Mechanics and Physics of Porous Solids addresses the mechanics and physics of deformable porous materials whose porous space is filled by one or several fluid mixtures interacting with the solid matrix. Coussy uses the language of thermodynamics to frame the discussion of this topic and bridge the gap between physicists and engineers, and organises the material in such a way that individual phases are explored, followed by coupled problems of increasing complexity. This structure allows the reader to build a solid understanding of the physical processes occurring in the fluids and then porous solids. Mechanics and Physics of Porous Solids offers a critical reference on the physics of multiphase porous materials - key reading for engineers and researchers in structural and material engineering, concrete, wood and materials science, rock and soil mechanics, mining and oil prospecting, biomechanics.

What is quantum mechanics? The laws of Newton, which work well over a wide range of scale, from planets to billiard balls, fail at the level of atoms and their constituents. Quantum mechanics provides a new set of laws and a mode of description for microscopic systems that has proved supremely successful. Since its inception in the 1920s it has explained the structure of atoms and molecules, nuclear reactions, collisions of particles in accelerators, the emission and absorption of radiation, the thermal and electrical properties of solids, chemical bonding, superconductivity and superfiuidity, the pressure inside collapsed stars, subnuclear matter, and a great deal else. Why is quantum mechanics so important? Besides providing explanations for a wide variety of physical phenomena, the theory has led to a large number of practical applications, among which are the laser, the electron microscope and the microchips of modern electronics. In many research laboratories and high technology industries, devices based on quantum principles are used or developed as a matter of routine. Although the foundations of the subject are well over half a century old, new applications of the theory still have the power to surprise. Why is it so hard to learn? Students find quantum mechanics tough going for two reasons, one conceptual, the other technical. Familiar concepts such as speed, size, acceleration, momentum and energy take on weird features, or even become meaningless. Intuition gained from daily experience is of no help, and can be misleading.

1. We begin by giving a simple example of a partial differential inequality that occurs in an elementary physics problem. We consider a fluid with pressure u(x, t) at the point x at the instant t that 3 occupies a region Q oflR bounded by a membrane r of negligible thickness that, however, is semi-permeable, i. e., a membrane that permits the fluid to enter Q freely but that prevents all outflow of fluid. One can prove then (cf. the details in Chapter 1, Section 2.2.1) that au (aZu azu aZu) (1) in Q, t>o, -a - du = g du = -a z + -a z + -a z t Xl X X3 z l g a given function, with boundary conditions in the form of inequalities u(X,t»o => au(x,t)/an=O, XEr, (2) u(x,t)=o => au(x,t)/an?:O, XEr, to which is added the initial condition (3) u(x,O)=uo(x). We note that conditions (2) are non linear; they imply that, at each fixed instant t, there exist on r two regions r~ and n where u(x, t) =0 and au (x, t)/an = 0, respectively. These regions are not prescribed; thus we deal with a "free boundary" problem.

New Volume 1A edition of the classic text, now more than ever tailored to meet the needs of the struggling student.

Preface This is a two-year elementary college physics course for students majoring in science and engineering. The intention of the writers has been to present elementary physics as far as possible in the way in which it is used by physicists working on the forefront of their field. We have sought to make a course that would vigorously emphasize the foundations of physics. Our specific objectives were to introduce coherently into an elementary curriculum the ideas of special relativity, of quantum physics, and of statistical physics.

What is Quantum Mechanics? A Physics Adventure comprehensively traces the historical development of quantum mechanics, treating a complex subject in a light-hearted, user-friendly manner. It not only introduces the reader to the concepts of quantum mechanics, but also tells the story behind the theories. It is easy to understand for beginners because it was written by people going through the learning process themselves. Yet, even the seasoned scientist will enjoy the controversy and drama as the development of physics unfolds in the book.Dr. Yoichiro Nambu, 2008 Nobel Prize Winner in Physics, served as a senior adviser to the student authors of What is Quantum Mechanics? A Physics Adventure at the Transnational College of LEX throughout their journey of discovery.

Since the 1950s shock compression research contributed greatly to scientific knowledge and industrial technology. As a result, for example, our understanding of meteorite impacts has substantially improved, and shock processes have become standard industrial methods in materials synthesis and processing. Investigations of shock-compressed matter involve physics,electrical engineering, solid mechanics, metallurgy, geophysics and materials science. The description of shock-compressed matter presented here, which is derived from physical and chemical observations, differs significantly from the classical descriptions derived from strictly mechanical characteristics. This volume, with over 900 references, provides an introduction for scientists and engineers interested in the present state of shock compression science.

Quantum mechanics is the key to modern physics and chemistry, yet it is notoriously difficult to understand. This book is designed to overcome that obstacle. Clear and concise, it provides an easily readable introduction intended for science undergraduates with no previous knowledge of quantum theory, leading them through to the advanced topics usually encountered at final year level. Although the subject matter is standard, novel techniques have been employed which considerably simplify the technical presentation. The authors use their extensive experience of teaching and popularizing science to explain the many difficult, abstract points of the subject in easily comprehensible language. Helpful examples and thorough sets of exercises are also given to enable students to master the subject. This book should be of interest to 2nd and 3rd year undergraduate students in physics, chemistry and some electrical engineering courses.

For upper-level undergraduates and graduate students: an introduction to the fundamentals of quantum mechanics, emphasizing aspects essential to an understanding of solid-state theory. A heavy background in mathematics and physics is not required beyond basic courses in calculus, differential equations, and calculus-based elementary physics. Numerous problems (and selected answers), projects, exercises.

The study of mechanics plays a central role in physics for a whole variety of reasons. It was one of the earliest of the quantitative sciences, and had immediate practical applications. These ranged from the study of the motion of projectiles in warfare to the motion of the planets, predicting the seasons, eclipses, etc. At the present time, even though superseded on the very small scale by quantum theory and on the very large scale by the theory of relativity, the mechanics of Newton is perfectly adequate for treating a wide spectrum of problems from the · '"etic theory of gases to the motion of space vehicles. Furthermore, the science of mechanics is regarded by many as the epitome of a good scientific theory and for this reason is studied by philosophers and social scientists alike as an exemplar of the 'scientific method'. We shall commence in Chapter 1 with a brief historical outline of the development of mechanics, mentioning the names and dates of the main participants and summarizing their contributions. Preface vii Chapter 1 Newton's laws 1. 1 Historical introduction Primitive ideas about mechanics were exemplified by the state­ ments of Aristotle (384-322 Be), who asserted that a force was necessary to maintain motion. Furthermore, he believed that there were different laws for heavenly and earthly bodies.
