England's Greatest Garden Designer – Capability Brown
source: University of Oxford 2016年8月19日
It is 300 years since the birth of Lancelot ‘Capability’ Brown, who designed the gardens of some of England’s most beloved country houses. Dr Oliver Cox, Heritage Engagement Fellow at the University, tells us about ‘the man behind England’s green and pleasant land’.

Space, Time, and Consciousness with Vernon Neppe
source: New Thinking Allowed 2016年5月16日
Vernon Neppe, MD, PhD, FRSSAf, is a neuropsychiatrist and head of the Pacific Neuropsychiatric Institute in Seattle. He is author, with physicist Edward Close, of Reality Begins with Consciousness: A Paradigm Shift that Works. He is also author of Déjà Vu Revisited, Déjà Vu: A Second Look, Déjà Vu: Glossary and Library, Cry the Beloved Mind: A Voyage of Hope, and Innovative Psychopharmacotherapy. His professional publications number over 700. Dr Neppe has amplified many of his concepts in two of the websites linked with his work. On www.Brainvoyage.com, his books are amplified. www.VernonNeppe.org is his gateway and includes more information on the Neppe-Close model of the Triadic Distinction Vortical Paradigm.
Here, Dr. Neppe describes his work with Dr. Close in developing a new paradigm that could account for consciousness and psi phenomena within a mathematical and physical framework. His approach is one in which space, time, and consciousness are tethered together. He calls this unified monism. His model also entails nine mathematical dimensions.
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 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.

Living the Best Life Possible: Doctor and Patient Conversations About Serious Illness and Mortality
source: Harvard University 2015年3月18日
Many Americans may confront illnesses so serious that they are life threatening. These diagnoses may come with treatment attempts and hospital stays. What they may not include are honest and open conversations about the final stages of life. How might the patient want to live during these stages? What choices are most likely to bring a sense of peace and empowerment? How might family members be included in these discussions? A growing palliative care movement is encompassing these questions, bringing together doctors, patients and their families in a new and compassionate way. This Forum event examined this movement, taking a look at the Serious Illness Care Program system developed at Ariadne Labs, as well as the upcoming launch of a national collaborative to test the use of this program in multiple healthcare systems in the U.S. This event also reviewed issues within healthcare systems, including utilization of end-of-life services and the debate around the role of payment for value.
Presented March 17, 2015 in Collaboration with PRI’S The World and WGBH.

Hilary Putnam Interview on Philosophy of Science (Subtitles Available)
source: Philosophical Overdose 2015年11月9日
Bryan Magee and Hilary Putnam discuss the philosophy of science and the philosophy of mathematics. An introductory overview is given of some of the conceptual issues which arise regarding the nature of knowledge and science including demarcation, methodology, foundations, as well as the notion of truth and objectivity, the fact-value dichotomy, inductive logic, reductionism, materialism, etc.
Hilary Putnam was an American philosopher, mathematician, and computer scientist who was a central figure in analytic philosophy. He made important contributions in logic, philosophy of mind, epistemology, philosophy of language, philosophy of science and mathematics.
I recommend his book "Reason, Truth, and History" which can be found online here:https://ia902606.us.archive.org/23/it...
This interview is from a 1978 BBC program. Transcript/subtitles are available.

Mark Z. Danielewski: "The Familiar" | Talks At Google
source: Talks at Google 2016年8月11日
Mark Z. Danielewski, the internationally bestselling author of "House of Leaves" and the National Book Award nominated "Only Revolutions," comes to Google to discuss his planned 27-volume epic, "The Familiar," of which Volume 3 was released in June 2016.
The novel ranges from Mexico to Southeast Asia, from Venice, Italy, to Venice, California, with nine lives hanging in the balance, each called upon to make a terrifying choice. At the very heart, though, is a twelve-year-old girl named Xanther who one rainy day in May sets out with her father to get a dog, only to end up trying to save a cat as fragile as it is dangerous. The series continues the spectacular visuals and vibrant wordplay that are Danielewski's trademark, making "The Familiar" a beautiful and singular reading experience.
History Lesson: Religion's Portrayal of 'Hell' is Totally Misunderstood ...
source: Big Think 2016年8月21日
A lot of us are banking on heaven for ourselves and hell for certain others, but spiritual teacher Rob Bell urges us to think about those concepts as states of consciousness, and rethink the nature of the afterlife. Bell's latest book is "How to Be Here: A Guide to Creating a Life Worth Living" (http://goo.gl/DW7wMQ).

Transcript - I begin with heaven and hell as states of consciousness and reflections of the kind of world that we’re creating right now. So when people say well where is hell they’re essentially saying it is a dimension or a human experience that is absent of anything good, peaceful, generous, redemptive. So the idea that has animated a lot of religion for a lot of people that there is some divine being somewhere who if you don’t say or do or pray or think the right or believe the right thing is going to send you to hell. Life is difficult enough without believing that the deepest, strongest forces of the universe are against you and are going to torture you forever. One of the things I found most interesting is that Jesus used the word hell but when he used the word hell he was referring to an actual place in the city of Jerusalem in the first century. The word he used was the word Gehenna. And Gehenna means a valley of Hinnom.
And the valley of Hinnom was the south valley on the south wall of the city of Jerusalem and it’s where people tossed their trash. So he’s pretty much the only person who used it and when he used this word he was referring to a real place where this trash was burning. So essentially he was saying you as a human being, you have this power to make choices about whether you will move towards others in grace and compassion and kindness or you will move towards people in violence and degradation. And when you do that, when you mistreat others, when you are indifferent to their suffering you are essentially creating like a Hinnom on earth. And so you’re creating a hell on earth. So I begin with these as very powerful words and pictures of what we as human beings can create right now. And when you talk about that apparently for a lot of religious people being right isn’t enough. It’s being right and other people being wrong. It’s being in and other people being out. It’s being part of the chosen and other people not being part of the chosen. For many people going back to why spirituality has been so sort of corrupted for so many people, for many people their fundamental understanding of the spiritual life was figuring out who’s got it, who doesn’t, who’s in, who’s out. And I begin with a much more inclusive love for everybody. But then we can right now choose to live particular ways in this world. That’s a really long answer about hell. It was all over the place.

Boosting Vitamin D: Not Enough or Too Much? - Harvard School of Public Health
source: Harvard University 2012年1月26日
A long-awaited report from the Institute of Medicine (IOM), "Dietary Reference Intakes for Calcium and Vitamin D," calls for increasing daily vitamin D intake. Yet some experts say these new recommendations are still too low in vitamin D. Why do these nutrition specialists disagree? This Forum webcast examined the question, "Boosting Vitamin D: Not enough or too much?" Presented in collaboration with Reuters. Part of the Andelot Series on Current Science Controversies.
