.edu.au/~infinity/Infinity9/Currency.html

In 1696 the famous mathematician and scholar Isaac Newton was employed by the English Mint (now the Bank of England) to bring order to the English currency. Three hundred years later the Bank of England is employing a consortium of English mathematicians to bring disorder and CHAOS to the English currency. If you take an Australian $5 note, hold it between your fingers, with the Queen facing you, and then lift the note to the light, in the top left-hand corner you will see a very faint image of the Australian emblem. It is a watermark that has been embedded in the note during manufacture. In the past, it has been difficult to forge watermarks, and so they have provided some protection against counterfeiting. However, this is no longer true as criminals can use sophisticated scanning devices coupled with powerful computers to create forged notes. To counter this the Bank of England are considering partially 'hiding' the watermark with a random set of dots. Minute microdots will be placed, apparently randomly, on top of the watermark, creating a mask to hide it. Sometimes, the mask is like a complex fractal and is generated through fractal modulation.

Answer: Archimedes 2. Which English mathematician who became the Lucasian Professor of Mathematics invented calculus? Answer: Sir Isaac Newton 3. Which French mathematician is famous for his phrase, "I think, therefore I am?" Answer: Rene Descartes 4. Which English mathematician of the nineteenth century is known for his invention of a machine which could not only perform the ordinary processes of arithmetic, but could tabulate the values of any function and print the results? (Hint: A computer software store was named after him.) Answer: Charles Babbage 5. This Italian mathematician lived during the Middle Ages and popularized the modern decimal system of numerals. His name describes a sequence where each number is equal to the sum of the previous two numbers.
