Glossary of Mathematical Terms (Story of Mathematics)


Mathematics is the study of quantity, space, structure, and change. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity. The research required to solve mathematical problems can take years or even centuries of sustained inquiry. Since the pioneering work of Giuseppe Peano, David Hilbert, and others on axiomatic systems in the late 19th century, it has become customary to view mathematical research as establishing truth by rigorous deduction from appropriately chosen axioms and definitions. When those mathematical structures are good models of real phenomena, then mathematical reasoning often provides insight or predictions. Through the use of abstraction and logical reasoning, mathematics evolved from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity for as far back as written records exist. Rigorous arguments first appeared in Greek mathematics, most notably in Euclid’s Elements. Mathematics continued to develop, for example in China in 300 BC, in India in AD 100, and in the Muslim world in AD 800, until the Renaissance, when mathematical innovations interacting with new scientific discoveries led to a rapid increase in the rate of mathematical discovery that continues to the present day. — Wikipedia (Math Skills)

    on September 19, 2017 at 4:00 am

    (Society for Research in Child Development) A new longitudinal study looked at how youths' self-concepts are linked to their actual academic achievement in math and reading from middle childhood to adolescence. The study found that students' self-concepts of their abilities in these two academic domains play an important role in motivating their achievements over time and across levels of achievement. […]

  • Mathematician and chronicler of political murders
    on September 19, 2017 at 4:00 am

    (Technical University of Munich (TUM)) Emil J. Gumbel's formulas are fundamental for extreme value theory. This statistical discipline describes extreme incidents, such as floods or storms. Little is known, however, that he was also a pioneer of modern data journalism, unveiling the patterns of political murder in the Weimar Republic. Professor Matthias Scherer and his team at the Technical University of Munich (TUM) now intend to fill in the gaps in what the world knows about Gumbel. […]

  • Monk parakeets invade Mexico

    (Santa Fe Institute) In a new paper published in PLOS ONE, researchers describe a recent, rapid, and ongoing invasion of monk parakeets in Mexico, and the regulatory changes that affected the species' spread. […]

    (Faculty of Science - University of Copenhagen) Researchers from the Department of Food Science (FOOD) at the University of Copenhagen in Denmark are the first in the world to have analysed whole grains with long near-infrared wavelengths using a new type of light source, the supercontinuum laser. The research has significance for our knowledge of food ingredients and may, for example, eventually lead to better quality of bread and beer. […]

    on September 19, 2017 at 4:00 am

    (NOAA Northeast Fisheries Science Center) NOAA Fisheries researchers and colleagues at the New England Aquarium have developed a new model to improve estimates of abundance and population trends of endangered North Atlantic right whales, which have declined in numbers and productivity in recent years. Between 1990 and 2010 abundance increased to 482 animals, but since 2010 the numbers have declined to 458 in 2015, with 14 known deaths this year. The findings were published in the journal […]
