The Case Against Sugar

Gary Taubes
From the best-selling author of Why We Get Fat, a groundbreaking, eye-opening exposé that makes the convincing case that sugar is the tobacco of the new millennium: backed by powerful lobbies, entrenched in our lives, and making us very sick. Among Americans, diabetes is more prevalent today than ever; obesity is at epidemic proportions; nearly 10% of children are thought to have nonalcoholic fatty liver disease. And sugar is at the root of these, and other, critical society-wide, health-related problems. With his signature command of both science and straight talk, Gary Taubes delves into Americans' history with sugar: its uses as a preservative, as an additive in cigarettes, the contemporary overuse of high-fructose corn syrup. He explains what research has shown about our addiction to sweets. He clarifies the arguments against sugar, corrects misconceptions about the relationship between sugar and weight loss; and provides the perspective necessary to make informed decisions about sugar as individuals and as a society.

Time and Free Will

Henri Bergson
"Time and Free Will" is Henri Bergson's doctoral thesis, which was first published in French in 1889. In the work French philosopher Bergson introduces us to his theory of duration, a response to Immanuel Kant's ideas regarding free will as something only possible outside of time and space. Bergson argues that the traditional concept of free will is merely confusion among philosophers caused by an illegitimate translation of the unextended into the extended and a lack of understanding of mechanics. He contends instead that free will is bound to causality and could only be understood in reference to first-person experience and perception. Duration was a way of understanding free will as it referred to each individual person's experience of time, not as a linear mathematical progression, but as something that slows down or speeds up as the person experiences and reflects upon life events. Bergson was one of the most influential philosophers of his day and his ideas, beginning with the publication of "Time and Free Will", profoundly changed the direction of modern European philosophy in the late nineteenth and early twentieth century. This edition is printed on premium acid-free paper and follows the translation of F. L. Pogson.

Chemistry in the marketplace

Selinger, B. K.,Barrow, Russell
Chemicals are everywhere. Many are natural and safe, others synthetic and dangerous. Or is it the other way around? Walking through the supermarket, you might ask yourself: should I be eating organic food? Is that anti-wrinkle cream a gimmick? Is it worth buying BPA-free plastics? This sixth edition of Chemistry in the Marketplace provides fresh explanations, fascinating facts, and funny anecdotes about the serious science in the products we buy and the resources we use. With chapters on the chemistry found in different parts of our home, in the backyard, and in the world around us, Ben Selinger and Russell Barrow explain how things work, where marketing can be deceptive, and what risks you should really be concerned about. This book might even save you some money! With the inclusion of experiments to help apply the concepts in the text, readers with a general interest in chemistry-related disciplines, high school teachers, and university professors will find this book useful and fun.

Oxygen: a play in two acts

Djerassi, Carl
Was treibt Wissenschaftler an? Der Konkurrenzkampf, das Bestreben etwas Neues als erster zu entdecken, ist eine wichtige Motivation. Die moralischen Konsequenzen werden in dem Stück "Oxygen" behandelt, in dem es um die Entdeckung von Sauerstoff geht, dem für das Leben auf der Erde wichtigsten Element. Im Zentrum des Stückes stehen chemische und politische Revolutionen sowie der Nobel-Preis, der 2001 zum 100. Mal vergeben wird. Das Stück spielt 1777 und 2001; zur Aufführung werden drei Schauspieler und drei Schauspielerinnen benötigt, die elf Personen darstellen. Die Urauffühung wird im Frühjahr 2001 in San Diego stattfinden, die deutsche Premiere im September. Die weltberühmten Autoren Carl Djerassi und Roald Hoffmann bürgen aufgrund ihrer Erfahrungen als Wissenschaftler - Carl Djerassi ist bekannt als "Vater der Pille" und Roald Hoffmann erhielt 1982 den Nobelpreis für Chemie - und als Schriftsteller - Djerassi schrieb mehrere erfolgreiche Romane, Hoffmann viel beachtete Lyrik - für Kompetenz und Spannung.

Roald Hoffmann on the philosophy, art, and science of chemistry

Hoffmann, Roald
"Roald Hoffmann's contributions to chemistry are well known; this Nobel laureate has published more than 500 articles and two books. As an "applied theoretical chemist," he has made significant contributions to our understanding of chemical bonding and reactivity, and taught two generations of chemists how to use molecular orbitals for real chemistry. Less well known, however, are Hoffmann's important and insightful contributions to the areas of scholarship surrounding chemistry. Over a career that spans nearly fifty years, Roald Hoffmann has thought and written copiously about the broader context of chemistry and its relationship to the arts and poetry. This book contains Hoffmann's essays and is organized around several major themes: chemical reasoning and explanation, writing and communicating in science, ethics, art and science, and chemical education. A few are unpublished lectures that are valuable additions to the volume. The editors have the full cooperation of Roald Hoffmann in this project. Most of the published work will be reprinted verbatim, but a few of the essays will be revised to eliminate redundancy. The unpublished lectures will also be edited since they were originally intended to be delivered orally at specific occasions. The editors will provide an introduction to the book, and some introductory material for each section. In introducing the material, they will highlight the intrinsic importance and interest of the ideas, as well as the places where Hoffmann's thought makes novel contributions to cognate areas"--

Introduction to Hilbert Space and the Theory of Spectral Multiplicity

Paul R. Halmos
2013 Reprint of 1951 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition Software. The subject matter of the book is funneled into three chapters: [1] The geometry of Hubert space; [2] the structure of self-adjoint and normal operators; [3] and multiplicity theory for a normal operator. For the last, an expert knowledge of measure theory is indispensable. Indeed, multiplicity theory is a magnificent measure-theoretic tour de force. The subject matter of the first two chapters might be said to constitute an introduction to Hilbert space, and for these, an a priori knowledge of classic measure theory is not essential. Paul Richard Halmos (1916-2006) was a Hungarian-born American mathematician who made fundamental advances in the areas of probability theory, statistics, operator theory, ergodic theory, and functional analysis (in particular, Hilbert spaces). He was also recognized as a great mathematical expositor.

Microwave Spectroscopy

C. H. Townes,A. L. Schawlow
Two Nobel Laureates present a systematic, comprehensive account of the theory, techniques, experimental data, and interpretation involved in the study of microwave spectroscopy—a subject relevant to nuclear physics, molecular structure, chemical kinetics, quantum electrodynamics, and astronomy.The material in this volume is discussed critically, systematically, and in the simplest form. The simplicity of the wording and mathematics makes most of the contents accessible to those with a very elementary knowledge of quantum mechanics and atomic physics. Although the treatment is continuously developed, each of the 18 chapters is self-contained. Nearly 200 tables and figures augment the text. Appendixes supply most of the background for research and interpretation of microwave spectra; they also contain extensive data on nuclear and molecular constants, including essentially all those determined by microwave techniques. "Equally suitable for use as a fundamental reference or advanced textbook." — U.S. Quarterly Book Review .

The Jahn-Teller Effect and Vibronic Interactions in Modern Chemistry

Isaac Bersuker
The first half of the title of this book may delude the uninitiated reader. The term '"Jahn-Teller effect," taken literally, refers to a special effect inherent in particular molecular systems. Actually, this term implies a new approach to the general problem of correlations between the structure and properties of any molecular polyatomic system, including solids. Just such a new approach, or concept (in some sense, a new outlook or even a new way of thinking), which leads not to one special effect but to a series of different effects and laws, is embodied in the many ( ~ 4000) studies devoted to the investigation and application of the Jahn-Teller effect. The term "vibronic interactions" seems to be most appropriate to the new concept, and this explains the origin of the second half of the title. The primary objective of this book is to present a systematic develop ment of the concept of vibronic interactions and its applications, and to illustrate its possibilities and significance in modern chemistry. In the first three chapters (covering about one-third of the book) the theoretical background of the vibronic concept and Jahn-Teller effect is given. The basic ideas are illustrated fully, although a comprehensive presentation of the theory with all related mathematical deductions is beyond the scope of this book. In the last three chapters the applications of theory to spectro scopy, stereochemistry and crystal chemistry, reactivity, and catalysis, are illustrated by a series of effects and laws.

Chemistry in theatre: insufficiency, phallacy or both

Djerassi, Carl
This book examines the questions "What can science do for the theatre?" and "What can the theatre do for science?" which raise challenges for both theatre professionals and scientists. Unusually, this book deals with plays first and foremost as reading material -- as texts to be read alone or in dramatic readings -- rather than emphasizing performances on the stage. Concrete examples are given to demonstrate the potential pedagogic value of using the dialogic style and plot structure of plays in science, with a special focus on chemistry.Very few books have dealt with the subject of science-in-theatre and virtually none with chemistry-in-theatre. Texts of the author's two recent plays, Insufficiency and Phallacy, are included in their entirety to offer concrete examples of plays dealing with actual (rather than invented) chemistry. Insufficiency represents an example from the field of beer and champagne bubbles, where the topics of academic tenure and fashion in chemistry are analyzed, whereas in Phallacy, a case history of the similarities and differences between science and art is presented for debate.
