Krzysztof Gajos, "Design and Discrimination"

source: Harvard University   2016年8月31日
The currently prevalent one-size-fits-all approach to designing digital products inadvertently - but inevitably - leads to discrimination by making some people systematically a little more likely to succeed than others. In his lecture, Prof. Krzysztof Gajos will first show how current design practice discriminates against people based on their motor abilities, their ability to perceive color, or their subjective perception of what is aesthetically pleasing. He will then present a Computer Scientist’s approach to this problem: algorithms that automatically personalize design to provide more equitable access to digital resources.

Brains are conscious. The heart is not. What does the brain do that the heart does not do? How does it come to be that brains generate inner subjective experience, the movies of our minds? Why do brains seem to be the only place where such mental magic occurs?

The Block Universe B-Theory of Time - Eternalism (Huw Price)

source: Philosophical Overdose    2013年10月17日
The ancient philosophical dispute between Heraclitus and Parmenides in many ways continues to this day. One side accepts temporal Becoming as real and fundamental, while the other side declares it a subjective illusion. According to the former, dynamic view, time is conceived of as something which objectively "flows". This seems to require a distinguished present moment which is always changing, and which is ontologically special in some sense. But on the static conception of time (i.e. the block universe), there's no real objective passage. And so past, present, and future events are all ontologically equal. There's no privileged present moment or "now" built into the universe on this view. The universe is conceived as eternal and unchanging.
If something is missing from the 'block universe' conception of time, what is it, exactly? In this introductory survey Huw Price distinguishes three possible answers to this question, all apparently independent of each other. However, while there are three possible exits from the block universe, Price argues that they all seem to be dead ends.
This talk was part of a conference on whether we need a physics of temporal passage. It was given as part of the project New Agendas for the Study of Time: http://newagendasstudyoftime.wordpres...

Understanding Polytheism with P. Sufenas Virius Lupus

source: New Thinking Allowed       2016年9月5日
P. Sufenas Virius Lupus (his spiritual name) is a practicing polytheist and scholar. He is author of A Serpent Path Primer, Ephesia Grammata: Ancient History and Modern Practice, The Phillupic Hymns, The Syncretisms of Antinous, and other devotional books. Under his legal name of Phillip Bernhardt-House, he is author of Werewolves, Magical Hounds, and Dog-Headed Men in Celtic Literature. He is on the social science faculty at Skagit Valley College in Mount Vernon, Washington.
Here he notes that, in actual practice, polytheistic traditions are similar to those of the Catholic Church with its many devotional rites regarding saints. As certain humans are elevated to sainthood, so various polytheistic traditions have elevated other humans to the status of deities. Ancient Roman and Greek polytheism also included elements of satire – and even materialism. He, personally, maintains a clear distinction between the Jungian notion of archetypes that psychologists often associate with the pantheons of ancient religions and the living presence of willful, non-corporeal entities that are the foundation of polytheistic engagement.

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 a past vice-president of the Association for Humanistic Psychology; and is the recipient of the Pathfinder Award from that Association for his contributions to the field of human consciousness exploration. 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.

Could we survive prolonged space travel? - Lisa Nip

Prolonged space travel plays a severe toll on the human body: microgravity impairs muscle and bone growth, and high doses of radiation cause irreversible mutations. As we seriously consider the human species becoming space-faring, a big question stands: even if we do break free from Earth’s orbit, can we adapt to the extreme environments of space? Lisa Nip examines our odds.

Abortion and Personhood: What the Moral Dilemma Is Really About | Glenn Cohen

source: Big Think    2016年9月17日
The reason for the cultural divide ignited by the Roe v. Wade decision is not necessarily that people have intractable opinions. Instead, the issue of abortion is a genuinely complex moral dilemma.
Read more at BigThink.com: http://bigthink.com/videos/glenn-cohe...

Transcript - In the 1970s we have the Roe v. Wade decision in the United States. It was a decision relating to a woman's right to have an abortion. It introduced the trimester framework. It basically allowed first trimester abortions, made it very difficult to have third trimester abortions. And essentially this was really met very quickly thereafter with the sort of backlash. And really the last 40/50 years of American history have more or less been a backlash against Roe v. Wade and an attempt to kind of criminalize abortion in all sorts of interesting ways without overturning the decision.
So that's kind of the legal playing field. I mean we can talk about some of the specifics, but the more interesting question I think is thinking about the morality of abortion. And I'll say that I think abortion is an extremely difficult question. So one of the first questions people have to think about is are fetuses persons? And that's a very important linguistic question, persons. I didn't say human beings. I didn't say alive. Those are three different issues. Something can be alive but not be a person. Your dog is a good example. You love your dog. It's a wonderful thing but it's not a person. Something can be human and potentially not be a person. Some people think the embryo, for example, before 14 days or stem cells being derived are members of the human species but may not be a person. So what do we mean by persons? We mean something that has a certain set of moral and/or legal rights, most important of which is a right against in viability. They can't be killed or destroyed or harmed without very good reason. And we have the attitude that we're all persons so we have an index case we're pretty clear we're persons and the question is who else is a person? Well to answer that you need to have a theory about what makes something a person. Read Full Transcript Here: https://goo.gl/Q7eemx.

Bryan Franklin & Michael Ellsberg: "The Last Safe Investment" | Talks at...

source: Talks at Google    2016年9月1日
Authors Bryan Franklin and Michael Ellsberg visited Google's office in Cambridge, MA to discuss their book, "The Last Safe Investment".
In this provocative book, the authors make a well-reasoned case that the traditional wealth accumulation model (save for decades and invest in 401(k)s, IRAs, and a home) no longer works. They propose instead a blueprint for building “true wealth”: the ability to generate not just financial value but also the experiences you cherish most—security, freedom, creative ex­pression, and love.

Bryan Franklin is an expert on rapid scaling in business and has helped seven com­panies grow to more than $1 billion in sales or valuation by coaching their CEOs on business strategy and leadership. Michael Ellsberg is the author of "The Education of Millionaires: Everything You Won’t Learn in College About How to Be Successful". He writes a blog on entrepreneurialism, career development, and education at Forbes.com.

Great Soul or Great Schemer? Exploring the Myth of Mahatma Gandhi - Bidisha Ray

source: SFU History     2013年11月5日
Mahatma Gandhi's name is synonymous with peace and saintliness almost everywhere on the planet. Yet in parts of postcolonial South Asia, Gandhi's life, politics, ideologies, and legacy have been the subject of considerable controversy and even violent denigration. How, then, should we remember Gandhi? Misogynist tyrant or freethinking radical? Self-absorbed kingmaker or farsighted statesman? Economic genius or utopian fantasist? By exploring some of the most popular myths surrounding the man and his work, Dr. Bidisha Ray will offer a fresh perspective on what Gandhi and Gandhi-isms may stand for.

BIDISHA RAY
Born and raised in Calcutta, Bidisha Ray holds degrees from the universities of Delhi, Jadvapur, York, and Machester. She has spent time teaching History and Politics as well as working with the British Cabinet Office in London. She is currently working on a book-length study entitled Contesting Respectability: Sexuality, Corporeality and Popular Culture in Colonial Bengal.
