In 1889, a year after both he and Heinrich Hertz discovered electromagnetic waves and for the first time demonstrated the truth of Maxwell's great theory of the electromagnetic field, physicist Oliver Lodge (1851-1940) published his deepest reflections on the nature and meaning of electricity, how it originates, and its different manifestations. There had been great scientific advances - the work of Faraday and Maxwell, his own experiments and those of Hertz - and a revolution in technology. There were also puzzling questions. What is the connection between electricity and the ether that occupies space? How does electricity manifest itself in matter? Why does it come in fixed units? The discovery of the electron eight years later would offer crucial answers. Always lucid and direct, with a gift for making the difficult seem simple, Lodge engages the reader with his fascination for the subject, much as he did in his famous lectures.

In the 1860s, radio waves were predicted by James Clerk Maxwell in his work on electromagnetism. It took a further twenty years for the first experiments to produce a working demonstration. In this guide to radio technology, first published in 1925, eminent physicist Sir Oliver Lodge (1851-1940) provides a concise history of the development of the wireless radio, explains the theory behind it, and includes some practical tips for amateurs. Having lived through and contributed to the discovery, he explains the difficulty of the early experiments, which took place in a time when terms like 'frequency' and 'inductance', now taken for granted, did not exist in the scientific vocabulary. His first-hand account reveals the incredible efforts poured into the development of a revolutionary modern technology, rekindling the sense of wonder that once surrounded this strange new science.

A political and social reformer, Samuel Smiles (1812-1904) was also a noted biographer in the Victorian period, paying particular attention to engineers. His first biography was of George Stephenson (1781-1848), whom he met at the opening of the North Midland Railway in 1840. After Stephenson died, Smiles wrote a memoir of him for Eliza Cook's Journal. With the permission of Stephenson's son, Robert, this evolved into the first full biography of the great engineer, published in 1857 and reissued here in its revised third edition. This detailed and lively account of Stephenson's life, which proved very popular, charts his education and youth, his crucial contribution to the development of Britain's railways, and his relationships with many notables of the Victorian world. It remains of interest to the general reader as well as historians of engineering, transport and business.
