Book excerpt: This book, which will appeal to all with an interest in the history of radiology and physics, casts new light on the life and career of Wilhelm Conrad Röntgen, showing how his personality was shaped by his youth in the Netherlands and his teachers in Switzerland. Beyond this, it explores the technical developments relevant to the birth of radiology in the late nineteenth century and examines the impact of the discovery of X-rays on a broad range of scientific research. Röntgen (1845-1923) was born in Lennep, Germany, but emigrated with his family to the Netherlands in 1848. As a 17-year-old he moved to Utrecht, entering the Technical School and living at the home of Dr. Jan Willem Gunning. In this well-educated family he was stimulated to continue his studies at university. In 1868 he received a diploma from the Federal Polytechnic School in Zurich and just a year later completed a PhD in physics. He followed his mentor, August Kundt, to the universities of Würzburg (1870) and Strasburg (1872) and married Anna Ludwig in 1872. In 1879 Röntgen gained his first professorship at a German University, in Giessen, followed by a chair in Würzburg in 1888. Here he discovered X-rays in 1895, for which he received the first Nobel Prize in physics in 1901. From 1900 until his retirement in 1921 he occupied the chair of physics at the Munich University.
Download or read book A Century of X Rays and Radioactivity in Medicine written by R.F Mould and published by CRC Press. This book was released on 2018-02-06 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Century of X-Rays and Radioactivity in Medicine: With Emphasis on Photographic Records of the Early Years celebrates three great discoveries-x-rays (1895), radioactivity (1896), and radium (1898)-and recalls the pioneering achievements that founded the new science of radiology and changed the face of medicine forever. Over 700 historical illustrations with full and informative captions are supported by short introductory essays to illuminate the fascinating radiological past in an easy-to-read style. The focus of this book is on the historically more interesting early years of discovery, invention, diagnosis, therapy, dosimetry, risk, and protection. Interspersed with a variety of radiological anecdotes, the photographic record is complemented by archival accounts of the pioneer scientists and physicians and their early patients. In the chapters on diagnostic techniques, radiotherapy, and nuclear medicine, the author contrasts old methods with newer technologies. He also includes two fascinating chapters on museum and industrial applications of radiography. The book is comprehensively indexed for easy retrieval of the wide variety of people, techniques, apparatus, and examples featured throughout this radiological journey.
Download or read book Magick Without Tears written by Aleister Crowley and published by CreateSpace. This book was released on 2014-03-07 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book consists of 80 letters to various students of magick. Originally to be titled Aleister Explains Everything, the letters offer his insights into both magick and Thelema—-Crowley's religious and ethical system—-with a clarity and wit often absent in his earlier writings. The individual topics are widely varied, addressing the orders O.T.O. and AA, Qabalah, Thelemic morality, Yoga, astrology, various magical techniques, religion, death, spiritual visions, the Holy Guardian Angel, and other issues such as marriage, property, certainty, and meanness. The book is considered by many as perhaps Crowley's most notable contribution to the occult studies, defining magick for the 20th century.

Download or read book Screening the Body written by Lisa Cartwright and published by U of Minnesota Press. This book was released on 1995 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Moving images are used as diagnostic tools and locational devices every day in hospitals, clinics and laboratories. But how and when did such issues come to be established and accepted sources of knowledge about the body in medical culture? How are the specialized techniques and codes of these imaging techniques determined, and whose bodies are studied, diagnosed and treated with the help of optical recording devices? "Screening the Body" traces the unusual history of scientific film during the late 19th and early 20th centuries, presenting material that is at once disturbing and engrossing. Lisa Cartwright looks at films like "The Elephant Electrocution". She brings to light eccentric figures in the history of the science film such as William P. Spratling who used Biograph equipment and crews to film epileptic seizures, and Thomas Edison's lab assistants who performed x-ray experiments on their own bodies. Drawing on feminist film theory, cultural studies, the history of film, and the writings of Foucault, Lisa Cartwright illustrates how this scientific cinema was a part of a broader tendency in society toward the technological surveillance, management, and physical transformation of the individual body and the social body. She frequently points out the similarities of scientific film to works of avant-garde cinema, revealing historical ties among the science film, popular media culture and elite modernist art and film practices. Ultimately, Cartwright unveils an area of film culture that has rarely been discussed, but which will leave readers scouring video libraries in search of the films she describes.
Download or read book Brodmann s written by K. Brodmann and published by Springer Science & Business Media. This book was released on 2007-02-16 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the third edition of the translation, by Laurence Garey, of "Vergleichende Lokalisationslehre der Grosshirnrinde" by Korbinian Brodmann, originally published by Barth-Verlag in Leipzig in 1909. It is one of the major "classics" of the neurological world. Even today it forms the basis for so-called "localisation" of function in the cerebral cortex. Brodmann's "areas" are still used to designate functional regions in the cortex, the part of the brain that brings the world that surrounds us into consciousness, and which governs our responses to the world. For example, we use "area 4" for the "motor" cortex, with which we control our muscles, "area 17" for "visual" cortex, with which we see, and so on. This nomenclature is used by neurologists and neurosurgeons in the human context, as well as by experimentalists in various animals. Indeed, Brodmann's famous "maps" of the cerebral cortex of humans, monkeys and other mammals must be among the most commonly reproduced figures in neurobiological publishing. The most famous of all is that of the human brain. There can be few textbooks of neurology, neurophysiology or neuroanatomy in which Brodmann is not cited, and his concepts pervade most research publications on systematic neurobiology. In spite of this, few people have ever seen a copy of the 1909 monograph, and even fewer have actually read it! There had never been a complete English translation available until the first edition of the present translation of 1994, and the original book had been almost unavailable for 50 years or more, the few antiquarian copies still around commanding high prices. As Laurence Garey, too, used Brodmann’s findings and maps in his neurobiological work, and had the good fortune to have access to a copy of the book, he decided to read the complete text and soon discovered that this was much more than just a report of laboratory findings of a turn-of-the-twentieth-century neurologist. It was an account of neurobiological thinking at that time, covering aspects of comparative neuroanatomy, neurophysiology and neuropathology, as well as giving a fascinating insight into the complex relationships between European neurologists during the momentous times when the neuron theory was still new.

Available in PDF, EPUB and Kindle. Book excerpt: To perform my late promise to you, I shall without further ceremony acquaint you, that in the beginning of the Year 1666 (at which time I applyed my self to the grinding of Optick glasses of other figures than Spherical,) I procured me a Triangular glass-Prisme, to try therewith the celebrated Phænomena of Colours. And in order thereto having darkened my chamber, and made a small hole in my window-shuts, to let in a convenient quantity of the Suns light, I placed my Prisme at his entrance, that it might be thereby refracted to the opposite wall. It was at first a very pleasing divertisement, to view the vivid and intense colours produced thereby; but after a while applying my self to consider them more circumspectly, I became surprised to see them in an oblong form; which, according to the received laws of Refraction, I expected should have been circular. They were terminated at the sides with streight lines, but at the ends, the decay of light was so gradual, that it was difficult to determine justly, what was their figure; yet they seemed semicircular. Comparing the length of this coloured Spectrum with its breadth, I found it about five times greater; a disproportion so extravagant, that it excited me to a more then ordinary curiosity of examining, from whence it might proceed. I could scarce think, that the various Thickness of the glass, or the termination with shadow or darkness, could have any Influence on light to produce such an effect; yet I thought it not amiss, first to examine those circumstances, and so tryed, what would happen by transmitting light through parts of the glass of divers thicknesses, or through holes in the window of divers bignesses, or by setting the Prisme without so, that the light might pass through it, and be refracted before it was terminated by the hole: But I found none of those circumstances material. The fashion of the colours was in all these cases the same.
Download or read book Biologically Inspired Physics written by L. Peliti and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: The workshop "Biologically Inspired Physics" was organized, with the support of the NATO Scientific Affairs Division and the Directorate-General for Science, Research and Development of the Commission of the European Communities, in order to review some subjects of physics of condensed matter which are inspired by biological problems or deal with biological systems, but which address physical questions. The main topics discussed in the meeting were: 1. Macromolecules: In particular, proteins and nucleic acids. Special emphasis was placed on modelling protein folding, where analogies with disordered systems in con densed matter (glasses, spin glasses) were suggested. It is not clear at this point whether such analogies will help in solving the folding problem. Interesting problems in nucleic acids (in particular DNA) deal with the dynamics of semiflexible chains with torsion and the relationship between topology and local structure. They arise from such biological problems as DNA packing or supercoiling. 2. Membranes: This field has witnessed recent progress in the understanding of the statistical mechanics of fluctuating flexible sheets, such as lipid bilayers. It appears that one is close to understanding shape fluctuations in red blood cells on a molec ular basis. Open problems arise from phenomena such as budding or membrane fusion. Experiments on model systems, such as vesicle systems or artificial lipids, have great potential. Phenomena occurring inside the membrane (protein diffusion, ionic pumps) were only discussed briefly.

Download or read book Einstein on Race and Racism written by Fred Jerome and published by Rutgers University Press. This book was released on 2005-07-11 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nearly fifty years after his death, Albert Einstein remains one of America's foremost cultural icons. A thicket of materials, ranging from scholarly to popular, have been written, compiled, produced, and published about his life and his teachings. Among the ocean of Einsteinia-scientific monographs, biographies, anthologies, bibliographies, calendars, postcards, posters, and Hollywood films-however, there is a peculiar void when it comes to the connection that the brilliant scientist had with the African American community. Nowhere is there any mention of his close relationship with Paul Robeson, despite Einstein's close friendship with him, or W.E.B. Du Bois, despite Einstein's support for him. This unique volume is the first to bring together a wealth of writings by the scientist on the topic of race. Although his activism in this area is less well known than his efforts on behalf of international peace and scientific cooperation, Einstein spoke out vigorously against racism both in the United States and around the world. Fred Jerome and Rodger Taylor suggest that one explanation for this historical amnesia is that Einstein's biographers avoided "controversial" topics, such as his friendships with African Americans and his political activities, including his involvement as co-chair of an antilynching campaign, fearing that mention of these details may tarnish the feel-good impression his image lends topics of science, history, and America. Combining the scientist's letters, speeches, and articles with engaging narrative and historical discussions that place his public statements in the context of his life and times, this important collection not only brings attention to Einstein's antiracist public activities, but also provides insight into the complexities of antiracist culture in America. The volume also features a selection of candid interviews with African Americans who knew Einstein as children. For a man whose words and reflections have influenced so many, it is long overdue that Einstein's thoughts on this vital topic are made easily accessible to the general public.
