Biology: How Life Works was written in response to recent and exciting changes in biology, education, and technology with the goal of helping students to think like biologists. The text, visual program, and assessments were developed together to provide students with the best resources to gain an understanding of modern biology.
Content is selected carefully, is integrated to illustrate the connections between concepts, and follows six themes that are crucial to biology: the scientific method, chemical and physical principles, cells, evolution, ecological systems, and human impact.
The second edition continues this approach, but includes expanded coverage of ecology, new in-class activities to assist instructors in active teaching, new pedagogical support for visual synthesis maps, and expanded and improved assessment.

How Things Work: The Physics of Everyday Life, Binder Ready Version, 6th Edition provides an accessible introduction to physics for the non-science student. Like the previous editions it employs everyday objects, with which students are familiar, in case studies to explain the most essential physics concepts of day-to-day life. Lou Bloomfield takes seemingly highly complex devices and strips away the complexity to show how at their heart are simple physics ideas. Once these concepts are understood, they can be used to understand the behavior of many devices encountered in everyday life.

A trillion seconds is equal to 31,700 years.
A trillion inches is equal to 15,800,000 miles.
In other words, a trillion seconds ago, Stone Age man lived in caves, and mastodons roamed Europe and North America.
Or, a trillion-inch journey will carry you 600 times around the Earth, and leave more than enough distance to carry you to the moon and back.
And yet a good part of the chapters that follow ought to show you quite plainly that even a trillion can become a laughably small figure in the proper circumstances.
Isaac Asimov is curious about nearly everything, and he has made it his business to share whatever he learns with us—there are few people as good at it as he is.
ONLY A TRILLION is only one example of the range of his talents and the depth of his knowledge. These twelve essays are on such diverse subjects as life on other planets, the famous Thiotimoline—and The Goose That Laid The Golden Eggs…but you’re just going to have to buy this book to find out what he knows about that.
