Creativity

Driven to distraction by technology

Fri, 22 Jul 2005 10:56:03 -0400

The typical office worker is interrupted every three minutes by a phone call, e-mail, instant message or other distraction. The problem is that it takes about eight uninterrupted minutes for our brains to get into a really creative state.

The result, says Carl Honore, journalist and author of "In Praise of Slowness," is a situation where the digital communications that were supposed to make working lives run more smoothly are actually preventing people from getting critical tasks accomplished.

Honore, who cited the estimate of an interruption every three minutes, acknowledges that he would not part with his laptop or phone. But he adds that "it's possible to get too much of a good thing. As a society, that's where we are at the moment."

The Dream of a Lifetime

Mon, 11 Jul 2005 11:07:33 -0400

You've likely heard stories about the birth of the PC: of Xerox PARC as the Mecca of computing; of its creation of the Alto, Ethernet, and the laser printer; of the Homebrew Computer Club, the MITS Altair, Bill Gates and the theft of his Micro-soft Basic; of Steve Jobs and Stephen Wozniak, the founding of Apple, and the Jobs visit to PARC that inspired the Macintosh.

But what you may not know about is the really early history. The stories of Doug Engelbart and John McCarthy, of the Augmentation Research Center, and of the early days of the Stanford University AI Lab (SAIL) are not well known. Yes, you may have heard that Engelbart invented the mouse, and that SAIL and Stanford led to companies like Sun and Cisco. But there are better stories, great and old ones from the early days of computing, about the events that led to personal computing as we know it.

In his wonderful new book, What the Dormouse Said..., John Markoff tells these stories.

Dream teams thrive on mix of old and new blood

Wed, 04 May 2005 10:26:29 -0400

When the Boston Red Sox won their first World Series title since 1918 last year, the team had some new blood, including key players Curt Schilling, Orlando Cabrera and Doug Mientkiewicz, to mix with the old and help the team achieve the pinnacle of baseball success.

In a paper to be published April 29 in the journal Science, Northwestern University researchers turned to a different type of team -- creative teams in the arts and sciences -- to determine a team's recipe for success. They discovered that the composition of a great team is the same whether you are working on Broadway or in economics.

The researchers studied data on Broadway musicals since 1877 as well as thousands of journal publications in four fields of science and found that successful teams had a diverse membership -- not of race and gender but of old blood and new. New team members clearly added creative spark and critical links to the experience of the entire industry. Unsuccessful teams were isolated from each other whereas the members of successful teams were interconnected, much like the Kevin Bacon game, across a giant cluster of artists or scientists.

Building A Better Brain

Thu, 24 Mar 2005 13:49:55 -0500

Forget about smartphones. Two of the big brains behind those essential toys say they will build the basis of smart--really smart, like humans--machines, everywhere.

Jeff Hawkins and Donna Dubinsky, creators of the Palm and Handspring personal digital assistants and the Treo smartphone, have formed a software company built around a powerful and unorthodox vision of how the human brain works. In its early stages, they hope to create predictive machines useful for things like weather forecasting and oil exploration. Further out--much further, says Hawkins--they plan to lay the basis for cosmologically attuned robots that conceive and reflect on the universe itself.

Okay, it is a big idea. And so far the Menlo Park, Calif.-based company, called Numenta, has built what the creators say is a set of tools for creating pattern-recognition software capable of "learning" shapes and events, with a goal of foreseeing what the pattern will next create. Yet these tools draw on decades of work that Hawkins has done on how the brain works. If it pans out--and there is an attractive logic to much of his thinking--Numenta may certainly oversee the creation of embedded software that adapts and improves its own performance.

"Aristotle" (The Knowledge Web)

Mon, 31 May 2004 00:20:15 -0400

(DANNY HILLIS:) I have always envied Alexander the Great, because he had Aristotle as a personal tutor. In those days, Aristotle knew pretty much everything there was to know. Even better, Aristotle understood the mind of Alexander. He understood which topics interested Alexander, what Alexander knew and did not know, and what kinds of explanations Alexander preferred. Aristotle had been a student of Plato, and he was himself a great teacher. We know from his writings that he was full of examples, explanations, arguments, and stories. Through Aristotle, Alexander had the knowledge of the world at his command.

Of course no one today knows all that is known, in the sense that Aristotle did. Now there is far too much knowledge for that to be possible. The scientific revolution, and the technological revolution that followed it, led to a self-reinforcing explosion of knowledge. The explosion continues. Today not even the most highly trained scientist, the most scholarly historian, or the most competent engineer can hope to have more than a general overview of what is known. Only specialists understand most of the new discoveries in science, and even the specialists have trouble keeping up.

This problem isn't new. In 1945, Vannevar Bush wrote an essay for Atlantic Monthly about out the problem of too much knowledge. He wrote,

Neural Activity When People Solve Verbal Problems with Insight

Tue, 13 Apr 2004 18:49:15 -0400

People sometimes solve problems with a unique process called insight, accompanied by an “Aha!” experience. It has long been unclear whether different cognitive and neural processes lead to insight versus noninsight solutions, or if solutions differ only in subsequent subjective feeling. Recent behavioral studies indicate distinct patterns of performance and suggest differential hemispheric involvement for insight and noninsight solutions. Subjects solved verbal problems, and after each correct solution indicated whether they solved with or without insight. We observed two objective neural correlates of insight. Functional magnetic resonance imaging (Experiment 1) revealed increased activity in the right hemisphere anterior superior temporal gyrus for insight relative to noninsight solutions. The same region was active during initial solving efforts. Scalp electroencephalogram recordings (Experiment 2) revealed a sudden burst of high-frequency (gamma-band) neural activity in the same area beginning 0.3 s prior to insight solutions. This right anterior temporal area is associated with making connections across distantly related information during comprehension. Although all problem solving relies on a largely shared cortical network, the sudden flash of insight occurs when solvers engage distinct neural and cognitive processes that allow them to see connections that previously eluded them.

Study confirms sleep essential for creativity

Mon, 08 Mar 2004 10:37:36 -0500

Everybody feels refreshed following a good night's sleep. But can you wake up smarter? More artistic perhaps?

German scientists say they have demonstrated for the first time that our sleeping brains continue working on problems that baffle us during the day, and the right answer may come more easily after eight hours of rest.

The German study is considered to be the first hard evidence supporting the common sense notion that creativity and problem solving appear to be directly linked to adequate sleep, scientists say. Other researchers who did not contribute to the experiment say it provides a valuable reminder for overtired workers and students that sleep is often the best medicine.

Stephen Thaler's Creativity Machine

Tue, 13 Apr 2004 13:43:37 -0400

Technically, Stephen Thaler has written more music than any composer in the world. He also invented the Oral-B CrossAction toothbrush and devices that search the Internet for messages from terrorists. He has discovered substances harder than diamonds, coined 1.5 million new English words, and trained robotic cockroaches. Technically.

Thaler, the president and chief executive of Imagination Engines Inc. in Maryland Heights, Mo., gets credit for all those things, but he's really just ``the man behind the curtain,'' he said. The real inventor is a computer program called a Creativity Machine.

What Thaler has created is essentially ``Thomas Edison in a box,'' said Rusty Miller, a government contractor at General Dynamics and one of Thaler's chief cheerleaders.

``His first patent was for a Device for the Autonomous Generation of Useful Information,'' the official name of the Creativity Machine, Miller said. ``His second patent was for the Self-Training Neural Network Object. Patent Number Two was invented by Patent Number One. Think about that. Patent Number Two was invented by Patent Number One!''

Supporters say the technology is the best simulation of what goes on in human brains, and the first truly thinking machine.

Others say it is something far more sinister -- the beginning of ``Terminator'' technology, in which self-aware machines could take over the world.

Sleep boosts lateral thinking

Thu, 22 Jan 2004 21:49:54 -0500

"Sleep on it" is standard advice to anyone agonizing over a tricky puzzle. A study of mathematical problem-solving has now shown that a good night's rest really does give you a fresh perspective.

The discovery lends credence to the popular maxim that sleep stimulates lateral thinking, says Jan Born of the University of Lübeck, Germany, who led the project.

"Every act of creation is an act of hope."

Sun, 11 Jan 2004 00:18:09 -0500

So we reach for art and music, though we know it will be flawed,
Yet in striving to do better, we are reaching out to God.
We are reaching for perfection, and it's not beyond our scope;
Every act of creation is an act of hope.
- Catherine Faber, Acts of Creation

"...the most fruitful developments frequently take place at those points where two different lines of thought meet."

Fri, 09 Jan 2004 13:12:32 -0500

It is probably true quite generally that in the history of human thinking the most fruitful developments frequently take place at those points where two different lines of thought meet. These lines may have their roots in quite different parts of human nature, in different times or different cultural environments or different religious traditions: hence if they actually meet, that is, if they are at least so much related to each other that a real interaction can take place, then one may hope that new and interesting developments may follow.
