The Spectrum

Ever since the boom of spectrum analysis in the 1860s, spectroscopy has become one of the most fruitful research technologies in analytic chemistry, physics, astronomy, and other sciences. This book is the first in-depth study of the ways in which various types of spectra, especially the sun's Fraunhofer lines, have been recorded, displayed, and interpreted. The book assesses the virtues and pitfalls of various types of depictions, including hand sketches, woodcuts, engravings, lithographs and, from the late 1870s onwards, photomechanical reproductions. The material of a 19th-century engraver or lithographer, the daily research practice of a spectroscopist in the laboratory, or a student's use of spectrum posters in the classroom, all are looked at and documented here. For pioneers of photography such as John Herschel or Hermann Wilhelm Vogel, the spectrum even served as a prime test object for gauging the color sensitivity of their processes. This is a broad, contextual portrayal of the visual culture of spectroscopy in the 19th and early 20th centuries. The illustrations are not confined to spectra--they show instruments, laboratories, people at work, and plates of printing manuals. The result is a multifacetted description, focusing on the period from Fraunhofer up to the beginning of Bohr's quantum theory. A great deal of new and fascinating material from two dozen archives has been included. A must for anyone interested in the history of modern science or in research practice using visual representations.

Autism spectrum disorder (ASD) presents itself in many different ways, and teachers must be able to identify individual and shared characteristics to provide proper support. This can often present problems for teachers who lack experience of working with children across the entire spectrum, which ranges from supporting those with severe learning difficulties to working with highly able young people. Using real-life examples from their decades of experience, Francine Brower and Keith MacKenzie Cox explain how to identify diverse characteristics of autism and explore key challenges that individuals and schools face. With an emphasis on practical solutions, they offer a wealth of creative strategies and interventions perfect for any setting, from tapping into special interests and establishing routines to developing social skills. Covering a range of autism presentations, including sensory differences, communication, behaviour and socialisation, this is the ideal book for mainstream and special school teachers looking to improve their special educational needs provision, and develop the best possible learning outcomes for all pupils on the autism spectrum.

One morning she wakes to find herself in London, living in a rented room - but she has no memory of who she is or how she came to be there. Out of the fragments of another existence, she pieces together the facts: she is Diana Clouston, aged nineteen, holidaying in England from New Zealand, and soon to be married to a man she cannot remember. But all her memories seem to be of another world, a tepid, bleached-out place.
