Science on Saturdays at Yale - Maureen Long - Earthquakes, Volcanoes, & Tsunamis, oh My! The Science of Natural Disasters
When the earth twitches buildings fall, volcanoes erupt, and killer waves reshape the ocean shore. Join us this Saturday to learn from Professor Maureen Long about how earth scientists use the theory of plate tectonics to understand and prepare for geologic disasters. Science on Saturdays is an award-winning lecture series that features scientists whose passion for their work inspires us all. Each event involves a lecture by a Yale professor and engaging science demonstrations by Yale college students. Science on Saturdays provides an opportunity for Yale scientists and residents of New Haven and beyond to come together over a shared sense of wonder.

Daniel Eisenstein, "Dark Energy and Cosmic Sound"
source: Harvard University 2016年8月31日
The Sound waves propagating through the plasma of the Universe only 400,000 years after the Big Bang now offer some of our most precise measures of the composition and history of the Universe. In the last decade, we have been able to detect the fossil imprint of these sound waves using maps of the distribution of galaxies from the Sloan Digital Sky Survey. Professor Eisenstein will give an overview of the cosmological role of the sound waves and our observational program then describe what the results tell us about the shape of the Universe and the evolution of dark energy.
Shamans and Their World with Stanley Krippner
source: New Thinking Allowed 2016年9月1日
Stanley Krippner, PhD, professor of psychology at Saybrook University, is a Fellow in five APA divisions, and past-president of two divisions (30 and 32). Formerly, he was director of the Maimonides Medical Center Dream Research Laboratory, in Brooklyn NY. He is co-author of Demystifying Shamans and Their World, The Voice of Rolling Thunder: A Medicine Man’s Wisdom for Walking the Red Road, Dream Telepathy, Extraordinary Dreams and How to Work with Them, The Mythic Path, and Haunted by Combat: Understanding PTSD in War Veterans, and co-editor of Debating Psychic Experience: Human Potential or Human Illusion, Healing Tales, Healing Stories, Varieties of Anomalous Experience: Examining the Scientific Evidence, Advances in Parapsychological Research and many other books. He is a Fellow of the Society for the Scientific Study of Religion, and has published cross-cultural studies on spiritual content in dreams.
Here he discusses the common features that he has observed in his studies of shamans around the world. He describes their rituals in terms of drumming, dancing, sensory deprivation, drugs, diet, and dreaming. He notes that shamans often invoke the “trickster” archetype, but that this should not be taken to imply that they are necessarily fraudulent. Shamans receive that designation from their community; and they work in the service of that community. A self-appointed healer, therefore, is not a shaman. However, all shamans are healers.
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.

A.I. Ethics: Should We Grant Them Moral and Legal Personhood? | Glenn Cohen
source: Big Think 2016年9月23日
Artificial intelligence already exhibits many human characteristics. Given our history of denying rights to certain humans, we should recognize that robots are people and have human rights.

Transcript - The question about how to think about artificial intelligence in personhood and writes artificial intelligence I think is really interesting. It's been teed up I think in two particularly good films. AI, which I really like but many people don't; it was a Stanley Kubrick film that Steven Spielberg took over late in the process. And then Ex Machina more recently, which I think most people think is quite a good film. And I actually use these when I teach courses on the subject and we ask the question are the robots in these films are they persons yes or no? One possibility is you say a necessary condition for being a person is being a human being. So many people are attracted to the argument say only humans can be persons. All persons are humans. Now maybe not be that all humans are persons, but all persons are humans. Well, there's a problem with that and this is put most forcefully by the philosopher Peter Singer, the bioethicist Peter Singer who says to reject a species, possibility of the species has rights not to be a patient for moral consideration, the kind of things that have moral consideration on the basis of the mere fact that they're not a member of your species he says is equivalent morally to rejecting giving rights or moral consideration to someone on the basis of their race. So he says speciesism equals racism. Read Full Transcript Here: https://goo.gl/QiZYh3.
Born Poor, Stay Poor: The Silent Caste System of America | C. Nicole Mason
source: Big Think 2016年8月29日
There's a lot missing from debates and policy surrounding poverty but the biggest deficit, according to Dr C. Nicole Mason, is in honesty. Impoverished people aren't poor because they're lazy, they're poor because social mobility is institutionally suppressed. Mason's latest book is "Born Bright: A Young Girl's Journey from Nothing to Something in America" (http://goo.gl/AOsgVz).

Transcript - We’re not talking honestly about what it really takes to get from poverty to the middle class. So, for example, we know that only four percent of people who are born into poverty will ever make it to the upper middle class or to, you know, have middle class success. And so what that means is that 96 percent of people are not making it out. And I think we’re being dishonest when we say everybody has a fair and equal chance of achieving the American Dream. So it wasn’t until college that I figured out that I was poor. I hadn’t – before then I had no context for what it meant to have less than other people who lived around me or across town. And I certainly didn’t know that I was outside of what was considered the middle class. And the first time that I heard about people living in poverty was in a political science class. In there we were talking about welfare policies. And one of the big policies at the time was welfare reform. And the debate was raging about what should be done and a lot of the conversation was up here and really detached from the women and families that were going to be directly impacted by the policy.
So we heard a lot of things about welfare queens, people living off the system, not wanting to work, women being lazy, having multiple children. And that really wasn’t the reality for the women who were actually impoverished. And so when we look at the kind of policies that result – the kind of policy, the welfare reform policy that we got on the other end we got a policy that said well, you can’t – if you don’t work you can’t receive benefits. And you have time limits. And if you have another child you’re penalized. Those policies and that restrictiveness was counter to the everyday lived experiences of the women who were actually receiving the benefits. So what was excluded from that policy was a clear pathway out of poverty like education. There missing – in the very beginning there was very few provisions for childcare and a lot of other things that we know family and women need to be able to chart a path out of poverty.

MS&E 476: Entrepreneurship through the Lens of Venture Capital
We often discuss how technology is reinvented and disrupted, but there is also a good amount of change occurring within the venture capital industry. Within the past several decades there have been new entrants, from incubators to angels to different models of venture capital.
The course explores changes in the venture capital industry: from the rise of Sand Hill Road and investing in the dot-com bubble, to incubators and accelerators, equity crowd funding platform, and different models of venture capital today.
