The New York Times Book of Science Questions & Answers

Why is glass transparent? Why do cats purr? Why do men have nipples? These are but a handful of the thousands of questions that over the years have been asked and answered in The New York Times "Science Q&A" column. At last, the best and most interesting questions-and their replies-have been collected in a book for general readers.

From wild animals to outdoor vegetation, from the human body to the heavens above, The New York Times Book of Science Questions and Answers takes readers on a thoroughly entertaining and informative journey through the world we live in. Like David Feldman's bestselling books Do Penguins Have Knees? and Why Do Clocks Run Clockwise?, this is science at its fun-filled best. Featuring answers from a wide variety of leaders across the country in scientific research and education, and illustrated by the delightful drawings of Victoria Roberts, The Times Q&A column is one of the best read features in the Science Times, which is one of the most popular sections of the newspaper. With a daily circulation of 1.2 million people, The New York Times is a leader in conveying scientific information to the general public.

This fact-filled handbook for the scientifically curious should prove invaluable as a family reference book, as a classroom resource, as an entertaining subway diversion, and even as a supplement to public libraries' Frequently Asked Questions lists.

Standard and Primary covers are widely available through general retailers. They often have higher print runs and can be cheaper, especially during sales.

In contrast, Direct Market (DM) and variant covers are primarily sold in comic shops. DM editions tend to have more limited availability and may be more valuable to collectors.

The main differences lie in artwork style, availability, price, and collector appeal. Ultimately, the choice between standard and variant covers depends on personal preference, budget, and individual collecting goals.
