Using brain power you never knew you had [emotional intelligence]

Engineering is a hard science, 'hard' meaning relying on scientific and mathematical principles. Is there room for the soft science of psychology, 'soft' meaning the people skills, such as communication, teamworking and emotional intelligence? The author describes what is meant by emotional intelligence and then explains how to use psychological skills at work by using the example of the problems with the water supply and sewage system in London in the mid-1850s.
