    Widely accepted as the authoritative text and reference on electronic circuit design, both analog and digital, this book revolutionized the teaching of electronics by emphasizing the methods actually used by circuit designers -- a combination of some basic laws, rules of thumb, and a large bag of tricks. The result is a largely nonmathematical treatment that encourages circuit intuition, brainstorming, and simplified calculations of circuit values and performance. The new Art of Electronics retains the feeling of informality and easy access that helped make the first edition so successful and popular. It is an ideal first textbook on electronics for scientists and engineers and an indispensable reference for anyone, professional or amateur, who works with electronic circuits.

    In these pages both everyday riders and pros tell their stories of freak accidents, animal attacks, sabotage, idiotic decisions, eerie or unexplained incidents, and other jaw dropping, adrenalin-pumping calamities. These stories bring to life the strange things possibilities that await, once we step on the pedals of our road, mountain, or commuter bikes. A sampling of misadventures in this collection includes the stories of: the mountain biker who follows a bull and then gets gored by it; the twenty African Americans who pioneered cycle touring by completing a Transamerica ride in 1897, but wait - this story gets strange...; the large rat that leapt on top of a woman's bike and slapped her repeatedly with its tail; an inside-the-head narration by a professional racer as he rides a brutal race, and then gets humiliated in changing room afterwards; the recreational cyclist who accidentally rides deep into a prison yard; the computer programmer who crashes a stationary bike during his first spin class; the bike messenger who can't call it quits even after getting hit by eight cars; and, the man who carefully spreads out tacks on the route of an all female race in an attempt to get a date. These stories will make you wonder, drop you to the floor laughing and leave you shaking your head with disbelief.

    We easily get addicted to the high of achieving our goals. This isn't always a bad thing but it can be when we lose sight of the more important things in life.Many people never really feel satisfied in their regular day to day living and so they constantly strive for something outside of themselves to make up for their feelings of boredom, unworthiness, or whatever it may be.In our success-driven culture, it's very easy to miss out on the simple joys in life. Most people find it very difficult to be happy with a simple existence.First of all, there is nothing wrong with striving for bigger things. There is also nothing wrong with living a very simple and ordinary existence.What is truly important in the grand scheme of things is how we FEEL and how we make others feel, and this, believe it or not, has nothing to do with the outward circumstances of our lives.It costs absolutely nothing to be a kind and loving person. It costs nothing to focus on the brighter side of life. It's all a matter of perspective and our ability to release the negativity within ourselves.This book discusses a simple but powerful strategy for releasing these negative emotions that block us from experience the joy of the present moment. It shows you step by step how to be happy regardless of your life circumstances. It's easier than you think. Enjoy :)
