Introduction: Live Version // Discussion // Edit Lesson // Comment // Report An Error // Ask A Question. What is TeX TeX (pronounced Tech) is mainly a low level programming language aimed to typesetting documents. It is very powerful but, since you have to take care of everything, it is difficult to use it for long documents and time-consuming. What is LaTeX LaTeX (pronounced either Lah-tech or Lay-tech) is a macro package created by Leslie Lamport based on the...
Introduction: Human physiology is the study of the functioning of the normal body, and is responsible for describing how various systems of the human body work. Explanations often begin at a macroscopic level and proceed to a molecular level. In 1926, Fritz Kahn portrayed the body as a complex chemical plant, as seen in the painting on the right. This textbook provides an introductory explanation of the workings of the human body, with an effort to draw connections betwe...

Excerpt: The detection of atomic hydrogen in fractional quantum energy levels below the traditional ?ground? state - hydrinos - is reported by the assignment of soft x?ray emissions from the interstellar medium, the Sun, and stellar flares, and by assignment of certain lines obtained by the far-infrared absolute spectrometer (FIRAS) on the Cosmic Background Explorer. The detection of a new molecular species - the diatomic hydrino molecule - is reported by the assignment ...
Introduction: What are Control Systems? The study and design of automatic Control Systems, a field known as control engineering, is a large and expansive area of study. Control systems, and control engineering techniques have become a pervasive part of modern technical society. From devices as simple as a toaster, to complex machines like space shuttles and rockets, control engineering is a part of our everyday life. This book will introduce the field of control engineer...
Introduction: Just What Is a Language? A language is an organized, ordered way of speaking and listening. Reading and writing are a way of representing language in a permanent format, but many languages have no written form. Language is one form of communication. It can be spoken, visual or signed. We can say that language is a code of symbols used to communicate.
Excerpt: The galactic ?dark matter? effect is regarded as one of the major problems in fundamental physics. Here it is explained as a self-interaction dynamical effect of space itself, and so is not caused by an unknown form of matter. Because it was based on Kepler?s Laws for the motion of the planets in the solar system the Newtonian theory of gravity was too restricted. A reformulation and generalization of the Newtonian theory of gravity in terms of a velocity in-flo...

Learning to breathe properly is the first step for everyone. Breathing is the basic fundamental aspect of our physical being. It is something we do all day everyday. It is vital that we have the skills to breathe effectively. Then we give the body the energy it needs to do what it is able to do. The 2nd Edition has over 20 new pages and two new chapters including one on Stress, Weight Loss and Breathing. (www.artofzenyoga.com)
Religious Literature - Methodology of Spiritual Development
Excerpt: People imply different things by this word. Quite right was Gurdjieff saying that each person has his own religion.
Introduction: This is a project of Wikijunior, a collection of free books written especially for kids to learn about science and nature. Many people have been involved with writing this book. This project is hosted on Wikibooks, and you are encouraged to help participate with writing and editing these books.
Excerpt: In the early twentieth century, the instruments of war were simply called weapons. The cannon, the rifle, or the bayonet were all considered separate pieces of weaponry to be used in combat. By the Second World War, technology began to be integrated into combat. The invention of radar and sonar extended the field of combat to greater and greater ranges, and it was no longer necessary to sight targets directly. As technology progressed, the very nature of weapons...
Excerpt: This appendix is taken unmodified from some older lecture notes I wrote for a different class. The notation may be a little different. Consider a container of volume V which contains N atoms, which we will assume are ?structureless? { that is, they contain no internal energy modes (vibration, rotation, or electronic excitation). Let us also assume that the potential energy due to interatomic forces is negligible compared to the kinetic energy of the atoms. These...
Excerpt: This chapter starts with a brief introduction to magnetic properties of solids. The bulk of the chapter concerns mineralogy and magnetic properties of iron-titanium oxides and iron sulfides, which are the dominant ferromagnetic minerals. Essential aspects (such as saturation magnetization, Curie temperature, and grainsize effects) are emphasized because these characteristics strongly affect magnetic properties. A firm grasp of the mineralogy of ferromagnetic min...
Excerpt: We report a simple re-analysis of the old results from the Michelson-Morley interferometer experiments that were designed to detect absolute motion. We build upon a recent (1998) analysis of the original data by Munera, which revealed small but significant effects after allowing for several systematic errors in the original analysis. The further re-analysis here reveals that a genuine effect of absolute motion is expected, in what is essentially a quantum interf...
Excerpt: The previous edition, which was the first, of this National Institute of Standards and Technology (NIST) Technical Note (TN 1297) was initially published in January 1993. A second printing followed shortly thereafter, and in total some 10 000 copies were distributed to individuals at NIST and in both the United States at large and abroad - to meteorologists, scientists, engineers, statisticians, and others who are concerned with measurement and the evaluation an...
Excerpt: Forced Oscillations (Simple Spring-Mass System) Recap of Section 1.3 In the previous section, we discussed how adding a damping component (e. g. a dashpot) to an unforced, simple spring-mass system would affect the response of the system. In particular, we learned that adding the dashpot to the system changed the natural frequency of the system from to a new damped natural frequency , and how this change made the response of the system change from a constant sin...
