Publishing Failure

Friday, May 8th, 02009



Bragging about failure rarely gets a professor tenure, or makes a scientist famous.  However it is failure by which we all learn the most from.  The video above where Brian Cox discusses the first failure at the LHC is an excellent example of how interesting failure can be.The benefits of publishing negative or ‘inconsequential’ data has a dotted but successful past.  It was the partially successful results of early HIV drugs that, in combination, gave us the successful HIV cocktail treatments.  It was the baseline data of background CO2 levels from a Hawaiian volcano that gave us the first warnings of how CO2 is linked to Global Warming with the Keeling Curve.  It is the spectacular and catastrophic failure of the Tacoma Narrows bridge that made engineering around constructive resonance the default. I hope somday to create a Museum of Failure, but until then, we have YouTube…


Modern code cracking adventures with ancient Indus Valley Script suggest it represents spoken language

 Indus Valley Script

In an article published in the April 24 issue of Sciences, researchers describe how they applied a computational process called “comparative entropy” to a corpus of ancient Indus Valley Script texts.  The results of the analysis show a kind of patterning they argue is only found in glottographic, or speech-based, writing systems.  The complex Indus Valley civilization flourished from 2,600 to 1,900 B.C. and left hundreds of engravings on seals and tablets — writings which have yet to be deciphered.

Members of the AAAS can read the Science article online here.  Otherwise this Asia Times Online article has a summary that describes historical attempts at identifying the script that would rival the storied Rosetta Stone.

10,000 Years of Beef

Thursday, April 23rd, 02009

 The Washington Post is carrying an interesting story on the recently completed cow genome: “Cow’s DNA Sequence Reveals Mankind’s Influence Over Last 10,000 Years.” Most interesting is what was learned by looking closely at such a domesticated beast.  The scientists were able to clearly see where selective breeding has radically changed the animal that we now recognize as a cow.  And did I mention that the name of the cow is Dominette, how great is that?

Hidden in her [the cow below named L1 Dominette 01449] roughly 22,000 genes are hints of how natural selection sculpted the bovine body and personality over the last 60 million years, and how man greatly enhanced the job over the last 10,000.

Computers, Clocks, Astronomy and The Making of the Modern World

Sunday, March 29th, 02009




Long Now member and close friend Susan Shea sent me this astoundingly good episode of James Burke’s “Connections”show from 01978 (It is in 5 parts).  It is the best tracing of computing technology through time and culture I have ever seen, and shows the lineage of ancient clocks to modern computers (if a computer in 01978 can be called modern, but you get the idea.) This also reminded me how good this TV show was, now I have to watch the other episodes…

The funeral for analog news… by Clay Shirky

Saturday, March 14th, 02009

A multitude of tweets from people like Tim O’Reilly and Nion McEvoy pointed me to this excellent piece on the end of analog news by (past seminar speaker) Clay Shirky.  Not to be missed, here is an excerpt:

“When someone demands to know how we are going to replace newspapers, they are really demanding to be told that we are not living through a revolution. They are demanding to be told that old systems won’t break before new systems are in place. They are demanding to be told that ancient social bargains aren’t in peril, that core institutions will be spared, that new methods of spreading information will improve previous practice rather than upending it. They are demanding to be lied to.

There are fewer and fewer people who can convincingly tell such a lie.”

I guess Long Now should start planning our next technological funeral event.  The funeral for the analog newspaper.

Outdoor Exploratorium at Fort Mason

Wind-powered Lift Exhibit
The new Outdoor Exploratorium at Fort Mason opens on Friday, March 13, 02009. Over 2 years in the making, these 20 permanent interactive science exhibits and artworks offer a deeper connection for the viewer to the surrounding landscape through scientific principles of observation and experimentation.The San Francisco Chronicle has a great article on the Outdoor Exploratorium.

The Kessler Syndrome

Friday, February 27th, 02009

The recent collision of two satellites in orbit represents a pretty serious problem for proponents of spaceflight.  Some scientists are discussing ways of cleaning up the increasing amounts of debris in earth orbit.  They’re worried that more and more junk flying around up there will make it difficult for humanity to reliably operate satellites or manned vehicles.

Trash in orbit isn’t a new issue - it came up a couple years ago as a result of the Chinese test to shoot down a satellite, though the debris concern was somewhat overshadowed by totally legitimate fears of the militarization of space.

What scientists and spaceflight supporters hope to avoid is what’s called the Kessler Syndrome - a chain reaction set off by debris collisions that cause more debris and, therefore, more collisions.  The result of this scenario is such a high risk of collision in orbit that it renders impossible many or all of the space-based activities that we currently take for granted.

NASA’s on the case, though, with their Orbital Debris Program Office at the Johnson Space Center.  The coolest thing on their site is a link to the facility where orbital debris collisions are modeled - the Hypervelocity Impact Technology Facility.  They use high-speed cameras, light gas guns and computer simulations (with video!) to explore how collisions at orbital velocity (kilometers per second) will effect various shielding materials.

The European Space Agency is also taking a serious look at the space debris problem.  Watch a video showing the build-up of orbital debris over the last 50 years on their Space Debris Spotlight page and check out their own work on hypervelocity impacts on the space debris section of their website.

This has to be one of the best, if not most humorous, perspectives on the progress of technology in our lifetimes that I have seen. Louis CK on Conan Obrien.

We are programmed to be interrupted.

Wired has a great interview with an author named Maggie Jackson who has written a book about the neurobiological basis of attention and how it is affected by all the “lovely distractions” modern society provides.   Distracted: The Erosion of Attention and the Coming Dark Age describes three types of attention - orientation, a general sense of awareness, and executive.  Her concern is that our modern technological culture is constantly distracting us - and that we like it.  Scientific American just ran an article about a study with similar findings:

Results suggested that thinking fast made participants feel more elated, creative and, to a lesser degree, energetic and powerful.

In the Wired interview, Maggie Jackson explains:

We are programmed to be interrupted. We get an adrenaline jolt when orienting to new stimuli: Our body actually rewards us for paying attention to the new. So in this very fast-paced world, it’s easy and tempting to always react to the new thing.

As great as all this stimulation make us feel, though, it complements a loss of the more deeply engaged sort of attention we need for the strategic planning and accomplishment of larger goals.  Unfortunately, she paints a dire picture - not only do we have a natural inclination to be distracted (on top of ample opportunities), but we are encouraged to by social pressures:

In our country, stillness and reflection are not especially valued in the workplace. The image of success is the frenetic multitasker who doesn’t have time and is constantly interrupted. By striving towards this model of inattention, we’re doing ourselves a tremendous injustice.

The negative side-effects of this increased level of distraction manifest at individual and societal levels:

This degree of interruption is correlated with stress and frustration and lowered creativity. That makes sense. When you’re scattered and diffuse, you’re less creative. When your times of reflection are always punctured, it’s hard to go deeply into problem-solving, into relating, into thinking.

Dark ages are times of forgetting, when the advancements of the past are underutilized. If we forget how to use our powers of deep focus, we’ll depend more on black-and-white thinking, on surface ideas, on surface relationships. That breeds a tremendous potential for tyranny and misunderstanding. The possibility of an attention-deficient future society is very sobering.

An ‘attention-deficient’ society obsessed with staying on top of things is a society that is stuck in the orientation phase of attention, makes snap judgments and is subject to the whims of cognitive shortcuts.

The distinction Jackson is illustrating through her research was summed up pretty well in one of Kevin Kelly’s blog posts on those who have ‘dropped out.’  He quotes Donald Knuth, who no longer uses email, saying, “Rather than trying to stay on top of things, I am trying to get to the bottom of things.”

Update: Interesting criticism/follow-up discussion on Mind Hacks.

Note to Leibnitz and Newton… Archimedes beat you both.

Monday, January 19th, 02009

 To those of you following the Leibnitz - Newton “who discovered calculus kerfuffle“, a  newly re-discovered Archimedes text has revealed that he actually had documented several calculus principles over 2,200 years ago.  More over at Science News on the riveting story of how x-ray fluorescence imaging revealed the underlying text after a 13th century Monk scraped the pages clean in order jot down some prayer...

 


“Archimedes computed the area of the curved figure (left) by enclosing it in a bigger one with straight edges (right). He then examined random slices to compute the volume—using the concept of actual infinity. “
