Shoelace Maths

Previously I have commented on a mathematical approach to the tying of neckties. Now NewScientist have released an article on optimal tying of shoelaces. What can one say? People just have too much time! ;)... [Read article]

Mathematics Incomplete?

Mainstream mathematicians tend to like to believe that everything in this world can be explained, and proved, by use of logic or mathematics if you want. I guess I did too, atleast up until a professor gave me the name of Kurt Gödel... Kurt Gödel (1906-1978) was the name of... [Read article]

Minimize Change

Have you ever been to another country, using a new currency for the first time? The standard problem is naturally that it is very easy to use the notes and the bigger (in terms of value) coins, ending up with a whole mess of more or less valuable coins. Searching... [Read article]

Neckties

Isn't it funny how many simple things can be made hard by just applying mathematics to the problem? This time around it is the standard issue necktie. Thomas Fink and Yong Mao wrote an article for Nature about a mathematical model to calculate and classify all possible tie knots. They... [Read article]
