Introduction to STATICS and DYNAMICS
The following are amongst those who have helped with this book as editors, artists, tex programmers, advisors, critics or suggestors and creators of content: Alexa Barnes, Joseph Burns, Jason Cortell, Ivan Dobrianov, Gabor Domokos, Max Donelan, Thu Dong, Gail Fish, Mike Fox, John Gibson, Robert Ghrist, Saptarsi Haldar, Dave Heimstra, Theresa Howley, Herbert Hui, Michael Marder, Elaina McCartney, Horst Nowacki, Arthur Ogawa, Kalpana Pratap, Richard Rand, Dane Quinn, Phoebus Rosakis, Les Schaeffer, Ishan Sharma, David Shipman, Jill Startzell, Saskya van Nouhuys, Bill Zobrist. Mike Coleman worked extensively on the text, wrote many of the examples and homework problems and created many of the figures. David Ho has drawn or improved most of the computer art work. Some of the homework problems are modifications from the Cornell’s Theoretical and Applied Mechanics archives and thus are due to T&AM faculty or their libraries in ways that we do not know how to give proper attribution. Our editor Peter Gordon has been patient and supportive for too many years. Many unlisted friends, colleagues, relatives, students, and anonymous reviewers have also made helpful suggestions.

Introduction to Differential Geometry & General Relativity
You may be wondering: what holds the neutron star up? Neutrons are chargeless and the nuclear force between neutrons (and protons) is only attractive, so what keeps the neutron star from further collapse? Just as with electrons, neutrons obey the Pauli Exclusion Principle. Consequently, they avoid one another when they are confined and have a sizable kinetic energy due to the uncertainty principle. If the neutrons are nonrelativistic, the previous calculation for the radius of the white dwarf star will work just the same, with the replacement me ’ mn. This change reduces the radius R0 of the neutron star by a factor of ‡2000 (the ratio of mn to me) and R0 ‡ 10 km. One of these would comfortably fit on Long Island but would produce somewhat disruptive effects.

Intermediate Physics for Medicine and Biology
Between 1971 and 1973 I audited all the courses medical students take in their first two years at the University of Minnesota. I was amazed at the amount of physics I found in these courses and how little of it is discussed in the general physics course. I found a great discrepancy between the physics in some papers in the biological research literature and what I knew to be the level of understanding of most biology majors or premed students who have taken a year of physics. It was clear that an intermediate-level physics course would help these students. It would provide the physics they need and would relate it directly to the biological problems where it is useful.

PHYSICS
At one step in the calculation, we note that one million cubic centimeters make one cubic meter. Our result is indeed close to the expected value. Since the last reported significant digit is not certain, the difference in the two values is probably due to measurement uncertainty and should not be a concern. One important common-sense check on density values is that objects which sink in water must have a density greater than 1 g cm3 , and objects that float must be less dense than water.

Impedance Spectroscopy Theory, Experiment, and Applications
The principal audience that will benefit from this book are M.Sc. and Ph.D. students with specialization in physical chemistry, electrochemistry, or physics, as well as researchers and engineers in the field of electrochemistry, particularly in areas of semiconductors, solid electrolytes, corrosion, solid state devices, and electrochemical power sources. Impedance spectroscopy has firmly established itself as one of the most informative and irreplaceable investigation methods in these areas of research. In addition, the book provides a valuable source of information and resource for established researchers and engineers working in one or more of the above fields.

IMAGE ESTIMATION BY EXAMPLE: Geophysical soundings image construction
We make discoveries about reality by examining the discrepancy between theory and practice. There is a well-developed theory about the difference between theory and practice, and it is called “geophysical inverse theory”. In this book we investigate the practice of the difference between theory and practice. As the folklore tells us, there is a big difference. There are already many books on the theory, and often as not, they end in only one or a few applications in the author’s specialty. In this book on practice, we examine data and results from many diverse applications. I have adopted the discipline of suppressing theoretical curiosities until I find data that requires it (except for a few concepts at chapter ends).

Introduction to Groups, Invariants and Particles
This introduction to Group Theory, with its emphasison Lie Groups and their application to the study of symmetries of the fundamental constituents of matter, has its originin a one -semester course that I taught at Yale University for more than ten years. The course was developed for Seniors, and advanced Juniors, majoring in the Physical Sciences. The students had generally completed the core courses for their majors, and had taken intermediate level courses in Linear Algebra, Real and Complex Analysis , Ordinary Linear Differential Equations, and some of the Special Functions of Physics. Group Theory was not a mathematical requirement for a degree in the Physical Sciences. The majority of existing undergraduate textbooks on Group Theory and its applications in Physics tend to be either highly qualitative or highly mathematical. The purpose of this introduction is to steer a middle course that provides the student with a sound mathematical bas is for studying the symmetry properties of the fundamental particles. It is not generally appreciated by Physicists that continuous transformation groups (Lie Groups) originated in the Theory of Differential Equations. The infinitesimal generators of Lie Groups the refore have forms that involve differential operators and their commutators, and these operators and their algebraic properties have found, and continue to find, a natural place in the development of Quantum Physics.

WHERE IS EVERYBODY?
This book is about the Fermi paradox — the contradiction between the apparent absence of aliens, and the common expectation that we should see evidence of their existence. I was fascinated by the paradox when I first met it some 17 years ago, and it fascinates me still. Over those years, many authors (too many to mention here, though their names appear in the reference list at the back of this book) have enthralled me with their writing about the paradox. Their influence upon this work will be clear. I have also discussed the paradox with many friends and colleagues; although they are too numerous to mention individually, I am indebted to them all.

How Buildings Work
Over the past quarter century, the practice of building has undergone significant changes in several areas, notably mechanical, electrical, and communications systems. Researchers have added to our knowledge of building function. New areas of social concern have emerged, especially for buildings that are accessible by all, and for building in a sustainable manner. This third edition, in the tradition of its predecessors, sticks to the basics, but includes hundreds of changes both large and small that reflect the current state of the art and science of building. I have retained the basic organization of the original volume, along with its look and feel, all of which have worn well. The mission and premise of the book remain unchanged.

HOMOLOGICAL METHODS IN EQUATIONS OF MATHEMATICAL PHYSICS
Mentioning (co)homology theory in the context of differential equations would sound a bit ridiculous some 30–40 years ago: what could be in common between the essentially analytical, dealing with functional spaces theory of partial differential equations (PDE) and rather abstract and algebraic cohomologies? Nevertheless, the first meeting of the theories took place in the papers by D. Spencer and his school ([46, 17]), where cohomologies were applied to analysis of overdetermined systems of linear PDE generalizing classical works by Cartan [12]. Homology operators and groups introduced by Spencer (and called the Spencer operators and Spencer homology nowadays) play a basic role in all computations related to modern homological applications to PDE (see below).

General Relativity
General relativity is one of the cornerstones of classical physics, providing a synthesis of special relativity and gravitation, and is central to our understanding of many areas of astrophysics and cosmology. This book is intended to give an introduction to this important subject, suitable for a one-term course for advanced undergraduate or beginning graduate students in physics or in related disciplines such as astrophysics and applied mathematics. Some of the later chapters should also provide a useful reference for professionals in the fields of astrophysics and cosmology.

HIGH-ORDER ACCURATE METHODS FOR MAXWELL EQUATIONS
I would like to express my gratitude and deepest appreciation to Professor Eli Turkel for his guidance, counseling and for his friendship. Without his help and encouragement this work would never have been done. I wish to thank my parents and my sister Maya for their love, support and belief in my success, in spite of the thousands of kilometers between us. I would like to thank my colleagues at Tel Aviv University for their great help, friendship and hours of the scientific (and not too much scientific) discussions.

HENRI POINCARE´ AND RELATIVITY THEORY
The book presents ideas by H. Poincar´e and H. Minkowski according to those the essence and the main content of the relativity theory are the following: the space and time form a unique four-dimensional continuum supplied by the pseudo-Euclidean geometry. All physical processes take place just in this four-dimensional space. Comments to works and quotations related to this subject by L. de Broglie, P.A.M. Dirac, A. Einstein, V.L. Ginzburg, S. Goldberg, P. Langevin, H.A. Lorentz, L.I. Mandel’stam, H. Minkowski, A. Pais, W. Pauli, M. Planck, A. Sommerfeld and H. Weyl are given in the book. It is also shown that the special theory of relativity has been created not by A. Einstein only but even to a greater extent by H. Poincar´e. The book is designed for scientific workers, post-graduates and upper-year students majoring in theoretical physics.
