Description:
Despite the majority of public school students becoming increasingly nonwhite (50 percent), the majority of public school teachers -- 80 percent -- are white. With decades of initiatives to recruit minority teachers into the profession have struggled to keep them in schools. According to Ed Magazine, an estimated 47,600 minorities became teachers in 2003–04 but by the end of the school year, more than 56,000 minority teachers overall had left the profession. Join us as we discuss the significant role of minority teachers in the school system, student lives, and education policy, as well as the challenges in recruiting and retaining these teachers.

The Life & Work of Arthur Schopenhauer

source: Philosophical Overdose     2016年11月8日
BBC's In Our Time: Melvyn Bragg and guests AC Grayling, Beatrice Han-Pile and Christopher Janaway discuss the dark, pessimistic philosophy of Arthur Schopenhauer. As a radical young thinker in Germany in the early 19th century, Schopenhauer railed against the dominant ideas of the day. He dismissed the pre-eminent German philosopher Hegel as a pompous charlatan, and turned instead to the Enlightenment thinking of Immanuel Kant for inspiration. Schopenhauer's central idea was that everything in the world was driven by the Will - broadly, the ceaseless desire to live. But this, he argued, left us swinging pointlessly between suffering and boredom. The only escape from the tyranny of the Will was to be found in art, and particularly in music. Schopenhauer was influenced by Eastern philosophy, and in turn his own work had an impact well beyond the philosophical tradition in the West, helping to shape the work of artists and writers from Richard Wagner to Marcel Proust, and Albert Camus to Sigmund Freud. AC Grayling is Professor of Philosophy at Birkbeck College, University of London; Beatrice Han-Pile is Professor of Philosophy at the University of Essex; Christopher Janaway is Professor of Philosophy at the University of Southampton.

Iranian Renaissance with Jason Reza Jorjani

source: New Thinking Allowed      2016年11月10日
Jason Reza Jorjani is a philosopher and faculty member at the New Jersey Institute of Technology. He is author of Prometheus and Atlas.
Here he discusses the influence of pre-Islamic, Zoroastrian culture on the society within Iran following the Arab conquest. He notes that Islamic Sufism borrowed heavily from an esoteric strain of Zoroastrianism known as Mazdakism. He also maintains that the Arabic preservation of ancient Greek texts was largely done through the auspices of Persian scholars. These texts eventually were instrumental in the vast flowering of European culture known as the Renaissance. Today, within Iran, there exists a movement known as the Iranian Renaissance. Millions of young Iranians are wearing Zoroastrian symbols and are endeavoring to learn about the ancient, Persian past. Much of the inspiration for this movement comes from a text known as the Shahnameh or Persian Book of Kings.

New Thinking Allowed host, Jeffrey Mishlove, PhD, is author of The Roots of Consciousness, Psi Development Systems, and The PK Man. Between 1986 and 2002 he hosted and co-produced the original Thinking Allowed public television series.

What is in Common Between Quantum Computer and Solar System? (by Boris Altshuler)

source: GoogleTechTalks      2016年11月10日
A Google TechTalk, 10/21/16, presented by Boris Altshuler.
ABSTRACT: Quantum Computers (QC) consist of a large number of interacting quantum bits. Solutions of computational problems are encoded in bit-strings which result from problem-specific manipulations. In contrast with Classical Computers, the state of a QC is characterized by a quantum superposition of the bit-strings (a wave function) rather than by a particular bit-string representing a computational basis. Instead of usual focus on quantum algorithms, here we will discuss QC using concepts from many-body physics as quantum dynamical systems. Recent progress in understanding the dynamics of quantum systems with large number of degrees of freedom is based on the concept of Many-Body Localization: the eigenstates can be localized in the Hilbert space in a way similar to the conventional real space Anderson Localization of a single quantum particle by a quenched disorder. Depending on the temperature (total energy) or other tunable parameters the system can find itself either in the localized or in the many-body extended phase. In the former case, the system of interacting quantum particles/spins cannot be described in terms of conventional Statistical Mechanics: the notion of the thermal equilibrium loses its meaning. Moreover the violation of the conventional thermodynamics does not disappear with the Anderson transition to an extended state. In a finite range of the tunable parameters we expect the non-ergodic extended phase: the many-body wave-functions being extended are multifractal in the Hilbert space making thermal equilibrium unreachable in any reasonable time scale. It means the system by itself keeps some memory of its original quantum state. This property can be extremely useful for quantum computation, which cannot be implemented without connection between the remote parts of the Hilbert space, i.e. states localized in the computational basis are useless. The ergodic states should also be avoided: in the Hilbert space of high dimension they easily lose the quantum information. We will discuss evidences for the existence of delocalized non-ergodic systems and speculate about their properties by comparing them with non-integrable classical dynamical systems such as Solar Systems.

Christina Hendricks: Sigmund Freud, Civilization and its Discontents (01/27/2015)

source: Arts One Open     2015年1月27日
Christina Hendricks begins this lecture by giving some background in a few Freudian ideas and arguments that may help in making sense of the text, and then talks about connections between this text, Rousseau's Discourse on the Origin of Inequality, Plato's Republic, and Nietzsche's Twilight of the Idols, while giving her reading of some of the main points of Freud's arguments. She ends with a quick question about the choice to start the book with a discussion of the "oceanic feeling" only to seemingly drop it, and then argues that we can see it reappear as a theme, in a way, in the end of the book.

Analyzing Language (2): Bertrand Russell's Theory of Descriptions

source: Philosophical Overdose      2013年6月20日
Stephen Neale discusses Bertrand Russell's famous theory of descriptions and some of the philosophical issues surrounding it involving the nature of language and thought. The theory was introduced in Russell's article "On Denoting" and has made significant contributions to the philosophy of language, as well as logic, epistemology, and metaphysics. Among other things, it made sense out of how we are able to speak and think about non-existent objects. The epistemology which motivated the theory was based on Russell's conception of sense data and his distinction between knowledge by acquaintance and knowledge by description.

Imagine, for a second, a duck teaching a French class. A ping-pong match in orbit around a black hole. A dolphin balancing a pineapple. You probably haven’t actually seen any of these things. But you could imagine them instantly. How does your brain produce an image of something you’ve never seen? Andrey Vyshedskiy details the neuroscience of imagination.

Conference: “Redefining Urban Design: Barcelona as Case Study" Part 2

source: Harvard GSD      2016年11月3日
The theme of this conference is the extent to which new, emerging issues are changing the principles of urban design and its practice at the scale of the city and territory. Topics to be explored include the future of the traditional city and modern districts constructed thus far; the new urban forms that have come into being along with the innovation economy; the potential influence of the hypermobility that global centers appear to promote; and forms of economic and urban development that may have been neglected amid the models of the widespread growth of housing and infrastructure that were so influential in the twentieth century.By considering several different issues in Barcelona, including case studies in the concurrent exhibition Barcelona: Metropolis of Cities, the conference aims not only to examine the urban transformation of that city since the 1980s but also to reflect on how its recent history may shed light on the urban development of other cities across the globe. The conference will thus explore a new dimension of the urban design project as such, in which multidisciplinary reflections on the similarities and differences between a specific case study and innovative trends in other cities may disclose new fields for reflection, orientation, and coordination of the various disciplines and scales involved in the design and management of the city. Organized by Joan Busquets, Martin Bucksbaum Professor in Practice of Urban Planning and Design.

Janet Wiles: "Talking with Robots" | Talks at Google

source: Talks at Google      2016年11月9日
Robots are beginning to deliver pizza and parcels, drive cars and help the kids with their homework. How will they communicate with us? They can download a dictionary and start talking, but a dictionary doesn’t understand its own words and nor would the robots. Language is not that simple. So, could a robot ever say-what-it-means and mean-what-it-says? This talk is about how robots, called Lingodroids, understand language by inventing their own words to describe their own experiences. Such robots roam the world, asking each other questions like “Where are we” and “What time is it?” Through these conversations, they invent words for places and times, linking the meanings to their own experiences. Linking a place in the world to its name is called “grounding” and it is the first step in having robots truly understand what they say. Human languages can refer not only to previous experiences, but also to possible experiences, and even impossible ones. The talk will describe how the Lingodroids invent robot languages, and generalise their words to refer to places they have never been, and even places they can reach only in their imagination. The talk will finish with a glimpse into how conversations with people can help robots learn the meanings of words in human languages.
