The scientific method is based on experiments and on the mathematical processing of the obtained data in the form of mathematical equations. The fact that this method allows us to predict the outcome of experiments with mathematical accuracy, gives us the feeling that we completely grasp the physical processes.
In this introduction to his papers on the physical nature of the basic concepts of physics such as length, time, velocity, mass, linear momentum, energy, etc., the author demonstrates that this self-confidence is based on a circular reasoning: the experimental data agree with our mathematical equations, because the mathematical equations are quantitative expressions of the experimental data. In that way, the mathematical formulation is not necessarily a description of the physical process, but any description that fits in with the mathematical equation.
It is clear that in that way the ‘laws’ of physics, which consist of the mathematical equations expressed in spoken words, will rather give us a logical insight in the mathematical equations than in the underlying physical mechanism.
This quantitative approach has thereby led to the use of an impenetrable, trivial terminology, with weird concepts, such as ‘force field’, ‘energy field’, ‘curved space-time’, ‘dark matter’, ‘dark energy’, ‘creation’ and ‘annihilation’ of particles, ‘multiverses’, etc. .
To come to a real understanding of the physical processes, the author proposes the approach of a natural elucidating physics’ that allows him to define the physical nature of the basic concepts.

To advance a model describing attributes of nature, we are free to claim properties of the model that we believe support those attributes. Absent real experiments we can perform thought experiments to evaluate whether the assumed properties of the model support the attributes we’re attempting to model. At the same time, we must consider alternative models that may also support those attributes. Our model is not validated unless we can invalidate the alternatives. Two models are examined: the familiar Newtonian model of gravity and inertia and the TI field model of gravity and inertia, which is a concept of this author. These two models differ in how matter objects interact with gravity and how each model supports the propagation of nature’s force particles. We look at these two models to determine which supports correctly the time dilation that occurs during four phenomena: the twin paradox, the Global Positioning System (GPS), a clock in free fall in a gravitational field and a clock at rest on the surface of a gravitational body.

В настоящей книге автор, руководствуясь установкой Исаака Ньютона, что природа во всём предельно проста и экономна и если она чем и наделила тела в процессе их порождения, то одной только силой инерции, в качестве основополагающего принципа действия гравитации рассматривает инерцию. Благодаря подходу, основанному на такой установке, осуществлена категоризация феномена гравитации под такую рубрику опыта как инерция, показана законность её членства в этой категории, закон всемирного тяготения и три остальных закона Ньютона сведены к одному закону – закону инерции, сформулированному и обоснованному задолго до Ньютона Галилео Галилеем.
In this book, the author, guided by the installation of Isaac Newton, that nature in everything is extremely simple and economical, and if she endowed bodies with anything in the process of their generation, then by the force of inertia alone, inertia is considered as the fundamental principle of the action of gravity. Thanks to an approach based on such an attitude, the phenomenon of gravity was categorized under such a heading of experience as inertia, the legitimacy of its membership in this category was shown, the law of universal gravitation and the three other laws of Newton were reduced to one law - the law of inertia, formulated and substantiated long before Newton by Galileo Galilei.

NMR erzeugt in inhomogenen Magnetfeldern nur unpräzise Spektrallinien. Ursache ist die schnell anwachsende Phasendifferenz zwischen den vielen Einzelsignalen. Diese Unterschiede verringern sich durch kurzzeitiges Einschalten zweier magnetischer Hilfsfelder, wodurch die Amplitude des FID-Signals steigt. Wiederholte Phaseninversionen verbessern Dauer und SNR des FID-Signals erheblich und senken die Halbwertsbreite der gewählten Spektrallinie.

In inhomogeneous magnetic fields, NMR produces only imprecise spectral lines. The cause is the rapidly growing phase difference between the many individual signals. These differences are reduced by briefly switching on two auxiliary magnetic fields, which increases the amplitude of the FID signal. Repeated phase inversions significantly improve the duration and SNR of the FID signal and reduce the half-width of the selected spectral line.

Aircraft design is reaching a limit on the greatest airspeed obtainable in the atmosphere. A solution might be to control the boundary layer. During the Second World War, an effort was made to manipulate the layer of air that exists at the surface of aircraft. The system used very small holes along the leading edges of the wings. A compressor forced air through the holes and exhausted the compressed air. This did improve the performance of the planes, but the holes required a great effort to keep clear. Here an effort to control the boundary layer is proposed using the piezoelectric effect. A research effort is described.

In several important previous works [1,2,8-24], each based on the laws of conservation of energy and momentum, the author proposed a new type of rocket engine. The innovated rocket engine extracts energy from the atmosphere as it moves through the atmosphere and uses the harnessed energy to create a powerful propelling thrust. The author shows that if the mass of gas from which the engine is repelled is several times greater than the mass of gas that the engine brakes when receiving energy, then the thrust created by such an engine will be positive. This engine is capable of propelling aircraft to speeds of capable of reaching outer space. In addition, a direct compressor and a motor-generator were invented, in which compression and expansion – the generation of electricity, is produced by an electric field. The author also invented an external rocket-electric motor. All this can make a revolution not only in interplanetary space, but also in future aviation. The cost of fuel is about half the cost of a passenger's ticket in current aviation and almost 90% of the cost of a vehicle-to-space launch. The author uses the word "free" flight or launch in the sense of "without fuel consumption".

предыдущих работах [1,2,8-24], основываяс на законах сохранения энергии и импульса, автор предложил неоычный ракетный двигатель. Двигатель при своем движении извлекает энергию из атмосферы и использует ее для создания силы тяги. Автор показывает, что если масса газа, от которой отталкивается двигатель, в несколько раз больше, чем масса газа, которую тормозит двигатель при получении энергии, то тяга создаваемая таким двигателем, будет положительной. Такой двигатель может разогнать летательный аппарат до космических скоростей. Кроме этого, были изобретены прямочные компрессор и двигатель-генератор, в которых сжатие и расширение – генерация электричества, производится электрическим полем. Aвтором также изобретен внешний ракетно-электрический двигатель. Все это способно сделать революцию не только в космосе, но и в авиации. Стоимость топлива составляет около половины стоимости билета пассажира в авиации и почти 90% стоимости космического запуска. Слово «бесплатный» полет или запуск, автор употребляет в смысле «без расхода топлива».

A photodiode is a semiconductor device that converts light into an electrical current. The current is generated when photons are absorbed in the photodiode. Photodiodes may contain optical filters, built-in lenses, and may have large or small surface areas. Photodiodes usually have a slower response time as their surface area increases. The common, traditional solar cell used to generate electric solar power is a large
area photodiode. Photodiodes are similar to regular semiconductor diodes except that they may be either exposed (to detect vacuum UV or X-rays) or packaged with a window or optical fiber connection to allow light to reach the sensitive part of the device. Many diodes designed for use specifically as a photodiode use a PIN junction rather than a p–n junction, to increase the speed of response. A photodiode is designed to operate
in reverse bias.
