Who? What? When? Why? Where? How? Those were the questions I was taught to ask on every doubt. I had the good luck to attend the only college with a basketball court size map of the 48 states of USA. I haven’t been back for years but I understand that the space has been re-purposed. Lacking the balcony view of the curve of earth (Who needs that now with Google Earth). And lights that light up (if they were working) of the selected cities on the switch boxes. At least the Babson Globe has been restored.
I was addicted to maps long before that and still. The INTERNET can provide.
Now (when it may be vital to establish jurisdiction) I discover that my (unnamed) INTERNET provider not only mis-locates me but makes my locus a place which differs from the center determined by measurement.
Potwin, KS may be a rounding error.
Eureka, KS may be a closer center.

While there were no U.S. mine fatalities in 2009, this year’s toll is already too large. The various states agencies and the federal government provide inspections and enforcement of regulations. But death and injury still continue to occur in mines. May I suggest a regulation that requires the CEO of the mining company to personally inspect each mine at least once per quarter and the next tier of management at least once per month. By inspection, I am not talking about a photo-op, above-ground visit. What I had in mind was a trip to the mine face, up-close and personal. It is possible that this would bring additional focus on the safety and conditions in the mine.

I do not claim any understanding of Nelder-Mead or anything like it, also called a downhill method of finding a minimum for a system of equations, which, if you keep up with these things, may be old news. But consider the possibility of the inverse, nearing the summit realizing that whatever your strategy and method, the climb has led you up the wrong peak. Or more to the point, in the valley, you cannot realize or see that the adjacent (or some very distant) valley is lower but not chosen because the initial solution set off in the wrong direction. The desired goal is now distant. Maybe in Step n, there could be a global check for other minima. Or maybe this accomplishes that trick.

While looking for information on “splines”, I stumbled over an interesting article in the Community Resources section of the Resources Tab for the Geology Department of Portland State University. The pdf file is a Self-guided tour of Portland, Oregon’s geology. This field trip provides an introduction to the geology of the Portland, Oregon, area. Five field trip stops, all accessible by public transportation and walks of easy to moderate difficulty, provide opportunities to see outcrops of Columbia River Basalt, Troutdale Formation, Boring volcanic field flow and vents, Portland Hills Silt, and a small landslide. I have never had a chance to visit the Northwest but might like to some day. This paper is an exciting chance to visit the neighborhood of Mt. St. Helens vicariously. And a way to spend a day or two out and about in the Portland area.

Also exciting is the description of the floods in the Portland area on 20-15 thousand years ago. Water levels 150m higher than current sea level! What short memories humans have. Maybe the geologists should buy the climatologists a cup of coffee and fill them in on life on earth.

Comments received on my earlier blog relative to global warming indicate that some politcos took offense.  While I think they should be wearing stripes ala prison garb, the stripes I had in mind at the time were those worn by family Mephitis mephitis.

A friend at work loaned me the book that I am reading now.  A Geologic Trip Across Tennessee by Interstate 40 by Harry L. Moore.  This is part of the Outdoor Tennessee Series.    This book appears to still be available and if you are a travel, outdoor, hiking, geology, or history buff in the southeast, you might enjoy this book.  I happen to like geology and hiking.  While I am not fond of driving, I like to know the trerrain I am driving through.  If you are travelling through Tennessee and looking out the window, this book will give you a good idea of things to watch for in the landscape and as you look at the ground underneath you.
