Journal of Applied Physics

Journal of Applied Physics Exploring the underlying physics of modern technology, Journal of Applied Physics publishes significant new results in applied physics. http://jap.aip.org

Journal of Applied Physics is the American Institute of Physics' (AIP) archival journal for significant new results in applied physics; content is published online daily, collected into two online and printed issues per month (24 issues per year). The journal publishes articles that emphasize understanding of the physics underlying modern technology, but distinguished from technology on the one side and pure physics on the other. Applied Physics Reviews is a series of occasional review articles on topics within this scope. The Proceedings of the Conference on Magnetism and Magnetic Materials is an annual feature.

💥💥💥💥 AGAIN ABOUT ACTION REACTION AND GALILEO According to Newton’s propositions, if a big mass A pushes by action a small mass B the B reacts the same but it is pushed back because it has smaller inertia mass-stability. BUT if it was so, and the inertia was just stability, the B would be pushed back and the A would not move forward. So in fact it is the moving action that absorbs the reaction here , so the reaction seems smaller than the action. 🌟🌟As known Galileo proposed that all bodies heavy and light fall together with the same rythm in vacuum without air. HOWEVER : if we let fall from 2 m a 1000 kg disk and a small piece of paper, the disk falls faster although it’s surface is much bigger. So here it is not the air that makes the heavier fall faster as Galileo proposed. So in vacuum the all issue becomes fluid, especially in big heights. 🌟🌟So suppose that the falling disk has 1000 down and 500 up air resistence hence 1000/500. So SPEAKING WITH LOGIC. if the paper has 10 down , it has 5 up hence 10/5. So they would fall the same in the air, but this does not happen. So all these are proved fluid , and complex propositions.
💥💥💥💥 AGAIN ABOUT GALILEO As known Galileo proposed that all bodies heavy and light fall together with the same rythm in vacuum without air. HOWEVER : if we let fall from 2 m a 1000 kg disk and a small piece of paper, the disk falls faster although it’s surface is much bigger. So here it is not the air that makes the heavier fall faster as Galileo proposed. So in vacuum the all issue becomes fluid, especially in big heights.
💥💥💥💥 WHY THE LIGHT IS STABILITY IN MOTION The light is an electromagnetic field. A moving magnetic field creates electric field and the opposite. It is proposed (typically) that a stable magnet does not have electric field. But if such a nihilistic inertia not moving cituation existed , then it would not be 🌟BRIGHT🌟 with light. In fact there is always electric field in a magnetic field and the opposite. A stable magnet next to a spiral (where they don’t move regarding each other and regarding us here on earth) with electric charges, has always some electric field although this cannot be observed. (There is also some magnetic field in the spiral). In this case where they don’t move regarding each other , as known the charges stay stable in the spiral. Of course in fact we, the magnet and the spiral “move” because of the earth’s “movement”. 🌟🌟SO ESSENTIALLY THE DIVINE LIGHT IS ALWAYS HERE BRIGHT🌟🌟.
💥💥💥💥 ABOUT THE DASEIN ETERNAL DYNAMIC START : The always Dasein Psychological Divine Dynamic is a balanced, and timeless eternal Start (and not a typical time beginning). It is not meteorized somewhere out there and it is not motionless somewhere in here. It’s movements are certain, perfect and normal : they are maneuver and straight combined. That is, it refers to a squared circle, meaning that in it the line (string) and the curve (arc) are harmonized. Since it is a primary Dynamic, the uncertainties and attempts are not primary , but a wrong secondary perspective of it, since it is always here. (When we are certain we project certain certainty. When we are uncertain, we project certain uncertainty). The Eternal Start Dynamic is Stability in Motion (combined). It is the balanced unification of the subjective consciousness and the objective phenomenological perception, and it is Total. (It is -above Newton’s so called action-reaction- , a rather Hegel’s unification of the opposites in a Dasein higher level where they Move together). It is Complete and Total and Moves forward, filling the void, gap, vacuum.
💥💥💥💥 THE BIG SECRET OF INERTIA A so called inertia system considers itself not moving but stable. The secret of inertia (stability-non movement) is that in fact the movement is total : there is a so called “reaction “ to action movement not because the real cituation is a nihilistic-monistic point stability but because the real Action movement is Total (Hegel type) above the opposites that are harmonized in this Total United movement. The all Issue is Hegel type and not exactly Newton type : it is more fluid and complex than Newton thought because the action and “reaction” are harmonized and move United in this Higher Level. Also it is not exactly as Hegel thought : he (as the Kabbalah) thought that deep down its all good and that even the bad circumstances work for good. But it is dangerous to think that a crime or a bad action works for good. It is not a good principle. However the opposites do unite in a higher Hegel type United Divine morphologic field. So as we have said , 🌟stability in movement🌟 is the balance key word. 💥💥💥💥 There is a so called “reaction” because the action is individual. The real Action is collectivistic (and there are not real resistance reactions there). 💥💥💥💥 In this flying chariot of the soul the stability and the movement ride together. Its like a flying wild horse that is flying like Pegasus high in the Dasein heaven psychological level. Where does it go, well see in next posts.
Impedance of Skin-Plasma Effect. Ordin S.V. Ioffe Institute RAS. Abstract The scale of nanoelements has raised the question of the applicability of some well-known optical models. And the analysis of the limits of their applicability showed that the work begun by Planck on the elimination of false singularities in the functions used in physical models has not been completed in many respects. In this regard, the reaction of free electrons to radiation was also previously described in a fragmentary-classical way, within the framework of the skin effect and plasma reflection, which led to a kind of ultraviolet and infrared catastrophe. Understanding the general problem required the elimination of this fundamental "catastrophe", and not with the help of corrections of the "anomaly" type used, in principle, of the same models. Normalization of the frequencies of emission and decay of electrons to the plasma frequency made it possible to obtain a general qualitative picture of the dynamic electron response to radiation in the form of a semiempirical size-dependent function of generalized skin-plasma absorption, a kind of Planck function for real decaying plasmons. An in-depth analysis of this function led to an understanding of the fundamental feature of describing the dynamics of free electrons using the well-known electrical impedance, traditionally perceived as a purely radio-technical parameter, but in reality giving a more complete description of a harmonic oscillator than a purely mechanical oscillator. So the generalization of the models describing the reaction of free carriers to radiation one-sidedly led to the need to take into account not only Quantum Mechanics, but also Quantum Electronics. The analysis of the Foundations of the newly created Quantum Electronics revealed that the final impedance of the vacuum determines the minimum attenuation and thus the boundary of the physical values of the models used. In general terms, it is the vacuum impedance that determines both the complexity of the refractive index of the vacuum and the maximum visibility limit in the Universe. On the basis of the described boundary effect on free electrons, optimizing the geometric nano-dimensions in weakly absorbing media within the framework of the obtained model, it is possible to create fundamentally new active bipolar elements of electronics. Key words: plasma reflection, skin effect, model applicability limits, Planck function, oscillatory circuit, New Quantum Electronics.
💥💥💥💥 GOLDEN RATIO AND TRINITY The golden ratio is said to be 1,618.... . If the line a is bigger that the line b in a certain level, then (a+b) / a = a/b = 1,618... . BUT : this needs 2 lines a,b as parts of a third unified line (a+b) which is one big line. So the golden ratio needs from the Start 2 in 1 (hence the Trinity from the Start) and not from the start just 1 line that later is cut in 2. It also is above the typical numbers. Here the 1 and the many, the stability and the movement , the pointer and the axis are in fundamental balance. (Also the Fibonacci proposition that all numbers are the outcome of 0+1 is rather unreal). LETS ALSO NOTICE THAT THE 1,618.... IS NOT A QUANTUM SUBDIVISION BECAUSE IT IS 1,6..... AND NOT 1.
Neutron Based Table of Elements invented by James T. Struck BA, BS, AA, MLIS shows that neutrons can be the basis of a chemical element table. My drawings also show the lanthanides and actinides can be integrated with the rest of the Chemical Element table. Neutrons are slightly larger than protons, so Neutrons are just as useful as protons in being the basis of a chemical element table. Both protons and neutrons can also be shown as well. Now a new alternative to Russian Dmitri Mendeleev's table is shown. James T. STruck PO BOX 61 Evanston IL 60204
💥💥💥💥 ABOUT THE GALILEO SLIDE SLOPES, THE EINSTEIN - MINKOWSKI DIAGRAMS AND THE FALL OF THE BODIES : As we said, Galileo proposed that all bodies heavy and light fall the same in vacuum. He said tht he saw that in so called experiments with SLIDE slopes. He said that time is represented by the horizontal distance and space the vertical distance that are covered when the body leaves the SLIDE slope. BUT THOSE THINGS DONT AGREE WITH EACHOTHER : where there is rubbing like in the air or in a ski slope, it is known that the heavy body falls - slides faster than the light. So the heavy body has bigger speed leaving the SLIDE slope and covered bigger distance - time. Also in the Einstein Minkowski diagrams, all bodies move the same in space time, and the more they move in space the less they move in time. Also according to Einstein time is slower in a bigger mas. So the bigger-heavier mass should move less than the small-light mass in time and more in space, and it should fall faster in vacuum. SO ALL THOSE THEORIES AND DIAGRAMS ARE JUST INSTRUMENTAL. THEY SEEM STRONG IN MEDIUM HIGHTS. IN BIG HIGHTS THEY ARE WEAK.
