• 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 [...]

  • Beer Jokes and Hat Puzzles

    Updated: 2014-04-11 16:39:45
    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

  • Tim Chartier – Inspired by Math #34

    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 […]

One of the greatest aims of theoretical physics is to describe all of these forces and particles in one all-encompassing theory . Something called quantum field theory has been hugely successful in this context , but what exactly is it And does it answer all the questions Based on interviews with some of the main players in theoretical physics , this series of accessible articles traces the history of quantum field theory , from its inception at the beginning of the twentieth century to the
