Your cell phone is mainly made of plastics and metals. It’s easy to appreciate the process by which those elements add up to something so useful. But there’s another story we don’t hear about -- how did we get our raw ingredients in the first place, from the chaotic tangle of materials that is nature? Iddo Magen uncovers the answer in a group of clever hacks known as separation techniques.

Kant's Critique of Pure Reason - Dan Robinson at Oxford University

Professor Dan Robinson gives a series of lectures on Immanuel Kant's Critique of Pure Reason. It remains a matter of controversy as to just what the central project of the Critique is, but surely one objective is to establish the character and range of objective knowledge in light of the limits of sense and reason. The lectures in this series are intended to clarify the major claims advanced by Kant in this connection, and to test the arguments he adduces in their support. This series of talks was given at Oxford.

Professor Dan Robinson of Oxford University gives a series of eight lectures on Thomas Reid's critique of the work of David Hume. Under "David Hume", the Stanford Encyclopedia of Philosophy begins with, "The most important philosopher ever to write in English". His most formidable contemporary critic was the fellow Scot, Thomas Reid, the major architect of so-called Scottish Common Sense Philosophy. The most significant features of Hume's work, as understood by Reid, are the representative theory of perception, the nature of causation and causal concepts, the nature of personal identity, and the foundations of morality. Each of these topics is presented in a pair of lectures, the first summarizing Hume's position and the second Reid's critique of that position.

Romare Bearden: A Black Odyssey (Columbia University)

ROMARE BEARDEN: A BLACK ODYSSEY | 2015

 In 1977, Romare Bearden (1911-1988), one of the most powerful and original artists of the 20th century, created a cycle of 20 collages and watercolors (miniature variations of his collages) based on Homer’s epic poem The Odyssey. Rich in symbolism and allegorical content, Bearden’s “Odysseus Series” created an artistic bridge between classical mythology and African-American culture. The works conveyed a sense of timelessness and the universality of the human condition, but their brilliance was displayed for only two months in New York City before being scattered to private collections and public art museums.

 The Miriam and Ira D. Wallach Gallery showing of Romare Bearden: A Black Odyssey was the first time these works will be seen again in New York City since they were created. Romare Bearden: A Black Odyssey underscores the fact that this tale of the dislocated but heroic traveler's search for a way home is Bearden's own most pervasive and important artistic theme. The addition of a collage from Bearden's 1968 series, "House in Cotton Field," invites the viewer to consider the artist's Homeric collages not as rarefied explorations of Western antiquity, but as evocations of familiar seekers of a welcoming place to stay.

 The exhibition features some 50 works, including collages, watercolors, and line drawings as well as additional compositions relating to Bearden’s interest in classical themes, such as examples of his mid-1940s drawings based on Homer's other epic, The Iliad. The additional works greatly increase the resonance and power of the original 20 collages and examine Bearden’s motivations in creating these works within the context of the “Odysseus Series” and his overall body of work.

 For the Wallach Gallery presentation, singular materials were added from Columbia’s Rare Book and Manuscript Library, including a 1935 special edition of James Joyce's Ulysses produced by The Limited Editions Club. The book contains reproductions of 20 preliminary drawings and six etchings by Henri Matisse, who based his illustrations on six episodes in Homer's Odyssey. Several of Matisse’s original etched plates will also be displayed, allowing visitors to consider a related but very different artistic visualization of the Odyssey.

 The Limited Editions Club was founded in 1929 by George Macy, who endeavored to match classic texts with fine artists, creating distinctive volumes that became renowned in rare book circles. Visitors to the Wallach will be able to see the continuity of this tradition with the addition of the lush 1983 volume, Poems of the Caribbean by Derek Walcott, selected and illustrated by Bearden. Almost 50 years later, the Bearden-Walcott Limited Editions Club publication offers another yet another example of visual artists engaging the written word.

 Born in Charlotte, N.C., Bearden moved with his family to Harlem as a young child, part of the migration of African Americans from the South to greater opportunity in the North. Throughout his career, Bearden created images of the lives of travelers on their way to and from home, a theme no more powerfully explored than in his “Odysseus Series.” Bearden had examined classical themes before, but the “Odysseus Series” expanded his exploration of literary narratives and artistic genres by presenting his own personal reinterpretation of the subject.

 Romare Bearden: A Black Odyssey is curated by English and jazz scholar Robert G. O’Meally, the Zora Neale Hurston Professor of English and Comparative Literature and founder and former director of the Center for Jazz Studies at Columbia. The exhibition is complemented by a fully illustrated companion book of the same name (DC Moore Gallery, 2008), written by O’Meally. The book includes full-color images of Bearden’s work and an essay by O’Meally. The Smithsonian Institute has also developed a comprehensive website for the exhibition project.

 “In creating a black Odyssey series, Bearden not only staked a claim to the tales of ancient Greece as having modern relevance, he also made the claim of global cultural collage—that as humans, we are all collages of our unique experiences,” said O’Meally. “Indeed, Bearden does not merely illustrate Homer - he is Homer’s true collaborator, and he invites us as viewers to inherit Homer’s tale and interpret it as our own.”

This Ahlfors-Bers Conference is the sixth in a series of triennial colloquia devoted to the mathematical legacy of Lars Ahlfors and Lipman Bers. The core heritage is in geometric function theory, quasiconformal mapping, Teichmüller theory and Kleinian groups, hyperbolic manifolds, and partial differential equations including Schramm/Stochastic-Loewner-Evolution/Equations. Today we see the influence of Ahlfors and Bers on algebraic geometry, mathematical physics, dynamics, probability, geometric group theory, number theory and topology.

從一百多年前馬可尼發出那通越洋無線電報開始,無線通訊便正式進入我們的生活;時至今­日,手機主導了多數人的生活型態。手機及各種穿戴式裝置之所以能相互通訊,均是透過電­磁波傳遞訊號;而電磁波看不見、摸不著,許多人因為不瞭解而聞「波」色變;其實,電磁­波跟聲波、水波一樣,是一種傳遞能量的方式,並不可怕。

在本講中,陳教授將依循電磁學的發展脈絡介紹電磁波的基本現象,並談談發射與接收電磁­波的利器¾天線及其工作原理,最後,根據電磁波與天線的特性,討論無線通訊系統的可能­架構與未來發展。

Carmine Gallo: "The Storytellers Secret" | Talks at Google


source: Talks at Google     2016年4月1日
Communications expert Carmine Gallo talks about his new book, "The Story Tellers Secret" to teach us why some ideas stick and others don't.
While the roots of storytelling are ancient, Gallo shares the latest science that proves its impact, which only became evident in just the past decade. Neuroscientists helped us understand why the brain is hardwired for story, and why some stories trigger a rush of neurochemicals like cortisol, oxytocin, and dopamine. These elements cause people to pay attention, form empathy and feel good, helping explain why nothing moves hearts and minds like a great story.
The science of storytelling that Gallo uncovers here helps explain why:
Some TED talks go viral – and others are forgettable;
Some leaders start movements – and others miss the mark;
Some companies have high employee engagement – and others see high turnover;
Some non-profits raise millions of dollars – and other struggle;
Some job candidates stand out and others can’t persuade recruiters;
Some entrepreneurs change the world – and others don’t;
Why do we need to hone our skills at storytelling? Because the ability to package ideas into a compelling story is one of the most proven skills that makes leaders successful. The power of narrative allows messages to make a difference (and not fall on deaf ears) – is a skill as important for visionary leaders and political candidates, as it is for business leaders, professionals, parents, teachers, and job seekers.
