"Matteo Lane is a liar. In the pages of Your Pasta Sucks, he repeats that he has no business writing a cookbook, all while masterfully (and hilariously) weaving an intricate tale of food and family and schooling the reader in the flavors, traditions, and techniques of Rome, Sicily, and his own Italian-American kitchen."—Katie Parla, author of Food of the Italian Islands

X-Ray ?uorescence analysis (XRF) has developed into a well-established multi-elemental analysis technique with a very wide ?eld of practical app- cations, especially those requiring nondestructive analytical methods. Over a long period of time, steady progress of XRF was made, both methodological and instrumental. Within the last decade, however, advancements in te- nology, software development, and methodologies for quanti?cation have p- vided an impetus to XRF research and application, leading to striking new improvements. The recent technological advances, including table-top inst- ments that take advantage of novel low-power micro-focus tubes, novel X-ray optics and detectors, as well as simpli?ed access to synchrotron radiation, have made it possible to extend XRF to low Z elements and to obtain t- and three-dimensional information from a sample on a micrometer-scale. The development of portable and hand-held devices has enabled a more ?exible use of XRF in a variety of new situations, such as archaeometry and process control. Furthermore, synchrotron radiation provides high excitation ?ux and even speciation capabilities due to energetically tunable radiation. Because of these recent advancements, the editors decided to compile a practical handbook of XRF as are source for scientists and industrial user sthat provides enough information to conceive and set up modern XRF experiments for use in awide range of practical applications. Additionally,selected sections consist of a concise summary of background information for readers who wish to gain a more in-depth understanding of the topics without conducting a lengthy search of the literature. The present handbook is not intended to be a textbook with interdependent chapters, rather a reference in which the information in each sectionis largely self-contained.

It is a pleasure and an honor to offer a few words of forward to Brian Warner's guide to photometry. In his preface, he makes a considerable point about amateurs and professionals, and those who dare or deign to step across the line supposedly dividing the two. Here I would like to make a few observations about the two monikers, and suggest that there is not, or at least should not be, a distinction - tween "amateur" and "professional. " In preparing these remarks I referred to W- ster’s New Collegiate Dictionary (1960 edition; not so new anymore, but that was when my collegiate experience began): am´a·teur, n. [F. , fr. L. amator lover, fr. amare to love. ] 1. One who cultivates a particular pursuit, study, or science, from taste, without pursuing it professionally; also, a dabbler. 2. In sports and esp. athletics, one who is not rated as a professional. Well. . . a "dabbler" eh? "not rated as a professional"? No wonder we have an identity problem here. Somehow in my youth as an amateur astronomer I missed this connotation of the term. To me, the meaning of the term amateur was do- nated by its root, "to love," that is, one who does what he does out of love of the subject, not for remuneration (to the extent one can get away with that).
