The book series is intended to preserve the cultural legacy and to promote the timeless works of classical literature. Readers of a TREDITION CLASSICS book support the mission to save many of the amazing works of world literature from oblivion. With this series, tredition intends to make thousands of international literature classics available in printed format again - worldwide.

Later this year, the Planetary Society is planning to launch LightSail-1, a sail that will travel farther and farther into space propelled by the sun's steady stream of photon particles. Other such flights are projected for the next few years. This renewed interest in light and its momentum call for a fresh look into the speed of light c which generates this energy. This speed has been, for over a century, a cardinal pillar supporting the present edifice of theoretical physics, but that light had any speed at all was discovered only in the seventeenth century, and confirmed in the eighteenth, by means of measurements over vast astronomical distances. These methods seem to have proven that the speed of light varied with the speed of the observer. Nonetheless, another experiment late in the nineteenth century, was interpreted as showing that the speed of light was independent of its observer or its source-it was a universal constant. This thesis is a meticulous examination in historical context of the evidential data and theories which paved the road to the idea that the speed of light was a universal constant, a seemingly universal belief. The need for the endeavor arose secondarily to the main task of exploring fundamental physical and geometrical phenomena of light detailed in the previous treatises on Optokinetics.

The eternal dichotomy between science and religion. Are they compatible? YES-NO-MAYBE The theory of creation and the theory of evolution are fundamentally at loggerheads with each other. The one being based on faith, the other on reason. The fact remains that the supernatural explanation of the universe is a fantasy; the purpose of our existence, an unresolved mystery; the question of where we are going, the back-pain enigma and gaping hole in the postulate of intelligent design. Are we lost somewhere on a cosmic road to nowhere? If God exists, why does he need all these gigantic fiery celestial marbles to play with? If there is no god, what else is out there, and what shall we call it, him, her? This force can have no gender and must be beyond time as we know it. OCTOPUS MAGNUS

This book has been a work in progress since 1971 in which the author reveals his then, way out ideas and imaginations about the origin of the universe, religion, gender bias in language, future economic and social systems, future space travel and the rectification of PI in a peanutshell. Many of his ideas have now been proven, like the black hole theory and many other ideas are now being considered by the established authorities in their respective fields. And there are many other ramblings and reflections of an active mind that are still crazy but provocative and entertaining.

"Wild Talents" captures Charles Fort at his finest, most thought provoking, and wittiest. Containing accounts of-among numerous other bizarre topics-strange coincidences, vampires, werewolves, talking dogs, poltergeist activity, teleportation, witchcraft, vanishing people, spontaneous human combustion, and the escapades of the 'mad bats of Trinidad, ' the book is essential reading for anyone wanting to learn about the early years of research into the myriad mysteries of this world and beyond.

PREFACE The experience which has led to the writing of this book began in 1929 when, examining a species related to Utricularia gibba, / made an observation of some importance in understanding the mechanism of the trap. This begot a desire to study as many other species of the genus as I could obtain for com parison, primarily to determine the validity of my conclusions. My feeling that research in this field was promising was strengthened by the discovery that the pertinent literature was singularly barren of the information most needed, that is to say, precise accounts of the structure of theentrance mechanisms of the traps. And an examination of much herbarium material, because of the meagreness of the underground parts of the terrestrial types resulting from indifferent methods of collection, forced the conclusion that, even had other difficulties inherent in studying dried material not intervened, it would be necessary to obtain adequately preserved specimens. This meant a wide cor re spondence and, if possible, extensive travel. The uncertainty of achieving the latter made the former imperative. The responses to my requests for help were numerous and generous from all parts of the world, with the result that there came to me from many sources well preserved material which fairly represented the genus, for it brought to me some 100 of the total of 250 or more species. The most lavish single contribu tion was put at my disposal by my teacher and friend, KARL VON GOEBEL, who gave me a collection of Utricularia collected by him in the tropics of the Old and New Worlds, and in temperate Australia. Many others, while they may have contributed less in amount, could have been no less generous, for the work of collecting, preserving, packing and posting specimens is by no means an easy job. Travels included two journeys, one to Africa and one to Africa and Aus tralia, the latter made possible by a parting gift from my colleagues of McGill University on my retirement from the Macdonald Chair of Botany in 1935. At the university centres visited I was afforded all kinds of help: laboratory space, guidance to promising localities and means of transportation. Several summers were spent also at the Botanical Institute of the University of Munich on the original invitation of ProfessorGOEBEL, seconded, after his death, by Professor F. VON WETTSTEIN and his successor Dr. F. C. VON FABER. During my preoccupation with Utricularia / had to prepare two presi dential addresses, and I was thus led, as has many another in like circum stances, to give an account of the whole field of plant carnivory. My interests were widened in this way, and soon I became imbued with the idea of bringing together, and perhaps of adding to, our knowledge of this fascinating group of plants. This extended my list of desiderata. On my requests sent to various correspondent

AN INTRODUCTION TO ELECTROCHEMISTRY by SAMUEL GLASSTONE. PREFACE: The object of this book is to provide an introduction to electro chemistry in its present state of development. An attempt has been made to explain the fundamentals of the subject as it stands today, de voting little or no space to the consideration of theories and arguments that have been discarded or greatly modified. In this way it is hoped that the reader will acquire the modern point of view in electrochemistry without being burdened by much that is obsolete. In the opinion of the writer, there have been four developments in the past two decades that have had an important influence on electrochemistry. They are the ac tivity concept, the interionic attraction theory, the proton-transfer theory of acids and bases, and the consideration of electrode reactions as rate processes. These ideas have been incorporated into the structure of the book, with consequent simplification and clarification in the treatment of many aspects of electrochemistry. This book differs from the au thors earlier work, The Electrochem istry of Solutions in being less comprehensive and in giving less detail. While the latter is primarily a work of reference, the present book is more suited to the needs of students of physical chemistry, and to those of chemists, physicists and physiologists whose work brings them in con tact with a variety of electrochemical problems. As the title implies, the book should also serve as an introductory text for those who in tend to specialize in either the theoretical or practical applications of electrochemistry. In spite of some lack of detail, the main aspects of the subject have been covered, it is hopedimpartially and adequately. There has been some tendency in recent electrochemical texts to pay scant attention to the phenomena at active electrodes, such as ovcrvoltage, passivity, cor rosion, deposition of metals, and so on. These topics, vihich are of importance in applied electrochemistry, are treated here at Mich length as seems reasonable. In addition, in view of tho growing interest in electrophoresis, and its general acceptance as a branch of electrochem istry, a chapter on clectrokinetic phenomena has boon included. No claim is made to anything approaching completeness in the matter of references to the scientific literature. Such reformers as arc given arc generally to the more recent publications, to review articles, and to papers that may, for one reason or another, have some special interest. References are also frequently included to indicate the sources from which data have been obtained for many of the diagrams and tables. Since no effort was made to be exhaustive in this connection, it was felt that an author index would be misleading...

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.

A comprehensive guide to everything scientists need to know about data management, this book is essential for researchers who need to learn how to organize, document and take care of their own data. Researchers in all disciplines are faced with the challenge of managing the growing amounts of digital data that are the foundation of their research. Kristin Briney offers practical advice and clearly explains policies and principles, in an accessible and in-depth text that will allow researchers to understand and achieve the goal of better research data management. Data Management for Researchers includes sections on: * The data problem - an introduction to the growing importance and challenges of using digital data in research. Covers both the inherent problems with managing digital information, as well as how the research landscape is changing to give more value to research datasets and code. * The data lifecycle - a framework for data's place within the research process and how data's role is changing. Greater emphasis on data sharing and data reuse will not only change the way we conduct research but also how we manage research data. * Planning for data management - covers the many aspects of data management and how to put them together in a data management plan. This section also includes sample data management plans. * Documenting your data - an often overlooked part of the data management process, but one that is critical to good management; data without documentation are frequently unusable. * Organizing your data - explains how to keep your data in order using organizational systems and file naming conventions. This section also covers using a database to organize and analyze content. * Improving data analysis - covers managing information through the analysis process. This section starts by comparing the management of raw and analyzed data and then describes ways to make analysis easier, such as spreadsheet best practices. It also examines practices for research code, including version control systems. * Managing secure and private data - many researchers are dealing with data that require extra security. This section outlines what data falls into this category and some of the policies that apply, before addressing the best practices for keeping data secure. * Short-term storage - deals with the practical matters of storage and backup and covers the many options available. This section also goes through the best practices to insure that data are not lost. * Preserving and archiving your data - digital data can have a long life if properly cared for. This section covers managing data in the long term including choosing good file formats and media, as well as determining who will manage the data after the end of the project. * Sharing/publishing your data - addresses how to make data sharing across research groups easier, as well as how and why to publicly share data. This section covers intellectual property and licenses for datasets, before ending with the altmetrics that measure the impact of publicly shared data. * Reusing data - as more data are shared, it becomes possible to use outside data in your research. This chapter discusses strategies for finding datasets and lays out how to cite data once you have found it. This book is designed for active scientific researchers but it is useful for anyone who wants to get more from their data: academics, educators, professionals or anyone who teaches data management, sharing and preservation. "An excellent practical treatise on the art and practice of data management, this book is essential to any researcher, regardless of subject or discipline." -Robert Buntrock, Chemical Information Bulletin

This book gives a rigorous, physics focused, introduction to set theory that is geared towards natural science majors.We present the science major with a robust introduction to set theory, focusing on the specific knowledge and skills that will unavoidably be needed in calculus topics and natural science topics in general, rather than taking a philosophical-math-fundamental oriented approach that is commonly found in set theory textbooks.

Why Science?

We are fascinated by discovery: who discovered what, and how?

This ranges from a look outward at the night sky with scientists like Kepler, astronauts like Neil Armstrong, to physicist like Einstein, chemists like Marie Curie and Linus Pauling, an inward look at psychologists such as Skinner and Maslow, and philosophers like Plato.

Join Keating as he explores the pursuit of scientific discovery from his background as a physicists and a long career in the margins of the academic world.

All Rights Reserved PRINTED IN THE UNITED STATES OF AMERICA THE VA1L-BALLOU PRESS, BINGHAMTON, N t Y T To the memory of THEOBALD SMITH pupil, friend, and master investigator who opened new paths to the human mind. PREFACE IN revising the matter for this, the seventeenth, edition of The Microscope changes have been made in every chapter in text and often in illustrations to render the subject more easily understood. Attention has been called to the newly devised Electron Microscope with its greatly increased magnifying power and resolution over the ordinary microscope to Polaroid for the micro-polariscope to some new plastics for mounting in place of Canada balsam to the high pressure mercury lamps for ultra-violet radiation and the bright mercury lines for photographing objects with the microscope. In general, however, the book retains its former character, and it is hoped that it will continue to serve students and users of the micro scope in understanding the underlying principles involved in micro scopical work. As a final word, I wish to express my thanks and appreciation for the new cuts loaned and other aid rendered by the American manu facturers, the Bausch Lomb Optical Company of Rochester and the Spencer Lens Company of Buffalo. The heads of those com panies, Edward Bausch and Harvey N. Ott, have been my friends and advisers for many years and have been ever ready to help me over the rough places in my microscopical career. Likewise it is a pleasure to render thanks to my University col leagues and to my fellow microscopists for their friendly interest and help also to Clara Starrett Gage, Ph. D. for aid in preparing illus trations, making corrections and revising the index for this edition.
