The first in the Focus Series on Global Science Education, The Whys of a Scientific Life examines why scientists do what they do. Working from a diverse background in scientific research, including academic departments of physics and chemistry, as well as the scientific civil service, the author describes the choices scientists make. Fundamentally, a scientist asks questions based on curiosity. In addition, the environment is very important. By influencing their elected governments, society itself shapes the scientific research that is undertaken by scientists. This book follows on naturally from the author’s last book, Skills for a Scientific Life, which is a how-to guide for scientists and those that aspire to engage in science as a career.
