Mechanical engineering including mechanical and chemical engineering. At its simplest, thermodynamics is the study of energy, its use and transformation through a system. Typically, engineering thermodynamics is concerned with changing energy from one form to another. As an example, automotive engines convert chemical energy (enthalpy) from the fuel into heat, and then into mechanical work that eventually turns the wheels. Thermodynamics principles are used by mechanical engineers in the fields of heat transfer, thermofluids, and energy conversion. Mechanical engineers use thermo-science to design engines and power plants, heating, ventilation, and air-conditioning (HVAC) systems, heat exchangers, heat sinks, radiators, refrigeration, insulation, and others.
Feathers: The Evolution of a Natural Miracle news magazine "Maclean's", Brian Bethune praised Hanson's storytelling, writing, "For all the intriguing science, what really livens up Hanson's passionate discussion of his 'natural miracle' are the stories he tells." Laurence A. Marschall, a physics professor at Gettysburg College, wrote in a review published in the magazine "Natural History", "In sum, "Feathers" is an impressive blend of beauty, form, and function." Frances C. James, in a review published in "The Condor", described the book as "scholarly and enjoyable", commenting that "Hanson has worked hard to summarize the science behind our current understanding of the form and function of feathers, their
