"Lullaby, oh lullaby
this child to those who do?
I'll give it to the Befana
What keeps him I'll give it a week
black man that keeps a
whole year I'll give it the white man
What keeps him until he is tired
I'll give it to the Wise Elf
What makes the perfect man! " em>
This was the rhyme that my grandmother always told me as a child first I go to sleep =) rhyme that has its roots in folklore and popular presence in his fantastic and also mentions the black man, a character a bit 'out of fashion: we have many other monsters that populate and depopulate the television, entertainment, politics without going to need to bother this poor creature ... A far more mysterious presence hovered in the science of the early twentieth century, a myriad of brain shocker .. The black body! The black body is a theoretical concept which sees an ideal system to absorb all the radiation that hit and radiate with a wavelength inversely proportional to temperature. Simply put, "an incandescent." Try imagine a metal bar, warming we see the bar to take different colors: first dull red, then bright red, then white. It is precisely at this time that occurs the "ultraviolet catastrophe" in the gradual shift of the spectrum of electromagnetic radiation to the ultraviolet rays ... STOP! The laws of classical physics do not work anymore! Suddenly wavelength and temperature are no longer inversely proportional! How do we reconcile with the classical theory? To deal with the black body could only be a German doc, mustachioed man and all of a piece, a scientist called in the chronicles of the time "upright" and which was certainly not down this exception: he became a revolutionary against his will "as stated in the famous definition of Emilio Segrè. We are talking about Max Planck. It was a struggle with no holds barred-i-ever accounts could not be reconciled, which ended in 1900, the same year that another Central European, Sigmund Freud published the Interpretation of Dreams ravaging Europe, Planck introduced the "How! ". Planck's hypothesis states that electromagnetic radiation emitted by black body was caused by the movement of atoms which he called "oscillators": each of these oscillators has a key sequence that can assume only certain discrete values \u200b\u200band energy according to a proportionality constant called Planck in his honor. Well, this idea of \u200b\u200bquantized energy by introducing a "package" we can infer that a spectrum of light is emitted with a maximum intensity at a certain wavelength and intensity should not necessarily be higher closer to the threshold of radiation, after a certain value "maximum" then wavelength and intensity may well decrease both. So Planck was the "father" of the quantum. Planck writes: "Introducing what was an act of desperation. I had already fought for six years with the problem of black body. I knew the problem was fundamental and I knew the law, a theoretical explanation had to be at any cost ... My futile attempts to reconcile in some way with the elementary classical theory continued for many years and cost me much effort, it was almost a personal tragedy but animated by the relentless pursuit of Truth. " In the words of the current advertising of Bosch appliances, "he was a German!":-D
At this point, any person (if he has not stopped reading since the first 'bored with the topic), I would stop saying, "Excuse me, but I who cares of this black body radiation? I do not change your life! Ecchilevviva, Planck could spend time with some nice Berlin and a few beers instead of thinking of this "personal tragedy" of the black? "To which I reply:" Oh, no, my dear! You're wrong! This discovery profoundly change your life and gives you the fundamental questions "
• Let's talk a moment the philosophical implications of quantum mechanics underlying the struggle Planck ... This was only the first step of a scientific revolution that became known as quantum mechanics (and given the length of the next time I will tell you, point by point, we can make a soap opera "Quantum" if you like it). I tell you that only one of the cornerstones of quantum mechanics is the Heisenberg Uncertainty Principle which states that it is impossible to determine simultaneously the position and logically and the momentum of a single particle. You understand .. crumble the foundations of Western thought .. The principle of causality: "the present state of the universe as a result of its status as the front and because of its future state." We are accustomed to think of it this way .. There is natural .. but could be wrong! And if the concept of causality and cause-effect relationship was just a human convention that he had no real place to be? Would admit that everything is in the hands of If, indeed chaos. Not only that, the school in Copenhagen starting from this principle states that in reality not only can we not know the world, but even it exists, and we can classify it solely for "phenomena" that is, the set of things and processes with which we observe . So the world is "our will and representation", so there. Planck objected strongly to this interpretation be silenced as "a special case of the deep cultural relativism and the general pessimism that clouds these days." Planck said that there is definitely a factor in the origin of any business purely personal knowledge: it becomes subjectivism, however, because forces the scientist to seek settlement in the varieties and invariants of the real. Certainly, the approach of the person is essential in the cognitive process of reality, knowledge is an event that affects you deeply and will involve not only your brain and the ion current that can receive: the person is deeply involved in this dynamic. But if we deny the existence and the existence of real, then have no consistency even the book we are reading or the girl we like. We have to postulate that the "givenness"-as would the great Edmund Husserl, there is really a result of being able to say much sense: the givenness, "the reality that gives you gives "and that enters into a relationship with the absolute value of the centrality of Personacon its gradient of freedom that is constituted as a center of a surrounding world and entered the cognitive relationship with reality. Knowing is .... Beautiful!

Mamma mia .. an argument rather nice, heavy, but .... "When the going gets tough the tough start to play, my dear readers! Please tell me that I have not bored, I tried to have fun with a hint of irony =) "
Next time we'll talk about cats! More precisely, Schroedinger's cat! Until next time! : DDD
