Editorial Reviews

"This book is a straight-forward, well-written, concise piece that skillfully covers...the methodologies of science in relationship to the life sciences. I highly recommend it to anyone who teaches these courses and places an emphasis, where it belongs, on 'how science works.'" —The Quarterly Review of Biology

"Though it might seem impossible to compress such a range of topics into about 200 very readable pages, Jenkins succeeds in providing a survey that might be of equal interest both for the curious reader in search for a popular state of the art discussion of the nine mentioned topics and for the methodologically-minded scholar looking for an introduction to the beauty and perplexities of biomedical research." —Metapsychology
