  • As we sit at the microscope with users, waiting for data to collect, we frequently find ourselves answering the same questions, time after time. The users need to know what their data tells them about the sample, how it should be interpreted or processed, or a myriad of other details about the experiment. At other times, we find ourselves explaining why a particular experiment cannot be performed, or, at least, why it is more complex than appears at first glance. Sometimes students need help describing these issues to their advisors.

  • Encouraged by the friendly acceptance of the first edition and stimulated by numerous requests and comments from the community of meiobenthologists, this second edition updates my monograph on meiobenthology. The revised text emphasizes new discoveries and developments of relevance; it has been extended by adding chapters on meiofauna in areas not covered before, such as the polar regions, mangroves, and hydrothermal vents.

  • In the early part of 1863, while I was resident in London,--the first of the War Correspondents to go abroad,--I wrote, at the request of Mr. George Smith, publisher of the Cornhill Magazine, a series of chapters upon the Rebellion, thus introduced:-- "Few wars have been so well chronicled, as that now desolating America.

  • Microscopy is a servant of all the sciences, and the microscopic examination of minerals is an important technique which should be mastered by all students of geology early in their careers. Advanced modern textbooks on both optics and mineralogy are available, and our intention is not that this new textbook should replace these but that it should serve as an introductory text or a first stepping-stone to the study of optical mineralogy.

  • No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man’s and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water. With infinite complacency men went to and fro over this globe about their little affairs, serene in their assurance of their empire over matter.

  • An ecosystem is a group of animals and plants living in a specific region and interacting with one another and with their physical environment. Ecosystems include physical and chemical components, such as soils, water, and nutrients that support the organisms living there. These organisms may range from large animals to microscopic bacteria. Ecosystems also can be thought of as the interactions among all organisms in a given habitat; for instance, one species may serve as food for another. People are part of the ecosystems where they live and work.

  • Transmission electron microscopy (TEM) is a technique where the electron-beam is transmitted through an ultra-thin specimen, interacting with specimen as it passes through it. An image is formed from the interaction of the electrons transmitted through the specimen, which is then magnified and focused onto an imaging device, such as a fluorescent screen, a photographic film, or a charge-coupled device (CCD) sensor. This technique is capable of imaging at significantly high resolution than the light microscopes, owing to the small de-Broglie wavelength of electrons....

  • The Art of Public Speaking "1_1_8"CHAPTER VIII. CONCENTRATION IN DELIVERY Attention is the microscope of the mental eye. Its power may be high or low; its field of view narrow or broad. When high power is used attention is confined within very circumscribed limits, but its action is exceedingly intense and absorbing. It sees but few things, but these few are observed "through and through" ... Mental energy and activity, whether of perception or of thought, thus concentrated, act like the sun's rays concentrated by the burning glass. The object is illumined, heated, set on fire.

  • Various mesoscopic systems have their own unique characteristics, some of which are of importance due to bridging function over classical and quantum mechanics. It is quite natural that human beings living in macroscopic world could hardly grasp the phenomena occurring in the microscopic world in an intuitive manner. This situation offers a vital sense in the "observation" problem necessarily accompanied with the classical means. The fundamental core of the argument between Einstein-Podolsky-Rosen and Bohr starting in 1935 actually lies in this point.

  • With the advent of the atomic force microscope (AFM) came an extremely valuable analytical resource and technique, useful for the qualitative and quantitative surface analysis with sub-nanometer resolution. In addition, samples studied with an AFM do not require any special pretreatments that may alter or damage the sample, and permit a three dimensional investigation of the surface.

  • Prognostic Factors The most important prognostic factor is the stage at the time of presentation. Fortunately, most melanomas are diagnosed in clinical stages I and II. The revised American Joint Committee on Cancer (AJCC) staging system for melanoma is based on microscopic primary tumor depth (Breslow's thickness), presence of ulceration, evidence of nodal involvement, and presence of metastatic disease to internal sites (Table 83-3). Certain anatomic sites may affect the prognosis.

  • Th ere is something about being human that instills in us a sense of wonder. When we stop to think about it, the very idea of life seems such a mystery. Where did we come from? How did life begin? When we look at the sky, we wonder about the vastness of the universe and whether other life may exist there. If we look through a microscope at a drop of pond water, we are amazed at the variety of tiny creatures we see. Since cells form the very basis of life, it is only natural that our sense of wonder extends to the cell. Where did...

  • Each of us is unique. Like snowflakes that look the same but under the microscope are different, we each have our own specialness that nobody else possesses. We have our own physical attributes, our own mental make-up, our own environmental background, and our own cultural inheritance. But more than all these, we have our own special, unique, and un-copiable talents. These talents are our gifts for life on earth. Some of us search in vain for their own special talents and never realize them fully before they die. Others come to them late in life after journeys that take them...

We thank Jack McIntosh for allowing us to organize a symposium in his honor. We also thank the participants of that symposium, most of whom authored chapters in this volume, for their excellent papers and patience throughout the process of bringing this book to publication. We especially thank Blake Edgar (UC Press) for initially supporting this project and his continual guidance throughout....
