In the last five years alone, the bit rate of commercial point-to-point links has grown from 2.5 Gb/s to 40 Gb/s-and that figure is expected to more than double over the next two years! Such astonishing progress can be both inspiring and frustrating for professionals who need to stay abreast of important new developments in the field. Now Fiber-Optic Communication Systems, Second Edition makes that job a little easier. Based on its author's exhaustive review of the past five years of published research in the field, this Second Edition, like its popular predecessor, provides an in-depth look at the state of the art in fiber-optic communication systems. While engineering aspects are discussed, the emphasis is on a physical understanding of this complex technology, from its basic concepts to the latest innovations. Thoroughly updated and expanded, Fiber-Optic Communication Systems, Second Edition: * Includes 30% more information, including four new chapters focusing on the latest lightwave systems R&D * Covers fundamental aspects of lightwave systems as well as a wide range of practical applications * Functions as both a graduate-level text and a professional reference * Features extensive references and chapter-end problem sets.

    When the seventh row of the periodic table of elements was completed in June 2016 with the addition of four final elements—nihonium, moscovium, tennessine, and oganesson—we at last could identify all the ingredients necessary to construct our world.In Elemental, chemist and science educator Tim James provides an informative, entertaining, and quirkily illustrated guide to the table that shows clearly how this abstract and seemingly jumbled graphic is relevant to our day-to-day lives.James tells the story of the periodic table from its ancient Greek roots, when you could count the number of elements humans were aware of on one hand, to the modern alchemists of the twentieth and twenty-first centuries who have used nuclear chemistry and physics to generate new elements and complete the periodic table. In addition to this, he answers questions such as: What is the chemical symbol for a human? What would happen if all of the elements were mixed together? Which liquid can teleport through walls? Why is the medieval dream of transmuting lead into gold now a reality?Whether you're studying the periodic table for the first time or are simply interested in the fundamental building blocks of the universe—from the core of the sun to the networks in your brain—Elemental is the perfect guide.

    Mass starvation, long predicted for the fast-growing population, was about to become a reality. A call went out to the world’s scientists to find a solution. This is the story of the two enormously gifted, fatally flawed men who found it: the brilliant, self-important Fritz Haber and the reclusive, alcoholic Carl Bosch. Together they discovered a way to make bread out of air, built city-sized factories, controlled world markets, and saved millions of lives. Their invention continues to feed us today; without it, more than two billion people would starve.But their epochal triumph came at a price we are still paying. The Haber-Bosch process was also used to make the gunpowder and high explosives that killed millions during the two world wars. Both men were vilified during their lives; both, disillusioned and disgraced, died tragically. Today we face the other un­intended consequences of their discovery—massive nitrogen pollution and a growing pandemic of obesity.The Alchemy of Air is the extraordinary, previously untold story of two master scientists who saved the world only to lose everything and of the unforseen results of a discovery that continues to shape our lives in the most fundamental and dramatic of ways.

     But taking that initial leap of faith is difficult when you’ve tumbled in the turmoil of your past and you know just how much it hurts to relive it. I get it. I’ve been there. I’ve made my fair share of mistakes when it comes to the dating department. And as far as I’m concerned, most men are complete assholes. So why should I waste my mine? It’ll always end the same. Or, at least, that’s what I kept telling myself as I kept my head down and focused on becoming a veterinarian. Forget them, I repeated over and over again. You don’t need them. How many times have you cried for them and they never shed a single tear for you? Maybe that voice in the back of my head had a point but what’s the point of living if you’re always on your own? Because, trust me, being alone sucks. And the constant silence of an empty apartment is a surefire way to insanity. So, why am I so opposed to Dr. Goodman? The dreamboat that fell out of the sky and practically landed on my lap due to a little airplane mix up. Because I’m afraid that he’s going to turn out like every other lowlife that’s ever shown their interest in me. And I’m not about to get my heart broken by a surgeon even if he knows how to stitch it back together again. I think I’ll just save myself the pain.

    The solved exercises cover all of the techniques discussed in the text, and include step-by-step instruction on working through the algorithms.
