'MacFadden has led an extensive life in science, as a paleontologist, museum director, university department chair, and National Science Foundation staff member. His analyses of NSF history and policy changes from the agency's 1952 start through 2018 - and of many successes and failures of his own - will be invaluable to anyone seeking research funds from this important government entity. The book focuses on explaining NSF's poorly understood Broader Impacts requirement, and it is especially needed now, when only about one in ten applications to NSF for funding are successful.' Bruce Alberts, University of California, San Francisco; former President of the National Academy of Sciences
