Commission Jean Audouze the president of International Mathematical Union Ingrid Daubechies the Fields medalist Wendelin Werner and the president of the European Mathematical Society Marta Sanz Solé Then Christiane Rousseau from Montreal the coordinator of MPE2013 gave a survey on the initiatives that are planned in this year The next item of the agenda was the presentation of the open source platform IMAGINARY by Martin Greuel see the next picture and Andreas Matt Finally at the end of the morning session the winners of the MPE2013 competition were announced in a ceremony moderated by Ehrhard Behrends chair of the jury the pdf of his talk can be found here Third prize 2000 How to predict the future of glaciers by the team of Guilleaume Jouvet France Switzerland Germany In an entertaining way this video illustrates the collaboration between a mathematician and a glacier expert as they develop a dynamic model for the evolution of glaciers At the end of the video the user can choose among alternative scenarios to see possible futures for the Aletsch glacier in the Alps From the minutes of the meeting of the jury In the picture E Behrends G Jouvet Ch Rousseau Second prize 3000 Dune Ash by the team of Tobias Malkmus Germany This interactive computer program graphically simulates the dispersion of a volcanic ash cloud using a mathematical model The user chooses the location of the volcano sketches the direction and strength of the winds and sets the rate of dispersion An original interface allows the user to specify complex wind patterns and invites repeated exploration From the minutes of the meeting of the jury In the picture E Behrends two members of the Malkmus team Ch Rousseau First prize 5000 Sphere of the Earth by the team of Daniel Ramos Spain This

the different ways of lacing shoes It is a question that surprises people For most of us there is only one acceptable method of lacing shoes However the reality is that people in different cultures use different patterns to lace their shoes To give only two examples there are the methods used in the USA and in Europe which are the most common ways In the former the shoelaces are threaded in opposing zigzags and when seen from above they seem to be crossed In the latter they are threaded in alternating zigzags in such a way that the eyes of the shoes seem joined horizontally by the shoelaces when viewed from above There is also the ex factory method in which the shoelace makes a continual zigzag from top to bottom and then returns in a diagonal line Which do you think is the most efficient method The first curious fact is that there are an astronomical number of options For shoes with two rows of five eyes Polster verified that there are 51 840 different ways to thread the laces This number increases to millions when the number of eyes rises Polster restricted himself to ways of threading the laces that necessarily occupy all the eyes and allow the eyes to be pulled together by applying pressure to the laces for example this implies that the laces may not pass through three successive eyes on the same side as this would not exert any individual pressure on the eye in the middle Then he defined the efficiency criteria He stated that the security of the binding should be maximized and the compression of the laces should be minimized Comparing the three above mentioned systems he verified that the most economical is always the American method with the second best system depending on the number of eyes If there are four or more pairs of eyes the European method is superior to the ex factory method In the case of three pairs of eyes they are equal And in the case of only one or two pairs of eyes the problem is trivial as all three methods are equally good If you try to verify this you will see that it is not difficult American method European method Ex factory method Bow tie method Four different ways to lace your shoes However Polster did not restrict himself to studying only these three methods He analyzed the problem from a general perspective only taking the above mentioned restrictions into account He discovered that the most economical system is not one of the three commonly used methods He discovered a less common pathway that he called the bow tie method As far as the criterion of maximum security of the binding was concerned he did not find any esoteric method which is comforting After all the American and ex factory methods are the best When the rows of eyes are farther apart the ex factory method is the strongest When the
