Book Description
It is now 150 years ago, on 25th May 1842, that the son of a Salzburg ston emason presented a scientific work "On the coloured light of the double stars and certain other heavenly bodies" at a meeting of the Royal Bo hemian Society of Sciences held in Prague. Christian Andreas Doppler, then professor at the Prague Technical Institute, set a milestone in scien tific history in the meeting room of the Royal Society in the Charles Uni versity, just a few meters from the National Theatre where another genius from Salzburg, Wolfgang Amadeus Mozart, had celebrated his musical triumph with the premiere of his opera Don Giovanni fifty-five years earlier. Doppler's lecture set out in brilliant simplicity what we now call the Doppler principle, which since has found numerous uses in astronomy, which was of primary interest to Christian Doppler. In addition, it has found countless practical applications in physics, navigation, aeronautics, geodesy, medicine, science and technology. In medicine alone, Doppler sonography is now an established diagnostic procedure in the fields of childbirth, cardiology and diseases of the blood vessels, neurology, neuro surgery and vascular surgery, and is continually finding new medical appli cations in today's world of high technology.

Book Description
Galileo Unbound traces the journey that brought us from Galileo's law of free fall to today's geneticists measuring evolutionary drift, entangled quantum particles moving among many worlds, and our lives as trajectories traversing a health space with thousands of dimensions. Remarkably, common themes persist that predict the evolution of species as readily as the orbits of planets or the collapse of stars into black holes. This book tells the history of spaces of expanding dimension and increasing abstraction and how they continue today to give new insight into the physics of complex systems. Galileo published the first modern law of motion, the Law of Fall, that was ideal and simple, laying the foundation upon which Newton built the first theory of dynamics. Early in the twentieth century, geometry became the cause of motion rather than the result when Einstein envisioned the fabric of space-time warped by mass and energy, forcing light rays to bend past the Sun. Possibly more radical was Feynman's dilemma of quantum particles taking all paths at once — setting the stage for the modern fields of quantum field theory and quantum computing. Yet as concepts of motion have evolved, one thing has remained constant, the need to track ever more complex changes and to capture their essence, to find patterns in the chaos as we try to predict and control our world.

Book Description
Few specialties have a longer or richer eponymous background than obstetrics and gynaecology. Eponyms add a human side to an increasingly technical profession and represent the historic tradition and language of the speciality. This collection aims to perpetuate the names and contributions of pioneers and offer introductory profiles to the founders in whose steps we follow. This third edition includes 26 new entries, as well as expanded detail, illustration and quotation for existing entries. Biographical data and historical and medical context are discussed for each of the 391 names, with reference to 34 countries, reflecting the field's far reaching origins. More than 1700 original references feature, alongside an extensive bibliography of more than 2500 linked references to assist readers searching for more detailed information. This is a volume for physicians, midwives, medical historians, medical ethicists and all those interested in the history and evolution of obstetrical and gynaecological treatment.

Book Description
The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in Prague, is the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession. The relative changes in frequency can be explained as follows. When the source of the waves is moving toward the observer, each successive wave crest is emitted from a position closer to the observer than the previous wave. Therefore each wave takes slightly less time to reach the observer than the previous wave. Therefore the time between the arrival of successive wave crests at the observer is reduced, causing an increase in the frequency. While they are travelling, the distance between successive wave fronts is reduced; so the waves \\\\\\\"bunch together\\\\\\\". Conversely, if the source of waves is moving away from the observer, each wave is emitted from a position farther from the observer than the previous wave, so the arrival time between successive waves is increased, reducing the frequency. The distance between successive wave fronts is increased, so the waves "spread out". For waves that propagate in a medium, such as sound waves, the velocity of the observer and of the source is relative to the medium in which the waves are transmitted. The total Doppler Effect may therefore result from motion of the source, motion of the observer, or motion of the medium. Each of these effects is analyzed separately. For waves which do not require a medium, such as light or gravity in general relativity, only the relative difference in velocity between the observer and the source needs to be considered.

Book Description
This volume takes a look at the past – at the last 50 years in particular – and a look at the present, painting a picture of how the Imperial Royal Polytechnic Institute, founded in 1815, became the Technische Universität Wien – the "TU Wien" – with the launch of the 1975 University Organisation Act, and has increasingly developed into a research university ever since. Contemporaries from the years when the TU Wien was still the TH in Vienna have a place to tell their stories in this volume, alongside articles on interfaculty research facilities and service centres that support research activities and transfer of research results in accordance with the TU Wien's motto, “Technology for people”. One of the main goals of this book is to not only inform readers, but also to amuse them a bit as they peruse the pages of the volume.

Book Description
The Faculty of Technical Chemistry introduces itself! The historical development of Chemistry and Chemical Engineering at the TU is presented in the five chapters of this volume, starting with the foundation of the Imperial Royal Polytechnic Institute in 1815 and reaching all the way to the TU Wien in 2015, including current research highlights of the Faculty of Technical Chemistry and an overview of its modern equipment and building infrastructure, curricula, and excellent contact with the alumni. A lively picture of the teaching and research of this successful faculty and fully renovated Getreidemarkt Campus is painted, making, however, no claims to completeness.

Book Description
The European Physical Society Conference “Notions of Physics in Natural Philosophy” was held in 23-25 September 2007 in Athens. It was organized by the Program of History and Philosophy of Science of the Institute for Neohellenic Research / National Hellenic Research Foundation and the Laboratory of Science Education, Epistemology and Educational Technology of the University of Athens. The Conference was supported by the History of Physics Committee of the European Physical Society and the History of Physics Group of Institute of Physics (England). The latter was represented by Mr. Malcolm Cooper, editor of the Newsletter of the Group who kindly gave as a brief description of the activities of the Group. The main themes of the Conference were:  The emergence of notions of physics in ancient philosophy  The concept of physical laws in Philosophy of Nature during the Middle Ages and the Renaissance  The mathematization of Natural Philosophy and the emergence of classical sciences. We hope that the present volume of the Proceedings will be a useful tool for those interested on the subject.
