In the video below, inventor and author William Gurstelle offers instructions on building a simple chaos machine for classroom study or just for personal enjoyment.
More information is available here, and a computerized animation of a double pendulum is here.
Stephen Hawking is arguing that humanity may be putting itself in mortal peril by actively trying to contact aliens (an approach that is referred to as Active SETI). I’ve got five reasons why he is wrong.
The purpose of this episode of Cybernetik Free Radio is to address the difficult questions of Open Individualism, and explore its interesting and complex notions.

In a 21st century world of uneven growth, disruptive technology, climate danger, and chaotic politics, we must build a society that’s transparent, diverse and able to look ahead—and embracing a philosophy of resilience will help get us there.
In response to a flurry of interest that’s been stirred by Stephen Hawking’s new Discovery Channel show—specifically, his lead-in episode about extraterrestrials, wherein he recommended against our calling attention to ourselves—I’ll offer a hurried little riff here, about Hawking and aliens, with added contributions by and about Paul Davies, Robin Hanson, and others.
“The Unbroken Thread” is the fourth video in the Symphony of Science series, and it features David Attenborough, Jane Goodall, and Carl Sagan.

The themes present in “The Unbroken Thread” attempt to explore the wild diversity of life on our planet, the intricacy and origin of its mechanisms, and its close relation to all other life forms.
In some other places, the topic of legendary science fiction author Robert Anson Heinlein has repeatedly come up, along with shouting matches — “He was a libertarian!” “No, a socialist!” “No, a fascist!” — I’ve finally had enough and will weigh in.
Of the nearly 2,000 people who have signed up via Facebook to follow the activities of the Institute for Ethics and Emerging Technologies, New York is the city most represented, followed by Seattle, Atlanta, London, and Los Angeles.
(Hattip to io9) Paul Zak has shown that oxytocin supplementation can enhance interpersonal trust and trust in institutions. Social stressors may suppress oxytocin and trust, and lead to bad social outcomes. Read Zak’s Moral Molecule blog at Psychology Today.
Climate change is being felt the world over, and if global warming continues to increase, the effects could be catastrophic. This 2007 BBC program reports on scientists and engineers who are proposing radical, large-scale ideas that could, theoretically at least, save us from disaster.
Democracy ... capitalism ... communism ... socialism ... anarchism ... the list goes on and on ... is there any really good way to structure a human society? If not, then what’s the best of the bad lot?

This is my first attempt at video. It depicts my control (or lack thereof) of a variety of things, including india ink, watercolor, fire and water, and solid objects. Using the manipulation of digital film I create the ultimate illusion: the ability to control time itself!
