Perhaps someone will have realized that the last time the scientific news, for a few others, are becoming somewhat unusual. I read in the November issue of "The Science" which was found an example of a magnetic monopole, a phenomenon previously thought impossible. Also in this issue promises to be a violation of the law of symmetry, one of the super-light physics considered inviolable.
All this was preceded by a conference held in Genoa on October 28 by Lee Smolin, in which the existence of multiple universes, which he theorized, was denied in favor of affirming that a single universe. In light of these changes can we say that we are faced with a new Copernican revolution? Meanwhile, let's analyze the best explanation of the different findings mentioned above.
The magnetic monopole
Ever wonder what happens if you "cut" a magnet in two? The answer so far physics gave to this question was that it would be achieved through two smaller magnets having both poles, north and south, as the original magnet. Several experiments prove this theory, experiments with various materials and temperature normal. Nobody had even thought about the "spin ice, spin ice. We are talking about material with similar structure to ice, whose ions rotate with a given orientation. Ions are electrically charged particles possessing positive or negative that make up the material. Are atoms that has been ripped an electron, the case of positive charge, or who have torn their an electron to other atoms, if not. The ions are organized in crystalline structures, such as square lattices.
After stabilization of the material the magnetic field, physicists have disrupted again to create the possibility of formation of magnetic monopoles e. .. Tadah! A situation similar to that of the monopole was found really! It would seem a simple thing, but in reality the process is not so obvious. Meanwhile, the material must be brought to temperatures close to absolute zero, -273 ° C, then the magnetic field must be disrupted trane another magnetic field, strong enough to change the way you want first. With
field means the disturbance space due to an object located in it. For example, the gravitational field is due to the presence in the space of a body with non-zero mass. To have an image of a field, one can imagine a sheet stretched with a soccer ball placed on it. The fabric will yield the location of the ball and form a depression that will affect other items on the sheet. For example if I put a marble in newly generated this will move the football, because it is subject to the forces generated by the field, the depression of the sheet in a nutshell. The ball, however, creates in turn a field on the sheet, but much weaker than that of the ball, then do not realize it. If we put another ball on the sheet could significantly disrupt the field generated by the first ball. The concept behind the experiment is just that, generate a field strong enough to change the first in a meaningful way.
Besides having to find the right way to change the field, monitoring the success of the experiment is rather difficult, because the distance between the two poles is of the order of millionths of a meter. However, despite these findings, researchers are questioning whether the real magnetic monopoles, because it is not a single particle with magnetic charge, the real monopoly, but of two separate poles. The phenomenon was never found, and this makes an interesting discovery. Appearance updates on the subject.
The law of symmetry
By law of symmetry is defined in physics, the law according to which an experiment conducted under the same conditions than in another experiment should give the same result regardless of the place and time in which it runs. In practice, if I drop a rock from a cliff 100 meters high, with no wind, the time it takes to get the stone to the ground and the crash site will be the same. That I drop the stone in Japan or in America in 2012 or 3005, not in any way affect my result. Some physicists, however, are skeptical and say they do not agree with this statement. This Their idea is supported by an experiment conducted in Japan, the result does not conform precisely to the predictions based on symmetry.
The term symmetry in physics is intended more as invariance, symmetry and as a literal. So despite the initial data were unchanged compared to an experiment already conducted, the result was different. With this "discovery" of the physical world is facing new questions about the super-light, considered inviolable. The theory suggests that a unification of physical laws into a single universal law could be reviewed. If you actually prove to be false, many theories should be reinterpreted, much work would be unnecessary. It opened, however, new doors to a deeper understanding of reality.
The Multiverse
As mentioned above in Genoa held a conference of great importance. Lee Smolin, a theoretical physicist at New York American, born 1955, one of the founding fathers of modern quantum physics, denies the existence of parallel worlds, a multiverse, which he theorized. The grounds are not scientific, but are purely philosophical. Nevertheless, it is important to consider the issue as a turning point.
The four points raised during the conference are:
"There is only one universe. No others exist, or there is something that is isomorphic to it." This
statement refers particularly to the theory of sets. In fact there is another set that can perfectly reproduce the set of departure if not all the same. So the universe can be "replicated" only by himself => there is only one universe.
"All that is real is it in a moment, that is (itself) a succession of moments. All that is true it is in the present moment."
theory of something that exists outside of time is denied, all that exists is found in time, even time itself (as it actually exists and not a product of the human mind).
"All that is true at a time is a process change-to bring to the next or future moments. Whatever is true is one aspect of this process in a process involving or causing future moments. "
If something else were to exist without cause, then that something has to disappear in the next moment. If something persists, then it must lead to something ' another, is part of a process.
"Mathematics is a derivative of the experience that serves as a generalization of regularity observed, when they are removed and special time."
Mathematics is not a law on which the world, but is derived from experience on the lawfulness of which is based on. These words of Professor. Smolin could Sebri natural and logical, despite that many mathematicians tend to forget (forgive the "dig").
Unfortunately, since you do not know enough on the subject will not try to forward them over the matter. For those interested in the topic, Smolin has published three books, as I understand it, in which issues such as string theory and quantum gravity are explained clearly to all. titles are "The Life of the Cosmos", "Three Roads to Quantum Gravity" and "The Trouble with Physics."
The bird terrorist
On November 8 the Republic could read an article about CERN in Geneva, in which he informed the resumption of activities after the repair of the generator LHC-B, one of three feeding structure. Cause of failure was the meal of a bird, a piece of bread. The traces found on the site they give the test, even if you managed to find just the bread. The fate of the bird is still uncertain ...
What may seem like a story from nothing in reality could confirm a theory recently developed to explain the different "bottles" LHC (Large Hadron Collider). It is believed that nature is sabotaging the experiment does not allow us to discover a particle known as the "God". Again sounds like science fiction, but who if not better than an anonymous sparrow or a pigeon camouflaged in gray Swiss could carry out an attack like that? Obviously I'm joking, I do not think that nature can weave a plot like that, haha \u200b\u200b... or does it?
For the moment at CERN is everything, if I get lucky, around March or April I should be able to visit the property in person, in that case will obviously now an article on Pot-pourri.
Well, that article to say that still do not know where it will end the matter ... However I have found several interesting discoveries and I felt good communicate. I hope it was interesting even for those who have read this article.
The next article will be a book written by Einstein and Infeld, in which we try to put the physics concepts in simple and understood at all.
