Book Description
In the last few years there has been a revival of interest in the old idea that spacetime may have more than four dimensions, all but four having been curled up into a small circumference. In this view the various particles and interactions we see at ordinary energies arise from a simple, perhaps purely geometrical, theory in higher dimensions. This idea has profound implications for elementary particle physics and cosmology, and raises challenging problems of mathematics. These matters were the topic of the Second Jerusalem Winter School of Theoretical Physics.

Book Description
This booklet seeks to suggest ways in which funds can be better used for making safe water available to the poor by illustrating how drilling costs can be reduced without compromising water quality, water quantity, or the productive life of the borehole. These arguments are directed towards the rural water supply sector as a whole. Those directly addressed are primarily decision makers, government civil servants, planners and implementers of water projects who are not experts in drilling, as well as technical people, project leaders, technical aid personnel etc. This publication is neither a detailed drilling manual nor a methodology of drilling methods.

Book Description
The history of automobiles is not just the story of invention, manufacturing, and marketing; it is also a story of repair. Auto Mechanics opens the repair shop to historical study—for the first time—by tracing the emergence of a dirty, difficult, and important profession. Kevin L. Borg's study spans a century of automotive technology—from the horseless carriage of the late nineteenth century to the "check engine" light of the late twentieth. Drawing from a diverse body of source material, Borg explores how the mechanic’s occupation formed and evolved within the context of broad American fault lines of class, race, and gender and how vocational education entwined these tensions around the mechanic’s unique expertise. He further shows how aspects of the consumer rights and environmental movements, as well as the design of automotive electronics, reflected and challenged the social identity and expertise of the mechanic. In the history of the American auto mechanic, Borg finds the origins of a persistent anxiety that even today accompanies the prospect of taking one's car in for repair.

Book Description
Richard Carter weaves together the myriad of factors that need to come together to make rural water supply truly available to everyone. He concludes that ultimately, systemic change to the global web of injustice that divides this world into rich and poor may be the only way to address the underlying problem.
