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.

The present is a contest between the bright and dark sides of discovery. To avoid being torn apart by its stresses, we need to recognize the fact―and gain courage and wisdom from the past. Age of Discovery shows how.
Now is the best moment in history to be alive, but we have never felt more anxious or divided. Human health, aggregate wealth and education are flourishing. Scientific discovery is racing forward. But the same global flows of trade, capital, people and ideas that make gains possible for some people deliver big losses to others―and make us all more vulnerable to one another.
Business and science are working giant revolutions upon our societies, but our politics and institutions evolve at a much slower pace. That’s why, in a moment when everyone ought to be celebrating giant global gains, many of us are righteously angry at being left out and stressed about where we’re headed.
To make sense of present shocks, we need to step back and recognize: we’ve been here before. The first Renaissance, the time of Columbus, Copernicus, Gutenberg and others, likewise redrew all maps of the world, democratized communication and sparked a flourishing of creative achievement. But their world also grappled with the same dark side of rapid change: social division, political extremism, insecurity, pandemics and other unintended consequences of discovery.
Now is the second Renaissance. We can still flourish―if we learn from the first.
