Writer on Science. Charles Ray

A book for adolescent would-be engineers and technicians, full of monochrome photos and accurate descriptions of the latest inventions between the world wars. An appealing combination of gee-whiz excitement ('Driving the latest type of tube train', 'an office building that is all glass'), practical instruction ('how hydraulic buffers stop the train') and do-it-yourself experiments ('the home-made seismograph at work'). Genuinely motivational and accurate.
