"Histology of the Blood, Normal and Pathological" by Paul Ehrlich and Adolf Lazarus is a seminal work that delves into the intricate structure and function of blood cells. The authors meticulously explore the various components of blood, including red blood cells, white blood cells, and platelets, providing detailed descriptions of their histological characteristics. This book serves as a crucial resource for understanding both normal hematological processes and the pathological changes th...

The desire to understand people’s influence on ecosystems has inspired scientific studies and analyses of the stress individuals and communities place on the environment, human well-being, and the tradeoffs between them. As an emerging discipline, Structural Human Ecology is devoted to unlocking the dynamic links between population, environment, social organization, and technology. The new field offers cutting-edge research in risk analysis that can be used to evaluate environmental polici...

Robert Ornstein and Paul Ehrlich explain that we are causing our own problems because we have created a world where our basic mental functions are no longer suitable. We evolved over a period of millions of years to survive in small tribal families on the wild grassy plains of East Africa. Now the way we live has nothing to do with that time and place, but the mental tools that were developed to survive on the savanna have remained unchanged. These instincts were wonderfully adapted to the...

The pathology of the blood, especially of the corpuscular elements, though one of the most interesting, is certainly one of the most confusing, of all departments of pathology, and to those who have not given almost undivided attention to this subject it is extremely difficult to obtain a comprehensive and accurate view of the blood in disease. Professor Ehrlich by his careful and extended observations on the blood has qualified himself to give a bird's-eye view of the subject, such as few...

In no department of Pathology has advance been so fitful and interrupted as in that dealing with blood changes in various forms of disease, though none now offers a field that promises such an abundant return for an equal expenditure of time and labour. Observations of great importance were early made by Wharton Jones, Waller, and Hughes Bennett in this country, and by Virchow and Max Schultze in Germany. Not, however, until the decade ending in 1890 was it realised what a large amount of ...

Bridging the gap between modern differential geometry and the mathematical physics of general relativity, this text, in its second edition, includes new and expanded material on topics such as the instability of both geodesic completeness and geodesic incompleteness for general space-times, geodesic connectibility, the generic condition, the sectional curvature function in a neighbourhood of degenerate two-plane, and proof of the Lorentzian Splitting Theorem.;Five or more copies may be ord...

One of the major strains on our environment is population growth, and the need for more and more people to be provided for. Listen as Paul Ehrlich, author of the 1968 classic, The Population Bomb, talks about what has gotten better, what is worse, and what to do now.

From the cave walls at Lascaux to the last painting by Van Gogh, from the works of Shakespeare to those of Mark Twain, there is clear evidence that crows and ravens influence human culture. Yet this influence is not unidirectional, say the authors of this fascinating book: people profoundly influence crow culture, ecology, and evolution as well.John Marzluff and Tony Angell examine the often surprising ways that crows and humans interact. The authors contend that those interactions...

Differential geometry arguably offers the smoothest transition from the standard university mathematics sequence of the first four semesters in calculus, linear algebra, and differential equations to the higher levels of abstraction and proof encountered at the upper division by mathematics majors. Today it is possible to describe differential geometry as "the study of structures on the tangent space," and this text develops this point of view.This book, unlike other introductory t...

This book provides a working knowledge of those parts of exterior differential forms, differential geometry, algebraic and differential topology, Lie groups, vector bundles and Chern forms that are essential for a deeper understanding of both classical and modern physics and engineering. Included are discussions of analytical and fluid dynamics, electromagnetism (in flat and curved space), thermodynamics, the Dirac operator and spinors, and gauge fields, including Yang–Mills, the Aharonov–...

Providing a succinct yet comprehensive treatment of the essentials of modern differential geometry and topology, this book's clear prose and informal style make it accessible to advanced undergraduate and graduate students in mathematics and the physical sciences. The text covers the basics of multilinear algebra, differentiation and integration on manifolds, Lie groups and Lie algebras, homotopy and de Rham cohomology, homology, vector bundles, Riemannian and pseudo-Riemannian geometry, a...
