Some of the world’s most recognizable symbols exist to sell products. Others, to steer traffic or advance political causes. But there’s one whose main purpose is to help people. You may know it as the wheelchair symbol, but its formal title is the International Symbol of Access. But what does the symbol actually mean? And what is its purpose? Adrian Treharne explains.

Theory of Computation (Fall 2011 at UC Davis) by Michael Sipser

source: UC Davis Academics    2014年10月17日
This is a rigorous undergraduate course on the Theory of Computation, using the classic text "Introduction to the Theory of Computation" by Michael Sipser. The course covers machine models and languages defined by Finite State Machines, Context-Free Languages, and Turing Machines.
There are four major theorems (and their uses) that we will study during this course, providing complete proofs: the pumping Lemma for regular languages, used to show that there are languages that are not regular; the existence of a Universal Turing Machine; undecidability of the Halting problem; and Cook's theorem that NP-complete problems exist. In addition to these major results, and other results, a central goal of the course is to increase student's skill level in understanding and writing rigorous mathematical proofs.

ARE139: Futures and Options
This course focuses on the institutional structure and economic functions of futures and options markets. Price formation in both commodity (e.g., corn, crude oil, cotton, and cattle) and financial (e.g., Eurodollar, Treasury Bonds, and stock indexes) futures and options markets will be examined in detail. The theory and practice of hedging will be explored in depth. Additional topics include: the theory of inter-temporal price formation for commodities and financials, common approaches used to forecast prices, statistical analysis of historical price behavior, and futures and options market regulation.

Lecture 1 starts with a broad outline of the course. Carter discusses the history and basic principles of futures markets. 1:22:01

Tim Wu: "The Attention Merchants" | Talks at Google


source: Talks at Google    2016年12月13日
Tim is an author, policy advocate, and professor at Columbia University, best known for coining the term "net neutrality." In 2006, Scientific American named him one of 50 leaders in science and technology; in 2007, 01238 magazine listed him as one of Harvard's 100 most influential graduates; in 2013, National Law Journal included him in "America's 100 Most Influential Lawyers"; and in 2014 and 2015, he was named to the "Politico 50." He formerly wrote for Slate, where he won the Lowell Thomas Gold medal for Travel Journalism, and is a contributing writer for The New Yorker.
THE ATTENTION MERCHANTS provide a revelatory look at the rise of "attention harvesting," and its transformative effect on our society and our selves. It serves as an illuminating, urgent look at how businesses commodify our attention, and what we lose when we give it to them.

The Reality of Possibility with Ruth E. Kastner


source: New Thinking Allowed     2016年12月8日
Ruth Kastner, PhD, is a philosopher exploring the foundations of physics. She is on the faculty of the physics department at the State University of New York at Albany. She is also a research associate at the University of Maryland. She is author of The Transactional Interpretation of Quantum Mechanics: The Reality of Possibility and also Understanding Our Unseen World: Solving Quantum Riddles.
Here she describes Plato’s famous cave allegory, and suggests that it is relevant to our understanding of quantum mechanics. Specifically, she suggests that the higher dimensional mathematical formalisms, although not empirically observable, point toward very real levels of existence. To buttress her argument, she also describes the nineteenth century parable of Flatland. In quantum theory, there are the probability clouds described by the Shrödinger psi equation. At another, more subtle, but still ontologically real level, are virtual particles.

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. 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.

The Science of Happiness, Motivation, and Meaning | Dan Ariely


source: Big Think     2016年12月5日
It turns out there's quite a bit of cognitive dissonance impairing our understanding of motivation and happiness. Duke University's Professor Dan Ariely fills in the gaps. Ariely's latest book is "Payoff: The Hidden Logic That Shapes Our Motivations" (https://goo.gl/SkXk2p).

Transcript - So when we think about what motivates people maybe the first think about is what we think motivates people and what don’t we understand motivates people. And maybe the first misunderstanding is about the pleasure principle. So we have this idea of we have the right to pursue happiness and we’re trying to be happy and that’s really what we’re pursuing – happiness. But think about it. What gives you happiness in a way that is observable? Maybe sitting on the beach drinking a mojito or maybe sitting on the sofa watching a sitcom. But if you do almost anything that is useful, meaningful, that you take pride of it’s not the same things. But imagine you have a whole life of sitting on the beach drinking mojitos. How happy would that life be? So the first I think mistake is that we pursue momentary happiness rather than longer term happiness. So we do the things that will make us laugh out loud today kind of. Not always laugh out loud but kind of like that. And we don’t do the things that are difficult and complex and challenging but give us a very different sense of happiness. Think about something like running a marathon. You don’t see anybody happy. Like if you came as an alien and you image peoples’ brains and you looked at their facial expressions as they’re running a marathon you would say somebody’s punishing them.
