A New Law of Kinematics

Authors: Joseph Palazzo
Comments: 15 Pages.

Three laws of kinematics are identified. The first two were already known, and are presented with a slightly different perspective. However, the third law of kinematics is a new law of nature. And it states: for every elastic collisions, a free body with the higher kinetic energy can only gain energy from another body with lower kinetic energy, and the lower kinetic energy body will always gain energy from the higher kinetic energy body. Moreover, under general considerations from the theory of Special Relativity, a particle can decay into other particles only if there is a source of positive energy necessary to insure that the new particles have positive kinetic energy, which is why E=mc2 provides the source of this positive energy in the form of mass conversion into energy. Also this new kinematics leads to the reformulation of the 2nd law of thermodynamics which can now explain why heat only flows from a hot body to a cold body, and never the other way around, that a system left on its own will see its disorder increase in time, and that the entropy as defined according to Boltzmann tends to increase. The insight that we gain from this deeper concept which underlies the new law of kinematics and the reformulation of the second law of thermodynamics is that vacuum energy is a necessary condition for particles to pop out of the vacuum. However, this spells trouble for Hawking radiation as it has been formulated - it would lead to a violation of this new kinematics law. Surprisingly this new law of kinematics also sheds new insights into Planck’s ad hoc hypothesis, E = ħω, and why energy must be quantized. As a general conclusion, every dynamical theory must reconcile with this new kinematics.

About a Definition in Time

Authors: Junnichi Fujii
Comments: 3 Pages.

The definition in time in the present-day physics is insufficient. Several problems which are to reconsider a definition in time and concern in time can be settled. This definition isn't inconsistent with general relativity. 4 are supposed. This isn't also inconsistent with general relativity. Mystery in the life expectancy of the neutron can be settled by this. Several dilemmas which concern at time can be settled. It's possible to deepen the understanding simpler than the one of the general relativity.

Experiments Match Simulations in a Multiple Posts Reentrant Cavity

Authors: L. A. N. de Paula, M. Goryachev, M. E. Tobar
Comments: 7 Pages.

Microwave reentrant cavities are used for many applications in sciences and engineering. The potential for high mechanical tunability and high electric quality factors make them important tools in many areas. They are usually resonant cylindrical cavities with a central post which makes a small gap spacing with the cavity wall. By adding an arbitrary number of extra posts, they are generalized to a type of multiple posts reentrant cavity. This new approach has been theoretically studied but no experimental results have been presented. The main purpose of this work is to compare experimental modes with simulation ones from a reentrant cavity made of forty nine cylindrical posts . Each post could be moved using a screw in order to make a tunable gap spacing between the post top and the cavity cover. Eight different gap setups have been made making it possible to investigate thirty six different reentrant modes at room temperature. The lowest frequency percentage agreement between experiment and simulation was 91.31 % and the best one was 99.92 %. Taking into account all the modes, 94.44 % of them had agreement above 96 %. For the first time, an experimental check has been made. This makes the experimental procedure adopted here suitable to investigate the reentrant modes from multiple posts cavities. This new sort of cavities stands for a new technology and can have a wide range of applications once they can gather features of conventional cavities and extra ones.

Lectures on Geometrical Optics for Engineering and Medical Entrance Exam

Authors: Anuj Kumar Dubey
Comments: 196 Pages.

I have been involved from more than ten years in teaching as physics faculty for engineering and medical entrance exam such as IIT (Mains and Advanced)/AIPMT and foundation batch at +2 levels in India. During my interaction with engineering and medical aspirants I, realized that most feared topics in physics is geometrical optics especially in case of solving the numerical problems. Keeping this in mind, i have covered in general the syllabus of geometrical optics, especially for IIT (Mains and Advanced) entrance exam, in these Lecture Notes on “Geometrical Optics”. These lectures contains the topics such as; Basics of optics, laws of reflection and refraction, reflection from spherical mirrors, velocity of image in the plane and spherical mirror, refraction at plane surfaces, prism theory, refraction from curved surfaces, cut lenses, silvered lenses and combination of lenses and mirrors. I have given various numerical problems (fully solved) to discuss the concepts. Very little of these Lecture notes are wholly original. When I drew up notes, I decided from outset that I would collect together the best approaches to the material known to me. So fact is that many of approaches in these Lecture notes have been borrowed from one author or another, there is a little that I have written completely afresh. My intention has been to organize the material in such a way that it is the more readily accessible to majority of the students.

Free Fall Through the Earth

Authors: Bengt Månsson
Comments: 18 Pages.

Free fall through the Earth, considered as a sphere of radially symmetric mass density, along the axis of rotation, is calculated using a general differential equation in newtonian gravity theory. The passage time is calculated and, further, the shape of the tunnel required if the fall is started at an arbitrary point other than a pole, so that the rotation of the Earth comes into play, is determined. Also a general relativistic case with constant density along the axis is considered. -- In this general form the article may also be of some pedagogical value.
