M. King Hubbert

In terms of human history, the episode of fossil fuels is a very brief epoch.

                                                                       M. King Hubbert

Marion King Hubbert was a geologist whose life spanned from the year the Wright Brothers first flew at Kitty Hawk to the collapse of the Soviet Union. A native Texan, Hubbert received his BS, MS, and PhD from the University of Chicago, and worked for Shell Oil from 1943 until 1964, was a research geophysicist for the US Geological Survey, and taught at Columbia University, Stanford, and UC Berkeley.

In 1956, Hubbert ssuggested that production in a geographic area -- ranging from a single oil field to the planet -- will follow a bell curve, and predicted that production in the United States would peak around 1970, which proved to be the case. Later he predicted a global peak around 1995, a little earlier than what happend, but close. The so-called Hubbert Curve is based on historical trends rather than estimates of reserves and consumption. Subsequent researchers have found similar curves in fisheries.

Hubbert also showed that rock in the Earth's crust is plastic -- it changes shape under pressure -- and formulated the correct statement for Darcy's Law, which describes the relationship between the rate flow of a fluid through a permeable medium and permeability, area, pressure drop, viscosity, and length.

He was a Technocrat, a founder of a Depression-era movement that advocated that scientists and engineers, not politicians, coordinate the economy. Hubbert believed in an economy in which goods and services were priced according to the energy consumed in their production.

Drawing Method



I'm trying, with intermittent success, to make a concentrated effort with my drawing. I'm working on a series of forty or so portraits of people who have been sources for the ideas that make up my worldview, the "Faces of Wisdom Series" ten or so of which I've already published.

Above: three scans to demonstrate my method, a photograph of geologist M. King Hubbert, a pencil copy of the photo, and the beginning lines of the ink rendering. Besides the chance to personify ideas I wish were more common in society, what I get from this series is practice at catching proportions, a skill I need to work on, and practice making clean and meaningful lines with a fairly shaky hand. And, I'm learning a lot about the relief of the human face by making the lines I shade with wrap around the forms.

The real surprise is that drawing from photos is harder for me than drawing from life. I never make pencil under-drawings when I draw from life. I've used snapshots of subjects for my newspaper profiles, to spare my subjects the tiresome chore of sitting still for half an hour or more, but it takes a lot longer for me to get things right. Hubbert's head, for instance, started out about the length of his hair longer, and it still looks a little tall.
