Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This book presents a comprehensive mathematical approach for solving stochastic magnetic field problems. It discusses variability in material properties and geometry, with an emphasis on the preservation of structural physical and mathematical properties. It especially addresses uncertainties in the computer simulation of magnetic fields originating from the manufacturing process. Uncertainties are quantified by approximating a stochastic reformulation of the governing partial differential equation, demonstrating how statistics of physical quantities of interest, such as Fourier harmonics in accelerator magnets, can be used to achieve robust designs. The book covers a number of key methods and results such as: a stochastic model of the geometry and material properties of magnetic devices based on measurement data; a detailed description of numerical algorithms based on sensitivities or on a higher-order collocation; an analysis of convergence and efficiency; and the application of the developed model and algorithms to uncertainty quantification in the complex magnet systems used in particle accelerators.

This book explores the role of the biblical patriarch Abraham in the formation and use of authoritative texts in the Persian and Hellenistic periods. It reflects a conference session in 2009 focusing on Abraham as a figure of cultural memory in the literature of these periods. Cultural memory is the shared reproduction and recalling of what has been learned and retained. It also involves transformation and innovation. As a figure of memory, stories of Abraham served as guidelines for identity-formation and authoritative illustration of behaviour for the emerging Jewish communities.

Many believe that equality of opportunity will be achieved when the prospects of children no longer depend upon the wealth and education of their parents. The institution through which the link between child and parental prospects may be weakened is public education. Many also believe that democracy is the political institution that will bring about justice. This study, first published in 2006, asks whether democracy, modeled as competition between political parties that represent different interests in the polity, will result in educational funding policies that will, at least eventually, produce citizens who have equal capacities (human capital), thus breaking the link between family background and child prospects. In other words, will democracy engender, through the educational finance policies it produces, a state of equal opportunity in the long run?

This volume contains editions of 35 texts, which have been excavated nearly 100 years ago in the ancient Egyptian village of Karanis, and which were still waiting publication. As all texts written on papyrus from the Egyptian countryside, these texts give a new insight into the life of the people who dwelled in a typical village of the Roman period in Egypt. The texts show the cultural diversity of those who cohabitated, whether they had Greek or Egyptian names, whether their main gods were the crocodiles or Zeus. In the lives of all of them tax-paying played an important role, as well as caring for their cattle and fields, doing business, and fullfilling the obligations of the Roman government. In particular interesting is the personage of Socrates the tax-collector. Since the ruins of Karanis are still standing (and worth a visit) with two nearly intact temples from the period of the texts, a more complete image of village life emerges from texts and the archaeology behind them. Papyrologists welcome every newly published text as a further stone of the mosaic image that they try to create of the past.
