John O'Keefe: "The GPS of the Brain" | Talks at Google


source: Talks at Google   2016年12月20日
Nobel Laureate John O’Keefe visits the GooglePlex to talk about Place Cells, the “GPS of the Brain”. A discovery for which he received the 2014 Nobel Prize in Medicine.
He explains how animals and humans find their way - by working out the relationship between where they are and where other things are. The brain does this by representing places (where you are now), and representing distances and directions. O'Keefe and his colleagues established which part of the brain does this, and how it works. Your brain has cells that represent places; so when you are in a familiar environment different cells represent different locations in this environment. There are cells that represent directions, for where you are looking and where you are moving; and there are also cells that tell the distances moved in particular directions. All this together forms a so called "cognitive map", which is a framework for identifying where you are, where other things are in your environment, and how to get from one place to another.

O’Keefe is a Neuroscientist and Professor at University College London. But he was born in Harlem, NY, the son of immigrant parents. He grew up in the Bronx, studied aeronautical engineering at New York University (yes, he’s an engineer made good!), and later attended City College of New York, the last free public college in the US, where he studied philosophy of the mind. He then did an MA and PhD in physiological psychology.

The mathematics of sidewalk illusions - Fumiko Futamura


source: TED-Ed    2017年1月23日
View full lesson here: http://ed.ted.com/lessons/the-mathema...
Have you ever come across an oddly stretched image on the sidewalk, only to find that it looks remarkably realistic if you stand in exactly the right spot? These sidewalk illusions employ a technique called anamorphosis — a special case of perspective art where artists represent 3D views on 2D surfaces. So how is it done? Fumiko Futamura traces the history and mathematics of perspective.

Noam Chomsky and Peter Singer on Abortion


source: LennyBound 2009年6月6日
These clips are taken from the 2006 Tony Kaye documentary "Lake of Fire" that graphically depicts the contemporary abortion debate in the United States.
Noam Chomsky is professor emeritus of linguistics at the Massachusetts Institute of Technology (MIT), and is one of the fathers of modern linguistics. Since the 1960s, he has become known more widely as a political dissident, an anarchist, and libertarian socialist.
Peter Singer is the Ira W. DeCamp Professor of Bioethics at Princeton University, and laureate professor at the Centre for Applied Philosophy and Public Ethics (CAPPE), University of Melbourne. He specializes in applied ethics, approaching ethical issues from a secular utilitarian perspective.

Peter Singer's Ethics


source: Eidos84    2010年11月27日
In this short clip Peter Singer discusses the ethics of poverty and affluence, animal rights, and the radical nature of applied ethics.

Peter Singer On Poverty


source: Eidos84 2010年10月30日
In this short clip Peter Singer draws on ideas from his "Singer Solution to World Poverty" article, and discusses arguments for why we should help people living in absolute poverty.

Peter Singer - Ethics, Utilitarianism & Effective Altruism


source: Adam Ford    2014年9月6日
Blog Post: http://www.scifuture.org/peter-singer...
In his 2009 book 'The Life You Can Save', Singer presented the thought experiment of a child drowning in a pond before our eyes, something we would all readily intervene to prevent, even if it meant ruining an expensive pair of shoes we were wearing. He argued that, in fact, we are in a very similar ethical situation with respect to many people in the developing world: there are life-saving interventions, such as vaccinations and clean water, that can be provided at only a relatively small cost to ourselves. Given this, Singer argues that we in the west should give up some of our luxuries to help those in the world who are most in need.

Around this central idea a new movement has emerged over the past few years known as Effective Altruism, which seeks to use the best evidence available in order to help the most people and do the most good with the limited resources that we have available. Associated with this movement are organisations such as GiveWell, which evaluates the relative effectiveness of different charities, and Giving What We Can, which encourages members to pledge to donate 10% or more of their income to effective poverty relief programs.

The Future of Food: Feeding the Planet During Climate Change


source: Harvard University    2016年12月15日
By 2050, a projected 9.7 billion people will inhabit the planet. How will we produce enough nutritious food to support this burgeoning population and ensure access to food resources, particularly as climate change stresses the environment? This Forum explored innovative methods and systems for producing food, as well as new types of products and underutilized sources. The panelists talked about emerging technologies, including advances in genomics and aeroponics, to grow food. They also discussed ways to sustain at-risk food resources made vulnerable from climate change, and the impacts for populations in developing countries.
Part of The Andelot Series on Current Science Controversies, this event was presented jointly with PRI's The World and WGBH on December 13, 2016.

Speaker(s): Dr David Rand
Chair: Dr Bradley Franks
Recorded on 8 December 2016 at Hong Kong Theatre, Clement House
Cooperation is central to successful human societies. But why are people willing to incur the individual costs involved in cooperating?

David Rand (@DG_Rand) is an Associate Professor of Psychology, Economics, and Management at Yale University, and the director of Yale University’s Human Cooperation Laboratory.
David's work has been published in peer-reviewed journals such Nature, Science, Proceedings of the National Academy of Science, Psychological Science, the American Economic Review, Journal of Experimental Psychology: General, and Management Science, and has received widespread attention from print, radio and TV outlets. He has also written popular press articles for the New York Times, Wired, New Scientist, and the Psychological Observer. He was named to Wired magazine’s Smart List 2012 of “50 people who will change the world,” chosen as a 2012 Pop!Tech Science Fellow, and received the 2015 Arthur Greer Memorial Prize for Outstanding Scholarly Research, and his papers have been awarded Best Paper of the Year in Experimental Economics, Social Cognition, and Political Methodology.
Bradley Franks is Associate Professor of Psychology in the Department of Psychological and Behavioural Science at LSE. He has interests in the intersections between culture, evolution and cognition, and has researched a variety of topics within this field, including the self, agency, varieties of knowledge representation and categorisation. His books include The Social Psychology of Communication (with D Hook & M Bauer, Palgrave MacMillan, 201), and Cognition and Culture: Evolutionary Perspectives (Palgrave MacMillan, 2011).
The Department of Psychological and Behavioural Science (@PsychologyLSE) study and teach societal psychology: the psychology of humans in complex socio-technical systems (organisations, communities, societies). Our research deals with real-world issues, we train the future global leaders.
