I came across this video earlier tonight, and it (1) left me dumbfounded and (2) reminded me of how much I enjoyed riding my BMX as a teenager. I’m amazed by the advances made in street/trials riding, and this video of Danny MacAskill is a good example of how far a talented rider can push the limits of physics/sanity.

I caught this documentary a couple of weeks ago and it totally tickled my fancy (i didn’t really just say that).
In 1993, two dudes from NYC decided they would trace Marco Polo’s journey along the Silk Road, beginning and ending the trip in Venice, and traveling clear across Europe and Asia to the Pacific coast. However, unlike other modern attempts at recapitulating the famous explorer’s travels, these dudes committed themselves to land-and-sea travel only, and resolved to follow as faithful and accurate a path as possible, even if it necessitated traveling through early-90’s civil war-period Afghanistan, or purchasing pack animals to make it through threatening deserts and perilous mountain passes.
The Collider, the Particle and a Theory About Fate
More than a year after an explosion of sparks, soot and frigid helium shut it down, the world’s biggest and most expensive physics experiment, known as the Large Hadron Collider, is poised to start up again. In December, if all goes well, protons will start smashing together in an underground racetrack outside Geneva in a search for forces and particles that reigned during the first trillionth of a second of the Big Bang.
Then it will be time to test one of the most bizarre and revolutionary theories in science. I’m not talking about extra dimensions of space-time, dark matter or even black holes that eat the Earth. No, I’m talking about the notion that the troubled collider is being sabotaged by its own future. A pair of otherwise distinguished physicists have suggested that the hypothesized Higgs boson, which physicists hope to produce with the collider, might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather.
Holger Bech Nielsen, of the Niels Bohr Institute in Copenhagen, and Masao Ninomiya of the Yukawa Institute for Theoretical Physics in Kyoto, Japan, put this idea forward in a series of papers with titles like “Test of Effect From Future in Large Hadron Collider: a Proposal” and “Search for Future Influence From LHC,” posted on the physics Web site arXiv.org in the last year and a half.
According to the so-called Standard Model that rules almost all physics, the Higgs is responsible for imbuing other elementary particles with mass.
“It must be our prediction that all Higgs producing machines shall have bad luck,” Dr. Nielsen said in an e-mail message. In an unpublished essay, Dr. Nielson said of the theory, “Well, one could even almost say that we have a model for God.” It is their guess, he went on, “that He rather hates Higgs particles, and attempts to avoid them.”
This malign influence from the future, they argue, could explain why the United States Superconducting Supercollider, also designed to find the Higgs, was canceled in 1993 after billions of dollars had already been spent, an event so unlikely that Dr. Nielsen calls it an “anti-miracle.”
You might think that the appearance of this theory is further proof that people have had ample time — perhaps too much time — to think about what will come out of the collider, which has been 15 years and $9 billion in the making.
The collider was built by CERN, the European Organization for Nuclear Research, to accelerate protons to energies of seven trillion electron volts around an 18-mile underground racetrack and then crash them together into primordial fireballs.
For the record, as of the middle of September, CERN engineers hope to begin to collide protons at the so-called injection energy of 450 billion electron volts in December and then ramp up the energy until the protons have 3.5 trillion electron volts of energy apiece and then, after a short Christmas break, real physics can begin.
Maybe.
Dr. Nielsen and Dr. Ninomiya started laying out their case for doom in the spring of 2008. It was later that fall, of course, after the CERN collider was turned on, that a connection between two magnets vaporized, shutting down the collider for more than a year.
Dr. Nielsen called that “a funny thing that could make us to believe in the theory of ours.”
He agreed that skepticism would be in order. After all, most big science projects, including the Hubble Space Telescope, have gone through a period of seeming jinxed. At CERN, the beat goes on: Last weekend the French police arrested a particle physicist who works on one of the collider experiments, on suspicion of conspiracy with a North African wing of Al Queda.
Dr. Nielsen and Dr. Ninomiya have proposed a kind of test: that CERN engage in a game of chance, a “card-drawing” exercise using perhaps a random-number generator, in order to discern bad luck from the future. If the outcome was sufficiently unlikely, say drawing the one spade in a deck with 100 million hearts, the machine would either not run at all, or only at low energies unlikely to find the Higgs.
Sure, it’s crazy, and CERN should not and is not about to mortgage its investment to a coin toss. The theory was greeted on some blogs with comparisons to Harry Potter. But craziness has a fine history in a physics that talks routinely about cats being dead and alive at the same time and about anti-gravity puffing out the universe.
As Niels Bohr, Dr. Nielsen’s late countryman and one of the founders of quantum theory, once told a colleague: “We are all agreed that your theory is crazy. The question that divides us is whether it is crazy enough to have a chance of being correct.”
Dr. Nielsen is well-qualified in this tradition. He is known in physics as one of the founders of string theory and a deep and original thinker, “one of those extremely smart people that is willing to chase crazy ideas pretty far,” in the words of Sean Carroll, a Caltech physicist and author of a coming book about time, “From Eternity to Here.”
Another of Dr. Nielsen’s projects is an effort to show how the universe as we know it, with all its apparent regularity, could arise from pure randomness, a subject he calls “random dynamics.”
Dr. Nielsen admits that he and Dr. Ninomiya’s new theory smacks of time travel, a longtime interest, which has become a respectable research subject in recent years. While it is a paradox to go back in time and kill your grandfather, physicists agree there is no paradox if you go back in time and save him from being hit by a bus. In the case of the Higgs and the collider, it is as if something is going back in time to keep the universe from being hit by a bus. Although just why the Higgs would be a catastrophe is not clear. If we knew, presumably, we wouldn’t be trying to make one.
We always assume that the past influences the future. But that is not necessarily true in the physics of Newton or Einstein. According to physicists, all you really need to know, mathematically, to describe what happens to an apple or the 100 billion galaxies of the universe over all time are the laws that describe how things change and a statement of where things start. The latter are the so-called boundary conditions — the apple five feet over your head, or the Big Bang.
The equations work just as well, Dr. Nielsen and others point out, if the boundary conditions specify a condition in the future (the apple on your head) instead of in the past, as long as the fundamental laws of physics are reversible, which most physicists believe they are.
“For those of us who believe in physics,” Einstein once wrote to a friend, “this separation between past, present and future is only an illusion.”
In Kurt Vonnegut’s novel “Sirens of Titan,” all of human history turns out to be reduced to delivering a piece of metal roughly the size and shape of a beer-can opener to an alien marooned on Saturn’s moon so he can repair his spaceship and go home.
Whether the collider has such a noble or humble fate — or any fate at all — remains to be seen. As a Red Sox fan my entire adult life, I feel I know something about jinxes.
R.I.P. SACE

Hard-living, cop-dodging New York collage artist, photographer, and graffiti writer Dash Snow has died of a drug overdose at 27. Gawker broke the news this morning and now the Times has received confirmation from Snow’s grandmother, art collector Christophe de Menil, that he passed away last night at downtown hotel Lafayette House. According to De Menil, he’d been in rehab in March and had only recently started using again.
Snow became an emblem of the downtown art scene after being profiled by Ariel Levy in a 2007 New York cover story. In it, a friend of the artist told Levy his wall was lined with alphabetized binders cataloguing Snow’s work, “because you never know what’s going to happen with Dash.” He co-founded Irak, an infamous graffiti crew, and decorated much of his penis-obsessed artwork with his own semen — an interesting career path considering the pedigree of his family, which he claimed to have shunned following a two-year stint in juvenile detention between the ages of 13 to 15. In 2007, Levy wrote:
What makes the legend richer is that Dash Snow could very easily have lived a different kind of life, been a different kind of artist. Snow’s maternal grandmother is a De Menil, which is to say art-world royalty, the closest thing to the Medicis in the United States. His mother made headlines a few years ago for charging what was then the highest rent ever asked on a house in the Hamptons: $750,000 a season. And his brother, Maxwell Snow, is a budding member of New York society who has dated Mary-Kate Olsen.
As Levy notes in the piece, rebelling against one’s famous art family by becoming a famous artist may seem strange, but Snow — who was nearly as well known for his purported shoplifting and scuffles with the police — stumbled into it:
Snow refused to call himself an artist for a long time. He used to boast that he’d been Polaroiding his night wanderings since he stole a camera at age 13, just so he’d know where he’d been when he sobered up. More recently Snow has been into collage, but either way some see in his work a kind of radical authenticity that parts of the art world are desperate for. “Whether it’s total bullshit and he’s running around trying to get in trouble with the police, it kind of doesn’t matter,” says art agent and consultant Molly Logan. “As a case study, here’s a creature who’s just reacting. I think that for the last five years or so, there is a larger desire for the personal: something that has the hand of a person in it. It’s not I’m going to do this so people will think I’m crazy. I am crazy! I think he’s genuinely and completely self-destructive.”
Levy summarizes:
Which is, of course, what the art world has always wanted, especially in New York City, what Jackson Pollock or Willem de Kooning supplied, along with genius. That magic flash of insanity, framed and for sale.

Published on the Physicians For a National Health Program site a year-and-a-half ago, the arguments posited (and myths debunked) in this article are more salient and timely than ever.
LOL.
The crash has laid bare many unpleasant truths about the United States. One of the most alarming, says a former chief economist of the International Monetary Fund, is that the finance industry has effectively captured our government—a state of affairs that more typically describes emerging markets, and is at the center of many emerging-market crises. If the IMF’s staff could speak freely about the U.S., it would tell us what it tells all countries in this situation: recovery will fail unless we break the financial oligarchy that is blocking essential reform. And if we are to prevent a true depression, we’re running out of time.

This looks really good and I’d like to see it sometime soon. This dude was a genius, definitely ahead of his time, and it’s a shame we lost him at such a young age.

The national debt… Not necessarily the sexiest topic, what with today’s headlines of bailouts, massive unemployment, frozen credit markets, and all the other goodies that come along with cataclysmic economic collapse. This program sheds some light on why we ought to be concerned about year-over-year increasing deficits and entitlement spending and our nation’s current ten (or thirteen?) trillion dollar national debt.
