Taschenbuch. Condizione: Neu. Neuware -In diesem Bandchen wird der Versuch gemacht, einem breiteren Leserkreis die Gedankengange und Ergebnisse einer Wissenschaft naherzubringen, die an der Grenze zwischen zwei alteren Schwe stern steht. Der Grund ist einfach der, daB diese Gedanken und Befunde von immer noch steigender Bedeutung fiir unser alIer Leben und Umgebung sind. Es wird deutlich werden, daB das meiste von dem, was die Chemie zur Umgestaltung unserer Welt beigetragen hat, nur durch die Untermauerung mit den Gesetzen der Physik moglich gewesen ist. Das Wesen der physikalischen Chemie ist namlich, die qualitativen Knderungen, die wir als chemische Reaktionen bezeichnen, quantitativ zu untersuchen und zu verstehen. Das setzt natiirlich bei dem schopferischen Forscher griindliche Kenntnisse der Chemie, aber auch der Physik und der Mathematik voraus, und alIes dies sind Hemmnisse flir eine ge meinverstandliche DarstelIung. Trotzdem solI der Versuch unternommen werden, mit einem Minimum von chemischen Stoffkenntnissen und chemischen Vor aussetzungen auszukommen und iiberdies nicht die mathematischen Entwicklungen darzustellen, die zu den Ergebnissen gefiihrt haben, sondern diese selbst, moglichst des Gewandes der Mathematik ent kleidet. Der Verfasser hofft, daB es ihm dabei gelungen ist, das recht eigenartige und ungewohnliche Gebaude der physikalischen Chemie dem gebildeten Laien verstandlich zu machen und zu zei gen, wie durch die beschriebene Durchdringung mehrerer Wissen schaften chemische Reaktionen in neuem Lichte erscheinen und weiterer Anwendung zum Wohl der Menschheit zuganglich ge worden sind.

This item is printed on demand - it takes 3-4 days longer - Neuware -of the cholecystogram. 1940 - the first anastomosis for oesophageal atresia by CAMERON HAIGHT in Ann Arbor and the first duodeno-pancreatectomy for pancreatic carcinoma, perfor med by WHIPPLE in New York. In 1943 - again WHIPPLE and his associates carried out the first porto-caval anastomosis at Columbia University and in 1945 - there followed BLALOCK'S anastomosis for Fallot's Tetralogy. In the following years the heart, as the last organ of the human body, became the chief target of surgical therapy. Most of the cardiovascular procedures, which today Fig. 4. New medical center of the Free University in West-Berlin under construction are part of the routine all over the world, originated in the United States or in Canada: in particular the spectacular successes of open heart surgery in hypothermia or extracorporeal circulation and the replacement of cardiac valves and arteries. This was the achievement of many active fellows of the American College of Surgeons with names well-known to all of us. The gradient between the surgical standards of our two countries was regrettably large after the second world war. The longtime isolation, the destruction of our cities, the loss of man-power through two world wars and the emigration following 1933 as well as a considerable brain-drain in more recent years were the main causes. 640 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present volume contains the edited proceedings of the Vth Symposium of the 'Gesellschaft fiir Nephrologie' held in Lausanne, Switzerland, from September 21 to September 23, 1967. The manuscripts were arranged according to their contents rather than to their titles. An attempt was made to divide the allotted space between different contributors according to the apparent importance or originality of the contributions. Most of the papers submitted were written in either German or a rather inarticulate English, and subsequently, have been translated into English by the editors and their collaborators. The editors are indebted to Mr. R. Darling, student of medicine of the Faculte de Medicine de l'Universite de Lausanne, for reviewing the English translation. Editing was limited to requirements based on form rather than on content. In a few instances, manuscripts which were inadequate in form were accepted because their contents appeared interesting or important. A very few manuscripts were either not submitted or could not be included in the present proceedings, because they did not satisfy the editorial standards. Some papers are published in the present proceedings in abstract form because they have been submitted elsewhere for full publication. The editors' responsibility does not extend to the factual content of the manuscripts. The editors wish to apologize for the long delay in publishing these proceedings, a delay which may be attributed to difficulties in communication and cooperation with various authors. 424 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -THE idea of collecting these essays occurred to me when, in the leisure of retire ment, I scanned some of my own books and found that two of the more widely read show a startling change of attitude to some of the fundamental concepts of science. These are Einstein's Theory of Relativity of 1921 and the American edition of The Restless Universe of 1951. I have taken the introduction of as the former the first item of this collection, the postscript to the latter as its last. These books agree in the relativistic concept of space and time, but differ in many other funda mental notions. In 1921 I believed-and I shared this belief with most of my contemporary physicists-that science produced an objective knowledge of the world, which is governed by deterministic laws. The scientific method seemed to me superior to other, more subjective ways of forming a picture of the world philosophy, poetry, and religion; and I even thought the unambiguous language of science to be a step towards a better understanding between human beings. In 1951 I believed in none of these things. The border between object and subject had been blurred, deterministic laws had been replaced by statistical ones, and although physicists understood one another well enough across all national frontiers they had contributed nothing to a better understanding of nations, but had helped in inventing and applying the most horrible weapons of destruction. 184 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The 1.5th of June, 1.966 marked the 25th anniversary of the death of OTFRID FOERSTER, one of those scientists who achieve international recognition in their younger years. He ranks among the greatest of the Gerrnan neurologists and he stands as a peer among the great narnes of the world responsible for the shaping of the image of Neurology: HUGHLINGS JACKSON, CHARCOT, DUCHENNE DE BOULOGNE, DEJERINE, ERB, Sir HENRY HEAD, MONAKow, and SHERRINGTON. As if possessed by ademon FOERSTER spent himself indefatigably to achieve his almost superhuman task during his lifetime. His work will remain a deterrninant for Neurology for a long time to come. Let his own publications speak for hirn. The epilogues, written shortly after his death, picture hirn more vividly than can be done today. A short biography and a number of memoirs introduce excerpts from his scientific presentations, many of which are intro duced by abrief prefatory note regarding the circumstances of the specific project. Our gratitude is extended to the Springer Publishing House for facilitating an English translation of the original Gerrnan edition prepared for the Joint Annual Meeting of the 'Gerrnan Society for Neurology' and the 'German Society for Internal Medicine', 1.966. And I should also like to express my gratitude to Dr. ADOLF ROSENAUER and Dr. JOSEPH EVANS for their translations. 124 pp. Englisch.
