Download After the Breakthrough: The Emergence of High-Temperature by Helga Nowotny PDF

By Helga Nowotny

The invention of high-temperature superconductivity was once hailed as an enormous medical leap forward, inducing an exceptional wave of pleasure and expectation one of the clinical group and within the overseas press. This publication units this learn leap forward in context, and reconstructs the historical past of the invention. The authors research the emergence of this new study box and how its improvement was once formed by way of scientists and technological know-how coverage makers. additionally they research a number of the institutional and nationwide settings during which the study was once undertaken in addition to contemplating the clinical backgrounds and motivations of researchers who entered the sector following the unique discovery.

Fractal concepts in surface growth

Fractals and surfaces are of the main widely-studied components of contemporary physics. actually, so much surfaces in nature are fractals. during this booklet, Drs. Barabási and Stanley clarify how fractals will be effectively used to explain and are expecting the morphology of floor progress. The authors start by way of providing uncomplicated progress types and the foundations used to increase them.

Mathematical Theory of Elasticity of Quasicrystals and Its Applications

This interdisciplinary paintings on condensed topic physics, the continuum mechanics of novel fabrics, and partial differential equations, discusses the mathematical idea of elasticity and hydrodynamics of quasicrystals, in addition to its functions. by way of constructing new partial differential equations of upper order and their options less than complex boundary price and preliminary worth stipulations, the theories constructed the following dramatically simplify the answer of advanced elasticity difficulties.

Dirac Matter

This 15th quantity of the Poincare Seminar sequence, Dirac topic, describes the remarkable resurgence, as a low-energy potent idea of undertaking electrons in lots of condensed topic structures, together with graphene and topological insulators, of the recognized equation initially invented via P. A. M. Dirac for relativistic quantummechanics.

Liquifiers, refrigerators, and cryostats developed for physical and medical applications are now so efficient and reliable that some HTS materials may be used - not because they have higher critical temperatures, but due to other good qualities - alongside LTS at liquid helium temperatures. 24 The context of the discovery technological optimism for LTS does not seem completely unfounded. It did not ignore technical, economic, and political constraints, but assumed they could be overcome. The success of LTS as a contingent technology depended on the future of the systems and programs utilizing it - which looked bright at the time.

Everyone wanted to get in on the ground floor of any emerging applications. A kind of gold fever had broken out in the research community; after years of disillusionment, unfounded reports, and stagnation, suddenly it was again possible to "do physics" and to dream of superconductivity at room temperature. Through its intense media coverage, superconductivity had also captured the public interest. It was described as the scientificfindingwhose technological applications would sooner or later transform everyone's daily lives.

The BCS theory attracted considerable media interest: the New York Times heralded it with the headline "The Discovery of a Superconducting Alloy at Room Temperature is now Imminent" (Ortoli & Klein, 1989:1957). The BCS theory helped scientists understand why there are two types of superconductors - but did not predict what material would fall into which category, nor did it provide a clue for finding better superconductors. It was not without predictive power, though, having led to the discovery of coherence phenomena such as the Josephson effect.
