Melacare Or Melalite Cream Is Good?

Equations "broken?

There days held be physical, and thus not material I mean, no, but having spent a few years to a natural science discipline that studies the properties of space, the time the matter and energy and their interactions . These are the days when I feel happy that we could be questions about how what we are, where we came from, where we are and what we are made ... Are the moments when I get excited remembering the magic of mathematics or checking the beauty of the universe.

Other times, however, usually more practical, everyday, in which would not have been trained in scientific thought ... Moments when Plato seems to me the number one enemy of modern happiness. What is what tortures me? What I dislike? ... Or ... What is it that leads me to disappointment?

The Incredible World of Ideas! Certainly, experts in philosophy, know this subject much better than me ... In fact, I intend only to outline the "torturing" Platonic theory: The world of ideas or intelligible world makes a clear division between the physical world, material, changing and imperfect, and one composed of ideas or impressions of these objects, immutable. This second world is considered by the author as perfection, close to the greatest virtue, goodness, the idea from which objects are constructed physicists who are merely imperfect copies of these impressions.

Physicists, like many other scientists, we also have our own conception of the World of Ideas. This world is full of equations, expressions and relationships. It is the world of mathematical models. The models are simplifications that make a complex and intractable object into something simpler and explore, through scientific methods. The models are very useful and have been very useful to assist humanity in understanding the world. Although not know if they are the only path to understanding. Still, it is true that if we were to have into account all the endless details of each object of study, I would never even to enunciate ... But of course, one thing is to simplify and get the other comical situations as described by the first story which is explained in Fundamentals of Physics to get to the University:

There once was a cow that gave little milk and its owner decided to call several scientists to help him find a solution.
biologist replied
- "No problem, do a genetic study of the cow and their parents ..."
To which the chemist said
- "Well, maybe we could analyze the feed and water which is fed ..."
When the physicist said:
_ "Look, it's better for us to imagine a spherical cow of radius leg and constant density in a gravitational field."

can not help, just watching the cows unsteady as open systems that exchange matter and energy with the outside ... Obviously, I'm exaggerating!, But if it is true that simplify, model, and above all, becoming the world intelligible, creating ideal models, just leading a kind of idealism, Platonism and "disappointed" if you are not aware of process intrinsic to the method.

For example ... want to study the air. A mixture consisting mainly of oxygen and nitrogen in gas state. We can focus on any of the two components and go find one of our laws and equations ... The ideal gas law!

The law ideal gas equation of state is the ideal gas, a gas composed hypothetical point particles, without attraction or repulsion between them and whose collisions are perfectly elastic (retain the momentum and kinetic energy) . They are wonderful ideal gas, but are nonexistent! The gases are gases that surround us real ... And agree that there are some, like the monatomic gases, which at low pressure and high temperature, have a lot of behavior that approaches that of an ideal gas ... but ... authorities remain platonic, abstract entities, fictitious entities ... authorities disappointing ...

Perhaps, this is a hypothetical problem and that is myself building my own "ideal conflict on idealism" ... I want to make a call to physical Mandarin s. .. And .... also physicists Is there in you asymptotic trend towards the construction of utopias (which Waslala , a great novel Gioconda Belli, by the way) and never reached expectations?

Otherwise, if no one involved in my conflict, would package revise my assumptions and my theories ... but ... if one, only one of you help me in this ongoing creation of " ideal worlds" and " real frustrations," he would give, from today, a spherical cow, a human infinite cylindrical thread, which led for years, in my luggage.

If you want to read more stories like that of the cow, or extend the reading on the model, the prejudice, the scientific method, among others, has just published Claudi Mans an interesting book with a very suggestive title: Spherical Cow. Health

all and I was not discouraged ... To evil is nuanced and crannies!

four museums, four different stories


This is still a very museum summer for me ... A very special summer.

Just under a year, I started this blog with a post in which he spoke of the temporary exhibition devoted to the hominids outlined in the Staatliches Museum für Naturkunde Karlsruhe . That was the August 4, 2008. This summer, in my thirtieth anniversary, 4 July 2009, I crossed the Atlantic and go to visit some museums of science and technology of the West Coast.


I spent ten wonderful days touring the California coast between Point Reyes and Morro Bay. It's been an incredible journey in which I could enjoy nature in its purest form. If you saw the way to Point Reyes deer, cows and an old lighthouse built in the late s. XIX.


During our descent along the Big Sur redwoods towards Morro Bay we saw our way through the Redwoods.

and seals, walruses, otters and squirrels in Piedras Blancas. It was very exciting!


But it was not just my birthday and nature in its wildest only actors in this journey. Centers such like the Exploratorium , the Tech Museum , the Monterey Aquarium the California Academy of Science the San Francisco Museum of Modern Art or the Japanese Tea Garden in San Francisco were also leading my fleeting visits California getaway.

Each of these Museum breathes and beats and even differently from the four science museums visited, there were none to repeat the same story.

The same July 4, excited not only by celebrating American independence, but also my entry in her thirties, visited, the most anticipated of the museums ... the father of the interactive, the nest of creativity. Yes, with the image of the Golden Gate Bridge even on my retina ... could see the logo Exploratorium. The excitement was not small ... And I have to say ... That the experience was not at all disappointed! Between those four walls and large open space that is agglutinated thousands response actions that gave thousands of questions and generated even more questions. A giant concave mirror us back a mirror image and the focal point between the mirror and the observer. The laws of physics, were mixed with perception experiments, Biology, Psychology, Art or Engineering ... The shop was also forced stop Exploratorium ... it bought the odd memory, scientific juguetillos and several books. On my desk waiting for me incredibly wonderful Something Happens, Frank Oppenheimer and the World He Made Up KC Cole and Exploratopia more than 400 experiments for curious minds developed by the Exploratorium own .

The next visit was to Monterey Aquarium. Personally, I feel a certain attraction to the world ocean, the water and the deep sea. I imagine that, as stated in the aquarium itself, the sea is the closest we get to be from another world . Still, I want to stress that the Monterey Aquarium is something special. Their motto is "explore, discover, act." In it, discuss the beauty, scientific knowledge and ecological responsibility. It consists of a beautiful and diverse museography adapted for different audiences. There are rooms designed for children, including for so small they only play with shapes, sounds and some concept. The content is multiple interactives are well acclimated, different ecosystems and pedagogically breed jellyfish exhibit is the work of living art world's most beautiful. As hives and as fascinating ... You could spend hours watching these creatures ...

Up the road we saw central vacuum systems for oil ... Finally we come to San Jose. Our stop in this city was destined to get in touch with the Tech Museum staff , who treated us with great kindness. The Tech Museum is a different museum, where the technology starts to be creative! Long ago, the Museums are seen as places that speak of the past, but do not forget that back in the day, the Universal Exhibition was a great revolution in the exhibition. Showing contemporary science, technology and gadgets of today and tomorrow. We could say that Tech continues that step forward.

And we go back to San Francisco ... the trip is over and we still have a lot to see and taste nostalgic because we know that although there have been only ten days, never forget California. Back in the city , visited the California Academy of Science . A newly renovated museum offers visitors a pecking among the different specialties with fresh formats and youth as open day with cocktails late scientific and not so scientific. Perhaps the part I would like to point out in the planetarium. An immense dome with six projectors ready to show the mysteries of the sky. And finally, an innovative green roof to visitors for all with telescopes pointing to the sun, our sun


As you can see there has been a dull moment ... rather it has been an experience that had long wished some more months ...



Once back, I attended the course Science, Technology Industrial Heritage i: i Museïtzar Store offered by the University of Barcelona. Ten teachers, including Jorge Wagensberg, Xavier Roig or Isabel Fuentes we have been approaching the concept of museum, interactive, industrial heritage ... We have explained their individual cases ... In particular I would like to congratulate Turull Emi, director of Museu Agbar de les Aigues , for its exciting exhibition and bright ideas, activities and proposals of the center. But despite 20 hours of lectures ... I have the feeling in the throat ... nothing is like experiencing the adventure yourself in a museum. Smell, touch, hear, see and judge the great pioneers and is really inspiring. If someone has the opportunity to travel to California, do not miss these four museums, with their paths stories.

In Citilab are thinking about starting a new exhibition road, but the philosophy of the center ... have to make a big dip so that we could reinvent a new concept of participatory technology exhibitions. We keep you informed ...
