Sea fortune has always been an issue of good faith and good navigation. While in antiquity, fortuna gubernatrix was praised for shielding the seaborne trade, in the Renaissance fortuna symbolized the conquest of chance and danger. Under such auspices, while relying on risk technologies modern seafaring has never lost its adventurous dimension. Understanding their origin remains a challenge for the history of science and the history of literature.

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. ..

Conscientious Science is a simplified yet in-depth look into the intricacies of our universe through the fascinating world of theoretical physics. The science of theoretical physics is one of great speculation and hypotheses which rely on proven facts, the results of new and not publicly available experiments, as well as both direct and indirect evidence. Conscientious Science explains complex scientific phenomena in such a way that anyone can understand it. It uses reasonable and plausible explanations to convey and effectively support the theories it explores, while always providing answers to the questions of How? and Why? Conscientious Science is an encounter with forces that no one on this Earth really understands. You may find it shocking, impossible, but it is never the less evidence of the universe beyond the power of our five senses.

This book is all about wisdom for curious minds continuously thriving to become a learned wise man. The objective of this book is not to give readers a fiction or fantasy to create an imagination in readers mind; it is all about scientific, hidden, rare, significant, researchful, historical, philosophical, idealogical, and derived informations. The author also did not miss to deal with conspiring thoughts that has taken shape as cult and ritual practices, which has been beautifully identified from all major religion and questions the preachers and scholars on the topics that were not explained properly and why it has been kept hidden, cautioning the readers and catering with well-perceptioned hints from the actual scriptures.

With over 150 alphabetically arranged entries about key scientists, concepts, discoveries, technological innovations, and learned institutions, the Oxford Guide to Physics and Astronomy traces the history of physics and astronomy from the Renaissance to the present. For students, teachers, historians, scientists, and readers of popular science books such as Galileo's Daughter, this guide deciphers the methods and philosophies of physics and astronomy as well as the historical periods from which they emerged. Meant to serve the lay reader and the professional alike, this book can be turned to for the answer to how scientists learned to measure the speed of light, or consulted for neat, careful summaries of topics as complicated as quantum field theory and as vast as the universe.
The entries, each written by a noted scholar and edited by J. L. Heilbron, Professor of History and Vice Chancellor, Emeritus, University of California, Berkeley, reflect the most up-to-date research and discuss the applications of the scientific disciplines to the wider world of religion, law, war, art and literature. No other source on these two branches of science is as informative or as inviting. Thoroughly cross-referenced and accented by dozens of black and white illustrations, the Oxford Guide to Physics and Astronomy is the source to turn to for anyone looking for a quick explanation of alchemy, x-rays and any type of matter or energy in between.

Natural hazards and anthropic activities threaten the human environment. The gathering of field data is needed so as to quantify the impact of such activities. To gather the necessary data researchers nowadays use a great variety of new instruments based on electronics. Yet, the working principles of this new instrumentation might not be well understood by some potential users. All operators of these new tools must gain proper insight so as to be able to judge whether the instrument is selected appropriately and functions adequately. This book attempts to demonstrate some characteristics that are not easy to understand by the uninitiated in the use of electronic instruments. The material presented in this book was prepared with the purpose of reflecting the technological changes that have occurred in environmental modern instrumentation in the last few decades. The book is intended for students of hydrology, hydraulics, oceanography, meteorology and environmental sciences. Basic concepts of electronics, special physics principles and signal processing are introduced in the first chapters in order to enable the reader to follow the topics developed in the book, without any prior knowledge of these matters. The instruments are explained in detail and several examples are introduced to show their measuring limitations. Enough mathematical fundamentals are given to allow the reader to reach a good quantitative knowledge.

The main subjects of analysis in the present book are the stages of initiation in the grand scheme of Theosophical evolution. These initiatory steps are connected to an idea of evolutionary self-development by means of a set of virtues that are relative to the individual's position on the path of evolution. The central thesis is that these stages were translated from the "Hindu" tradition to the "Theosophical" tradition through multifaceted "hybridization processes" in which several Indian members of the Theosophical Society partook. Starting with Annie Besant's early Theosophy, the stages of initiation are traced through Blavatsky's work to Manilal Dvivedi and T. Subba Row, both Indian members of the Theosophical Society, and then on to the Sanatana Dharma Text Books. In 1898, the English Theosophist Annie Besant and the Indian Theosophist Bhagavan Das together founded the Central Hindu College, Benares, which became the nucleus around which the Benares Hindu University was instituted in 1915. In this context the Sanatana Dharma Text Books were published. Muhlematter shows that the stages of initiation were the blueprint for Annie Besant's pedagogy, which she implemented in the Central Hindu College in Benares. In doing so, he succeeds in making intelligible how "esoteric" knowledge was transferred to public institutions and how a broader public could be reached as a result. The dissertation has been awarded the ESSWE PhD Thesis prize 2022 by the European Society for the Study of Western Esotericism.

PLANTS AND BEEKEEPING an account of those plants, wild and cultivated, of value to the hive bee, and for honey production in the British Isles by F. N. HOWES, D. Sc. PREFACE: There has been a marked increase of interest in beekeeping and the production of honey throughout the country in recent years. This may have been initiated by the Second World War, with the consequent shortage of sweetening materials, and partly by other considerations, such as the better understand ing of some of the major bee diseases that now prevails. The num ber of beekeepers has been doubled or trebled in many localities according to the statistics of Beekeepers Associations and doubtless the total production of home-produced Honey ka MDeen stepped up considerably. It is to be hoped this increase in the Nations annual honey crop will continue, and, what is of even greater importance, that this increase in the nations bee population will also be main tained, for it has been proved that the main value of the honey bee in the national economy is as a pollinator for fruit, clovers, and other seed and farm crops. Its value in this respect far outweighs its value as a producer of honey. Plant nectar has been described as the raw material of the honey industry and those plants that produce it, in a manner available to the honey bee, constitute the very foundations of apiculture. They are obviously of first importance to the beekeeper, whether he or she is a large or small scale beekeeper or belongs to the hobbyist class. A knowledge of these plants and their relative values, for nectar or for pollen, is likely to add much to the pleasure and the profit of beekeeping. An attempt has here been made to deal with themore important bee plants in the British Isles as well as many others that are only of minor importance. Among the latter are to be found both wild and garden plants. Although not sufficiently prevalent in most cases to affect honey yields to any extent such plants have been purposely included in the knowledge that their presence is always beneficial, especially as they so often help to maintain or support bees between the major nectar flows. Much of the pollen collected by bees, so vital for the sustenance of their young, comes from such plants. Furthermore, beekeepers are often keen gardeners and nature lovers and interested in any plant that proves attractive to bees. This no doubt accounts for the present popularity of bee gardens or gardens devoted exclusively to the cultivation of good bee plants, to which a chapter has been given. From the earliest times gardening has been closely associ ated or connected with beekeeping and the two arc obviously complementary and well suited for being carried on together. Many owners of gardens and flower lovers with no special interest in beekeeping derive great pleasure from observing bees industriously at work on flowers and are fond of growing some of those plants which they know will prove a special attraction, even though they may not always be in the front rank as garden plants. Indications are given as to what plants are likely to be most suit able in this connection and special emphasis laid on some of the newer plant introductions. Among the minor bcc plants will be found quite a number of introduced trees and shrubs that are grown to a greater or less extent for ornament. Some of these are important for honey in their native land andwhere this is known the fact is mentioned. As some of these plants, especially among those from the Orient, are of comparatively recent introduction, they may become more generally grown and therefore more useful as bee fodder at some future time. It is for this reason they have been included. The more serious-minded beekeeper and honey producer may be interested only in those plants tluit fill or help to fill his hives. These will be found described at much greater length in Section 2...
