KEY TOPICS: Coverage begins with an optional review of key concepts--such as properties of compound semiconductor, quantum mechanics, semiconductor statistics, carrier transport properties, optical processes, and junction theory--then progress gradually through more advanced topics. The Second Edition has been both updated and expanded to include the recent developments in the field.

    Simple langauge and systematic development of the subject matter. Emphasis on concepts and clear mathematical derivations

    With pedagogical use of second color, it covers devices in one place so that circuit characteristics are developed early.

    Includes all new multimedia and pedagogy to bring physical geography to a new audience. The new fourth edition of Introducing Physical Geography, focuses on both content and pedagogy.

    In this fast-paced investigation into the adrenaline-pumping world of NASCAR, a physicist with a passion uncovers what happens when the rubber hits the road and 800- horsepower vehicles compete at 190 miles per hour only inches from one another. Diandra Leslie-Pelecky reveals how and why drivers trust the engineering and science their teams literally build around them not only to get them across the finish line in first place, but also to keep them alive. Professor Leslie-Pelecky is a physicist in love with the sport’s beauty and power and is uniquely qualified to explain exactly how physics translates into winning races. Based on the author’s extensive access to race shops, pit crews, crew chiefs and mechanics, this book traces the life cycle of a race car from behind the scenes at top race shops to the track. The Physics of NASCAR takes readers right into the ultra competitive world of NASCAR, from the champion driver’s hot seat behind the detachable steering wheel to the New Zealander nicknamed Kiwi in charge of shocks for the No. 19 car. Diandra Leslie-Pelecky tells her story in terms anyone who drives a car--and maybe occasionally looks under the hood--can understand. How do drivers walk away from serious crashes? How can two cars travel faster together than either car can on its own? How do you dress for a 1800°F gasoline fire? In simple yet detailed, high-octane prose, this is the ultimate thrill ride for armchair speed demons, auto science buffs, and NASCAR fans at every level of interest. Readers, start your engines.

    Their conclusion stems from Svensmark's research which has shown the previously unsuspected role that cosmic rays play in creating clouds. During the last 100 years cosmic rays became scarcer because unusually vigorous action by the Sun batted away many of them. Fewer cosmic rays meant fewer clouds--and a warmer world. The theory, simply put here but explained in fascinating detail, emerges at a time of intense public and political concern about climate change. Motivated only by their concern that science must be trustworthy, Svensmark and Calder invite their readers to put aside their preconceptions about manmade global warming and look afresh at the role of Nature in this hottest of world issues.

    It has been reprinted in Ideas and Opinions, Crown Publishers, Inc. 1954, pp 36 - 40. It also appears in Einstein's book The World as I See It, Philosophical Library, New York, 1949, pp. 24 - 28.Everything that the human race has done and thought is concerned with the satisfaction of deeply felt needs and the assuagement of pain. One has to keep this constantly in mind if one wishes to understand spiritual movements and their development. Feeling and longing are the motive force behind all human endeavor and human creation, in however exalted a guise the latter may present themselves to us. Now what are the feelings and needs that have led men to religious thought and belief in the widest sense of the words? A little consideration will suffice to show us that the most varying emotions preside over the birth of religious thought and experience. With primitive man it is above all fear that evokes religious notions - fear of hunger, wild beasts, sickness, death. Since at this stage of existence understanding of causal connections is usually poorly developed, the human mind creates illusory beings more or less analogous to itself on whose wills and actions these fearful happenings depend. Thus one tries to secure the favor of these beings by carrying out actions and offering sacrifices which, according to the tradition handed down from generation to generation, propitiate them or make them well disposed toward a mortal. In this sense I am speaking of a religion of fear. This, though not created, is in an important degree stabilized by the formation of a special priestly caste which sets itself up as a mediator between the people and the beings they fear, and erects a hegemony on this basis. In many cases a leader or ruler or a privileged class whose position rests on other factors combines priestly functions with its secular authority in order to make the latter more secure; or the political rulers and the priestly caste make common cause in their own interests.

    Nor do you need to be a great scientist to appreciate the exciting discoveries and intriguing mysteries of our universe.

    The quantum world doesn't play by those rules. Daniel Rice is a government science investigator whose specialty is solving seemingly intractable problems through scientific inquiry.But Daniel's intellectual strength is sorely tested by the bizarre realities he finds in the quantum world. Extra dimensions of space trap the unwary, probability replaces cause and effect, and time isn't what anyone imagined. The other side of the mirror is a place full of dangers, but it's also somewhere a dedicated scientist can uncover secrets that connect humans with something greater. If you liked the authenticity of The Martian, the page-turning pace of Da Vinci Code, and the inspirational world views of Arthur C. Clarke and Carl Sagan, you'll love The Quantum Series. A mind-bending journey from the ultra-small to the vast stage of the Milky Way. Acclaim for The Quantum Series Awarded the indieBRAG Medallion for 2018"Dazzling tale of weird science" - Publisher's Weekly"I can't recall when I last enjoyed a hard science series as much as this one. The concepts were astounding, the characters were easily believable, and the action emotionally driven. Very hard to put down. It kept me reading half the night. You'll be thinking about the far out science ideas promulgated in this series for a long time." - Chuck Juzek"A great story, no hatred, no evil people trying to destroy others, just a wonderful adventure with a fantastic outcome." - Ric Mannen"Fermi's Paradox is finally explained." - PE Gwinn"An exciting plot that kept me glued to my chair instead of mowing the lawn." - PE Gwinn"Probably one of the most entertaining and intellectually stimulating stories I've read in a long time... and I read a LOT!" - Jason Blackford"Great story that proves the universe is indeed full of magic!" - Rand"The protagonists have an almost poetic underpinning that had me rooting for their success." - J. Kareski"BTW, all three books show respect and admiration for women scientists as well as men." - Robin C."Mr. Phillips is the only person who explained quantum physics to me in a way that was not only understandable but entertaining." - Edward L.
