studied 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 same way when you tread upon an orange peel on a table it breaks and deforms the map makers have to deform the globe in order to reproduce a spherical surface on a plane Deformations are not serious for small areas But the world became bigger with the travels of Discoveries and continent and ocean maps necessary to navigation started being made Mercator naturally knew the results of Pedro Nunes once they were very spread through all Europe He decided to make a chart that would be directly useful to the navigators As first principle he decided the chart would show a lattice in which the lines of the same latitude were all parallel to the Equator and perpendicular to the meridians and in which meridians were all parallel to each other In this sense he only followed Pedro Nunes indications who proposed some alterations to the rectangular charts i e to the maps with squares marked by parallels and meridians As a second principle Mercator decided that the route lines would appear as straight lines and again he did not do more here than following a suggestion given by Pedro Nunes In order to realize this principle Mercator progressively augmented the distances between the parallels while the latitude approaches the Poles Once more he was following a suggestion given by the Portuguese mathematician who talked about the need of distorting the latitudes scale in order to build a chart where the loxodromes were straight lines And so was born Mercator s projection which keeps being today the most well known and the most used Pedro Nunes A mathematician in a country of navigators Ayrıntılar Kategori Uncategorised PEDRO NUNES A MATHEMATICIAN IN A COUNTRY OF NAVIGATORS The Portuguese dared to venture at the great ocean sea wrote Pedro Nunes they discovered new islands new lands new seas new people and more than that new skies new stars Text by Nuno Crato The greatest mathematician of Discoveries era was born 500 years ago in the city of Alcácer do Sal We know very little about his origins and about his life and we considerably ignore what sort of connections he had with the scientists of his time However it is possible to reconstitute his work through his publications and the many references made to him by the great intellectuals of his time He was called Pedro Nunes and this was how he signed but very often his name appears under the Latinised form Petrus Nonius We only know the year of his birth we know neither the month nor the day We know the exact date of his death which happened the 11th August 1578 His life like the one of Camões 1524 1580 coincided with the greatest historical period of our country A short time after the dead of these great Portuguese Felipe II from Spain ascended the throne and the country lost its independence which it would only retake in 1640 By that time the epoch in which Portugal and Spain incontestably dominated the seas was over In the Iberian Peninsula Mathematics and Sciences had also lost their major greatness It seems that Pedro Nunes had Jew origins once Damião de Góis described him as a Portuguese of nation reference usually applied to converted Jews But there is nothing in Pedro Nunes writings that show any signs of crypto Judaism and the few religious references we can find in them are clearly Christian Neither there are any signs of Nunes having ever been persecuted Kings and princes have protected him during all his life However his grandchildren spent some years in the prisons of the Inquisition accused of professing Judaism As the Italian mathematician Francisco Maurolico 1494 1575 Pedro Nunes worked in the period between Regiomontano 1436 1476 and Viète 1544 1603 As the astronomer Tycho Brahe 1546 1601 and the cosmographer Cristophorus Clavius 1538 1612 he lived in the period between Copernicus 1473 1543 and Galileo 1564 1642 Stuck between these great figures who determined turning moments of Mathematics and Sciences the work of Pedro Nunes has been less studied than what it deserves But in his time its contributions were entirely recognized till the end of his life Nunes was practically dying when he was urged by the Pope messengers to work in the calendar reformation but he could no longer correspond to this request Brahe the greatest astronomer of the pre telescopic era tried one of his inventions to which he called subtle process And Clavius the greatest figure of Roman College the major centre of Catholic knowledge in those times classified him as a supreme mathematician genius Pedro Nunes studied in Lisbon and Salamanca where he met Guiomar de Aires a Castilian Christian whom he married and from whom he had six children After obtaining his graduation he was hired as a lecturer by the University of Lisbon where he completed his Ph D in Medicine In possession of this academic degree obtained in the only scientific area in which it was available at the time Nunes could continue his mathematic investigations enjoying a comfortable position He was still young when his genius was noticed in the Court By decision of the king D João III he was preceptor of the princes D Luís and D Henrique teaching them Logic Philosophy Geometry and Mathematics He was 27 years old when he was appointed as Royal Cosmographer a position of great prestige in the country Two decades later he was appointed Royal Major Cosmographer In order to accomplish his obligations as cosmographer and teacher of the princes Pedro Nunes renounced to his academic position He was again appointed as a teacher after the transference of the University to Coimbra in 1537 and he remained in this city for the rest of his life He had his jubilee in 1562 and died in Coimbra in 1578 He was frequently called to Lisbon to advice and to examine the pilots to help making the cartography of recently
