The Illustristng Simulations: Public Data Release†

We present the full public release of all data from the TNG100 and TNG300 simulations of the IllustrisTNG project. IllustrisTNG is a suite of large volume, cosmological, gravo-magnetohydrodynamical simulations run with the moving-mesh code Arepo. TNG includes a comprehensive model for galaxy formation physics, and each TNG simulation selfconsistently sol ...

A History of the Unity Game Engine

Unity (commonly known as Unity3D) is a game engine and integrated development environment (IDE) for creating interactive media, typically video games. As CEO David Helgason put it, Unity “is a toolset used to build games, and it’s the technology that executes the graphics, the audio, the physics, the interactions, [and] the networking.” [1] Unity is famo ...

Mesh Networks Delivering IP-Based Seamless Mobility in Municipal and Ad Hoc Wireless Networks

The Motorola vision of seamless mobility goes far beyond the cell phone. Motorola is playing a leading role in a new paradigm for wireless networking: the mesh network. Mesh networks technology is helping to enable the 4th generation of wireless mobility by using basic radio frequency (RF) physics in a new way – overcoming inherent limitations to achieve ...

Science Programmes of Study: Key Stages 1 and 2

A high-quality science education provides the foundations for understanding the world through the specific disciplines of biology, chemistry and physics. Science has changed our lives and is vital to the world’s future prosperity, and all pupils should be taught essential aspects of the knowledge, methods, processes and uses of science. Through building ...

Physics of Soft Matter

These notes were prepared for the one-semester course in theoretical physics of soft condensed matter physics for master students at the Department of Physics, University of Ljubljana. The course consists of 30 hours of lectures and 15 hours of tutorials/seminar. The aim of the course is to provide a broad review the phenomena and the concepts characteri ...

Modern Theory of Nuclear Forces

Modern Theory of Nuclear Forces

Within the Standard Model of particle physics, the strong interactions are described by Quantum Chromodynmics (QCD). QCD is a fascinating theory with many intriguing manifestations. Its structure and interactions are governed by a local non-abelian gauge symmetry, namely SU(3)color. Its fundamental degrees of freedom, the quarks (the matter fields) and g ...

Psychophysics

Psychophysics

In the XIX century and earlier such physicists as Newton, Mayer, Hooke, Helmholtz and Mach were actively engaged in the research on psychophysics, trying to relate psychological sensations to intensities of physical stimuli. Computational physics allows to simulate complex neural processes giving a chance to answer not only the original psychophysical qu ...

Solar Wind and Kinetic Heliophysics

Solar Wind and Kinetic Heliophysics

This paper reviews recent aspects of solar wind physics and elucidates the role Alfvén waves play in solar wind acceleration and turbulence, which prevail in the low corona and inner heliosphere. Our understanding of the solar wind has made considerable progress based on remote sensing, in situ measurements, kinetic simulation and fluid modeling. Further ...

ASTROPHYSICAL PARADOXES, Long Version

ASTROPHYSICAL PARADOXES, Long Version

Astrophysical paradoxes are the paradoxes of physics. The main motivation of a formulated paradox is clearly recognized in the scientific environment because the phenomenon of a paradox itself has become interesting. There is an explanation of how and why the phenomenon of paradox started to exist, as there is an explanation for the existence of any phen ...

The Origins of Medical Physics

The Origins of Medical Physics

The historical origins of medical physics are traced from the first use of weighing as a means of monitoring health by Sanctorius in the early seventeenth century to the emergence of radiology, phototherapy and electrotherapy at the end of the nineteenth century. The origins of biomechanics, due to Borelli, and of medical electricity following Musschenbr ...

Introduction to Laser Physics

The theory of mode structure was outlined in Chapter II, and a number of basic facts concerning mode structure were included in the general description of the ruby (Section 111.1) and the helium-neon laser (Section VA). Here we summarize general experience and supplement the material' already presented, with emphasis on discoveries made during the years ...

Overview of Geophysics

Overview of Geophysics

Geophysics is the application of known physical principles to the study of the Earth. Terrestrial systems, like anything else, obey physical laws, and through applications of these laws quantitative predictions about the Earth’s present physical state and future evolution can be inferred. Geophysics, as a hybrid of geology and physics, requires awareness ...

Polymer Physics

Macromolecules are literally all around us. Many molecules essential to life, such as DNA, RNA, proteins, and polysaccharides, are macromolecules. These giant molecules are responsible for all of the most sophisticated functions in cells, such as transmitting hereditary information, catalyzing chemical reactions, building complex structures, providing me ...

The Properties of Electromagnetic Radiation

The Properties of Electromagnetic Radiation

Field is a physics term for a region that is under the influence of some force that can act on matter within that region. For example, the Sun produces a gravitational field that attracts the planets in the solar system and thus influences their orbits. Stationary electric charges produce electric fields, whereas moving electric charges produce both elec ...

Molecular Physics

There are a number a textbooks to be recommended for those who wish to study molecular spectroscopy; the best ones are: 1)The series of books by Gerhard Herzberg Molecular Spectra and Molecular Structure I. Spectra of Diatomic Molecules II. Infrared and Raman Spectroscopy of Polyatomic Molecules III. Electronic Spectra of Polyatomic Molecules 2)Peter F. ...

Seesaw Mechanism and Its Implications

Seesaw Mechanism and Its Implications

The seesaw mechanism is introduced and some of its different realizations and applications are discussed. It is pointed out how they can be used to understand the bi-large mixing patterns among neutrinos in combination with the assumptions about high scale physics such as grand unification or quasidegeneracy of neutrino masses.
