    Clear Science Teaching to Set the Stage for an Awe-Inspiring Course Created for a lay audience and readily accessible, in this course science always takes precedence over drama. The lectures are certainly entertaining, often funny, even awe-inspiring at times, as befits the subject matter. Even though you will be entertained, you will be learning good science. Clear introductions to essential principles of physics support these lectures, including density, quantum theory, gravity, and the General Theory of Relativity. Professor Neil deGrasse Tyson also includes forays into disciplines such as chemistry and biology as needed to explain events in astronomy. For example, Dr. Tyson begins one lecture at a point 13 billion years ago, when all space, matter, and energy in the known universe were contained in a volume less than one-trillionth the size of a pinpoint-about the size of a single atom. By the time he finishes, the cosmos has been stretched, the planets and our Earth formed, and 70 percent of existing Earth species have been wiped out by a gigantic asteroidclearing the way for the evolution of humanity. Along the way he has touched on Einstein's famous equation, E=mc2; on the four forces that were once unified in the early cosmos in a way physicists are still trying to explain; and on the chemical enrichment of the universe by exploding supernovae, which give the universe its necessary supply of heavier elements including oxygen, nitrogen, iron and, most important, carbon. Carbon, we learn, is a "sticky" atom, capable of making more kinds of molecules than all other elements combined. It's the ideal element with which to experiment in the building of life forms and is, of course, the element responsible for the remarkable diversity of life, including us. As Dr. Tyson notes, we are made of stardust, just as the planets are. And he has created a course that explains exactly how that came to be, beginning with a grounding in the basic "machinery" of matter, forces, and energy that has been discovered on Earth and which also reveals itself throughout the universe. The Stark and Violent Beauty of the Universe With this basic foundation in place, explanations of cosmic events fall logically into place, and the realities of the universe-including its eventual demise-are revealed in stark and often violent beauty. You learn: how Saturn's rings were formed, and why they will eventually be lost why low-density conditions are necessary to produce the drama of the northern and southern auroras why even the most jagged and wild of the Earth's mountain ranges are, from a cosmic standpoint, really part of a perfectly smooth sphere how black holes are formed and the extraordinary way in which they can wreak havoc in the universe how asteroids moving through space represent threats of extraordinary consequence to Earth, no matter how long those threats may take to be realized why the seemingly infinite panorama of celestial bodies revealed by the Hubble Space Telescope's famous "Deep Field" so intrigued astronomers how astronomers actually look for new planets, why the odds seem overwhelmingly in favor of some kind of life out there, whether we ever make contact or not. Most important, none of these ideas are presented as isolated "space factoids" that serve no purpose but to entertain. They are there to illustrate and reinforce the key principles of physics and astrophysics that are continually being presented in this course. But the inclusion of real science doesn't prevent Dr. Tyson from having some fun, either. When it's time to show how a black hole might remove one from the universe, he leads you right up to the "event horizon" and slips you in-feet first. Since the event horizon represents the point within which nothing, not even light, can escape, you might think this is a bad idea. And you would be right. But as you plummet toward the "singularity" at the heart of the black hole, you will learn firsthand about the interesting effects of gravity truly unleashed, including what physicists refer to, with a straight face, as "spaghettification." (Actually, Professor Tyson recommends that you be sucked in to a large black hole rather than a small one. You'll still be spaghettified, but it won't happen as quickly.) But make no mistake: Dr. Tyson does not consider the cosmos a laughing matter, this kind of whimsical touch notwithstanding. In spite of his training, he remains, admittedly, still in awe of his subject. And he has created a course that might well produce the same feeling in you.

    Five hundred years after Luther’s now famous Ninety-five Theses appeared, Eric Metaxas, acclaimed biographer of the bestselling Bonhoeffer: Pastor, Martyr, Prophet, Spy and Amazing Grace: William Wilberforce and the Heroic Campaign to End Slavery, paints a startling portrait of the wild figure whose adamantine faith cracked the edifice of Western Christendom and dragged medieval Europe into the future. Written in riveting prose and impeccably researched, Martin Luther tells the searing tale of a humble man who, by bringing ugly truths to the highest seats of power, caused the explosion whose sound is still ringing in our ears. Luther’s monumental faith and courage gave birth to the ideals of liberty, equality, and individualism that today lie at the heart of all modern life.

    Inside a survey of world history's greatest trials are the key insights to critical issues we still talk about today, including freedom of speech, the death penalty, religious freedom, and the meaning of equality.Join Professor Linder for these 24 lectures that investigate important legal cases from around the world and across the centuries. From the trials of Socrates in ancient Athens and Thomas More in Henry VIII's England to the Nuremburg Trials in the wake of World War II and the media frenzy of the O. J. Simpson murder case, you'll discover what each of these trials has to teach us about ourselves and our civilization.Professor Linder takes you back in time to revisit some of history's most famous trials from fresh perspectives that ground them in the evolution of human ideas of law and justice, including the Salem Witch Trials, and the Scopes "Monkey" Trial. You'll also encounter less familiar (but equally important) legal battles, including medieval trials by ordeal and the Trial of Giordano Bruno, which would impact the later trial of Galileo.For years, Professor Linder has studied the fascinating intersection between history and jurisprudence. Now he's crafted these lectures to share that fascination with you.

    A leather couch. A neatly bearded, scholarly looking gentleman seated off to the side, only rarely speaking, quietly taking notes and occasionally nodding as the couch's supine occupant tells his or her story.In some ways, such a picture would indeed be accurate, a confirmation not only of the importance of Sigmund Freud in the history of psychology but also of the degree Freud dominates the popular perception of this discipline.But the picture would be inaccurate, as well.Freud was a physician, and the majority of psychologists are not. Both the psychoanalytic theory he pioneered and the therapeutic approach it was based onpsychoanalysishave seen their dominance wane in recent years. And psychologists today, as indebted as they may be to Freud's landmark explorations of our psychological landscape, are involved in far more than helping people cope with inner demons.The expansive and varied roles of contemporary psychologists create another common imageof a crowd of white-coated researchers gathered around a maze, carefully recording a white rat's performance. It's another inadequate picture because experimental psychologists today usually work with people, not animals.Moreover, the areas of interest those psychologists are pursuing now encompass every part of the process we use to develop and function as people:How we perceive, remember, and learnHow we select our friends and partners and retain their affection and loveThe things that motivate us as we make our choices in lifeEven how we relate to the vehicles, machinery, computer systems, or workspaces we encounter as we make our livings.
