Book Synopsis Uneasy Genius: The Life And Work Of Pierre Duhem by : St.L. Jaki
Download or read book Uneasy Genius: The Life And Work Of Pierre Duhem written by St.L. Jaki. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: A hundred years have now gone by since in the midsummer of 1882 Pierre Duhem, a graduate of College Stanislas, completed with brilliant success his entrance exams to the Ecole Normale Superieure and embarked on his career as a theoretical physicist. His father, a textile salesman, hoped that Hierre would pursue a career in business, one of the few professional fields where perhaps he would not have succeeded. Not that young Duhem lacked sense for the practical. He could have easily made a name for himself as an artist had he developed professionally his skill to draw portraits and landscapes. His ability to make a point and his readiness to join in a debate, could have earned him fame as a lawyer. A potential actor was in sight when he entertained friends with mimicry. That as a student of physics he entered and stayed first in his class at the Ecole Normale, did not thwart his talents for the life sciences. No less a biologist than Pasteur tried to obtain Duhem for assistant. His command of Greek and Latin would have secured him a career as a classicist. He was a Frenchman, not to be met too often, whose rightful ad miration for and mastery of his native tongue, did not prove a barrier to the major modern languages. As one who taught himself the complex art of medieval paleo graphy, he could easily have mastered the many auxiliary sciences needed by a consummate historian.

Book Synopsis Mechanical Systems, Classical Models by : Petre P. Teodorescu
Download or read book Mechanical Systems, Classical Models written by Petre P. Teodorescu. This book was released on 2008-09-24. Available in PDF, EPUB and Kindle. Book excerpt: As it was already seen in the first volume of the present book, its guideline is precisely the mathematical model of mechanics. The classical models which we refer to are in fact models based on the Newtonian model of mechanics, on its five principles, i. e. : the inertia, the forces action, the action and reaction, the parallelogram and the initial conditions principle, respectively. Other models, e. g. , the model of attraction forces between the particles of a discrete mechanical system, are part of the considered Newtonian model. Kepler’s laws brilliantly verify this model in case of velocities much smaller than the light velocity in vacuum. The non-classical models are relativistic and quantic. Mechanics has as object of study mechanical systems. The first volume of this book dealt with particle dynamics. The present one deals with discrete mechanical systems for particles in a number greater than the unity, as well as with continuous mechanical systems. We put in evidence the difference between these models, as well as the specificity of the corresponding studies; the generality of the proofs and of the corresponding computations yields a common form of the obtained mechanical results for both discrete and continuous systems. We mention the thoroughness by which the dynamics of the rigid solid with a fixed point has been presented. The discrete or continuous mechanical systems can be non-deformable (e. g.
