Mathematicians of April and May

As promised in the post The Power of Organization, here is the post with the mathematicians I wrote this month and also last month. Hope you will find it useful and interesting. Lets get going:

  • Leonard Euler, born on 15th April 1707. Euler introduced and popularized several notational conventions through his numerous and widely circulated textbooks. Most notably, he introduced the concept of a function and was the first to write f(x) to denote the function f applied to the argument x. He also introduced the modern notation for the trigonometric functions, the letter e for the base of the natural logarithm (now also known as Euler’s number), the Greek letter Σ for summations and the letter i to denote the imaginary unit. The use of the Greek letter π to denote the ratio of a circle’s circumference to its diameter was also popularized by Euler, although it did not originate with him. If you are interested in more about his life I recommend reading Euler : The Master of Us All by William Dunham. The book is nicely structured so that you can read only those subjects you are mostly interested, this makes it a perfect biography.

  • Rudolf Lipschitz born on 14 May 1832 was a German mathematician and professor at the University of Bonn from 1864. For the more passionate ones, Dirichlet was his teacher. He supervised the early work of Felix Klein (another known mathematician especially for his work in group theory: klein four-group). While Lipschitz gave his name to the Lipschitz continuity condition (I’ve used this a lot in analysis, my most used book was Real Analysis (Springer Undergraduate Mathematics Series) by John M. Howie), he also worked in other areas (number theory, algebras with involution, mathematical analysis, differential geometry and classical mechanics). 11257063_1050783644950705_1961363352654570242_n
  • Albrecht Dürer born on 21 May 1471 was a German painter, print-maker, mathematician, and theorist. His work on geometry is called the “Four Books on Measurement”. He wrote about linear geometry (Dürer’s geometric constructions include helices, conchoids and epicycloids) and two dimensional geometry (i.e. the construction of regular polygons).
    But he is mostly know for the engraving ” Melancolia I” because it was the subject of a lot of interpretations. One of them states that the image explain mathematical knowledge from Durer’s point of view: “Mathematical knowledge is referenced by the use of the symbols: compass, geometrical solid, magic square, scale, hourglass”. The magic square from the image is well-known and also the truncated rhombohedron is now known as Dürer’s solid. If you are interested in more of his art work check Albrecht Dürer: Collector’s Edition Art Gallery ^_^

  • Milutin Milanković born on 28th May 1879. He was a Serbian mathematician, astronomer, climatologist, geophysicist and much more. Milanković gave two fundamental contributions to global science. He used made the connection between mathematics and other sciences, such as geography and geology.
    He wrote and published seven papers on mathematical theories of climate both on the Earth and on the other planets. He formulated a precise, numerical climatological model with the capacity for reconstruction of the past and prediction of the future, and established the astronomical theory of climate as a generalized mathematical theory of insolation. 11014966_1069208469774889_4822910518939177119_n

Hope you are enjoying my new series. I will probably be once a month or once every 2 months. If you have a favorite mathematician you want me to write about let me know in comment box bellow. 

Have a nice day. Thank you for your help and support. Thank you for reading. You can find me on FacebookTumblr, Google+,  Twitter  and  Instagram, I will try to post there as often as possible. Don’t forget that maths is everywhere! Enjoy!

  1. Thank you very much.Most enjoyable.Do you know anything about the chinese mathematician Wang Xuan? This year the chinese post office produced a memorial stamp with him on the stamp-he passed away in 2006. Being a collector of mathematical stamps I was glad for the information on Milutin Milanković and Durer.
    Best Wishes Johnny Oberman Israel

    1. Don’t know much about Wang Xuan, but I will find out. So many great mathematicians not everyone knows about, that is why I am doing this mathematicians of the month posts. They will be on every month ^_^
      Thanks for your support 🙂
