This beautifully illustrated book describes how to record images viewed through a microscope. Dealing with the principles and practice of photomicrography, it is written for all who take photomicrographs, whether beginners or more experienced practitioners. The book describes techniques which may be applied to many disciplines for teaching, research, archives, or pleasure. Techniques for the improvement of contrast are covered in considerable detail. Besides standard photography, the book describes modern digital techniques and there is also a short chapter on drawing. In addition to its value as a work of reference, the authors' clear, didactic style makes this book suitable as a textbook for courses in photomicrography and/or elementary light microscopy.
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.
An introduction to the microscope with colored illustrations, projects, and activities.
Discusses, from a working mathematician's point of view, the mystery of mathematical intuition: Why are certain mathematical concepts more intuitive than others? And to what extent does the 'small scale' structure of mathematical concepts and algorithms reflect the workings of the human brain?
Scanning electr on microscopy (SEM) and x-ray microanalysis can produce magnified images and in situ chemical information from virtually any type of specimen. The two instruments generally operate in a high vacuum and a very dry environment in order to produce the high energy beam of electrons needed for imaging and analysis. With a few notable exceptions, most specimens destined for study in the SEM are poor conductors and composed of beam sensitive light elements containing variable amounts of water. In the SEM, the imaging system depends on the specimen being sufficiently electrically conductive to ensure that the bulk of the incoming electrons go to ground. The formation of the image depends on collecting the different signals that are scattered as a consequence of the high energy beam interacting with the sample. Backscattered electrons and secondary electrons are generated within the primary beam-sample interactive volume and are the two principal signals used to form images. The backscattered electron coefficient ( ? ) increases with increasing atomic number of the specimen, whereas the secondary electron coefficient ( ? ) is relatively insensitive to atomic number. This fundamental diff- ence in the two signals can have an important effect on the way samples may need to be prepared. The analytical system depends on collecting the x-ray photons that are generated within the sample as a consequence of interaction with the same high energy beam of primary electrons used to produce images.
"Yet another cell and molecular biology book? At the very least, you would think that if I was going to write a textbook, I should write one in an area that really needs one instead of a subject that already has multiple excellent and definitive books. So, why write this book, then? First, it's a course that I have enjoyed teaching for many years, so I am very familiar with what a student really needs to take away from this class within the time constraints of a semester. Second, because it is a course that many students take, there is a greater opportunity to make an impact on more students' pocketbooks than if I were to start off writing a book for a highly specialized upper- level course. And finally, it was fun to research and write, and can be revised easily for inclusion as part of our next textbook, High School Biology."--Open Textbook Library.
Awarded for its unique ink illustrations, this newly revised edition of Architecture is Elementary is a self-instruction book that concisely and coherently discusses the principles of architectural design. Stimulating lessons challenge the lay person and trigger creative responses. New features include a fresh design and layout, 50 new illustrations of recent and planned buildings, and new lessons that update the book for the world of twenty-first-century architecture. Author Nathan Winters explains the rationale for developers choosing to build higher and taller with modern high-rises, and explores the engineering challenges for such giant structures. He also addresses the dangers of such adventurous design in this century, including becoming tempting targets for terrorists. Architecture is Elementary also explores issues surrounding modern landscape architecture, as Winters looks at the impact of green design and cities that seek to reclaim useless spaces (such as inactive railroad lines), converting them into parks for urban use. He also explores the financial and economic benefits of beautified landscape. The new layout, new lesson materials, and current examples of future thinking in the world of architecture make this a must-have for every serious teacher, student, and practitioner of architecture.
