We all understand them and we use them countless times every day . So what could be nicer than discovering interesting patterns within them What secrets do the natural numbers hold Endre Szemerédi one of the main speakers at this year's British Mathematical Colloquium BMC and winner of the 2012 Abel prize is interested in the simplest kind of pattern you can find within a collection of natural numbers : sequences of numbers that are all evenly spaced , with successive numbers all having the same distance between them . Examples are

  • The Virtue of Laziness

    Updated: 2014-04-11 16:42:06
    My son, Alexey Radul, is a programmer. He taught me the importance of laziness in programming. One of his rules: Not to write the same line of code in the same program twice. If you need the same line of code in the same program, that means you should either use a loop or outsource [...]

    This is one of my favorite jokes: Three logicians walk into a bar. The waitress asks, “Do you all want beer?” The first logician answers, “I do not know.” The second logician answers, “I do not know.” The third logician answers, “Yes.” This joke reminds me of hat puzzles. In the joke each logician knows whether or [...]

  • Diseases, maths and illegal numbers

    Updated: 2014-04-08 17:12:12
    If you're not sure how maths is relevant to real life, then go to see this year's popular lectures put on by the London Mathematical Society. Kevin Buzzard of Imperial College will explore the digitisation of our lives — the fact that many of the things we enjoy and work with are now stored on computers which reduce them to numbers. This has weird consequences. For example, some numbers are copyrighted, and there are even some illegal prime numbers.read more

    Updated: 2014-04-07 06:35:37
    My favorite kind of Math challenges are those that children can understand and professional mathematicians can't solve easily (or at all.) Math Bytes: Google Bombs, Chocolate-Covered Pi, and Other Cool Bits in Computing is a brand new book from Princeton University Press that has a great collection of fun problems that kids (middle school and […]
