Magnetic reconnection in flux-tubes undergoing spinning footpoint motions

Aims. Photospheric motions acting on the coronal magnetic field have the potential to build up huge amounts of magnetic energy. The energy may be released through magnetic reconnection, and so a detailed understanding of the 3D process is crucial if its implications for coronal heating are to be fully addressed. Methods. A 3D MHD experiment is described in which misaligned magnetic flux tubes are subjected to simple spinning boundary motions. Results. The resulting shear between adjacent flux systems generates a twisted central separator current sheet that extends vertically throughout the domain. Current density is amplified to a sufficient extent that reconnection begins, and occurs everywhere along the separator current sheet, while the separatrix current sheets that exist in the early stages of the experiment are found to be unimportant in the systems dynamical evolution. In 2D cross-sections, the reconnection process exhibits many similarities to the regime of flux pile-up reconnection

My Greatest Benefactions

This occasion is a cause for me to relax the natural modesty that has otherwise restrained me from describing these accomplishments more widely. I am one of the greatest benefactors of the University of Puget Sound School of Law. I did not comment when the new Law Center Building was named after Mr. Norton Clapp, nor did I resent it. Mr. Clapp is a generous and dedicated man, and he well deserves each of the many honors that have been bestowed upon him. Nevertheless, as will soon be very evident, the appropriate name for the Center was a much closer question than has ever been publicly admitted. I claim entire credit for introducing Fred Tausend to the University of Puget Sound School of Law. I was a mere Assistant Professor at the Law School at the time. I had been invited on leave to the University of Chicago Law School and, presumably, as a reward for my achievement, was instructed that if I wanted the leave, I would have to find a replacement for my Antitrust class

The Growth of Interdisciplinary Research and the Industrial Structure of the Production of Legal Ideas: A Reply to Judge Edwards

This brief response will attempt to repair these various deficiencies, though only in part because of the difficulty of the subject. It will try to explain more fully the rise of interdisciplinary legal research and will sketch the broader structure of the production and dissemination of new ideas about law and the legal system. The relationship between legal education and legal practice implicates an understanding of the market for legal ideas. To describe ideas as the subject of a market, of course, has become conventional. In my view, however, the market metaphor most typically distorts our understanding of the issue, because few of the typical characteristics of economic markets are present in the dissemination of ideas. This essay will try to approach a description of a market, nevertheless, by illustrating similarities between the production of legal ideas within law schools and the bar and the production of intellectual property in more familiar industrial contexts. The description will be far from comprehensive, but it will suggest that the alleged disjunction between legal education and practice, the focus of Judge Edwards\u27 essay as well as of my own earlier writing, does not adequately account for the broader process at work. The essay will also suggest that many of the developments in modern legal education that Judge Edwards so severely criticizes11 actually support, rather than conflict with, the broader values that he espouses

A Principled Approach Toward Insurance Law: The Economics of Insurance and the Current Restatement Project

The American Law Institute ( ALI ) initiated a project in 2010 to propose the Principles of the Law of Liability Insurance ( Principles ). A Principles project by the ALI is different from a Restatement of Law, for which the ALI is better known. A Restatement seeks to restate the common law of the fifty U.S. jurisdictions in systematized form. The ALI was organized many decades ago to achieve this ambition, in particular to counter the criticism that varying common law principles in the many different states in the U.S. made the law confused and contradictory across the states. The ALI has been successful and has published many volumes of Restatements over the succeeding years, generally disproving this point. A Principles project of the ALI is different. A Principles project proposes to state the law as it should be, presumably as discussion material or talking points for lawyers and academics to address over some time in the future
