Huge asteroid, named Toutatis, to fly past Earth tomorrow

Storytoutatis_1
“The largest asteroid ever known to pass near Earth is making a close celestial brush with the planet this week in an event that professional and backyard astronomers are watching closely…

On September 29, Toutatis will be within a million miles of Earth, or about four times the distance to the Moon.

No space rock this big will pass so close in the next century, scientists say. And while similarly large asteroids have hit the planet in the distant past, none so big have come so close since astronomers have had the means to notice them. Many smaller space rocks have been spotted much closer, even inside the orbit of the moon.”

Daniel Dennett on Paul Churchland

“To some observers, such as those of various mysterian persuasions, Paul and I are scarcely distinguishable, both happily wallowing in one ‘scientistic’ or ‘reductionistic’ swamp or another, taking our cues from cognitive scientists and unwilling or unable to begrudge even a respectful hearing to their efforts to throw shadows on the proceedings. For those who can see no significant difference between us, this essay will try to sharpen a few remaining disagreements, while at the same time acknowledging that in fact we are approaching harmony on a number of heretofore contested topics. I will try to close the gap further, much as I have always enjoyed his loyal opposition.”

M.C. Escher’s “Relativity” in LEGO®

Lego_relativity_1
“Unlike many of Escher’s other ‘impossible’ pictures (like ‘Ascending and Descending’) , there is actually no optical illusion involved here. Gravity seems to be working in three different directions simultaneously, but the picture shows a perfectly self-consistent physical scene. So modelling it should certainly be feasible. But while Escher’s picture has three different “up”s, LEGO isn’t quite so flexible…”

“The 1500+ pages archived on this site have been written over the past eight years and several more are added every week. Most are about English words and phrases—what they mean, where they came from, how they have evolved, and the ways in which people sometimes misuse them. A few others concern issues of grammar, style and punctuation.”

Very interesting site where you will learn things like what “makebate” means! Check it out.

The Looking Glass Wars

Alice
“A new version of Lewis Carroll’s classic tale Alice’s Adventures in Wonderland by first-time author Frank Beddor has already got several critics up in arms even before it has been published.

Mr Beddor, who produced gross-out movie There’s Something About Mary, and is a former world champion skier, has transplanted Alice into a modern and violent fantasy world that could have come straight out of a computer game…

Mr Beddor makes no apology for drawing on the many modern influences in his book, including films Star Wars and The Matrix.”

“Young readers will appreciate it – it’s quite violent but in context” says John McLay, book reviewer.

A Portrait of the Artist as a Young Girl

28arti
“This summer, she went from selling her work in a coffee shop to having her own gallery show.

After a local newspaper’s feature on her, about 2,000 people came for opening night – everyone from serious collectors to the artist’s preschool teacher. She earned more money than she could comprehend. The gallery owner said it was his most successful show ever and scheduled a second one for October.

So celebrate, the artist did. During a recent visit, she climbed on a big bouncing ball shaped like a frog, grabbed the handles and bounced around the house with laughter pealing and pigtails flying.

The artist is Marla Olmstead. She is 4…

In all, Marla has sold 24 paintings totaling nearly $40,000, with the prices going up. Her latest paintings are selling for $6,000. Some customers are on a waiting list.”

The Writer’s Tale

Chandospencil
“No literary life excites as much speculation or poses as many puzzles as that of William Shakespeare. The keen interest in Shakespeare’s biography that began in the 18th century is a natural byproduct of his preeminence in our culture.

For all his fame, however, there are few outright certainties. The paper trail that does exist teases and tantalizes. Scholars have records of Shakespeare’s birth in 1564, and mentions of his work in the theater. There is evidence of his unpaid taxes and legal quarrels, a few property transactions, and a will.

Indeed, it is more than scholars know about many of Shakespeare’s artistic contemporaries. But the overall narrative thread of Shakespeare’s life is frayed in many places, and broken completely in others.

Tying that thread back together is the goal of Stephen Greenblatt’s new biography, Will in the World: How Shakespeare Became Shakespeare (W.W. Norton). In the book, Mr. Greenblatt seeks to combine the scholarship that has made him a central figure in the world of literary theory with the demands of a popular audience.”

Hitchens, Sullivan, and treating reasons as causes

Via Norman Geras, playwright and writer Johann Hari has an interview with Hitchens on his apostasy from the Left. The case of Hitchens and the Left is one that’s been watched by larger and larger audiences since 9/11. I’ve had mixed feelings about Hitchens’ long before the war–for example, when he suggested that feminists should give up on the abortion issue, and when he insisted that the subjugation of the natives in the Western hemisphere was a good thing in the end (“deserving to be celebrated with great vim and gusto”), or his second rate (at his best moments) and hack (at the worst ones) takes on Edward Said these days.

But I have been wary of arguments that explain his positions on the war in terms of opportunism, alcoholism, some closeted homosexuality (as Alexander Cockburn came close to doing), or the natural evolution of Trotskyism. Personally, I’m anti-fascist in my politics (across the fascist spectrum for that matter, Islamism and Ba’athism, Hindu chauvinism and the inheritors of the Kach, what have you). But I do have disagreements with Hitchens about how the war should be fought, about those who are leading the fight, and have been skeptical whether the future and world they want to bring about is the one I want. But I do take Hitchens’s reasons for his positions to be genuine. Hari’s piece in the Independent takes Hitchens’ views seriously, too, lets Hitchens be (lefty) Hitchens.

“‘Look: inequalities in wealth had nothing to do with Beslan or Bali or Madrid,’ Hitchens says. ‘The case for redistributing wealth is either good or it isn’t – I think it is – but it’s a different argument. If you care about wealth distribution, please understand, the Taliban and the al Quaeda murderers have less to say on this than even the most cold-hearted person on Wall Street. These jihadists actually prefer people to live in utter, dire poverty because they say it is purifying. Nor is it anti-imperialist: they explicitly want to recreate the lost Caliphate, which was an Empire itself.'”

So too does this Marc Cooper post on Hitchens, inspired by the Independent article.

The comments to Cooper’s post did remind me of a discussion spurred by Matthew Ygelsias’s posts on Andrew Sullivan’s decision not to vote for Bush. Some had taken a post by Yglesias to suggest that Sullivan is opposing Bush because of Bush’s stance on gay marriage. Yglesias’s follow-up started quite a debate/discussion on the blogosphere.

“One thing you learn studying the philosophy of mind is the difference between a cause and a reason. Ask me why I’m a liberal, and I could give you two different sorts of answers. One would be based on reasons — I would present arguments as to why I think liberalism is the correct political theory and then say that I am a liberal because of liberalism’s correctness. Another would be based on causes — my parents were liberals, as were the overwhelming majority of people I grew up with and interacted with until the very recent past, and I never found a compelling reason to abandon the ideology of my youth, though I’ve certainly changed my views on various specific reasons.

Causal explanations are interesting, but ultimately it’s disrespectful to talk about people in causal terms. There can be no doubt that Bush’s Texas swagger has had a (causal) influence on my evaluation of him as a man and as a president, but that fact notwithstanding, the appropriate thing for those who may disagree with me about this or that is to evaluate my arguments — my reasons. Now I think it would be silly to deny that, in a causal sense, the FMA plays a larger role in Andrew’s thinking than in the thinking of most people . . . but this is a dehumanizing and ultimately fruitless line of inquiry. He, like everyone else, gives reasons for his views and if you disagree with him (or me) you ought to take issue with his (or my) arguments, not make silly ad hominem attacks.”

Very discourse ethical, to be Habermasian. But is it that simple? DeLong throws in a few qualifications.

“It may be immoral (‘disrespectful’) for some transcendental reason to analyze other Minds in terms of their causes rather than their reasons. But it is also counterproductive–at least, it is counterproductive for a Mind that is in the reach-true-conclusions business rather than in the yea-for-my-team! business. For it’s only by taking the reasons advanced by other Minds seriously that one has a chance of improving the quality of one’s thought. That is the key reason to pay attention to reasons rather than causes when analyzing other Minds.

In Andrew Sullivan, however, do we have a Mind as we have defined it?”

It seems to me anyway that there are a few reasons to point to causes, rather than reasons. First, we legitimately can and do point to causes to explain why people hold the views they do–ideology, in short. Is it disrespectful to suggest that a Nazi may hold the views s/he does because of their upbringing, being surrounded by racist and anti-Semitic propoganda, etc?

Second, we do also point to causes to suggest that the reasons that an adversary offers for or against one positions isn’t their motive for or against that position and that the audience shouldn’t trust their reasons as ones they would hold (though this is sort of weak). But this isn’t aimed at the speaker and is probably a bit Machiavellian in the way that all politics is.

Finally, we can offer causes as reasons to change or refine our beliefs; we do this with ourselves–at least if we’re honest–to see if we hold some position or another for something other than good reasons. In this vein, we can also offer causes to change someone of their own beliefs (though to be effective, the openness will have to be symmetrical), in a kind of social equivalent of therapy.

But read the debate around the web.

Branson’s move into space tourism

Spacplane It’s either the zietgeist or it’s just herding in both journalism and the blogosphere–
I lean toward the latter, but following on the post on flying cars below, there’s this from the BBC.

“The news that Sir Richard Branson has signed a deal to take paying passengers into space suggests the Ansari X-Prize has achieved its goal of bringing space tourism closer to the masses. One of the aims behind the $10m (£5.7m) challenge was to galvanise enthusiasm for private manned spaceflight, thereby bringing ‘out of this world’ tourism within reach of ordinary people.

In the past, space travel has been open only to the privileged few; either government-back astronauts or millionaires with enough spare cash to book a flight on a Russian Soyuz rocket to the International Space Station.

If and when the Virgin venture – dubbed Virgin Galactic – begins offering its first spaceflights, the tickets will still be expensive. A sub-orbital flight is expected initially to cost about £100,000.”

Hemingway Bullfight Tale From 1924 Turns Up

27hemi1
“Eighty years after they were written, a previously unknown story and a handwritten letter ascribed to Ernest Hemingway have surfaced to stir a literary and legal dispute between people who want to see them published and people who don’t.

At present, the opponents of publication – notably the custodians of the Hemingway estate – are winning, according to several people on both sides of the debate. But that has not detracted from the long, twisty tale of the documents themselves: a two-page letter and a five-page slapstick account of a bullfighting incident written in 1924. Not only do the documents offer an insight into the personality of a young Hemingway, scholars say, but they also illuminate the powerful appeal exerted by even modest discoveries of previously unknown writing by literary giants like Hemingway, who died in 1961.”

More here from the New York Times. The passport photo of Hemingway is from around the time that he wrote the story (1923).

The academic uses of blogging

In keeping with the self-referential character of the blogosphere, a recent post and article has pointed to one use of blogs that I hadn’t considered.

Majikthise has a post on Quine; it’s a defense of Epistemology Naturalized. The post seems quite sensible, but the post is also interesting in light of what she does and one apparent reason for it.

“Currently, I’m collaborating on a moral psychology experiment about ordinary speaker’s use of the term ‘intentionally’. I’m also working on a paper about Quine, analyticity and gay marriage, a philosophical analyss of ‘media bias’ arguments, and some other more traditional projects.”

It ends with “I’d be very grateful for feedback on the above sketch.”

It may point a growing trend, the use of blogs for academic research. This Guardian piece discusses the trend.

“Creating a blog to track the progress of your PhD thesis might seem like the ultimate delaying tactic – a way to avoid ever actually writing the thing itself. But for Esther MacCallum-Stewart, currently doing a D.Phil thesis on popular culture during the first world war at the University of Sussex, the opposite has been true. She began blogging about her thesis (www.whatalovelywar.co.uk/war/) in February 2002, initially to keep track of the ideas she was developing. ‘I realised I was making notes all over the place, and they weren’t making any sense at all.'”

The trend seems very related to what you find in academic blogs such as Brad DeLong’s Semi-Daily Journal, Crooked Timber, and a Fistful of Euros–often thoughtful discussions of issues but in a format that lets you track and search them easily. It’s an altogether different type from the references/filters of Arts and Letters Daily or SciTechDaily, and from the passing but definitive judgment without argument (often with failed wit of the “Sontag Award Nominee” sort) one finds in Andrew Sullivan or Wonkette. All in all, a positive trend, I would say.

AIDS: The Elusive Vaccine

“After twenty-three years of intense research into the human immunodeficiency virus (HIV), together with the accumulated experience of more than twenty million deaths from the in-fection worldwide, there is still no prospect of a vaccine to prevent AIDS. Is the discovery of a vaccine simply a matter of time? Or has this virus presented scientists with a hitherto underestimated, perhaps even impossible, challenge?”

All the World’s a Gallery

Storey_1
“Two years ago, a sticker depicting Che Guevara as a ‘Star Wars’-style storm trooper began cropping up around Los Angeles, pasted to the backs of mailboxes and street signs. Inspired partly by the popular duotone Che portrait marketed on T-shirts and posters, the image seemed an amalgam of two of the most iconic images of the last half-century…

Inspired by graffiti, posters and the communal culture of the Web, stickers are gaining wide attention as an artistic phenomenon, academics and practitioners say. Hand-drawn, stenciled or screen-printed, the images float on the Internet, available for downloading, printing and pasting in ways that the creators could only have imagined. And as they make their way around the globe, from one e-mail in-box to the next, one cultural context to another, their meaning tends to morph.”

The Genesis Project

“One morning, a little more than a year from now, a group of scientists, members of what is known as the Stardust mission, will be standing around on a remote stretch of salt flat in the Utah desert, eagerly awaiting the arrival of a very special package. It will, if all goes as planned, enter our atmosphere much like a meteorite, plunging earthward until the final stage of re-entry, when a small parachute will open. The object, about the size and overall appearance of a large metal cephalopod mollusk, better known as the nautilus, will drift harmlessly to the ground, its belly filled with the dust and debris gathered from the comet Wild 2, which scientists now expect may offer significant clues about life’s origins here on earth…

Searching for the origins of life in the dust of a comet might sound like a bit of cosmically cockeyed indirection, something straight out of a New Age sci-fi novel. The Stardust mission, however, is typical of a number of projects to divine life’s origins, all part of a $75-million-a-year scientific enterprise now being financed by NASA. It is known as astrobiology.”

Why are lightning bolts jagged instead of straight?

000d0d6167ad1f04ba6a80a84189eedf_2
“Ever since Benjamin Franklin’s time lightning has been understood to be a large electrical discharge similar to that seen when a conductive object (like a metal doorknob) is touched after a static electric charge is picked up (by feet scuffing across carpet, for example). But whereas the spark from static electricity measures a centimeter or less in length, a lightning channel can span five kilometers or more. (Also, cloud-to-ground lightning involves electrical currents on the order of tens of thousands of amps. In contrast, a circuit breaker for a common household circuit is usually rated at 20 amps.) Because of its extreme scale, lightning is a complex physical phenomenon.”

NASA developing flying cars

26fly2
“Not only is NASA developing its own flying cars, but it’s also working on a collision-deterring navigation system that could make skyways safer than highways.

‘You can say our goal is to make the second car in every driveway a personal air vehicle,’ says Andrew Hahn, an analyst at NASA’s Langley Research Center in Hampton, Va. Hahn’s engineers are already committed to a 15-year time line for three successive generations of flying cars. The first will resemble a compact Cessna with folding wings that converts to road use; it should be available as a graduation gift when this year’s freshman class leaves high school. The second, with a rollout planned for 2015, is a two-person pod with small wings and a rear-mounted propeller. The third will rise straight up like a mini-Harrier jet and should be on the market by the time your newborn has a learner’s permit. The first of the three vehicles shouldn’t cost more than a Mercedes.”

Goodbye Darkness: The new science of exuberance

“What does the good life feel like? I mean the life worth living, the life we should and do admire. For most of the last century, that question was answered in terms derived from the study of depression, schizophrenia, and the anxiety disorders. A person in touch with the times would suffer existential angst and social anomie. To be wise was to experience ambivalence about important matters and to feel alienated from the culture.

If I am reading the tea leaves right, our fascination with emotional paralysis may be nearing an end.”
