With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.

    On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time.A century later, another group of astronomers is performing a similar experiment on a much larger scale. The Event Horizon Telescope, a globe-spanning array of radio dishes, is examining space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. As Ron Cowen recounts, the foremost goal of the experiment is to determine whether Einstein was right on the details. Gravity lies at the heart of what we don't know about quantum mechanics, but tantalizing possibilities for deeper insight are offered by black holes. By observing starlight wrapping around Sagittarius A*, the telescope will not only provide the first direct view of an event horizon--a black hole's point of no return--but will also enable scientists to test Einstein's theory under the most extreme conditions.Gravity's Century shows how we got from the pivotal observations of the 1919 eclipse to the Event Horizon Telescope, and what is at stake today. Breaking down the physics in clear and approachable language, Cowen makes vivid how the quest to understand gravity is really the quest to comprehend the universe.

    Yet, as a species, humans have lost the ability to breathe correctly, with grave consequences.Journalist James Nestor travels the world to figure out what went wrong and how to fix it. The answers aren't found in pulmonology labs, as we might expect, but in the muddy digs of ancient burial sites, secret Soviet facilities, New Jersey choir schools, and the smoggy streets of Sao Paulo. Nestor tracks down men and women exploring the hidden science behind ancient breathing practices like Pranayama, Sudarshan Kriya, and Tummo and teams up with pulmonary tinkerers to scientifically test long-held beliefs about how we breathe.Modern research is showing us that making even slight adjustments to the way we inhale and exhale can jump-start athletic performance; rejuvenate internal organs; halt snoring, asthma, and autoimmune disease; and even straighten scoliotic spines. None of this should be possible, and yet it is.Drawing on thousands of years of medical texts and recent cutting-edge studies in pulmonology, psychology, biochemistry, and human physiology, Breath turns the conventional wisdom of what we thought we knew about our most basic biological function on its head. You will never breathe the same again.

    And like it or not, it’s one of the most important things you do on a daily basis. Successful conversationshelp you advance professionally and make, maintain, and deepen relationships. Moreover, research shows that talking, when done on a substantive level, is correlated with a feeling of happiness and general well-being.Being a great conversationalist requires practice and effort. The good news is it’s a skill set anyone can acquire and refine. In just six lectures, How Conversation Works: 6 Lessons for Better Communication will teach you key strategies that can dramatically improve your ability to converse with anyone, from strangers to supervisors. Delivered by award-winning English professor Anne Curzan of the University of Michigan, this highly practical course focuses on the fundamental principles you need to know to become more conversationally aware and savvy at home, in the workplace, and beyond.You’ll be amazed by how much you can learn by stepping back from conversations and examining how they operate. You’ll notice things you never picked up on before—like what kind of speaker you are, the strategies you typically rely on (often without realizing it), and the subtleties of the strategies others may use when speaking with you. You’ll find yourself putting these lessons into practice to create more effective dialogues from the very first lecture.Choose Your Words WiselyAn expression like “shooting the breeze” makes conversation sound easy and free-flowing, but even low-stakes conversations have an underlying systematic structure that propels them along. This course examines that framework while showing you how the effective selection of words can help you forge connections and accomplish your objectives.Professor Curzan walks you through techniques for negotiating a variety of difficult situations, from proffering successful apologies to engaging in “face-threatening acts”—those uncomfortable moments that have the potential to do damage if your words aren’t chosen carefully.You’ll learn graceful ways of pointing out a mistake; asking someone to do something he or she doesn’t want to do; preparing a person for “no”; asking for a big favor; and providing information the recipient doesn’t want to hear.Conversations can only deepen connections when you pull your weight. In How Conversation Works, you’ll learn this involves knowing how to skillfully open and close an exchange, take turns speaking or “negotiate the conversational floor,” and send people subtle signals.Perhaps most important is sharing the burden to make discussions feel more mutual and enjoyable. These lectures arm you with numerous conversation-facilitating devices such as asking your fair share of questions and follow-up questions, which requires active listening; providing informative (but not overly informative!) answers to other people’s questions; introducing new topics for discussion and picking up on the topics of others; and telling good stories and helping good stories along.Talk Your Way to SuccessWhether you want to build rapport with colleagues, promote your accomplishments in an interview, give a winning presentation, ingratiate yourself with your boss, or even create a connection on a first date, knowing what to say and how to say it allows for more productive, smoother interactions. How Conversation Works helps you get ahead by outlining simple techniques for accomplishing all of this and more.Short vignettes featuring professional actors demonstrate what to do—and what not to do—in a variety of everyday scenarios such as striking up a conversation at a party. In video formats, green-screen technology places the professor in a range of environments as she provides concrete advice for taking an uncomfortable conversation in a new direction, making polite requests, mastering the “humble brag,” limiting your “talk time,” and monitoring your use of distracting discourse markers such as “um” and “you know.”In addition to sharing these out-the-door tips and techniques, Professor Curzan dispels common myths about conversation and presents enlightening research on how the conversational styles of men and women share much in common, despite differences in socialization; how you may be perceived for using direct speech or sentence fillers; how language-style matching quickly creates a sense of compatibility; how parents serve as conversational role models; and how e-communication has surprisingly systematic conventions.A Guide for the Real WorldAs a professor of English and linguistics and member of the American Dialect Society, Professor Curzan offers a refreshing yet scholarly take on the subject of conversation. Using a developmental and skills-based approach that gets right to the heart of the matter, her course provides tangible, actionable methods that can be worked into your conversational repertoire immediately. At first, the newfound awareness you’ll acquire from How Conversation Works may cause you to become self-conscious when you speak, but the act of “conversational noticing” will soon become second nature. Before long, you’ll realize you have the tools to make yourself clearly understood, put others at ease, rescue a conversation that’s gone wrong—and keep conversations from going off course in the first place.

    Our eyes play tricks on us; our stories change in the retelling; and most of us are fairly sure we’re way above average. In Why We Make Mistakes, journalist Joseph T. Hallinan sets out to explore the science of human error—how we think, see, remember, and forget, and how this sets us up for wholly irresistible mistakes.In his quest to understand our imperfections, Hallinan delves into psychology, neuroscience, and economics, with forays into aviation, consumer behavior, geography, football, stock picking, and more. He discovers that some of the same qualities that make us efficient also make us error prone. Why We Make Mistakes is enlivened by real-life stories--of weathermen whose predictions are uncannily accurate and a witness who sent an innocent man to jail--and offers valuable advice, such as how to remember where you’ve hidden something important. He explains why multitasking is a bad idea, why men make errors women don’t. This book will open your eyes to the reasons behind your mistakes and have you vowing to do better the next time.

    And your life is literally shaped by it.Many of the decisions you make are decided by talking. You may be in a restaurant asking a waiter for an unusual substitution, urging a service manager to get your car finished sooner rather than later, or trying to sway your significant other toward a particular film or show. Or you might be trying to build more cooperative relationships at the office.No matter why you engage in face-to-face talk, though, there's no way to insulate yourself from the dangers of miscommunication. Your ability to use the art of talk to effectively convey who you are and to build solid relationships not only influences the success of your friendships, romantic life, and everyday encounters, but also how you experience your workplace. Studies show that using conversational skills properly in that arena makes you more productive, happier, and less stressed.But the truth is that most of us don't understand nearly as well as we could how conversation really works, whether in the office or out of it, with both parties often having entirely different perceptions of what the words and gestures passing back and forth are meant to convey. Even more important, most of us aren't as successful as we could be in making those conversations work better for us. Even when we're more skilled at it than the average person, we often give up the opportunity to be even better, leaving a lot of potential success and happiness on the table.Effective Communication Skills is your chance to learn more about how you communicate verbally, the common problems you can encounter in doing so, and how you can improve your own effectiveness—especially by overcoming the psychological and biological hard-wiring that too often gets in the way.In 24 mind-opening lectures, Professor Dalton Kehoe of Canada's York University brings more than four decades of experience as an award-winning teacher, author, and successful business consultant to this exploration of what's really going in any conversation you take part in.

    Increases in droughts, heat waves, tornadoes and poison ivy—to name a few—are all blamed on our “sins of emissions” from burning fossil fuels and increasing carbon dioxide in the atmosphere. Yet, you don’t quite buy into this human-caused climate apocalypse. You aren’t sure about the details because you don’t have all the facts and likely aren’t a scientist. Inconvenient Facts was specifically created for you. Writing in plain English and providing easily understood charts and figures, Gregory Wrightstone presents the science to assess the basis of the threatened Thermageddon.The book’s 60 “inconvenient facts” come from government sources, peer-reviewed literature or scholarly works, set forth in a way that is lucid and entertaining. The information likely will challenge your current understanding of many apocalyptic predictions about our ever dynamic climate.You will learn that the planet is improving, not in spite of increasing CO2 and rising temperature, but because of it. The very framework of the climate-catastrophe argument will be confronted with scientific fact.Arm yourself with the truth.

    893 Western civilization is closely associated with reason and science, and with exceptional accomplishment in art, architecture, music, and literature. Yet it has also been characterized by widespread belief in the supernatural and the irrationalwith mystics who have visions of the divine, and with entire movements of people who wait in fervent anticipation of the apocalypse. In addition, Western culture has been the setting for repeated acts of barbarism: persecutions of certain groups such as Jews, or accused heretics and witches. Why has this been the case? This two-part series invites you to consider what might be called the "underbelly" of Western society, a complex mixture of deeply embedded beliefs and unsettling social forces that has given rise to our greatest saints and our most shameful acts. The "terror of history," according to Professor Teofilo F. Ruiz, is a deeply held beliefdating from the ancient Greeks to Nietzsche and beyondthat the world is essentially about disorder and emptiness, and that human beings live constantly on the edge of doom. We see history as terrifying, so we try to escape it. One strategy is to withdraw through transcendental experiences. Another, unfortunately, is to shift our fears onto scapegoats such as lepers, nonconformists, and other outsiders whom we choose to blame for "the catastrophe of our existence," as Professor Ruiz puts it.
