[history] Nick Griffin’s Bad Science … ‘Furthermore, Britain has never had an indigenous population, in the sense of people who evolved here. Every member of Homo sapiens who has ever lived in Britain has been either an immigrant, or the descendent of immigrants. The very first ones, the genetic evidence suggests, came here from an ancestral home in northern Spain or the Basque country.’

[space] The Hunt for Extraterrestrial Life Gets Weird … ‘For instance, Leitner said, we can send rovers to Mars carrying antibodies that detect traces of chemicals and bacteria that would indicate life. But because we can only make antibodies to known substances, this method will be limited to finding Earth-like life. “When we try to find a definition for life, in most cases, such a definition is more a summary of the specific properties of terrestrial life,” Leitner said. Because life on Earth requires water, most of the search for extraterrestrial life thus far has focused on the “habitable zone,” or the relatively narrow region around a star where liquid water could exist.’

[lists] The 10 Biggest Intellectual Fights Of All Time … On Galileo vs. The Church: ‘…in 1632 he published Dialogue Concerning the Two Chief World Systems and quickly found himself summoned to appear before the Inquisition on charges of heresy. Galileo was forced to recant his support for the Copernican model and spent the rest of his life under house arrest, though with rather lenient travel and visitation allowances. His works were finally dropped from the Index of prohibited books in 1835. In 1992 Pope John Paul II expressed regret for how the “Galileo Affair” was handled, officially conceding on the part of the church that the earth is not stationary and that the planets orbit the sun.’

[knowledge] Clive Thompson on How More Info Leads to Less Knowledge … ‘Normally, we expect society to progress, amassing deeper scientific understanding and basic facts every year. Knowledge only increases, right? Robert Proctor doesn’t think so. A historian of science at Stanford, Proctor points out that when it comes to many contentious subjects, our usual relationship to information is reversed: Ignorance increases. He has developed a word inspired by this trend: agnotology. Derived from the Greek root agnosis, it is “the study of culturally constructed ignorance.” As Proctor argues, when society doesn’t know something, it’s often because special interests work hard to create confusion…’

[twitter] It turns out it was Fake Richard Dawkins on Twitter … That said, Fake Richard Dawkins doesn’t seem all bad:
‘While I still have 1700 of you paying attention, I just wanted to say: Whatever you believe, respect others beliefs. It’s not wrong to be kind to people who don’t believe the same as you. You don’t have to be militant atheists. People who claim to be Christians can be hypocrites, but they’re just people, and all people make mistakes. Try to be good to one another. That is my message of peace to all of you. Love one another. It’s ok. Consider that being hostile towards others has never won any followers. Richard Dawkins is just an old man trying to leave behind a legacy. Just like I, a Chrisitan do not follow Jerry Falwell or Pat Robertson, don’t be mislead by someone just because they share your belief system. It’s easy to be against people who are different than you, but try not to be like that. Take the high road, unlike RD. Thanks for listening and following along. Have a nice day.’

[food] Dip Once or Dip Twice — a food microbiologist examines double dipping at parties as practiced by George in Seinfeld … ‘On average, the students found that three to six double dips transferred about 10,000 bacteria from the eater’s mouth to the remaining dip. Each cracker picked up between one and two grams of dip. That means that sporadic double dipping in a cup of dip would transfer at least 50 to 100 bacteria from one mouth to another with every bite.’ [via Kottke]

[dna] 23AndMe Will Decode Your DNA for $1,000. Welcome to the Age of Genomics — from Wired … ‘We will, counterintuitively, face even more pressure to conduct our lives carefully, strictly, and cautiously; we’ll practice the art of predictive diagnosis and receive a demanding roster of things to avoid, things to do, and treatments to receive — long before there’s any physical evidence of disease. And, yes, we will know whether our children are predisposed to certain traits or talents — athletics or music or languages — and encourage them to pursue certain paths. In short, life will become a little more like a game of strategy, where we’re always playing the percentages, trying to optimize our outcomes.’

[science] The Social Norm Of Leaving The Toilet Seat Down: A Game Theoretic Analysis … ‘In this paper, we internalize the cost of yelling and model the conflict as a non-cooperative game between two species, males and females.We find that the social norm of leaving the toilet seat down is inefficient. However, to our dismay, we also find that the social norm of always leaving the toilet seat down after use is not only a Nash equilibrium in pure strategies but is also trembling-hand perfect. So, we can complain all we like, but this norm is not likely to go away. All hope is not lost though…’ [via Sore Eyes]

[science] Yes, the universe looks like a fix. But that doesn’t mean that a god fixed it … ‘The impression of design is illusory: our universe has simply hit the jackpot in a gigantic cosmic lottery. The multiverse theory certainly cuts the ground from beneath intelligent design, but it falls short of a complete explanation of existence. For a start, there has to be a physical mechanism to make all those universes and allocate bylaws to them. This process demands its own laws, or meta-laws. Where do they come from?’

The couple regularly held dinner parties for the great and the good of Victorian science. But alongside this Emma recorded his blackouts, retching and flatulence that were features of his mystery illness. Her matter-of-fact style is perhaps most movingly evident in her entry on April 18 1882, the day of his death. She wrote simply: “Fatal attack at 12.”‘

Astronomers call this boundary the Kuiper cliff, because the density of space rocks drops off so steeply. What caused it? The only answer seems to be a 10th planet.

[film] Forgetfulness Of Things Past — Steven Rose on the possibility of erasing memories. ‘…an animal was taught a particular task, and then days later was reminded of it by being put in the same context, the memory became labile once more – that means it could be disrupted by protein synthesis inhibitors. It was as if the reminder not only reactivated the old memory, but resulted in an entirely new memory being formed on top of it. Of course, we can intuitively recognise this; when we recall a past event, we are not recalling the event per se, but our memory of it from the last time we recalled it. This is why our autobiographical memories are being reshaped as we go through life.’ [Related: Eternal Sunshine of the Spotless Mind]

[books] Clearing Up The Confusion — Neal Stephenson on his new book The Confusion. On Isaac Newton: ‘…the gist of it seems to be that Newton was trying to achieve some specific goals with alchemy. Some of those goals might have been religious, but many were clearly scientific. As a scientist, he knew that he could only explain so much with the tools that he was using, and that to advance beyond that point he was going to need a different toolbox. He recognized that a lot of alchemy was nonsense, but he thought that by going about it in a systematic and rational way he’d be able to solve some scientific problems. He would have rejected the label of magician because it might have had dark connotations to him.’ [via yoz]

‘…experts believe there may have been many other big bangs, perhaps trillions and trillions of them, spread through the mighty span of eternity, and that the reason we exist in this particular one is that this is one we could exist in. As Edward P. Tryon of Columbia University once put it: “In answer to the question of why it happened, I offer the modest proposal that our Universe is simply one of those things which happen from time to time.”‘

‘What would he tell a stranger the book is about? “Without putting them off?” he asks with an uncertain smile. “That’s the difficult thing. Well it’s about how personal identity is fragile, and how at one level we’re basically meat and at another level we’re basically fiction – human beings are storytelling machines, and the self is a story, and we tell a story about ourselves, and we just pick up on the story.” He stops, defeated…’

[universe] God Is the Machine — Kevin Kelly wonders if the Universe is a computer … ‘If the universe is a computer, where is it running? Fredkin says that all this work happens on the “Other.” The Other, he says, could be another universe, another dimension, another something. It’s just not in this universe, and so he doesn’t care too much about it. In other words, he punts. David Deutsch has a different theory. “The universality of computation is the most profound thing in the universe,” he says. Since computation is absolutely independent of the “hardware” it runs on, studying it can tell us nothing about the nature or existence of that platform. Deutsch concludes it does not exist: “The universe is not a program running somewhere else. It is a universal computer, and there is nothing outside of it.”‘ [via Haddock]

[dna] DNA as Destiny — a Wired writer gets his DNA scanned for problems. ‘…the string of genetic letters from my mtDNA readout that indicates I’m mostly Celtic, which makes sense. But other bits of code reveal traces of Southeast Asian DNA, and even a smidgen of Native American and African. This doesn’t quite have the impact of discovering that I’m likely to die of a heart attack. Nor am I surprised about the African and Indian DNA, since my mother’s family has lived in the American South since the 17th century. But Southeast Asian? Sykes laughs. “We are all mutts,” he says. “There is no ethnic purity. Somewhere over the years, one of the thousands of ancestors who contributed to your DNA had a child with someone from Southeast Asia.”‘

[science] You Ask The Questions — Robert Winston … ‘Q: Is it true that your new series, ‘Human Instinct’, is going to explain — scientifically — why men have the urge to cheat on their partners? A: Well, the accompanying book goes into more detail. It’s because a woman’s egg is much more precious — she only produces one so it’s a huge investment. While the man produces millions of sperm that he can spread around. In the programme, we go round a university quad with a male and a female wearing a hidden camera asking the students whether they’ll sleep with them that night. All the women shy off immediately. And all the men look at their watches and say, “Yes, I’m free at 8.30”! It’s quite an important scientific point.’

Human behaviour seemed to be very unpredictable, whereas chemistry was the opposite.’

[tech] A couple of interesting articles from Steven Levy [thanks Kabir] …
Great Minds, Great Ideas — Levy on Stephen Wolfram and Dean Kamen … ‘“A New Kind of Science” is encyclopedic, a “Ulysses”-like text that applies Wolfram’s ideas to a wide range of subjects: physics, math, philosophy, robotics, economics, logic, even theology. One reason it took him so long is that he kept unearthing new discoveries in various fields. It became a joke among his assistants. “So you’re going to figure out some big thing in this field in the next couple of days?” they’d ask. And Wolfram would say, “Yes, that’s what I’m going to do.” And proceed to do it, at least on his terms.Some scientists aren’t exactly thrilled. “There’s a tradition of scientists approaching senility to come up with grand, improbable theories,” says physicist Freeman Dyson. “Wolfram is unusual in that he’s doing this in his 40s.”’
Will the Blogs Kill Old Media? — Levy on Blogs. ‘…once you’ve created your blog and filled it with links to news accounts of the Pim Fortuyn assassination, snarky criticisms of Bill O’Reilly and witty rants about airport security, how do you get visitors? Judging from the top blogs, the answer seems to be working hard, filling a niche, winning a reputation for accuracy, developing sources and writing felicitously. This sounds a lot like the formula to succeed as a journalist inside the Big Media leviathan. With the difference that traditional journalists uh, get paid. What makes blogs attractive — their immediacy, their personality and, these days, their hipness — just about ensures that Old Media, instead of being toppled by them, will successfully co-opt them. You might argue that it’s happened already.’

[film] Dinomania — Review of Jurassic Park from Stephen Jay Gould in 1993 … ‘…the mantle of carnivorous heroism has clearly passed to the much smaller Velociraptor, Henry Fairfield Osborn’s Mongolian jewel. Downsizing and diversity are in; constrained hugeness has become a tragic flaw. Velociraptor is everything that modern corporate life values in a tough competitor—mean, lean, lithe, and intelligent. They hunt in packs, using a fine military technique of feinting by one beast in front, followed by attack from the side by a co-conspirator. In the film’s best moment of wry parody of its own inventions, the wonderfully stereotyped stiff-upper-lip-British-hunter Muldoon gets the center beast in his gun’s sight, only to realize too late that the side-hunting companion is a few inches from his head. He looks at the side beast, says “Clever girl” in a tone of true admiration (all of Jurassic Park’s dinosaurs are engineered to be female in another ultimately failed attempt to control their reproduction), and then gets gobbled to death.’ [via Robot Wisdom]

[science] The Man Who Cracked The Code to Everything — Steven Levy on Stephen Wolfram. ‘…he’s saying that all we hold dear – our minds, if not our souls – is a computational consequence of a simple rule. “It’s a very negative conclusion about the human condition,” he admits. “You know, consider those gas clouds in the universe that are doing a lot of complicated stuff. What’s the difference [computationally] between what they’re doing and what we’re doing? It’s not easy to see.”‘
