    Owing to the work of an astonishing range of visionary thinkers, this fascinating period was the era in which the foundations of the modern Western world were laid. In the medieval era's great minds we find the roots of many aspects of today's world - from the religious/philosophical thought of Augustine, Ambrose of Milan, and Thomas Aquinas to the scientific innovations of Avicenna and Alhacen, the enlightened statesmanship of Charlemagne and Lorenzo de Medici, and the literary creations of Dante and Chaucer.In these 24 lectures, Professor Armstrong leads you on an enthralling journey into the lives of the seminal thinkers of the Middle Ages. In this gallery of extraordinary minds, you'll encounter the leading lights of a world-shaping era, including figures such as Maimonides, Hildegard of Bingen, Bernard of Clairvaux, Peter Abelard, and Francesco Petrarch. Professor Armstrong goes to great lengths to bring these historic figures to life, revealing both the great intellectual contributions and the personal strivings, challenges, and triumphs of some of history's most remarkable human beings. These compelling lectures take you deeply into the heart of one of civilization's most dynamic and impactful eras.Listening Length: 11 hours and 59 minutes

    In this course, The Great Courses partners with the Smithsonian - one of the world's most storied and exceptional educational institutions - to examine the extraordinary events of this period and uncover the far-reaching impact of this incredible revolution. Over the course of 36 thought-provoking lectures, longtime Great Courses favorite Professor Allitt introduces you to the inventors, businessmen, and workers responsible for transforming virtually every aspect of our lives and fueling one of the greatest periods of innovation in human history. The technological achievements of this era are nothing short of astonishing. Thanks to inventions such as the steam engine and processes such as large-scale iron smelting, industrial entrepreneurs were able to mechanize labor, which allowed for a host of new efficiencies such as division of labor, mass production, and global distribution. You'll discover the science behind some of the most astounding inventions in modern history, including the spinning jenny, the incandescent light bulb, and the computer processor. You'll learn how these inventions came about and consider what effects these technologies had on every aspect of human life. Get an inside look at the history of industrial innovation and explore the lives of engineers, inventors, architects, and designers responsible for changing the world - as well as ordinary workers who lost their livelihoods to new technologies and suffered from unsafe working conditions. The story of the Industrial Revolution is complex, and these lectures will leave you with a new appreciation for the amazing human achievements all around us.

    Extremely elusive and difficult to pin down, neutrinos are not unlike the brilliant and eccentric scientists who doggedly pursue them.In Neutrino Hunters, the renowned astrophysicist and award-winning writer Ray Jayawardhana takes us on a thrilling journey into the shadowy world of neutrinos and the colorful lives of those who seek them. Demystifying particle science along the way, Jayawardhana tells a detective story with cosmic implications—interweaving tales of the sharp-witted theorist Wolfgang Pauli; the troubled genius Ettore Majorana; the harbinger of the atomic age Enrico Fermi; the notorious Cold War defector Bruno Pontecorvo; and the dynamic dream team of Marie and Pierre Curie. Then there are the scientists of today who have caught the neutrino bug, and whose experimental investigations stretch from a working nickel mine in Ontario to a long tunnel through a mountain in central Italy, from a nuclear waste site in New Mexico to a bay on the South China Sea, and from Olympic-size pools deep underground to a gigantic cube of Antarctic ice—called, naturally, IceCube.As Jayawardhana recounts a captivating saga of scientific discovery and celebrates a glorious human quest, he reveals why the next decade of neutrino hunting will redefine how we think about physics, cosmology, and our lives on Earth.

    As a result, whether we realize it or not, the drive to obtain food has been a major catalyst across all of history, from prehistoric times to the present. Epicure Jean-Anthelme Brillat-Savarin said it best: "Gastronomy governs the whole life of man." In fact, civilization itself began in the quest for food. Humanity's transition to agriculture was not only the greatest social revolution in history, but it directly produced the structures and institutions we call "civilization." In 36 fascinating lectures, award-winning Professor Albala puts this extraordinary subject on the table, taking you on an enthralling journey into the human relationship to food. With this innovative course, you'll travel the world discovering fascinating food lore and culture of all regions and eras - as an eye-opening lesson in history as well as a unique window on what we eat today.

    We wouldn’t have unraveled DNA or discovered Neptune or figured out how to put 5,000 songs in your pocket. Though many of us were scared away from this essential, engrossing subject in high school and college, Steven Strogatz’s brilliantly creative, down‑to‑earth history shows that calculus is not about complexity; it’s about simplicity. It harnesses an unreal number—infinity—to tackle real‑world problems, breaking them down into easier ones and then reassembling the answers into solutions that feel miraculous. Infinite Powers recounts how calculus tantalized and thrilled its inventors, starting with its first glimmers in ancient Greece and bringing us right up to the discovery of gravitational waves (a phenomenon predicted by calculus). Strogatz reveals how this form of math rose to the challenges of each age: how to determine the area of a circle with only sand and a stick; how to explain why Mars goes “backwards” sometimes; how to make electricity with magnets; how to ensure your rocket doesn’t miss the moon; how to turn the tide in the fight against AIDS. As Strogatz proves, calculus is truly the language of the universe. By unveiling the principles of that language, Infinite Powers makes us marvel at the world anew.

    It far surpasses any previous explanation of Relativity for laypersons.

    The fascinating tales in The Disappearing Spoon follow carbon, neon, silicon, gold and every single element on the table as they play out their parts in human history, finance, mythology, conflict, the arts, medicine and the lives of the (frequently) mad scientists who discovered them.Why did a little lithium (Li, 3) help cure poet Robert Lowell of his madness? And how did gallium (Ga, 31) become the go-to element for laboratory pranksters? The Disappearing Spoon has the answers, fusing science with the classic lore of invention, investigation, discovery and alchemy, from the big bang through to the end of time.

    How does Jane Goodall’s relationship with her dog Rusty inform her thinking about our relationship to other species? Which time and place would Jared Diamond most prefer to live in, in light of his work on the role of chance in history? What does driving a sports car have to do with Steven Weinberg’s quest for the “theory of everything”? Physicist and journalist Stefan Klein’s intimate conversations with nineteen of the world’s best-known scientists (including three Nobel Laureates) let us listen in as they talk about their paradigm-changing work—and how it is deeply rooted in their daily lives. • Cosmologist Martin Rees on the beginning and end of the world • Evolutionary biologist Richard Dawkins on egoism and selflessness • Neuroscientist V. S. Ramachandran on consciousness • Molecular biologist Elizabeth Blackburn on aging • Philosopher Peter Singer on morality • Physician and social scientist Nicholas Christakis on human relationships • Biochemist Craig Venter on the human genome • Chemist and poet Roald Hoffmann on beauty
