Erwin Schrödinger (1887-1961) gilt als einer der Väter der Quantenphysik; 1933 erhielt er zusammen mit Paul Dirac den Nobelpreis. Schrödingers Schriften regen auch heute noch an zu einem neuen Blick auf die Welt – und sie haben nicht nur in der Physik weitreichende Folgen gehabt. Schrödinger gilt vielen Experten heute als ein Vordenker des Bioengineering, der Entwicklung von Techniken, mit denen sich Zellen, Gewebe und Lebewesen effizient manipulieren lassen. Und Philosophen attestieren ihm eine orientierende und provozierende Wirkung auf eine neue ökologisch motivierte Philosophie der Natur. In diesem Band entfalten führende amerikanische Naturwissenschaftler und Geisteswissenschaftler das kontroverse Potential von Schrödingers Denken und belegen die anhaltende philosophische und technisch-praktische Bedeutung der Erkenntnisse eines epochalen Wissenschaftlers. "Die Welt ist ein Konstrukt aus unseren Empfindungen, Wahrnehmungen, Erinnerungen. Zwar ist es bequem, sie uns an und für sich einfach schlechthin vorhanden zu denken. Aber sie ist anscheinend nicht schon durch ihr bloßes Vorhandensein auch wirklich manifest." Aus: Erwin Schrödinger, Geist und Materie

Commodity futures prices exploded in 2007-08 and concerns about a new type of participant in commodity futures markets began to emerge. Market participants, regulators, and civic organizations began raising concerns that inflows from new "commodity index" investments were driving the increases in commodity prices instead of economic fundamentals. The main argument was that unprecedented buying pressure from these speculative long-only futures traders created massive bubbles that resulted in prices substantially exceeding fundamental value. At the time, it was not uncommon to link concerns about speculation and high prices to world hunger, food crises, and civil unrest. Naturally, this outcry resulted in numerous regulatory proposals to restrict speculation in commodity futures markets through transaction taxes, speculative position limits, and even the bizarre idea of a "virtual reserve" whereby a public agency would take futures positions opposite speculators. At the core, these assertions raised major economic questions about the efficiency of price discovery in commodity futures markets. Moreover, these so-called remedies did not come without a potential cost. Burdensome regulations would increase compliance and risk sharing costs across the global food system-lowering prices for producers and increasing costs to consumers. To guide this debate, a rigorous approach was needed to understand the dynamics between prices and commodity index activity. This book documents a curated selection of papers on the impact of index investment on commodity futures prices. The chronology of the papers roughly follows the timeline of our involvement in the world-wide debate about commodity speculation as it evolved after 2007. The 10 papers follow the evolving speculation debate with new author forwards highlighting the contribution and impact. Policy-makers, researchers, and market participants will find this not only as useful documentation of the debate; but, also a natural starting point when high commodity prices inevitably create the next speculation backlash.

A plant grows by taking in carbon dioxide from the air and water, as well as nutrients from the soil. Using light energy from the sun, a plant turns these simple materials into more complex organic molecules that add to its increasing size. Plant Development, Second Edition explores this natural process, from the plant as a single cell to a mature organism, giving students a reference point for their understanding of the complex changes in both form and function of a plant's development. This is a valuable tool for students and teachers of plant biology.

Over the past 25 years, terms like genetic modification, genetic engineering, recombinant DNA technology, and biotechnology have become commonplace in the news and in the public vocabulary. But biotechnology has in fact been practiced for thousands of years, with the aim of harnessing organisms for processing food and making useful products. Since the 1980s, however, recombinant DNA technology has given us the ability to modify organisms in the most fundamental way. The modification of plants by these new techniques has unleashed a storm of public controversy worldwide. Plant Biotechnology, Second Edition brings perspective to the discussion. Tracing the history of biotechnology, from its origins in antiquity through its foundations as a science in the work of Louis Pasteur to the birth of modern genetic engineering, this eBook describes traditional uses for plants, reveals how they are genetically engineered, and explains how new technology compares with conventional ways of generating new food plants. Readers will find that this accessible introduction dispels some of the myths surrounding genetic engineering, clearly presents the current impact and future potential of genetically modified plants, and provides a balanced look at the risks and benefits of biotechnology.

The ultimate source of energy is the sun, and the portal through which this life force flows into the biosphere is carried out by green plants. As a result, all organisms—plants, animals, and microbes—use photosynthetic energy for their own needs. Photosynthesis and Respiration, Second Edition introduces the concept of plants as photosynthetic machines and follows the flow of energy and carbon through the natural processes of photosynthesis and respiration. The interaction between photosynthesis and the environment is explored throughout this volume, as well as the role that plants play in balancing the global carbon budget. This reference is a vital tool for students and teachers of biological processes.

This book is a much-expanded and updated edition of a previous volume, published in 1996 as "No-tillage Seeding: Science and Practice". The base objective remains to describe, in lay terms, a range of international experiments designed to examine the causes of successes and failures in no-tillage. The book summarizes the advantages and disadvantages of no tillage. It highlights the pros and cons of a range of features and options, without promoting any particular product.Topics added or covered in more detail in the second edition include:* soil carbon and how its retention or sequestration interacts with tillage and no-tillage* controlled traffic farming as an adjunct to no-tillage* comparison of the performance of generic no-tillage opener designs* the role of banding fertilizer in no-tillage* the economics of no-tillage* small-scale equipment used by poorer farmers* forage cropping by no-tillage* a method for risk assessment of different levels of machine sophistication
