Seth Lloyd—LIFE: WHAT A CONCEPT!

An Edge Special Event at Eastover Farm
[8.27.07]

"If you program a computer at random, it will start producing other computers, other ways of computing, other more complicated, composite ways of computing. And here is where life shows up. Because the universe is already computing from the very beginning when it starts, starting from the Big Bang, as soon as elementary particles show up. Then it starts exploring — I'm sorry to have to use anthropomorphic language about this, I'm not imputing any kind of actual intent to the universe as a whole, but I have to use it for this to describe it — it starts to explore other ways of computing."

Craig Venter—LIFE: WHAT A CONCEPT!

An Edge Special Event at Eastover Farm
[8.27.07]

"One question is, can we extrapolate back from this data set to describe the most recent common ancestor. I don't necessarily buy that there is a single ancestor. It’s counterintuitive to me. I think we may have thousands of recent common ancestors and they are not necessarily so common."

Dimitar Sasselov—LIFE: WHAT A CONCEPT!

An Edge Special Event at Eastover Farm
[8.27.07]

"Is Earth the ideal planet for life? What is the future of life in our universe? We often imagine our place in the universe in the same way we experience our lives and the places we inhabit. We imagine a practically static eternal universe where we, and life in general, are born, grow up, and mature; we are merely one of numerous generations."


 

Master Class 2007: A Short Course In Thinking About Thinking

[7.18.07]

"I'll start with a topic that is called an inside-outside view of the planning fallacy. And it starts with a personal story, which is a true story."


 

RECURSION AND HUMAN THOUGHT

WHY THE PIRAHÃ DON'T HAVE NUMBERS
[6.11.07]

"As I look through the structure of the words and the structure of the sentences, it just becomes clear that they don't have recursion. If recursion is what Chomsky and Mark Hauser and Tecumseh Fitch have called 'the essential property of language', the essential building block—in fact they've gone so far as to claim that that might be all there really is to human language that makes it different from other kinds of systems—then, the fact that recursion is absent in a language — Pirahã — means that this language is fundamentally different from their predictions."

Robert Shapiro— LIFE: WHAT A CONCEPT!

An Edge Special Event at Eastover Farm
[5.9.07]

"I'm always running out of metaphors to try and explain what the difficulty is. But suppose you took Scrabble sets, or any word game sets, blocks with letters, containing every language on Earth, and you heap them together and you then took a scoop and you scooped into that heap, and you flung it out on the lawn there, and the letters fell into a line which contained the words “To be or not to be, that is the question,” that is roughly the odds of an RNA molecule, given no feedback — and there would be no feedback, because it wouldn't be functional until it attained a certain length and could copy itself — appearing on the Earth."

THE GOSPEL OF JUDAS

[4.28.07]

"This text sees Judas dying as a martyr—because here the other disciples hate him so much that they kill him! But the Gospel of Judas challenges the idea that God wants people to die as martyrs—just as it challenges the idea that God wanted Jesus to die. Whoever wrote this gospel—and the author is anonymous—is challenging church leaders who teach that. It's as if an imam were to challenge the radical imams who encourage "martyrdom operations" and accuse them of complicity in murder—the Gospel of Judas shows "the twelve disciples"—stand-ins for church leaders—offering human sacrifice on the altar—and doing this in the name of Jesus! Conservative Christians hate gospels like this—usually call them fakes and the people who publish them (like us) anti Christian. There was a great deal of censorship in the early Christian movement—especially after the emperor became a Christian, and made it the religion of the empire—and voices like those of this author were silenced and denounced as "heretics" and "liars." The story of Jesus was simplified and cleaned up—made "orthodox.""

GOD VS. SCIENCE: A Debate Between Natalie Angier and David Sloan Wilson, Moderated by Thomas A. Bass

[12.30.06]

"I see some fundamental contradiction here. Everybody criticizes Richard Dawkins and Sam Harris. But at least they're talking about how ludicrous some of these belief systems are. I know that David Sloan Wilson doesn't take issue with the way I've framed these questions, but to see religion as having a positive influence does not get at the fundamental question of what it means to have faith. What is so good about having faith when you don't have evidence?"
— Natalie Angier

"With apologies to Natalie, I think there's a kind of a silliness to banging away at religious beliefs for their obvious falsehood, when in fact, if you're an evolutionist, the only way you would want to evaluate these beliefs is to examine what they cause people to do." — David Sloan Wilson

THE ENERGY OF EMPTY SPACE THAT ISN'T ZERO

[7.5.06]

"I invited a group of cosmologists, experimentalists, theorists, and particle physicists and cosmologists. Stephen Hawking came; we had three Nobel laureates, Gerard 'tHooft, David Gross, Frank Wilczek; well-known cosmologists and physicists such as Jim Peebles at Princeton, Alan Guth at MIT, Kip Thorne at Caltech, Lisa Randall at Harvard; experimentalists, such as Barry Barish of LIGO, the gravitational wave observatory; we had observational cosmologists, people looking at the cosmic microwave background; we had Maria Spiropulu from CERN, who's working on the Large Hadron Collider — which a decade ago people wouldn't have thought it was a probe of gravity, but now due to recent work in the possibility of extra dimensions it might be."

AN EPIDEMIOLOGY OF REPRESENTATIONS

[7.26.05]

"How do the microprocesses of cultural transmission affect the macro structure of culture, its content, its evolution? The microprocesses, the small-scale local processes I am talking about are, on the one hand, psychological processes that happen inside people's brains, and on the other hand, changes that people bring about in their common environment — for instance the noise they make when they talk or the paths they unconsciously maintain when they walk — and through which they interact."
