Exhibition Opening: “Towards a Critical Pragmatism: Contemporary Architecture in China"

source: Harvard GSD 2016年9月15日
This discussion marks the opening of the exhibition Towards a Critical Pragmatism: Contemporary Architecture in China, in the main gallery of Gund Hall. With the aim of encouraging further conversation about the present and future state of China’s architecture culture, the exhibition highlights several buildings in five thematic categories—cultural, regeneration, digital, rural, and residential—and showcases the architects’ commitment to conceptual criticality and quality of production. Curator Xiangning Li, visiting professor of architecture (spring 2016), will discuss the exhibition and the current situation with Michael Hays, Eliot Noyes Professor of Architectural Theory; Jing Liu, exhibition designer and principal of SO-IL; Antoine Picon, G. Ware Travelstead Professor of the History of Architecture and Technology; and Pei Zhu (Studio Pei-Zhu).

John Asher Johnson, "Hot on the Trail of Warm Planets Around Cool Stars"

source: Harvard University 2016年8月31日
Just three years ago the prospect of finding temperate, rocky worlds around other stars was still the subject of science fiction: none had been found and reasonable estimates put us years or decades away from such a momentous discovery. All of that has changed very recently on the heels of the extraordinarily successful NASA Kepler mission. By searching for the tiny diminutions of starlight indicative of an eclipsing planet, Kepler has produced thousands of new planet candidates orbiting distant stars. Careful statistical analyses have shown that the majority of these candidates are bona fide planets, and the number of planets increases sharply toward Earth-sized bodies. Even more remarkably, many of these planets are orbiting stars right “next door.” Professor Johnson describe the multi-telescope campaign to validate and characterize these tiny planetary systems, and presents some early, exciting results that point the way toward a large sample of Earth-sized planets in the habitable zones of nearby stars.

Transcript - Technology can be used against us in ways that we don’t understand. Most people in our modern society have become expert users of technology but they have no idea how things operate under the hood. This is true of all generations, particularly with millennials. People think millennials are great with tech and it’s true they’re expert users. But when it comes to understanding the science of technology, the computer and science and the electrical engineering that goes into making a particular app work most people are clueless. And the challenge of that is that there are people in our world who know how technology works. The people who create those tools out in Silicon Valley and elsewhere and then other people who take the time to educate themselves. Whether it be people who have studied it professionally or on their own but in particular even criminals and terrorists and rogue governments have worked on these tools, decompiled them, deconstructed them and the fact of the matter is most criminals understand your iPhone better than you do and can use it against you.
When people think of cybercrime or computer crime they always think of the basics. My credit card number got hacked. My identity was stolen. That type of stuff. It’s so common these days to tap into most people at one point in their life or another. But there are so many other things that criminals can do with technology that the average person wouldn’t even realize. So let’s take your mobile phone for example. There was an android exploit that came out recently called Stagefright and just by sending a text message to an individual on an android phone anybody who read those messages or clicked on the links their mobile phone could be taken over in an instant. The fascinating thing about it is is that it affected one billion android users across the world. So just one hacker could have taken over a billion android devices. And once they have access to the devices not only can they read everything that you type, get access to your entire address book, see every photograph private or not that you may have ever taken on your phone. They can get access to all your social media accounts, capture your email address and your log on credentials and password for all of your financial apps, for your bank accounts, investment accounts and the like. And they can even track you physically in the world and know where you are at any particular time. Read Full Transcript Here: http://goo.gl/PqYnyq.

Lucy Kalanithi: "When Breath Becomes Air" | Talks at Google

source: Talks at Google 2016年9月9日
Dr. Paul Kalanithi’s wrote the #1 New York Times bestselling memoir -- When Breath Becomes Air. Kalanithi was a neurosurgery resident at Stanford and a loving husband when he was suddenly diagnosed with stage IV lung cancer. He died two years later at the age of 37, eight months after his infant daughter was born. His critically acclaimed memoir, finished with the help of his widow, Dr. Lucy Kalanithi, is a profound, searingly honest, and ultimately life-affirming meditation on the challenge of facing death and the relationship between doctor and patient.
What makes life worth living in the face of death? What do you do when the future, no longer a ladder toward your goals in life, flattens out into a perpetual present? What does it mean to have a child, to nurture a new life as another fades away? These are some of the questions Kalanithi wrestles with in this profoundly moving, exquisitely observed memoir. Paul Kalanithi died in March 2015, while working on this book, yet his words live on as a guide and a gift to us all. “I began to realize that coming face to face with my own mortality, in a sense, had changed nothing and everything,” he wrote. “Seven words from Samuel Beckett began to repeat in my head: ‘I can’t go on. I’ll go on.’”
This video: In Conversation with Lucy Kalanithi and Saurabh Madaan as Lucy talks about the process of shepherding Paul’s words and ideas into the world.

A Brief History of Tomorrow | Yuval Harari | RSA Replay

source: The RSA 2016年9月8日
A Brief History of Tomorrow with bestselling author Yuval Harari. What is the next stage of human evolution? How will we protect this fragile planet and humankind itself from our own destructive powers?
We are delighted to be welcoming Yuval Noah Harari - bestselling author of Sapiens: A Brief History of Humankind – for his second much-anticipated RSA appearance. Where Sapiens was a wide-ranging exploration of humankind’s history, in his new work Homo Deus he envisions our future: a not-too-distant world in which we face a new set of challenges and possibilities.
With his trademark blend of science, history, philosophy and every discipline in between, Harari will investigate the projects, dreams and nightmares that will shape the twenty-first century – from overcoming death to creating artificial life.

Indigenous EcoPsychology, Part One: On Being Human, with Glenn Aparicio Parry

source: New Thinking Allowed 2015年11月23日
Glenn Aparicio Parry, PhD, is author of Original Thinking: A Radical Revisioning of Time, Humanity, and Nature. He is the founder and director of the Circle for Original Thinking, a think tank based in Albuquerque, New Mexico.
Here he describes his participation, for over a decade, in a series of dialogues between native American elders, academic linguists, and theoretical physicists. These meetings caused him to question very basic notions such as the nature of time. Native Americans tend to see time as circular rather than linear. He also notes that, in modern western culture, humans believe themselves to be separate from nature, whereas native Americans see themselves as part of nature. He points out that native American languages emphasize process. They have many verbs and few nouns. This was in accord with the thinking of the physicists. He discusses the role of dreams in shaping our view of reality. He challenges the notion that we can “conquer” nature.

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. He is the recipient of the only doctoral diploma in "parapsychology" ever awarded by an accredited university (University of California, Berkeley, 1980). He serves as dean of transformational psychology at the University of Philosophical Research. He teaches parapsychology for ministers in training with the Centers for Spiritual Living through the Holmes Institute. He has served as vice-president of the Association for Humanistic Psychology, and is the recipient of its Pathfinder Award for outstanding contributions to the field of human consciousness. He is also past-president of the non-profit Intuition Network, an organization dedicated to creating a world in which all people are encouraged to cultivate and apply their inner, intuitive abilities. His American Indian name, chosen at age eight, is Soaring Eagle.

Consciousness: Neuromania & Darwinitis (Raymond Tallis)

source: Philosophical Overdose 2013年1月18日
In this talk, Professor Raymond Tallis argues against what he calls Neuromania & Darwinitis regarding consciousness, free will, the self, values, and intentionality. According to Tallis, Neuromania is based on the incorrect notion that human consciousness is identical with activity in the brain, that people are their brains, and that societies are best understood as collections of brains. Although the brain is a necessary condition of every aspect of human consciousness, it is not a sufficient condition -- which is why neuroscience, and the materialist philosophy upon which it is based, fails to capture the human person. And since the brain is an evolved organism, Neuromania leads to Darwinitis, the assumption that, since Darwin demonstrated the biological origins of the organism Homo sapiens, we should look to evolutionary theory to understand what we are now; that our biological roots explain our cultures leaves.

This talk was given at the University of Hertfordshire.
