The second edition of this popular student textbook presents an up-to-date and comprehensive introduction to the process and practice of teaching and learning science. It takes into account changes in science education since the first edition was published, including more recent curriculum reform.

Though science fiction and fantasy have existed as literary genres for well over a century, a working definition of the terms has yet to be determined. Ursula K. Le Guin, who emerged as a popular science fiction and fantasy writer in the 1960s, has not only witnessed, but also experienced first-hand the shifts and transformations of these increasingly popular genres. Delve into her fantastical worlds and investigate several of her famous works in this study ideal for high school and undergraduate students.

After 30 years of advice to eat low fat, the United States, followed closely by many other, mostly but not exclusively, industrialized nations, is witnessing an unprecedented epidemic increase in obesity and diabetes, to name just two.

The cost of these developments to the individual and to society is enormous, and the projected cost for the future staggering. It is evident that the increase in obesity and diabetes is strongly related to faulty nutrition.

Proper nutrition is probably the most effective and cost-effective prevention for these and many other diseases, including most cancers.

It should be clear to anyone by now that proper nutrition involves much more than having three meals a day. The written media abound with nutritional advice and information. Many books promote often extremely controversial guidelines for weight loss and better health. Frequently, articles and books are based on unproven assumptions, anecdotal evidence, or single scientific studies that seem to point in one or the other direction. The reader who tries to make sense of it all tends to be utterly confused.

Yet, even though nutritional science is relatively young, it is a hard science and many aspects have been thoroughly researched. Our knowledge of other aspects, such as the functions and effects of many secondary phytochemicals, or the multiple interactions between many body chemicals during nutrition-related metabolism, is evolving continually. Nutritional science is an interdisciplinary endeavor based on chemistry, biology, physiology, and anatomy, which are often hard to understand and even harder to present in a condensed, easy to assimilate fashion.

Bertrand Russell -- agnostic, pacifist, great humanitarian, and Nobel Prize laureate -- reviews in this volume the conflict between science and traditional religion during the last four centuries, and attempts to estimate the influence of present-day science upon present-day theology.
