The Wave Basis of Special Relativity
This book offers a simple, intuitive explanation of special relativity. Rather than merely describing the implications of Einstein's postulates, we derive the consequences of special relativity from the wavelike behavior of matter, which is consistent with ordinary physical processes in Galilean spacetime. Topics covered include time dilation, length contraction, Lorentz transformations, four-vectors, and relativistic Doppler shifts. All these aspects of special relativity are direct consequences of the wave nature of matter, and do not imply any interdependence between physical space and physical time. Instead, the strange properties of measured space and measured time in special relativity are artifacts of measurement that naturally arise when using waves (including matter waves) to make measurements.. Properties of matter waves, including the de Broglie wavelength, are also analyzed. The book includes a simple handheld paper model that can be used to visually demonstrate the laws of special relativity.

Air-Cooled Condenser Operation under Varying Ambient Conditions
Scientific Study from the year 2024 in the subject Physics - Thermodynamics, language: English, abstract: The objective of this report is to make up for the following deficiencies at least on a general level - while still using first principles. Air-cooled condensers are widely used at the cold end of thermal power cycles. With this equipment cooling water required in wet cooled power plants may be saved on a large scale. To operate fans which convey dry cooling air to the condenser modules electric power is required which reduces overall power plant effectiveness. Consequently, pumping power consumption should be as small as possible. During operation it is therefore common to reduce fan power consumption by switching down or off fans of individual modules or, in some case complete ACC streets if ambient conditions and operation parameters are promising. Performance guarantees are normally specified with all equipment in full action. Only primary variable variations such as ambient temperature, ambient air pressure or total steam flow rate for a reduced range at fan full speed are part of the performance guarantee. Therefore, effects of fan switch or high cross-wind levels remain open issues.

Life As A Natural Property Of The Universe
Here I present my findings that the solar system mirrors atomic systems and has a quantum mechanical solution to the Schr繹dinger wave equation based on a base unit of 1 second. I further suggest that this solution for our spectral class G2V star the Sun, may indicate that life is a uniform cosmic unfolding throughout the Universe. In order to test whether this works for many G2V stars like our Sun we would need to detect Earth sized planets around other such stars, to see if my Planck constant works for other planetary systems, which I show is connected to my theory for the radius of a proton in terms the Natural constants such as the gravitational constant for gravity and the Planck constant for atoms. Though we measure time with the duration of a second and it came from no idea in Nature but rather how we divided up the day into units since ancient times, it turns out it is a natural duration in this theory and I suggest it is because of how we divided up the day and year from observing the apparent motions of the Sun and stars due to the Earth's motion, that we may have inadvertently had an idea in this that was Natural in terms of the Nature pf atoms and the Earth/Moon/Sun system. Our theory also seems to based on a sixfold symmetry based around the skeletons of life chemistry, the hydrocarbons. I further develop an equation of state for the periodic table of the elements and suggest an intermediary mass between that of the proton and the stars. This results in a constant k that is characteristic of the universe and is in inverse velocity. With these we show it may be that yellow G2V stars with a planet in the habitable zone may be a property of the Universe. I find that the Earth/Moon/Sun system gives the eigenvalue or basis vector for Natural Systems predicting the life span of the Universe in the standard cosmological model. At the end of the paper we apply our theory to another star system, one that is the only one we have detected so far with an Earth-sized planet in it habitable zone. Unfortunately this star is not a yellow G2V star like our Sun, but a red dwarf M star. But we get a feeling for how to apply this theory. The central theme of this paper is that life may be a Natural property of the Universe.

Multifunctional materials
Many applications benefit from sensing of several physical quantities. This is often done by integrating different sensing units or by designing material composites where each material responds to a distinct physical input stimuli. New research trends can be observed in the direction of exploring novel materials that respond to various input signals. These materials can be utilized for multi-modal sensing or for serving different functions in a sensor system such as sensing and storing. This holds particular significance with regard to enhancing the device simplicity and reducing the associated fabrication costs. This thesis explores the versatile properties of bismuth selenide for thermoelectric and thermoresistive sensing in combination with memristive storage. Bismuth selenide was synthesized by means of electrochemical deposition. Here, Bi2Se3 micropillars were achieved for the first time, which are tens of micrometers thick.
Quantum Tant Fant
The Tant-Fant finds its origin in Bengal, India. The original game hereby referred to as the classical game has two players. To develop a basic understanding in the reader's mind, the paper describes the rules and strategies for playing Tant-Fant in detail. The classical game board can be drawn on paper, played on board, or a web reference available. In the classical version, players ought to have three pieces aligned in a row termed as a three-in-a-row either horizontally, vertically, or diagonally but not on the players' initial position also termed as the home row. Alternatively, the players can make specifically a diagonal three-piece alignment also termed a diagonal three-in-a-row. QTF uses the counter-intuitive principles of quantum superposition and collapse to design new moves. The players may choose from either of the two quantum moves, QM1 and QM2 which are equivalent to placing a superposition of pieces in different squares. The quantization of a given game use fewer steps in comparison to classical computation, bringing out previously non-existing strategies for game playing and for tackling more and more complexities in the game. Quantum computers are finding potential applications in almost every field of life. As the quantization of many classical games has already been achieved, the quantization of a lost traditional game would be an interesting feat to achieve.

Descartes on Mathematics, Method and Motion
This book argues that Descartes' physics was a milestone on the road to modern mathematical physics. After Newton introduced a completely different approach to mathematical description of motion, Descartes' physics became obsolete and even difficult to comprehend. This text follows the language of Descartes and the means of which motion can be described. It argues that Descartes achieved almost everything that later Newton was able to do--to describe the motion of interacting bodies- by different (i.e. algebraic) means. This volume completely refutes the received view according to which Descartes' physics was merely a kind of discursive natural philosophy. To make this interpretation more plausible the book follows Descartes' ideas from his early work in mathematics, through his invention of the analytic method towards his mature physics. It shows that Descartes followed a similar heuristic pattern.The volume appeals to students and researchers; it invites the reader equippedwith minimal understanding of college mathematics to follow Descartes on his intellectual journey through the Scientific Revolution. The reader will gain a deeper understanding of the role of mathematical language in the creation of modern physics and a glimpse into the fascinating world of Descartes' scientific thought. Several of Descartes' philosophical ideas can be traced back to his scientific interests and thus the book elucidates the motivation behind some of Descartes' key positions in the area of epistemology and method. In the penultimate chapter the book presents four arguments in favor of seeing Descartes as a physicist on par with Galileo and Newton.
On the Origin of Time
NEW YORK TIMES BESTSELLER - Stephen Hawking's closest collaborator offers the intellectual superstar's final thoughts on the cosmos--a dramatic revision of the theory he put forward in A Brief History of Time. "This superbly written book offers insight into an extraordinary individual, the creative process, and the scope and limits of our current understanding of the cosmos."--Lord Martin Rees Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. In order to solve this mystery, Hawking studied the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse--countless different universes, most of which would be far too bizarre to ​harbor life. Holed up in the theoretical physics department at Cambridge, Stephen Hawking and his friend and collaborator Thomas Hertog worked on this problem for twenty years, developing a new theory of the cosmos that could account for the emergence of life. Peering into the extreme quantum physics of cosmic holograms and venturing far back in time to our deepest roots, they were startled to find a deeper level of evolution in which the physical laws themselves transform and simplify until particles, forces, and even time itself fades away. This discovery led them to a revolutionary idea: The laws of physics are not set in stone but are born and co-evolve as the universe they govern takes shape. As Hawking's final days drew near, the two collaborators published their theory, which proposed a radical new Darwinian perspective on the origins of our universe. On the Origin of Time offers a striking new vision of the universe's birth that will profoundly transform the way we think about our place in the order of the cosmos and may ultimately prove to be Hawking's greatest legacy.

Cosmic Ray Intensity Variation During the Passage of Interplanetary Disturbances
Scientific Study from the year 2024 in the subject Physics - Astronomy, language: English, abstract: An investigation has been made to study the cosmic-ray decreases occurring during 2006 with respect to the arrival times of interplanetary shocks and magnetic clouds. We have identified three interplanetary magnetic cloud events during 5 February 2006, 13 April 2006 and 14 April 2006. The interplanetary magnetic field (B), north-south component of interplanetary magnetic field (Bz), solar wind velocity, sunspot number (R) and disturbance storm time index (Dst) associated with these events has been studied in the present work. Data (neutron monitor count rate) from Newark Neutron Monitor 9NM64 has been used. The north-south component of IMF (Bz) produce large geomagnetic disturbance on the onset of interplanetary magnetic clouds. The deviations in the interplanetary and solar wind plasma parameters are significantly correlated to the magnetic cloud events. The increase in Dst index, sunspot number (R) and Bz after the magnetic cloud event produces increase in cosmic ray intensity.

UFOs and the Pioneers of Oneness
Introducing a unique approach to UFO researchIn this groundbreaking new study, researcher and educator Gerard Aartsen brings a comprehensiveness rarely seen in the inquiry into the reality of extraterrestrial visitors.Referencing the findings of systems science, Aartsen synthesizes and corroborates key elements from the spiritual/philosophical tradition known as the Ageless Wisdom teaching with cross-referenced accounts of those who have been contacted by extraterrestrial visitors. In this way the reader arrives at an entirely new understanding about the nature of life on our planet and in Cosmos itself, devoid of mysticism, sensationalism or superficiality.The threefold character of his methodology is what makes the author's research so exhaustive and his conclusions so compelling. Every chapter overflows with lucid insights derived from the author's synthetic methodology. Momentous world events are placed in context and viewed from the perspectives of the latest science and the ageless wisdom. The world we do have is constantly juxtaposed with the world we can have.In the process, the author reveals how today's ongoing conflicts and perilous tensions are actually the birth pangs of a new sense of oneness, and shows that humanity's problems arise from our inability, as yet, to manifest this essential underlying unity.Going well beyond the question if they are here among us - for which there is evidence in abundance - Pioneers of Oneness elucidates the intrinsic nature of the visitors from space, why they are here, and what is significant about their presence for humanity and our survival.
American Eclipse
On a scorching July afternoon in 1878, at the dawn of the Gilded Age, the moon's shadow descended on the American West, darkening skies from Montana Territory to Texas. This rare celestial event--a total solar eclipse--offered a priceless opportunity to solve some of the solar system's most enduring riddles, and it prompted a clutch of enterprising scientists to brave the wild frontier in a grueling race to the Rocky Mountains. Acclaimed science journalist David Baron, long fascinated by eclipses, re-creates this epic tale of ambition, failure, and glory in a narrative that reveals as much about the historical trajectory of a striving young nation as it does about those scant three minutes when the blue sky blackened and stars appeared in mid-afternoon.In vibrant historical detail, American Eclipse animates the fierce jockeying that came to dominate late nineteenth-century American astronomy, bringing to life the challenges faced by three of the most determined eclipse chasers who participated in this adventure. James Craig Watson, virtually forgotten in the twenty-first century, was in his day a renowned asteroid hunter who fantasized about becoming a Gilded Age Galileo. Hauling a telescope, a star chart, and his long-suffering wife out west, Watson believed that he would discover Vulcan, a hypothesized "intra-Mercurial" planet hidden in the sun's brilliance. No less determined was Vassar astronomer Maria Mitchell, who--in an era when women's education came under fierce attack--fought to demonstrate that science and higher learning were not anathema to femininity. Despite obstacles erected by the male-dominated astronomical community, an indifferent government, and careless porters, Mitchell courageously charged west with a contingent of female students intent on observing the transcendent phenomenon for themselves. Finally, Thomas Edison--a young inventor and irrepressible showman--braved the wilderness to prove himself to the scientific community. Armed with his newest invention, the tasimeter, and pursued at each stop by throngs of reporters, Edison sought to leverage the eclipse to cement his place in history. What he learned on the frontier, in fact, would help him illuminate the world.With memorable accounts of train robberies and Indian skirmishes, David Baron's page-turning drama refracts nineteenth-century science through the mythologized age of the Wild West, revealing a history no less fierce and fantastical.
The Twofold Existence of Particles and Nuclei
This Book contains a new proposal for physics within more than four dimensions (3 spatial dimensions + 1 time coordinate). An extra space is introduced, called basic space, instead of extra dimensions, compactified or otherwise embedded in space-time. A "dual space concept" has been applied by the author to construct models of particles, photons and nuclei mainly in a bottom -- up process. The top - down reasoning, the dominating method in theoretical physics, is only used in a second step. The kind of "twofold existence" discussed in this book turns out to be useful for describing natural systems in the living and non-living world.
