Optically Pumped Magnetometer and Its Application
The optically pumped magnetometer (OPM) is a class of atomic devices that rely on the measurement of Larmor precession of an atomic spin ensemble in a magnetic field. They need the specific frequency light to complete the pumping and detection process. OPMs typically work under the Earth's magnetic field or a limited field. When operating in near-zero field, they can realize the spin-exchange relaxation-free (SERF) regime, thereby promoting a substantial increase in sensitivity. At present, OPMs have been widely used in magnetoencephalography, magnetocardiography, geomagnetic detection, and inertia measurement (comagnetometer). There are a large number of researchers engaged in the study of relevant mechanisms, devices, technologies, and applications. More importantly, supported by MEMS technology and micro/nano optics, OPMs have the potential to move toward chip-scale sensors. This special issue contains some latest developments in OPMs and related areas. We hope the reprint can provide valuable references for researchers in the related field.

Is Dark Energy Gravity?
What if the universe isn't alone - and what we call dark energy is actually gravity reaching us from beyond?Dark energy is the greatest enigma in modern science. Said to make up 72% of everything that exists, it's believed to drive the accelerating expansion of the cosmos - yet no one truly knows what it is, where it comes from, or why it exists.In this provocative and visionary book, Robin Trnovsk羸 introduces SESEMI (Sexual System of Multiverse), a bold new theory that challenges the foundations of cosmology. According to SESEMI, our universe is part of a vast, gravitationally entangled multiverse - and what we perceive as dark energy may in fact be inter-universal gravity pulling from beyond.From stars that seem older than time to galaxies forming too fast, from cosmic asymmetries to the limits of physics itself - this book reinterprets the universe's great mysteries, not by adding new forces, but by reexamining the one we already know: gravity.Is gravity not just a force within our universe - but a bridge between worlds?Whether you're a science enthusiast, a seeker of cosmic truth, or someone who dares to ask "what if?", Is Dark Energy Gravity? offers a captivating journey to the edge of known science - and beyond.The book opens with a concise, enchanting and unprecedented history of astronomy - from ancient stargazers to modern theories of gravity, the Big Bang, dark matter, string theory, the multiverse, and dark energy - showing how our cosmic perspective has evolved and how much still remains unknown.Reality encompasses dimensions beyond the reach of our senses and therefore requires the power of reason to approach its underlying essence.

Detection of Special Nuclear Material With High Purity Germanium and Mercuric Iodide Gamma Detectors
The Defense Threat Reduction Agency (DTRA) contracted for two gamma radiation detectors: mercuric iodide (HgI2) and electromechanically cooled (EMC) high purity germanium (HPGe) to support arms control inspection efforts. This project investigated whether these detectors could measure the quality and quantity of special nuclear material (SNM), particularly Pu-239 for the treaty verification mission. The project investigated two areas of detector capabilities: 1) HgI2 and HPGe detector performance necessary to characterize the quality of plutonium and the presence of shielding materials and 2) HgI2 and EMC HPGe detector performance degradation by high noise levels and EMC HPGe detector performance degradation caused by electromechanical-cooling. The first area studied the response functions of each of the detectors necessary to meet the detection objectives: measure the Pu-239/Pu 240 ratio to identify weapons grade plutonium and to identify a phony weapon. The second area of detector performance evaluated was the EMC HPGe detector's cooling capabilities and its effect on the performance of the detector. The results show that neither of the detectors was ideally capable of supporting DTRA's requirements. The HgI2 detector did not have sufficient efficiency or resolution to distinguish between Weapon Grade and Reactor Grade Plutonium. The EMC system suffered from grounding problems that degraded the resolution and efficiency. An initial study, evaluating the ability of detectors to determine the presence of a simulated tamper within the SNM physics package, showed great promise for identifying phony weapons.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Reduced Computational Cost, Totally Symmetric Angular Quadrature Sets for Discrete Ordinates Radiation Transport
Several new quadrature sets for use in the discrete ordinates method of solving the Boltzmann neutral particle transport equation are derived. These symmetric quadratures extend the traditional symmetric quadratures by allowing ordinates perpendicular to one or two of the coordinate axes. Comparable accuracy with fewer required ordinates is obtained. Quadratures up to seventh order are presented. The validity and efficiency of the quadratures is then tested and compared with the LQn level symmetric quadratures relative to a Monte Carlo benchmark solution. The criteria for comparison include current through the surface, scalar flux at the surface, volume average scalar flux, and time required for convergence. Appreciable computational cost was saved when used in an unstructured tetrahedral cell code using highly accurate characteristic methods. However, no appreciable savings in computation time was found using the new quadratures compared with traditional Sn methods on a regular Cartesian mesh using the standard diamond difference method. These quadratures are recommended for use in three-dimensional calculations on an unstructured mesh.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Operational Defenses Through Weather Control in 2030
The United States needs to incorporate the defense against directed energy weapons with the same intensity used developing anti-ballistic missile defenses. One of the major drawbacks to optical or directed energy systems is the inability to penetrate clouds or dense fog. Advances in technology are beginning to bring weather phenomena under our control. Greatly increased computing power and micronized delivery systems will allow us to create specific perturbations in local atmospheric conditions. These perturbations allow for the immediate and lasting ability to create localized fog or stratus cloud formations shielding critical assets against attack from energy based weapons. The future of nanotechnology will enable creation of stratus cloud formations to defeat DEW and optically targeted attacks on United Sates assets. The solution the weather control problem involves networked miniature balloons feeding and receiving data from a four-dimensional variation (4d-Var) computer model through a sensor and actor network. A network of diamond-walled balloons enters the area to be changed and then both measures and affects localized temperature and vapor content. This system effectively shortens the control loop of an atmospheric system to the point it can be "managed." The capabilities in the diamond-walled balloons are based on the future of nanotechnology.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

From the Microscopic to the Macroscopic
Joel L Lebowitz (born 1930) is a leading figure in the field of statistical physics, whose career has spanned more than seven decades and whose work has left a lasting mark on the theoretical foundations of modern physics. He has held academic positions at Stevens Institute of Technology, Yeshiva University and Rutgers University, where he has served as a distinguished professor. Lebowitz is most known for his contributions to nonequilibrium statistical mechanics and mathematical physics, particularly in the areas of thermodynamic limits, phase transitions, and the foundations of nonequilibrium ensembles.This volume presents the landmark articles that showcase the breadth and depth of Lebowitz's contributions to mathematical physics and statistical mechanics. Ranging from foundational work on nonequilibrium ensembles and quantum measurement to rigorous treatments of phase transitions, transport phenomena, and fluctuation theory, these papers document the development of major ideas in twentieth-century physics. Lebowitz's distinctive approach of combining physical insight with mathematical precision is highlighted clearly, including collaborations with Yakir Aharonov, Peter Gabriel Bergmann, Sheldon Goldstein, Elliott Lieb, Oliver Penrose, Yakov Sinai and Herbert Spohn. This book is both a historical record of scientific progress and a rich resource for active researchers and students in theoretical physics, especially those in statistical physics.
Physics Through Symmetries
Group Theory has been an essential tool of theoretical physics for about a century. During the early days of quantum theory, it was useful to formulate symmetries of systems and to solve for their spectra. Later it was found, in the standard model, that certain groups determine the fundamental interactions of elementary particle. It is not possible to understand modern theoretical physics without knowing group theory.This book is an introduction to group theoretical ideas that arising in classical or quantum mechanics as well as Gield theory. The emphasis is on concepts, although some calculations are done in detail. The intended audience is a graduate student who has already learned mechanics, quantum mechanics as well as some Gield theory (e.g., Maxwell equations in their relativistic form).Among the topics covered are the rotation group and its representations; group extensions and their relevance to spinors; the Lorentz group and relativistic wave equations; the gaussian unitary ensemble of random matrices; the quark model; the Peter-Weyl theorem for Ginite groups as well as compact Lie groups.There are hints that future physics will need symmetries that go beyond the idea of a group. An introduction to such 'quantum groups' is included as well.The book concludes with a study of a class of mechanical systems (Euler-Arnold) which include the rigid body and the ideal Gluids as examples. Some toy models that are one step away from being exactly solvable are studied as examples of chaos.

Statistical Mech Begin (2nd Ed)
This second edition of the popular textbook is intended for all undergraduate students in physics, with some background in thermodynamics. The basic intention of the author is maintained: to present a book for those studying statistical mechanics for the first time. The unique presentation starts off with the principles, elucidating the well-developed theory, and only thereafter the application of theory. Calculations on the main steps are detailed, leaving behind minimal gaps. The author emphasizes with theory the link between the macroscopic world (thermodynamics) and the microscopic world.The book begins with a study of three situations -- the closed system and the systems in thermal contact with a reservoir -- in order to formulate the important fundamentals: entropy from Boltzmann formula, partition function and grand partition function. Through the presentation of quantum statistics, Bose statistics and Fermi-Dirac statistics are established, including as a special case the classical situation of Maxwell-Boltzmann statistics. A series of examples follow: the harmonic oscillator, the polymer chain, the two-level system, bosons (photons, phonons, and the Bose-Einstein condensation) and fermions (electrons in metals and in semiconductors). The treatment of bosons and fermions is expanded with a detailed comparison of their thermal behaviors. A study on neutron stars, a pure fermion system, is now included. The concepts of distribution and fluctuations are also briefly discussed, and an important neglected problem is explained: the equivalence between the sum of a series and the value of the associated integral, teaching further insights on Bose-Einstein condensation. A compact historical note on influential scientists forms the concluding chapter.This book will serve as a vital resource for undergraduates taking their first foray into statistical mechanics, setting a strong foundation for more advanced topics in their studies.

Mathematical Physics and Matrix Representations
This book expounds three kinds of matrices that are of physical interest, centering on physical examples. Stochastic matrices describe dynamical systems of many different types, involving (or not) phenomena like transience, dissipation, ergodicity, nonequilibrium and hypersensitivity to initial conditions. The main characteristic is growth by agglomeration, as in glass formation. Circulants are the building blocks of elementary Fourier analysis and provide a natural gateway quantum mechanics, noncommutative geometry and random walks, including some phenomenology like diffusion-advection equation and prey-predator chains.We also present two applications: chemical reaction and genetics. The last subject may seem specially out of place in 'Mathematical Physics'. Our excuse is that Mendelism and blood types are here presented by using just the same methods of the other chapters. Bell polynomials offer closed expressions for many formulas concerning Lie algebra invariants, differential geometry and real gases, and their matrices are instrumental in the study of chaotic mappings.

The Archive and the Aural City
In The Archive and the Aural City, Alejandro L. Madrid examines the possibilities for retrieving from the archive sounds that were not meant to be heard. Drawing on ?ngel Rama's notion of the Lettered City, Madrid proposes a notion of the Aural City-a Latin American urban intellectual elite for whom sound and listening are central to the creation, re-creation, and circulation of new types of knowledge. While many of these elites carry forward a nationalistic agenda, Madrid contends that the Aural City's archives and the ways they are listened to and conceived through sound and music can also help dismantle dominant frameworks of national or colonial culture and build more inclusive spaces for intellectual exchange and political mobilization. From national archives in Latin America and colonial institutions abroad to sound exhibits, instruments, and internet-based archival projects, Madrid demonstrates how the development of urban spaces is understood through sound. In this way, he expands understandings of the archive's social and sonic power.

This is Ashtars theories that in the end, ends up in instructions for a construct of free energy. The is the second part of "To Be Spirituel" It moves around in many areas within the laws of basic mathematics. And he has his whole own view on how he see an "Atom". And the why's behind. He has his own unique way of thinking. And he did not have any help og aid doing this theory. Other that his basic learnings and teachings in life. He has an education as electrician. Even thou, he also calls himself a "Zero-point engineer". Ashtar do not believe in "Perfection" or "Perfect". "Theres no suchs thing in this universe". He says. Maybe when You have gone trou this theory, you will agree . About "Perfect" and what that is.
Exoplanets and the Search for Alien Life
What if we're not alone in the universe? What if the answer has already been discovered-light years away? This captivating deep dive explores one of humanity's greatest quests: the search for life beyond Earth. With new exoplanets discovered almost daily and space telescopes peering into distant galaxies, the age-old question-"Are we alone?"-is becoming a scientific investigation rather than pure speculation. Inside, you'll explore: - How astronomers detect planets around other stars - What makes a world "habitable" and why Earth-like isn't the only model - The role of water, atmospheres, and biosignatures in the hunt for life - How missions like Kepler, TESS, and JWST are rewriting what's possible - The philosophical and cultural implications of finding alien life From the chemistry of life to the silence of the void, this book invites you to witness the epic, unfolding journey to understand our place in the cosmos. Whether you're a stargazer, science lover, or deep thinker, this is your gateway to the thrilling frontier of planetary exploration.
Enhancement of Heat Transfer in Solar Air Heater
An investigation is done in relation to heat transfer enhancement in solar air heaters with circular V-shaped down ribs. Ribs were attached to the absorber plate, having an angle of attack (α= 60 ⁰). The ratio of rib height to hydraulic diameter (e/D) was 0.047, while the range of rib pitch-to-height ratio was (P/e = 4, 8, and 16) mm for three different sheets, with the Reynolds number ranging from (Re = 1825-7759). The roughened wall of the duct is heated by direct sunlight, while the remaining three walls are insulated. The concept of a V-shaped rib was developed to capitalise on this span-wise variation of heat transfer for inclined ribs. The V-shaped rib reduced the span-wise variation of heat transfer and increased average heat transfer.
Theoretical Issues on Systems Science
In "Theoretical Issues on Systems Science", we present theoretical issues including theoretical incompleteness, multiplicity, systems as networks and chaos, game theory, and meta-structures. Other less explored research topics include equivalence and tolerance in systems, pending systems, recurrence and self-reflexivity, remote synchronization, and the significance of using complex numbers in system models.The first group of papers addresses theoretical aspects, including 1) the role of noise in complex systems; 2) the potential of general systems theory to serve as a theory of everything; 3) the drawbacks of applying classical axiomatic deductive mathematical approaches to topics such as control evolution by rewriting DNA "instructions"; 4) the near non-existence of purely "theory-free" approaches and the balance between theoretical and empirical contributions; 5) the neglect in reductionism in that systems acquire properties and the assumption that multiple, variable interactions of complexity can be analytically "zipped"; and 6) tree-based methods for statistical learning, for which the author presents a systems theory-based framework to speed up discrete event system stochastic simulations.The second group of papers examines theoretical aspects within specific fields, including 1) human dynamics; 2) human cognition; 3) complex physiological processes; 4) medicine; 5) chemical organization theory; and 6) psychotherapy.

Planetary, Lunar and Solar Positions, 601 B.C. to A.D. 1, at Five-Day and Ten Day Intervals
The need for these tables became pressing when hundreds of astronomical cuneiform tables in the British Museum became available for study, partly through the copies made in the 1880s and 1890s. All these texts originally came from some archive in Babylon which was discovered by Arabs in the middle of the 19th century. Most of the texts were written from about 330 B.C. to the first century A.D. Many of the texts are fragments of the original clay tables which have broken. In many cases, a fragment contains only parts of a few legible lines. Much of the information is of an astronomical character. It is evident that for investigations of these tablets the possibility of rapid scanning of accurately dated planetary positions is of primary importance.

Planetary, Lunar, and Solar Positions, A.D. 2 to A.D. 1649, at Five-Day and Ten-Day Intervals
These tables for A.D. 2 to A.D. 1649 are an extension, with some improvements, of earlier ones for 601 B.C. to A.D. 1. As before, they give the geocentric positions (tropic celestial longitudes & latitudes, i.e. with respect to the mean equinox of date), in units of 0 degrees.01 for the Sun & planets, & 0 degrees.1 for the Moon, at 16h Universal Time - 4 P.M. Greenwich Civil Time - 7 P.M. local mean time of 45 degrees East longitude (Babylon), on the indicated dates, all in the Julian calendar, hence for Julian dates 5n + 1/6 for the Moon, Mercury, & Venus, & 1-n + 1/6 for the Sun, Mars, Jupiter, & Saturn. The same adaptation of the theories of Leverrier, Gaillot, & Hansen, with modified elements by Schoch, was used as before, except as noted below. The chief change has been to improve the positions of Jupiter & Saturn. Tables.
