Today, in many places of the world, Monday of Carnival is celebrated, the most important day of the whole holiday. And in the mathematical world and, in particular, in the blogosfera of Hispanic speech, today it is the First Edition of the Carnival of Mathematics.
During the whole last week, earnings related somehow to the Mathematics have been published, in order to spread a little more the kind side of the same ones. More than 40 blogs they have taken part with more than 60 articles that right now I happen to review for subject-matter.
Some authors have decided to speak about Mathematics from the literature. This way, for example, from DesEquiLibros we meet a curious titled appetizer The Wise person of Palace in which they tell us a famous problem of share-outs of heredities. On the other hand, in Mathematics next to us they have preferred to tell us the History of Pi, the irrational pirate. Finally, our good friend @Zifra, in his Swap 3,14, has brought to us a compilation of his famous mathematical Minifictions in less than 140 characters.
Also we could have enjoyed all this week solving problems and puzzles. This way, from The Logical Mole they raise a Problem to us on Probabilities; in The Mathematicians they are not the serious people we meet a curious problem of areas and beards; from Blog Zona Press they tell us the pleasures of solving a puzzle the not only one, but two times. From interactive Mathematics and manipulativas, they offer us several problems: you add up in a triangle, add up in a square and a magic anti-square. We even have had participants very related to the cycling as there are a Bike for Barcelona with a problem of estimation and Plegaleando for Seville with his equations with words. Special mention I want to do for, probably, the youngest child of all of us who, from his blog Reprint Gauss II, tells us a problem on Five pirates, many coconuts and a monkey. And finally, and a little for the hair, it has brought in the puzzle on numerical series proposed from Life and Mathematics.
Other one of the things with which, during this week, they have delighted us is with photos and mathematical images. Of it they have taken charge in Mathematics next to us, where from they have presented a parabolic Clock, and the blog to us what I see in Saragossa, which diverse photos have taught us on Parallel bars, Stars, habitable Geometries, Spirals and geometric Fronts.
Also the Geometry has capacity in this carnival. From The Science for all they teach us to construct tables that never limp, while in Mathematical Notes they teach us to solve a problem on Farms and deposits. On the other hand, in Pandora’s Memories they have spoken to us on how using the Mathematics to adorn by means of homogeneous mosaics. In The Rafalillo world they give form to the credit cards, while in Physics in the Science fiction they have brought to us some squares and rectangles and more squares. From dynamic Geometry they bring to us Jansen’s Mechanism and in The Song of Malapata they teach us what a Diagram of Voronoi is and explain it to us to conscience. Finally, I want to emphasize another two university teachers of mathematics who have brought to us more advanced earnings. In particular, Juan de Mairena speaks to us about Three theorems on the water and his absence of form and Francis (th) And mule news he has made use of the carnival to speak to us about exotic Spheres and the unvariant of Arf-Kervaire from the point of view topológico and geometrically.
But: what would be of the mathematics, and of this carnival, without the numbers? Since of being right in presents several blogs have taken charge. In Betacontinua they have introduced us, with holder pardójico including, The Simple Complex numbers. In Numbers and Spreadsheet they speak about Frobenius and the MacNuggets, something not suitable for hungry, skylight. In Cinders in the trébede they teach us how the Muslims were multiplying, while in texnologia how there was the Chinese multiplication (with translation incluída). From Matgala, they present to us how to describe to the number Pi with sums and infinite products (with his original version in Catalan), in Gaussianos they speak to us about the numbers of Catalan, but not, it has not anything in common with the language, but with a called mathematician like that. On the other hand, from Mates and + they teach us what they have to do Homer Simpson y Fermat. And finally from Curiosities and thoughts they bring to us some curiosities of the numbers.
From Blog de Sangakoo they have done this week a monographic one on the infinite in which they have told us some paradoxes of the infinite; also they wonder if the real straight line is real to finish with the famous problem of the Bridges of Königsberg.
In some blogs they have offered us appointments and thoughts to reflect. In The adventure of the Mathematics a child asks his father why we like the mathematics; from DesEquiLIBROS they wonder for the alternative to the Mathematics absence and about the Swap 3,14 make to think a little our mathematical companions. In The Song of Malapata they remind to us that there is no place for ugly mathematics, while in Trip to Ítaca with Manoli they wonder if more logicians are the mathematicians. To stop reflecting, in science in the XXIst they believe that that almost sure that the sun will go out tomorrow, but well, that would be that demostralo mathematically.
There are those who have decided to do articles about opinion contrasfondo mathematician, as the case of the blog is Mathematical: 1,1,2,3,5,8,13… where it is said to us that in crisis times, to be matemátic is a future profession. Also like opinion, I have catalogued the article about The mathematical Small cave where the mathematics appear before us like amienemigas of the man.
From the blog Zurditorium, they speak to us about the mathematicians departing from the sets, while in the same blog also we have written about sets theory and, in particular, of how measuring sets of real numbers.
But not everything in mathematics is abstract. There are those who, departing from the relation that exists between the mathematics and the origami, offer to do mathematics to us with the hands. This way, in interactive Mathematics and manipulativas they teach us to construct flowers with geometric motives for San Valentín, in Mathematics next to us we will learn to do a good hat to ourselves for the carnival. Although if we want something rapid, the best thing is that you pass for Pi-Bugs so that we learn to construct instantaneous dodecahedrons.
Also there is the one who recommends to us some book. In particular, from Bibliotranstornados they make the most of the opportunity to show us a good compilation of ancient mathematical books. And our good friend Migui teaches us The big book of the random numbers, article that has come to front in Wiggle me.
But: what would be of this life without the music? Since in the carnival it was not missing either. And of that the gravity boys have entrusted themselves Zero who sing to us that 2+2=5, and the blog Looking Names, that speaks to us about the parallelisms and convergences of the mathematics and the Jazz.
The games and, since we are, the Games theory (that is something very different, but that in this entry they are going to go of the hand) has been made present in several blogs. From The Machine of Turing, they make use of a chapter of the series House to speak to us about Instant Karma: Dr House, Roy Randall and the deceit of the player, while in The Science for all they have chosen a passage of The Revenge of Don Mendo to tell us something on half after seven. Finally, in the Blog of Mathematics and TIC s they have spent the week to themselves playing the English recluse.
Next, I present to you a series of articles in which they teach us that, sometimes, the Mathematics we are them in the most unsuspected places. For example, from Kitchen and Mathematics they have managed to take the measures to him to a pancake, while in the Swap 3,14 of Zifra have found many mathematical postal stamps. In Wis Physics they have told us some mathematical milestones of the antiquity (article that also has been carried in Wiggle me), as it is the calculation of the distance of the Earth to the Moon. And there this time is where they have been in charge to The Unyielding Village to realize field work and to be able to tell us that The Moon is the biggest homage to the Mathematicians.
But let’s leave the Moon and let’s go to something more mundane. The carnival without humor would not be the same, and that itself (cost the redundancy) we have thought some. So from The Song of Malapata they do to us a compilation of vignettes of mathematical humor, while in
