On What is History?' provides a student introduction to contemporary historiographical debates.
Carr and Elton are still the starting point for the vast majority of introductory courses on the nature of history. Building on his highly successful Rethinking History, Keith Jenkins explores in greater detail the influence of these key figures. He argues that historians need to move beyond their modernist' thinking and embrace the postmodern-type approaches of thinkers such as Richard Rorty and Hayden White.
Through its radical critique of Carr and Elton and its...

X-ray fluorescence (XRF) and x-ray diffraction (XRD) are analytical techniques used to identify substances by examining the amount of energy given off from a substance during an x-ray. The most common errors in XRF analysis and XRD usually occur during preparation of the specimen.

X-ray fluorescenct" spectrometry is now widely accepted as a highly versatile and potentially accurate method of instrumental elemental analysis and so it is somewhat surprising that although the volume of published work dealing with the technique is high the number of textbooks dealing exclusively with its application is relatively few. Without wishing to detract from the excellence of the textbooks which are already available we have both felt for some time, that a great need exists for a book dealing with the more practical aspects of the subject. For a number of years we have been...

The purpose of this book is to provide the reader with a series of work- ed examples in X -ray spectrometry and X -ray diffractometry, in such a way that each example can be treated either as a posed question, i. e. one to which the reader must himself provide an answer, or as a guide to the method of treating a similar problem. The latter, of course, also pro- vides a check on the answer produced by the reader. Although much basic theory can be derived by study of this work the first intention of the book is not to provide a source of basic theoretical knowledge in X -ray analy- sis. It is...
