PLANT BREEDING by A. L. HAGEDOORN, Ph. D. Preface: Twenty years ago I wrote my Handbook of Animal and Plant Breeding in the Dutch language, and my Animal Breeding, grew out of the first book. The publishers have asked me to write a plant-breeding book as a companion volume to Animal Breeding with a similar scope and in the same style, and the present work is the result. As a young geneticist, I started my career as a plant-breeding consultant with the French firm of de Vilmorin Andrieux et Cie. After the first years I became more and more absorbed in matters of theoretical genetics, and during the last decade 1 have been chiefly concerned with genetics as applied to man kind and to the breeding of domestic animals. I have, how ever, never quite given up plant-breeding matters, although the only kind of practical plant breeding I have been more directly engaged upon has been the production of sugar-beet seed. This book is certainly not a textbook on Genetics, nor does it pretend to be an exhaustive treatise of everything pertaining to plant breeding. As far as possible, I have throughout the book avoided tht use of technical and scientific terms where plain English would do as well. The book is written in the first place for those who are actively engaged in the ameliora tion of cultivated plants or in the creation of plant novelties. I have quite an extensive experience of correspondence with plant breeders and amateurs, and I have often co-operated with plant breeders during some generations of their material, discussing the results obtained and helping to decide future breeding policy. This co-operation with so many people has 5 6 Plant Breeding helped to give me an understanding of apractical plant breeders difficulties, and it has afforded me some experience in explaining genetic complexities in simple terms. Plant breeding and this is especially true of plant breeding in the larger institutes is subject to fashions, and I have a notion that the preoccupation with higher mathematics is due to a certain extent to one of those fashions. I am convinced that there is very much more in selection, and even in the comparison of the yield of experimental plots, than in matters which can be ap proached only by means of slide-rules and mechanical calculators. Even though the breeding of plants nowadays is chiefly con centrated in the hands of the bigger Institutes and the more important seed firms, there are as appears from my experience large numbers of people interested in plant-breeding subjects. Apart from the host of amateur gardeners and lovers of flowers and fruit, there are thousands of amateur plant breeders, lovers of gardening who sow an occasional bed of dahlia seedlings or who raise a few hundred seedling apple-trees or seedling roses. Since I started as a plant breeder I have become greatly interested in some tropical plant-breeding problems, and as my animal-breeding book seems to have penetrated to all parts of the world, it seems to me that it is necessary to treat of the amelioration of tropical plants as well as of the breeding of plants in our temperate regions. I collected my examples in the five different countries where I have worked. The Dutch book has often been used as a textbook, and in writing the present volume I have taken this possible use into account. It is quite impossible to write a book on plant breeding without going into some technicalgenetical details, and as identical principles and phenomena are met with in both plant and animal breeding, it is unavoidable that some of the first chapters in both books treat of the same matter in much the same way. ..

Have you ever seen a comet? It is a marvelous experience, one that all humans can share, that spawns a deep yearning to understand the spectacle. Have you ever wondered what comets are and why astronomers spend so much time studying them? Now, a comet expert and an astronomical historian have come together to produce the unique book that you now hold in your hands. Using their several decades of teaching experience, the authors have concisely presented the information you need to comprehend these majestic apparitions that grace our night skies. No mathematical proficiency is needed, in fact, this book doesn't contain a single equation! Comets are cosmic Rosetta stones, bridging our current knowledge by digging back to the earliest days of our Solar Systems. How did life arise on Earth? Did comets play a significant role in bringing water and the necessary organic matter to our early Earth? How about the dinosaurs? Were they driven to extinction by a cometary impact 66 million years ago? Comets may be both the enablers and destroyers of life on Earth as we know it. These are some of the tantalizing questions discussed here. If you so desire, steps are given to join the ranks of amateur comet hunters. Astronomy is one of the last sciences where amateurs play a significant role. Your reward for discovery? A comet officially bearing your name in the history books! The next Great Comet is on its way, we just do not know when it will arrive. Armed with this book, you will be ready to enjoy this unforgettable event.

Archie Collins introduces chemistry, first by examining the marvels of air and water, and then revealing the many exciting processes and products discovered by humankind. Written with genuine affection for the subject, the scope of this book gradually expands to encompass the major industries and roles chemistry and chemical processes carry. We learn the basics of combustion, acids, metals and plant life. Gradually, a picture is assembled, demonstrating how chemical processes are crucial to everyday living and human civilization - simply put, from the earliest makings of fire to the most advanced chemical reactions of modern times, human progress has been wedded to advances and discoveries in chemistry. The crops we grow and foods we eat, the clothes we wear and dye, the energy powering our society - all are born of chemical reactions and knowledge. Perhaps uniquely for an educational textbook, Archie Collins demonstrates the importance and scope of chemistry by framing it in a story of human endeavor.
How does a writer discuss her creative process and her views on a writer's role in society? How do her comments on writing relate to her works? The Hindi writer Krishna Sobti (1925-2019) is known primarily as a novelist. However, she also extensively wrote about her views on the creative process, the figure of the writer, historical writing, and the position of writers within the public sphere. This study is the first to examine in detail the relationship between Sobti's views on poetics as exposed in her non-fictional texts and her own literary practice. The writer's self-representation is analysed through her use of metaphors to explain her creative process. Sobti's construction of the figure of the writer is then put in parallel with her idiosyncratic use of language as a representation of the heterogeneous voices of her characters and with her conception of literature as a space where time and memory can be "held." At the same time, by delving into Sobti's position in the debate around "women's writing" (especially through the creation of a male double, the failed writer Hashmat), and into her views on literature and politics, this book also reflects on the literary debates of the post-Independence Hindi literary sphere.
Human chemistry is the study of bond-forming and bond-breaking reactions between people and the structures they form. People often speak of having either good or bad chemistry together: whereby, according to consensus, the phenomenon of love is a chemical reaction. The new science of human chemistry is the study of these reactions. Historically, human chemistry was founded with the 1809 publication of the classic novella Elective Affinities, by German polymath Johann von Goethe, a chemical treatise on the origin of love. Goethe based his human chemistry on Swedish chemist Torbern Bergman's 1775 chemistry textbook A Dissertation on Elective Attractions, which itself was founded on Isaac Newton's 1687 supposition that the cause of chemical phenomena may 'all depend upon certain forces by which the particles of bodies, by some causes hitherto unknown, are either mutually impelled towards each other, and cohere in regular figures, or are repelled and recede from one another'; which thus defines life.
Charles Fort's parade of scientific anomalies frames the larger anomaly that is human existence. "Lo!" is a book with the capacity to rewire brains and sculpt new lenses for seeing the unexpected, the unexplained-and perhaps for glimpsing our own role in Fort's mystifying cosmic scheme.
Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. Hesperides Press are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
When most people think about Catholicism and science, they will automatically think of one of the famous events in the history of science - the condemnation of Galileo by the Roman Catholic Church. But the interaction of Catholics with science has been - and is - far more complex and positive than that depicted in the legend of the Galileo affair. Understanding the natural world has always been a strength of Catholic thought and research - from the great theologians of the Middle Ages to the present day - and science has been a hallmark of Catholic education for centuries. Catholicism and Science, a volume in the Greenwood Guides to Science and Religion series, covers all aspects of the relationship of science and the Church: How Catholics interacted with the profound changes in the physical sciences ("natural philosophy") and biological sciences ("natural history") during the Scientific Revolution. How Catholic scientists reacted to the theory of evolution and their attempts to make evolution compatible with Catholic theology The implications of Roman Catholic doctrinal and moral teachings for neuroscientific research, and for investigation into genetics and cloning. The volume includes primary source documents, a glossary and timeline of important events, and an annotated bibliography of the most useful works for further research
In "Skeptical," author Bob Moores describes his atheistic/humanistic philosophy and traces its roots back to early childhood epiphanies where he first began to question certain axiological teachings. He argues against creationism and religious fundamentalism and defends scientific naturalism, critical thinking, and a rational approach to understanding the world. Moores attempts to show readers how recent scientific discoveries, especially in biology, are more exciting and uplifting than any form of biblical mythology. Using lay terms, he explains the significance of DNA and why a scientific theory is more than just a guess. He argues that modern humanistic values are superior in many ways to those venerated in ancient texts, and he shares his belief that humans are both the greatest threat and greatest hope for the preservation of life on Earth. Moores hopes that "Skeptical" will challenge readers to consider views and information that may conflict with their comfort zones, allowing them to broaden their perspectives. He argues that if we are too protective of our own paradigms, if we stubbornly believe that our way is the only way, then the tribes of earth will never come together to solve the most urgent need of all our continued existence.
This book develops new science of gravity and light based on the century-old Le Sage theory of an "ether" that was replaced by Einstein's Theory of Relativity. After presenting astronomical data contradicting the theory that the universe is expanding from a Big Bang, experiments believed to prove Relativity are shown to actually prove the ether theory instead. Freedom from the speed limit of light enables a science of subatomic particles traveling faster than light to produce gravity, electric and magnetic fields, light, and radio waves. Major technical innovations include solving the two fundamental problems with the Le Sage gravity theory and extending this theory to electromagnetism and consciousness. This is a "theory of everything" that explains the heretofore-unknown causes of the forces of nature. This book builds on the works of Zecharia Sitchin and other authors to explain how life developed on Earth and that evolution requires direction from intelligence that dwells in the subatomic particles on which this theory of gravity and light is based. Our biblical God is shown to be a composite of Sitchin's extraterrestrial "gods" who colonized Earth and the intelligence that dwells alongside our own mind in the particles from which the universe is constructed and powered.
The historic Science Textbook Struggle -- a worldwide battle about the origin of the universe, life, and man -- erupted without warning. It caught the scientific illuminati completely by surprise. Why? Because science textbooks had become filled with wild, unbelievable stories about the beginning of everything. And those tales were simply not scientific The universe starting with a Big Bang, life arising out of a soup of lifeless amino-acids, humans produced by apes . . . those myths had only replaced ancient Greek mythology and were being passed off as scientific truths Caught in the crossfire between educators, news media, textbook publishers, religious notables, and world renowned scientists -- including nineteen Nobel laureates -- was a private citizen. Father of six schoolchildren, he had only one goal: to prove that science never will have answers for origins He was up against the arrogance of scientists who were determined to disguise their private beliefs as being the only explanations for the origin of the universe, life, and man. This story concludes with a great victory for objectivity -- with more than 200 changes being made in textbooks -- over the objections of the National Academy of Sciences. All discussion about origins was transformed -- by admission that stories about them are based solely on personal views of individual scientists. Remarkably, 3,000 scientists around the world later signed an affirmation to assure that this issue of belief-over-fact in science never be repeated. Wernher von Braun, father of America's space program, writes in the Foreword: "Vernon Grose, in tracing out in Science But Not Scientists his personal involvement in the vortex of thesetwo forces, illustrates one more time the humanity of scientists - their likelihood of being just as prejudiced and bigoted as anyone untrained in science. He properly calls for objectivity rather than scientific consensus. He rightly urges that message rather than messenger should be scrutinized and tested for validity. Science will be the richer and humanity the ultimate beneficiary by heeding this clarion call."
