Intro to the Philosophy of Mathematics (Ray Monk)

source: Philosophical Overdose    2016年8月21日
A very good introductory talk on the philosophy of mathematics by Ray Monk. He considers the issue of the nature of mathematical truth, what mathematics is actually about, and discusses the views of Plato, Aristotle, Immanuel Kant, and Bertrand Russell...
From the time of Plato onwards, people have regarded mathematical truth as an ideal. Unlike ordinary, empirical truth, it is held that mathematical truth is eternal, incorrigible, and certain. This talk looks at the ways in which philosophers have tried to account for the special nature of mathematical truth.
Ray Monk is a British philosopher well known for his writings on Wittgenstein, Bertrand Russell, and the physicist J. Robert Oppenheimer.
This talk is part of the Philosophy Cafe series given at the University of Southampton. Subtitles/transcript have been added.

Frederic Myers & Psychical Research with Terence Palmer

source: New Thinking Allowed    2016年8月7日
Terence Palmer, PhD, is author of The Science of Spirit Possession. He is a member of the Society for Psychical Research as well as the Scientific and Medical Network. He is also a fellow of the Royal Society of Medicine.
Here he focuses on the research, largely in the nineteenth century, of the Society for Psychical Research. Frederic Myers great work, Human Personality and Its Survival of Bodily Death, was published in 1903 – two years after his death. In 2003, the British Psychological Association celebrated the 100th anniversary of its publication. Among other interests, Myers focused on the question of telepathic hypnotic induction. He also developed a theoretical model in which survival after death was shown to be part of a larger of spectrum of unusual experiences. Myers appears to have continued his research into human survival after his own demise. His communications to mediums on three different continents initiated the famous “cross-correspondence” series of communications that stand among the best evidence for survival of human personality.

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.

Stanford researchers discuss the ethics of autonomous vehicles

source: Stanford     2016年7月29日
To actually integrate autonomous vehicles into everyday life, researchers need to teach the cars how to make the safe driving decisions that come intuitively to human drivers. Stanford engineers are conducting experiments to translate social behavior into algorithms so that self-driving cars will maintain vehicle safety and passenger comfort.

Economy for the Common Good with Christian Felber

source: The RSA    2016年8月18日
Economy for the Common Good with economist and writer Christian Felber. Can businesses have both endless growth and be fair and sustainable? Is it possible to conceive an economic model that’s not tainted by our current financial system? Christian Felber’s initiative ‘Economy for the Common Good’ started in 2010 and is now supported by more than 2000 businesses from 40 countries. It aims to create change by awarding legal benefit points to socially responsible companies and encourage their pursuit of the common good. At the RSA, Christian Felber shows how we can achieve this systemic shift.

Mingming Yang: "From the Discovery of the Higgs boson To the Meaning of ...

source: Talks at Google    2016年8月2日
Experimental physicist Mingming Yang presents an overview of her work at the European Organization for Nuclear Research (CERN), culminating in the identification of the Higgs boson particle. In parallel, she explores her journey of self-discovery and the significance of science research to humankind. Throughout her experiences in a collaborative research environment, Mingming contemplates the role of the individual, the value of particle physics, and the beauty of nature. Mingming obtained PhD from MIT physics department last Septermber. Her work was searching for the Higgs boson through its decay into two photons at the Large Hadron Collider (LHC) in CERN, with the Compact Muon Solenoid detector (CMS) Higgs to Two Photon Working Group.

Can the Olympics Render Our Tribal Impulses Harmless? | Sebastian Junger

source: Big Think    2016年8月1日
The Olympics provide a place to celebrate national identity on an unparalleled scale, and rather than compete against each other maliciously, the games are an opportunity to showcase the beauty and nobility of competition. Junger's latest book is "Tribe: On Homecoming and Belonging" (http://goo.gl/k4hEeN).

Transcript - Sports are an interesting way for people who experience a collective identity. Sports teams in this country have their own sort of tribal impulses against each other. But then, you know, drop a few bombs on Pearl Harbor and then all of a sudden we’re one country facing an enemy. And people just naturally cohere into groups. And when you create a group just by necessity you’re also creating a whole bunch of people who aren’t in your group. And just mathematically know – that’s just a mathematical truth. And one of the interesting things about the Olympics is that it’s a chance for nations to demonstrate their nationness, to demonstrate the fact that they actually see themselves as a nation which is a beautiful thing. I mean that’s what we have organized ourselves into nations. That’s the modern world and when you see that on display it can be really moving. But it also because hopefully we’re sort of bigger than ourselves it also allows nations to entertain some kind of communalism between each other that’s sort of channeled through the ability of competition.
