The Evolution of the Microscope covers some of the features of the history of the microscope and the rationale of the design features found in microscopes. The book discusses the first microscopes, the compound microscope in England (1650-1750), simple or single-lens microscopes, and the development of the achromatic microscope. The text also describes the microscope in Victorian times as well as the optical microscope since 1880. The search for greater resolving power such as the ultra-violet and electron microscopes is considered. Scientists and microscopists will find the book invaluable.
This is a brief history of the development of microscopy, from the use of beads and water droplets in ancient Greece, through the simple magnifying glass, to the modern compound microscope. The technology and optical theory are developed in a straightforward manner, and this leads to a description and explanation of the most modern technologies in electron microscopy, and scanning electron microscopy as well as the new scanning probe microscopies. A series of very interesting applications of the various microscopic techniques are described. The most recent pioneering techniques in near field and confocal optical microscope technologies are described and evaluated for their future importance.
This book offers a guide to the microscopic study of metallic ores with reflected light. It combines a rigorous approach with an attractive and easy-to-follow format, using high-quality calibrated photomicrographs to illustrate the use of color for ore identification. The ore identification methodology is updated with systematic color analysis and the application of new multispectral reflectance datasets, which offer an efficient tool for automated ore characterization. In addition, the first volume of this two-part work discusses the essential gangue minerals. Readers will gain familiarity with the method as they follow its application to over 200 selected minerals, comprising the most important ore (≈150) and gangue (≈50) minerals, which are described in the text. Each entry includes an explanatory text with corresponding color photomicrographs for each of the most common microscope settings, preceded by a table summarizing the ore’s main properties, and followed by spectral information in the visible and near-infrared ranges (specular reflectance values from 370 to 1000 nm). Some uncommon, strategic ores, e.g. columbotantalite (“coltan”) and monazite, receive particular attention or are described for the first time with reflected light. Lastly, the book presents a learning strategy for beginners and students. The approach is essentially practical, focusing on the development of observation skills, including self-checking through proposed practical tasks. In addition, the traditional use of determinative tables is critically reviewed and updated. This book is part of a two-volume work. The second volume focuses on intergrowths/textural analysis and interpretation, as well as computer-vision-based automation and applications to ore processing/geometallurgy. The intended audience includes professionals and engineers dealing with mineral resources, as well as postgraduate students. The book also provides lifelong learning support for freelancers and a valuable reference resource for practical university teaching.
The Microscope: Past and Present discusses the best methods of using microscope. This book presents a concise account of the development of this valuable tool, which is used at some time or another by almost every scientist. Comprised of seven chapters, this book begins with an overview of the factors that stimulated the rapid progress in microscopy. This text then describes the immense importance of the work of Robert Hooke in the development of optical devices for assisting the human eye. Other chapters consider the different types of compound microscopes and describe the single-lens or simple microscopes. This book discusses as well the development of the mechanical aspect of the microscope that resulted in a vast increase in the professional use of the microscope. The final chapter deals with the development of electron microscopes. This book is a valuable resource for medical students, scientists, and specialist workers in all fields of industry.
In The Demon Under the Microscope, Thomas Hager chronicles the dramatic history of sulfa, the first antibiotic and the drug that shaped modern medicine. The Nazis discovered it. The Allies won the war with it. It conquered diseases, changed laws, and single-handedly launched the era of antibiotics. Sulfa saved millions of lives—among them those of Winston Churchill and Franklin Delano Roosevelt Jr.—but its real effects are even more far reaching. Sulfa changed the way new drugs were developed, approved, and sold; transformed the way doctors treated patients; and ushered in the era of modern medicine. The very concept that chemicals created in a lab could cure disease revolutionized medicine, taking it from the treatment of symptoms and discomfort to the eradication of the root cause of illness. A strange and colorful story, The Demon Under the Microscope illuminates the vivid characters, corporate strategy, individual idealism, careful planning, lucky breaks, cynicism, heroism, greed, hard work, and the central (though mistaken) idea that brought sulfa to the world. This is a fascinating scientific tale with all the excitement and intrigue of a great suspense novel.
Providing an overview of God's world through a microscope, this book gives a brief history of microscopes before diving into seeing the world through one. Starting with their simple origins in the 13th century as magnifying glasses and exploring some of the many modern varieties of imaging, we explore how they are used and some of what may be seen through one now.Filled with full-color microscopic images of varied animals, insects, plants and fungi, and microorganisms, as well as detailed information for using the modern microscope in the classroom.Discusses examples of stained and unstained slide samples, brightfield, darkfield, and phase contrast microscopy.Includes practical tips about the use of the microscope and labels many of the slide images for easier identification of microscopic structures.Though this is an independent text that can be used with any biology study, it also serves as a companion book in the Master's Class Biology: The Study of Life From a Christian Worldview high school course available from Master Books®. Those who purchase this book would not have to purchase a microscope in order to fulfill the requirements.
This book has evolved by processes of selection and expansion from its predecessor, Practical Scanning Electron Microscopy (PSEM), published by Plenum Press in 1975. The interaction of the authors with students at the Short Course on Scanning Electron Microscopy and X-Ray Microanalysis held annually at Lehigh University has helped greatly in developing this textbook. The material has been chosen to provide a student with a general introduction to the techniques of scanning electron microscopy and x-ray microanalysis suitable for application in such fields as biology, geology, solid state physics, and materials science. Following the format of PSEM, this book gives the student a basic knowledge of (1) the user-controlled functions of the electron optics of the scanning electron microscope and electron microprobe, (2) the characteristics of electron-beam-sample inter actions, (3) image formation and interpretation, (4) x-ray spectrometry, and (5) quantitative x-ray microanalysis. Each of these topics has been updated and in most cases expanded over the material presented in PSEM in order to give the reader sufficient coverage to understand these topics and apply the information in the laboratory. Throughout the text, we have attempted to emphasize practical aspects of the techniques, describing those instru ment parameters which the microscopist can and must manipulate to obtain optimum information from the specimen. Certain areas in particular have been expanded in response to their increasing importance in the SEM field. Thus energy-dispersive x-ray spectrometry, which has undergone a tremendous surge in growth, is treated in substantial detail.
