No ... it's can't be!  <sarcasm>There is no way that I can believe for a second that the earth is at all warmed by the sun!  Although I haven't yet seen Al Gore's movie, I've heard it's all full of hard evidence that Global Warming is caused by us humans.  How could it be otherwise?</sarcasm>

Uh ... wow.  This scientist is probably going to come under a lot of attack from folks about this ... but he's saying that maybe ... just maybe ... there are bigger forces at work than us humans.  Imagine that.

A few years back I attended a conference at Stanford and watched a presentation by some of the folks at Numenta.  It was very impressive, and discussed the architecture of the hierarchical temporal memory (HTM) system.  There were several other presenters that discussed the learning of how the brain stores patterns, and does pattern matching.

What I really like is the thinking that dovetails with other articles and books that I have read, and how the brain - from childhood - constructs a model of the universe, and we the interact with the world using that model as a base reference for predictions and "next moves."

Numenta has now released their Numenta Research Release.  It is now at the stages for researchers to begin to look at and experiment.  Of course it's not just download and run ... in Jeff's own words:
We have found that it takes some developers months to get familiar with the concepts, and maybe a year to get commercially useful results. It also is possible that your first attempts at using HTM will be valuable for learning, but not valuable for commercial applications. The learning curve is similar to the learning curve for writing computer software. It takes anywhere from several months to a year to become proficient in writing computer software; HTMs have similar complexity.

The best part that I like about these theories and examples of possible brain models, is that we can learn a lot about ourselves from these.  How we work.  If the brain creates a model, and that is then used to interact with the world, then that model begins to define the limits of our interactions.  The funny part, is that most people fail to distinguish that it is simply a model ... not the "truth", and not fixed.  And so quite often their own model of the universe constrains their behaviors and actions, limiting what they can do.  I took a number of courses from Landmark Education that focus on this specific area ... learning to distinguish that model, and to then learn to evolve and update that model.  It is amazing experience each time I distinguish something new about how flawed my model of the universe is.

Even with the understandable doubts expressed by the author of this article ... I am impressed with Jeff and his work, and believe that he is on the right track.
