Heisenberg Werner Physics and Philosophy

Nobel Prize winner Werner Heisenberg's classic account explains the central ideas of the quantum revolution, and his celebrated Uncertainty Principle. Heisenberg reveals how words and concepts familiar in daily life can lose their meaning in the world of relativity and quantum physics. This in turn has profound philosophical implications for the nature of reality.

Nuclear Physics

From the Nobel Prize-winning physicist who developed the famous uncertainty principle, Nuclear Physics provides an in-depth look at the study of the atom. The book was compiled from a series of Heisenberg's lectures on the subject, and it is detailed and accessible enough for anyone interested in the subject. Heisenberg begins with a short history of atomic physics before delving into the theory of the processes and reactions within the atom. Nuclear Physics is an essential book to understanding the atom, giving readers an unparalleled look at nuclear physics from one of the greatest scientific minds of the twentieth century. A controversial WWII figure, Werner Heisenberg was a German physicist. Born in 1901 to an academic family, Heisenberg was interested in scientific and philosophical pursuits from a young age. After graduating from the University of Munich, where he studied under physicist Arthur Sommerfield, Heisenberg went on to establish a career in the study of atomic and particle theory. He won the Nobel Prize in 1932 for his Uncertainty Principle. Heisenberg was one of the top German scientists during World War II, and he worked as the director of the German Uranium Project developing an atomic bomb for Germany. He did not succeed in this effort, however, before the end of the war. He was incarcerated from 1945-46 for his role in the Nazi regime, but in the '50s and '60s, Heisenberg continued to contribute his research to the field of nuclear physics. He retired in 1970 and resided in Munich until his death in 1973. 0

Freud Sigmund General Introduction to Psychoanalysis

Sigmund Freud's controversial ideas have penetrated Western culture more deeply than those of any other psychologist. The 'Freudian slip', the 'Oedipus complex', 'childhood sexuality', 'libido', 'narcissism' 'penis envy', the 'castration complex', the 'id', the 'ego' and the 'superego', 'denial', 'repression', 'identification', 'projection', 'acting out', the 'pleasure principle', the 'reality principle', 'defence-mechanism' - are all taken for granted in our everyday vocabulary. Psychoanalysis was never just a method of treatment, rather a vision of the human condition which has continued to fascinate and provoke long after the death of its originator. Its central hypothesis, that we live in conflict with ourselves and seek to resolve matters by turning away from reality, did not emerge from experimental science but from self-examination and the unique opportunities for observation presented by the psychoanalytic technique - in particular, from the confessions produced by 'free-association' in Freud's consulting room. Written during the turmoil of the First World War, A General Introduction to Psychoanalysis was distilled from a series of lectures given at Vienna University, but had to wait for the war to end before being made available to the English speaking world.

Ким К., Карпова И. The electromagnetic acceleration of shells and missiles. Монография

The electrodynamic, electromagnetic and electrohydropulsive accelerating systems of objects are considered. The electrodynamic accelerators of electroconducting bodies are described. Their principle of action is based on the interaction of pulse magnetic field with currents induced in the accelerated body. To increase the pulse magnetic field we use the principle of electromagnetic cumulation of the initial magnetic field created by a superconducting coil. We give the concept of an electric acceleration of large objects having a weight of about 1000 kg till the speeds which are approaching to the space speeds. It is based on the combination of the conduction and induction principles of accelerating objects. It is shown that to increase the efficiency of a railgun we should divide the rail into separate electrically not connected segments and regenerate the energy of the magnetic field of a rail. We noticed in order to reduce losses in a rail it is reasonable to use the multilayered conductive mediums in the devices of current collection. For the induction accelerators with a continuous and step changing of the synchronous speed we consider a question about the control of inductor voltage at which the accelerator gets ideal properties. We investigated the question of the minimizing the length of a segmented accelerator. We consider the question of using the power characteristics of a spark discharge in liquid to accelerate the object.
