Chemicals For Life And Living

Chemicals often have a negative Image among the general public. But there is no material world or indeed human beings without chemicals. The material world is operated by chemicals. The title ‘Chemicals for Life and Living’ implies that the material world is staged and played by chemicals. The book consists of five parts and an appendix. Part 1 – Essentials for life; Part 2 – Enhancing health; Part 3 – For the fun of life; Part 4 – Chemistry of the universe and earth, and Part 5 - Some negative effects of chemicals. The appendix gives a brief summary of what chemistry is all about, including a short chapter of chemical principles. No quantitative calculations are included in this book so that it is appealing for everyone – not just chemists.

In this book, the authors describe the long journey from formless inanimate matter to man, explaining the nature and the logic of the physical-chemical processes involved. It stresses the limitations of reductionism analyses of these processes as complexity increases and novel properties emerge. And, in particular, the authors develop the idea that it was chemical change of the environment that allowed evolution of life to occur and that this evolution required successive addition of new message systems and information codes connected, compatible, and cooperative with previous extant systems. In doing so, the authors analyze the relationship between chemical element content and speciation both in inanimate and living systems in terms of fundamental units and variables or composite (derived) units and variables. Through such analysis, the authors conclude that chemical speciation is very much a matter of chemical cooperation (order versus disorder) while biological speciation requires cooperative flow of chemicals and energy (organization versus disorder). They argue that chance mutations of DNA are far too simple to provide a basis for evolution and biological diversity, though it is a representation of such diversity. It is the survival strength of systems of molecular machinery which separate and generate living species. In the final chapter, they analyze the effect of man's activities on the present global and local ecosystems and speculate on the possible nature of the emergent properties to be expected from an ever-increasing complexity of information based modern societies.

Emphasises on contemporary applications and an intuitive problem-solving approach that helps students discover the exciting potential of chemical science. This book incorporates fresh applications from the three major areas of modern research: materials, environmental chemistry, and biological science.

The Principles of Biology sequence (BI 211, 212 and 213) introduces biology as a scientific discipline for students planning to major in biology and other science disciplines. Laboratories and classroom activities introduce techniques used to study biological processes and provide opportunities for students to develop their ability to conduct research.

Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

In Assembling Life, David Deamer addresses questions that are the cutting edge of research on the origin of life. For instance, how did non-living organic compounds assemble into the first forms of primitive cellular life? What was the source of those compounds and the energy that produced the first nucleic acids? Did life begin in the ocean or in fresh water on terrestrial land masses? Could life have begun on Mars? The book provides an overview of conditions on the early Earth four billion years ago and explains why fresh water hot springs are a plausible alternative to salty seawater as a site where life can begin. Deamer describes his studies of organic compounds that were likely to be available in the prebiotic environment and the volcanic conditions that can drive chemical evolution toward the origin of life. The book is not exclusively Earth-centric, but instead considers whether life could begin elsewhere in our solar system. Deamer does not propose how life did begin, because we can never know that with certainty. Instead, his goal is to understand how life can begin on any habitable planet, with Earth so far being the only known example.

Now recognized as one of the most influential books of the twentieth century, Silent Spring exposed the destruction of wildlife through the widespread use of pesticides Rachel Carson's Silent Spring alerted a large audience to the environmental and human dangers of pesticides, spurring revolutionary changes in the laws affecting our air, land, and water. Despite condemnation in the press and heavy-handed attempts by the chemical industry to ban the book, Carson succeeded in creating a new public awareness of the environment which led to changes in government and inspired the ecological movement. It is thanks to this book, and the help of many environmentalists, that harmful pesticides such as DDT were banned from use in the US and countries around the world. This Penguin Modern Classics edition includes an introduction by Lord Shackleton, a preface by World Wildlife Fund founder Julian Huxley, and an afterword by Carson's biographer Linda Lear.
