More than 40 collaborations (for the time being). I hope not to have forgotten none, and if I did it, warn me that I add it immediately.
For the prompt thing, they are divided in two groups, which will be published in simultaneous, and to arrange them better, I classified them under different categories. I believe that every post sent to the Carnival deserves that we take certain time with him, and believe that this way it is facilitated to do a break to continue later.
I made a brief comment of each one, and in many cases I have added links, but I preferred to leave them like comment in the corresponding blogs, and not turn the attention away from here towards third.
Let's start with the parade of that I titled Education and Personal details.
Education
Mathematics, atoms, hair and snots: Sergio brings to us the problems of Fermi, which teach us to do rapid estimations to attack insoluble problems in appearance. The hardware that they use is simple: to extrapolate from reasonable samples, to annotate the quantities between magnitude orders. If one takes it seriously, and it attacks a problem of investigation, the following step, to deduce simple formulae like the laws of Kepler, the period of the pendulum or the law of universal gravitation, it is the analysis adimensional (also it serves to determine the time of cooking of a chicken). And finally, when it has involved functions, the Nirvana: linealizar (or Taylor of order two, never more of that). Since they see, hardware that fit in the portfolio of the lady or the pocket of the gentleman, do not allow to catch them without them, and they be transmitted to his pupils.
You grasp in the sleeve in class of Mathematics: Juan Luis indicates a set of examples to surprise the pupils. For me, the topic of the big numbers is one of the most interesting, for his connection with different fields (algorithms complexity, without going further). My favorite example, to introduce the exponential growth, there are the chains of mail if each one forwards them to ten contacts.
You remain in a square, Construction of an Omnipoliedro with PVC and cañitas of refreshment and Antimagic square. Intense level: Joaquín brings games and constructions over for the classroom. I recognize it: I have zero intuition / handling of the geometry of R3, and except a bucket (thanks to my experience with dice), any other object I it must manipulate a little bit length before 'seeing it'. He would have to practise a little bit with the pvc polyhedrons...
The Fermat room: Manu does a criticism of this movie, and leaves to us the puzzles that appear in her.
A big problem masked by the apparent simplicity of a story: The Beautiful Sleeping one: Manoli leaves also a problem to us, but I believe that his reflections are more important on the education.
We play with Sidon and Golomb: Antonio brings another problem over to explore in the classrooms, with guide of targets, instructions, table in excel, etc.
Carnival of Mathematics II (III Centenary of the Fair of Albacete): Juan brings to us an elementary problem, based on the error of adding two times the same. [On the invitation that it does: it would be loved to the Fair of Albacete! let's arrange the matter of the passages and the accommodation, and there I go ;)]
Method ac for factorizar trinomios on Z Carlos brings a method for factorizar trinomios in Z.
The Simpson: the girls want only to add up Eva presents the chapter of the Simpson (in answer to the sayings of Summer, I am thinking about remembering), and adds a sheet questionnaire so that the pupils should complete.
Personal details
Sixth Sense: Tito leaves a Darwin phrase to us, on the sixth sense that the mathematicians seem to have. It is worth while following that the link that Francis leaves in the comments and reading in more should detail the autobiography.
The formula of Of Moivre: Jesus Soto brings to us the relation between the formula of Euler and that Of Moivre (that is previous). In fact, Roger Cotes got them into the way, finding the formula that today we call of Euler. I can only repeat something on that I commented one day: thousands of things it did Euler, which take foreign names; and the few ones that take his name, it them did other before him!
Sofía Kovalevskaya y Cauchy: E. Gracián contributes with another two posts, the biographies of two mathematicians who also join in the name of the theorem of existence for equations basic in partial derivatives.
The famous number Pi: Ann Maria elects this number as an axis of a series of posts, worth topic for a Carnival that closes 14/3. I keep on believing, equally, that we-hispanoamérica - he should celebrate it on July 22.
The order of the factors sometimes alters the product: Migui gets with the not conmutatividad of the operations, and quotes examples of those that it is worth while: kitchen recipes, to turn a bucket Rubik, to cross a street with semaphore, and many others.
To study mathematics: and why not?: Javier reflects on the mathematics careers. His motivation is the fall of the registration. For these sides also a mathematician is difficult to find without work (still the advanced pupils usually obtain something, although it usually enter a cycle that prevents them from being received because they have no time to dedicate him to the career, and it is not also so many urgency for be receiving since they already have work). Also there is very true the topic of the facility of the calculations, or the numbers handling, although when I say to what I devote myself, I do not have the same problem (as they can see in the first link of my 'non-participation' in the carnival...) . Nevertheless, the final point on Later what do I do? it depends too much of individual capacities that do not belong to the career (capacity of synthesis, flexibility in the reasoning, modeling of different situations, capacity of planning). In fact, having them, it is still difficult to mention an employment where I reached with this; that's why the objections of some comments are very worthy of attention. Nevertheless, in this that I add, am not giving an account not to study mathematics, and coincide with the general idea that raises the same title of the post: to study mathematics: and why not?
Crisis times, qualifications with future. Do matemátic (and II): Luis supports Javier's post.
The Problem of the First Digit: Beleragor speaks to us about the distribution of the first digit of the natural numbers. He did not know that Gauss was surmising the Benford law, but it would not be strange in anybody that it was manipulating logarithmic stage often (that is, in the fund, what hides behind this law).
Synthetic thought: Antonio reflects on the artificial intelligence and the Test of Turing. Whenever I see this topic, I wonder if Turing will have imagined the current situation, where to leave a comment in a blog, to register in a place, and so many other cases, we must demonstrate that we are not a machine route a captcha. A good source, without many mathematics, for this topic, is the book The Eye of the Mind, of Dennett and Hofstadter.
Teaching to Think: Silvia brings to us an acquaintance pseudo history of the science.
Famous appointments on Pi Eva he adds appointments on pi of different epochs.
Being about the border blogosférica: Edition Day Pi: Javier brings to us, between other things, an excellent article of Bob Palais. The truth, even the perimeter suits (using I remove instead of the diameter). The truth, the only formula that would turn out to be harmed, is the one that says to us that the gravity is pi to the square... but there are small those who know it, so it would not be a big disadvantage!
(in fact, the post that it was going to prepare was treating exactly about that: g=pi2... it will stay for another opportunity!)
My not participation in the 2nd Mathematical Carnival: For time questions, could not write a decent post, and I preferred linkear two old men posts to which I have certain affection to them.
Triple Teselación in Masjid Negara: I close the list with Rafael, next host of the Carnival, with a post that does not deserve words, but to enjoy the images.
