Charles Wheatstone began his life-long involvement with electrical engineering in the days when it was still at the stage of 'philosophical toys', yet he had a vision of telecommunications that could deliver printed messages around the world. With W.E. Cooke he developed the first practical electric telegraph. The problems of operating telegraphs over long distances led him into the field of electrical measurements. Wheatstone was a major figure in Victorian science, making contributions in the fields of optics and acoustics as well as electrical engineering. He had an encyclopaedic knowledge of the scientific literature in several languages, and made connections which benefited not only his own work but also that of others. His research aided the development of the new King's College London into a centre of scientific excellence. He invented the concertina and the stereoscope, both very popular in the nineteenth century. He is usually remembered for the Wheatstone Bridge, which he did not invent but publicised in the course of a lecture on measurements. His early attempts to measure the speed of an electric current were inconclusive, but his later studies of signals in submarine cables contributed to the understanding of the effect of capacitance and inductance in cables. He made electric motors, including a linear motor. In his lifetime there was insufficient electric power to exploit them, but his self-excited generator indicated the way ahead. This fascinating biography celebrates the bicentenary of Wheatstone's birth, and draws on information about the family business as well as letters, including correspondence with Cooke and Faraday, which were not available for the first edition, published by HMSO for the Science Museum in 1975
Sound Authorities shows how experiences of music and sound played a crucial role in nineteenth-century scientific inquiry in Britain. In Sound Authorities, Edward J. Gillin focuses on hearing and aurality in Victorian Britain, claiming that the development of the natural sciences in this era cannot be understood without attending to the study of sound and music. During this time, scientific practitioners attempted to fashion themselves as authorities on sonorous phenomena, coming into conflict with traditional musical elites as well as religious bodies. Gillin pays attention to sound in both musical and nonmusical contexts, specifically the cacophony of British industrialization. Sound Authorities begins with the place of acoustics in early nineteenth-century London, examining scientific exhibitions, lectures, spectacles, workshops, laboratories, and showrooms. He goes on to explore how mathematicians mobilized sound in their understanding of natural laws and their vision of a harmonious ordered universe. In closing, Gillin delves into the era’s religious and metaphysical debates over the place of music (and humanity) in nature, the relationship between music and the divine, and the tensions between spiritualist understandings of sound and scientific ones.
