The Search For Christian Doppler

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.

Stroke is one of the most important and most feared conditions known to man. The threat of stroke is important to all people. What could be more devastating than to lose the ability to speak, move a limb, stand, talk, see, read, feel write or even think? This book brings together ideas, events and advances – the stories – before and during the 20th Century through the accounts of global experts in the field, many of them having been first-hand witnesses to progress. Focusing on selected stories of stroke, this book offers a readable summary of the most dramatic and extensive changes in knowledge about stroke and in caring for stroke patients. Of interest to anyone interested in neurosciences and for physicians caring for stroke patients, this book informs on moving forward, by looking to how we got to where we are.

A finely drawn portrait of Einstein's sixteen months in Prague In the spring of 1911, Albert Einstein moved with his wife and two sons to Prague, the capital of Bohemia, where he accepted a post as a professor of theoretical physics. Though he intended to make Prague his home, he lived there for just sixteen months, an interlude that his biographies typically dismiss as a brief and inconsequential episode. Einstein in Bohemia is a spellbinding portrait of the city that touched Einstein's life in unexpected ways—and of the gifted young scientist who left his mark on the science, literature, and politics of Prague. Michael Gordin's narrative is a masterfully crafted account of a person encountering a particular place at a specific moment in time. Despite being heir to almost a millennium of history, Einstein's Prague was a relatively marginal city within the sprawling Austro-Hungarian Empire. Yet Prague, its history, and its multifaceted culture changed the trajectories of Einstein's personal and scientific life. It was here that his marriage unraveled, where he first began thinking seriously about his Jewish identity, and where he embarked on the project of general relativity. Prague was also where he formed lasting friendships with novelist Max Brod, Zionist intellectual Hugo Bergmann, physicist Philipp Frank, and other important figures. Einstein in Bohemia sheds light on this transformative period of Einstein's life and career, and brings vividly to life a beguiling city in the last years of the Austro-Hungarian Empire.
