week Vocational
During the last week of August this year, vocation week was held in Little College. We saw several shows and talks by children and professionals involved in the technology. professionals, toddler as sales. In my opinion it was pretty good (hope so), because the work there was reflected by students and teachers was too much.
In just one example ... here are some pictures of what realizado.Fijense on some faces ... (lol)

| not the first time we visited from this blog to prime numbers. It's strange fascination with a fairly restless mind. After a seemingly anodyne definition (a prime number is one that can only be divided by itself and by unity, giving an integer result for that division) hide many surprises. For starters, the size of the set of prime numbers, which showed at the time by five different procedures was infinite. Although after five shows anyone can be no doubt of the infinity of primes, there are still many unknowns about the same. To First, increasingly appear to be less common: after a start that nearly all the odd numbers are prime (1,3,5,7), quickly becoming scarce. However, we are faced twin primes (odd row, both cousins) in the whole N. |
A Book especially for a special place.
There are many types of books, but as Carl Sagan remembered, a human life is too short to read an infinitesimal fraction of what is published and you have to choose. The first classification, where there is obvious is that which separates what is published in two parts: what interests me and what does not interest me. So do not make value judgments about the works. Within
what interests me, a very personal but clear separation is: what is affordable for me and what is not. Here we enter a very personal terrain in which the availability of time, my own preparation, my priorities and my economy is a lot to say. Then choose what interests me and is accessible to me.
In this clade there are books I can read anywhere and books for those who need some external trappings: there are books that I can only read under a reading lamp, wrapped in smoke snuff and in absolute silence, even with paper and pen nearby to take notes while others are summer reading lounger under an umbrella (not direct sunlight, please.)
At this point the personnel classification key books that show, no longer becomes dichotomous and multivariate analysis. I have books, stationery, books to read in bed, recliner books, tavern and public transport. But I want to talk about a type of books I have reserved for one of my favorite places, the sancta sanctorum of the reader: the bathroom.
In my private bookish taxonomy to classify a book as a bathroom book saying much about the issue concerned, and all good: a book must be agile; of short chapters to read an entire rational time you spend in that place should be interesting and should not fit exactly into any of the above classifications. This last point is important, because I'm very influenced by my reading of biology and has always fascinated me in particular taxonomy and human effort to classify biospheric diversity in clades nested, so that a clade but never owned one and only one of higher clades. So not for me books to read in any other place, and therefore despite the seemingly eschatological issue this taxon is of absolute excellence in what I'm concerned. Few books deserve such status.
So, let's talk about books to read in the bathroom. Books to take, taste and enjoy in a short space of time. Books whose chapters are gems that deserve the rest and solitude of these intimate moments and nontransferable.
My current book in these circumstances is "Ideas for the impure imagination", 53 reflections on his own substance, Jorge Wagensberg.
The author was born in Barcelona in 1948, has a degree and PhD in Physics from the University of Barcelona and Professor of Theory of Irreversible Processes in the School of Physics at the university, where he heads a research group in biophysics. Is author of numerous scientific papers published in international journals and an extensive scientific work of spreading to other domains of culture. In 1980 he published the book We and science (Bosch Editor) and 1985 ideas about the complexity of the world (Tusquets Editores). In 1983 creates the collection of scientific thought "Metatemas" also Tusquets, and since 1991 he is director of the Museum of Science Foundation "la Caixa". After this cluster
guarantees you do not take this book without expecting anything of much interest, so that the a priori requirement is high. Fifty-three reflections are 276 pages that each reflection is cortita in size and very easy to read, but each is full of beautiful deep implications and reflections that can aborad post. They show the scientist as being an avid seeker of reflection and inspiration unrepentant any apartentemente trivial daily occurrence.
A book in very exceptional interest, worthy of an author who has long demonstrated its power to disclose to its size while a scientist, an author who titled one of his works with one of the most amazing and wonderful titles that 've ever seen, with a phrase worthy of the best Zen koan: "If nature is the answer, what was the question?" (Stock Metatemas, No. 75; Tusquets editores).

Zoo numbering bases
Once again, our collaborator Jorge Alonso provides us with an article full of interest. In this case involves numbering systems, an extrapolation to the unusual and coherecia meaningful. I leave with him enjoy it.
imagine that there is a zoo where we can contemplate the base positional system of numeration. Let's walk through it.
Just start
specimens are known, the decimal, the binary and hexadecimal:
Following are the systems based on a negative basis, thanks to which it can represent integers without having to enter your sign. Let the base -2:
Notice how the negative integers have an even number of digits, and the whole positive odd.
continue, and we find bases that are not integers. To begin we
rational basis 1 / 10, in which to convert to decimal invert the digits:
is followed by the irrational base (10) ^ 1 / 2, in which the numbers are the same as in base 10, but adding zeros between its digits:
following are bases whose digits are not all integers can be digits representing rational numbers irrational, complex ... We
the end of our walk, and taking a look back, we just remember that all these systems can be mixed together ...
