It has been suggested that I sound “too preachy.” Yeah, that should have been expected. Let me introduce myself a little more to those of my neighbors who, so far, have only smiled and waved.

As you probably have noticed, there’s nothing like a conservative preacher, any teacher, or a flaming liberal, to tell you just how things ought to be.

First, I was actually the closest thing to a conservative preacher in my young manhood. I was raised in a fundamentalist, evangelical Christian faith that believed in the ordination of all lay ministers. During that time, I led adult Bible study groups every week for years. For the record, the brotherhood and I eventually saw fit to part ways.

Second, I have also regularly taught children and adults. I spent almost two decades in computer work for Amoco Oil Company, where I designed and led many technical classes. Next, I spent a decade as an herbalist – telling people how to live. I was also a substitute teacher for several years and am married to a career public school teacher.

While I was with Amoco, they gave me a series of career-development psychology tests. In one of them, my top two archetype identifications were found to be “Evangelist” and “Warrior.” That was tough news for someone with social anxieties.

The counselor had a hard time putting his finger on my potential. He mumbled his way through the obvious, but I knew he was thinking: missionary to the heathens, tilting at windmills, and questing hero. In the end, Amoco buried me deep in the corners of several computer rooms. I managed to make trouble anyway.

And finally, in case you haven’t noticed, I’ve become that odd duck in the middle of rural Iowa, a flaming liberal. Find me a tree and I’ll hug it. Fear not, my good neighbors. I am a gentle soul and, as my wife says, “the nicest man I’ve ever met.” I’ll put it out there and you can buy it or not. I quit putting my foot in actual doors a long time ago. Love, DavidS

Do you ever get involved in something so deeply that nothing else seems to matter and you lose track of time?

Yes, frequently.

Throughout life, I have been prone to be introspective, voraciously curious, and a creative problem solver. I enjoy “disappearing into the problem.” I am more of a craftsman then an artist. Nonetheless, my explorations and projects easily consume my full attention. By the early 1990s I had discovered and read Csikszentmihalyi’s book on “Flow” and quickly recognized the altered state of mind that I cherished. Armed with a theoretical foundation, I have been able to more deliberately produce flow experiences.

I read and study more slowly than most. I often experience flow while working to understand, organize, and incorporate new knowledge into my belief system. This can be more difficult because I have a historically poor retention for details and I take the time to acknowledge and consider levels of ambiguity. I usually experience the deep-involvement of flow during this type of independent self-study; classroom instruction generally requires the opposite: waiting, diffusion, and disassociation.

Technical work has frequently produced flow experiences. These include designing electronic circuits, programming, analyzing systems, troubleshooting, computer programming, database design, and many others. In one programming project, I arranged with my supervisor to work for three weeks in an unmarked locked room outside of my departmental area, with no telephone or meetings. I brought a bag lunch and was usually able to stay in focus while walking to the restroom head-down and refusing to interact with anyone. I consider the result to be some of my best work. I tend to advance into a new technology or field of interest every two years or so. Early on, in an attempt to stay focused, I specifically excluded brain surgery from my potential career path.

I often find myself tackling new projects that challenge my existing knowledge and skills. At work, I have advanced and receive promotions, including directing the work of and teaching technical classes to engineers, by mastering new technologies almost exclusively through self-study. In one case, I was given full responsibility for designing and installing a new generation of plant-wide process data acquisition system at Amoco’s largest refinery. I frequently lobbied for and successfully introduced innovations.

I have replacing a diesel engine in my Oldsmobile station wagon with a computer-controlled later-model gasoline engine. I have undertaken home additions, outbuildings, and complex remodeling projects. At one point, I set and achieved the goal of becoming “a nationally recognized natural health educator.”

These are just a few examples. Essentially, I thrive on, and continually seek-out flow experiences. My current quest is to move beyond mastering technologies to building a better intellectual framework for understanding complex systems, especially the many strands and stages of human development. I find flow more and more often while writing to explain and interpret specialist-level material for interested laymen.

Addendum: I was recently delighted to discover a fictional model for my own life experience while impulsively reading a 1950s middle-school novel set in the period of the American Revolution.

Lecture 5 – Googling the Brain on a Chip (Kwabena Boahen)

Kwabena Boahen is using the human brain as the blueprint for designing radically more powerful and energy-efficient computers.

In this short demo, Boahen describes how his Brains in Silicon lab at Stanford University has created computer chips with "synapses" and "neurons" — and how these chips might revolutionize computing.

Lecture 3 – Brain-Computer Interfaces

Krishna Shenoy is creating "brain-computer interfaces" that will enable paralyzed patients to control prosthetic arms and computer cursors.

In this short talk, Shenoy describes how his team of Stanford researchers has built a system that achieves typing at 15 words-per-minute, just by "thinking about it".
