Deutsches Elektronen-Synchrotron DESY

DESY ist eines der weltweit führenden Beschleunigerzentren. An den Standorten in Hamburg und Zeuthen bei Berlin werden große Teilchenbeschleuniger entwickelt, gebaut und betrieben, um damit die Struktur der Materie zu erforschen. Das breit gefächerte, international ausgerichtete Forschungsspektrum beruht auf drei Schwerpunkten: Entwicklung, Bau und Betrieb von Beschleunigern, Forschung mit Photonen sowie Teilchen- und Astroteilchenphysik. www.desy.de

Vor 100 Jahren, im Jahr 1912, hat Max von Laue die Beugung von Röntgenstrahlung an Kristallen entdeckt und damit das Tor zur Erforschung des Nanokosmos aufgestoßen. Die sogenannte Röntgenstrukturanalyse hat sich heute zu einem der wichtigsten Werkzeuge in der Nano- und Bioforschung entwickelt. Sie erlaubt, die molekulare und atomare Struktur der verschiedensten Materialien zu entschlüsseln, und liefert unter anderem Informationen für die Entwicklung effizienterer Solarzellen, besserer Datenspeicher und neuer Arzneimittel. Der interdisziplinäre Nano-Bio-Forschungscampus, der rund um DESYs Röntgenlichtquelle PETRA III entsteht, führt von Laues Forschung ins 21. Jahrhundert. Zu Ehren des Physikpioniers hat DESY die große PETRA III-Eperimentierhalle nach Max von Laue benannt.

DESY: ГРАВИТАЦИЯ. что это такое на самом деле.(а ларчик просто открывался)

To facilitate the understanding of what I want you to hear, first: Forget everything you thought you knew about gravity! Second, do not wait any torsion fields or other casuistic theories, because that's all I have to tell you, these are the facts proven or refuted by mainstream science. With most of these facts, you will come across in the course of the study of physics. I also want to say that I'm just, I deduce the common denominator of all science has achieved in the description of gravity, since the time of Newton, and ending with the quantum theory, including some ideas of Einstein. First of all you need to understand the concept of "field", and to deal in all senses of the word. So, when we say phrases like: "electromagnetic field" or the "gravitational field", we mean that the body or charge created around energy shell of infinite radius. But I'm sorry! The energy conservation law forbids us to squander energy in this way, since according to him, the energy can change from one form to another and transferred from one body to another, and quantum theory rules out the existence of such entities, in the "field theory" Landau-Lifshitz, plain text is written that we can only partly be seen as a field, the energy of interaction between the bodies subject to the principle of superposition. This means that no field does not exist, no gravity or electromagnetic, and this fact has been postulated in the mid 20th century. But why is no one paid any attention to it, and it changes the whole thing seriously physics placing it on its head. At least because both Newton and Einstein were guided by the notion of the field name. Let's go back in the time of Newton. The problem is that at that time has not been studied nucleus of the atom, but for what was already the law of the pendant is open, do not you think it fair that Newton know about quantum theory and atomic charges, he would have conducted appropriate studies and their relation to gravity ? Especially as it was already obvious similarities in the manifestation of these forces. But nothing prevents us to do this with you right now. Let's imagine two protons and two electrons, as four individual particles, each located at the top of an imaginary tetrahedron, that is absolutely an equal distance from each other, at rest, with disabled charges. (Figure for readability is somewhat different from the tetrahedron, but we assume that the distances are equal) Is equal to the distance between the particles, taken in order to determine the vectors of Coulomb forces destroy the equilibrium during power charges. Now turn on the electricity, that is, the Coulomb force. As you can see in the picture between the particles, forces pull (green lines), and the repulsive force (red line), and we see a number of these forces, according to Coulomb's law, these forces are equal in value but have different vectors. The principle of superposition states: feedback on the particle number of external forces is the vector sum of these forces. That is: we can simply add these forces drawing a plus sign, minus sign repulsive, and divide by the number of particles, 2/4 that is, the amount of force with which each particle is attracted towards the center of an imaginary tetrahedron is equal to half of the Coulomb force acting between any two of the charges set forth herein. As for the vectors, then we can see that the repulsive moments pass exactly through the center of the shape formed by the charges, while attracting force as it is crimped around the shape and direct charges to the center. Please note: no gag on my part, everything is fine stems from school physics course. "But this is just the charges," you say where does gravity? And you will be absolutely right, but the thing is that the electromagnetic interaction has infinite range, and we can use, taking Lobachevsky, and take away our charges on the atoms, having received two full-atom of hydrogen, the only change how you see the distance between the charges, the structure and distribution of Coulomb forces remained the same. What does this mean? This means that two hydrogen atoms have attractive force to each other only due to Coulomb forces. Moreover we even brought value of this force is equal to half the force acting between any two charges on the predetermined distance. And this value is always positive! But let's see what happens if we have one of the hydrogen atoms will add another and form the body of the two hydrogen atoms on the one hand, and one on the other, how is it distributed Coulomb forces? If you notice, the resulting force of gravity acting between two bodies is proportional increase. Oh, really? That's a surprise! that is, m1 * m2 directly what that Newton's law is obtained, especially for the doubters say: This experience can make any number of hydrogen atoms in two bodies, and Newton's law will remain in force. And now calculate the Coulomb force with which the planet earth attracts the hydrogen atom: that is, we have the Coulomb force of attraction that acts between the two hydrogen atoms, multiplied by ten to fifty zeroes. That is the approximate number of protons of the planet earth. You understand that the total amount of these forces gives no laughing matter? Let's go over how to regard those forces which we have just seen? It is the most important thing is that I want you to hear, THESE FORCES OR POWER OF ATTRACTION, calculated by Newton's Laws! These are the forces that act on the AMOUNT of an imaginary spring balance between two bodies! That is calculated by Newton's law, the value of force is the sum of the Coulomb forces are precisely at the time of the acts or obstruction of the attraction of these forces. But the strength of the resulting reports another body during acceleration due to gravity, is the sum of edenichek the Coulomb force acting on an atom of hydrogen or its equivalent attracting body, that is not attracted to the whole mass of the other mass, and each attracted one single hydrogen atom, or its equivalent, the other mass. That's why Einstein was in the elevator and did not feel the acceleration, because we can not feel the pressure of a single hydrogen atom, especially when it happens to all of the charges are part of the human body. This leads to an interesting conclusion: it can be argued that instantly dispersed, each atom of the body to the speed of light in one direction, the man not only did not hurt, but it did not even feel it. The same occurs in the opposite direction by the principle of superposition. That is all the charges of the human body, according to the acceleration of each charge of the planet, with a force directly proportional to the lower fold of the masses. and Newton's Law, it perfectly describes: Gravitational constant F=(G * m1) / squR where F = force acting on the hydrogen atom, or its equivalent during the acceleration of gravity on the body other bodies with the mass m1, the distance R. A G = is the force of gravity acting between two hydrogen atoms, yes that is the gravitational constant. We prove this by means of a Newtonian apple: Take an apple in her hands and extend your arms in front of him unclench his hand. Now, you can argue that it has fallen apple! Now: Cut the apple into several unequal parts in such a way as to then hold it in your hands to keep the form of the whole apple apple Lift the palm of your hand: and now the answer to the question: apple fell OR MORE OF ITS PARTS? Since during the fall prior to the collision with an obstacle, not an apple fell to pieces, we can conclude that, regardless of the weight and size of an apple or a part of it, the moment of acceleration force of gravity to all parts of the apple is reported equally and simultaneously. Thus, we can divide the apple on forever, but the limiting case is when will the two charges - a proton and electron, an atom of hydrogen. But why not just a proton, electron, or just? Yes, because that is a proton and an electron form a minimum electrically neutral body that is subordinate to the interaction that we are considering. But we have one problem, it's because he neutron is electrically neutral. It is, but we know that a neutron decays into a proton and an electron, in fact we know that atoms neutrons and protons are converted into each other, so with high probability we can assume that the neutron is a composite particle, atom as a whole is electrically neutral, too, so it is possible that the neutron is a kind of a hydrogen atom in an altered state, especially given the instability of the particle and short lifetimes. I'm not going to dispute any theories, I show you the real-state actors prove that these forces are not present and can be for what you have just heard. It is video have information about really force of gravitations: http://www.youtube.com/watch?v=NzeGpbfi8xs so it is russian, please translate it, and you be at shock
