The Wall and a Memory


When Trump talks about the Wall, it reminds me of a radio show in which a physicist and the famed 1934 MVP curve ball pitcher, Dizzy Dean, were being interviewed.

The physicist -- who had either failed to examine a baseball and notice that it had raised threads or was just a rather bad scientist -- argued, using a smooth cue ball as his model, that curve balls were not real, but an illusion. That without imparting new forces on a ball in flight, it could not be made to curve. (The actual physics is more complicated, but a baseball can curve because the rotational forces of the ball have discretely different impacts as the ball slows; the friction of the raised threads in the atmosphere creates changed forces on the flight of the ball as it slows. An easy way to think about it is that once the ball's velocity drops below a threshold level, the threads "catch" the air and steer the ball in a new direction.)

But no one on that radio show was giving any lectures about irregular surfaces, rotational forces, and threshold levels. Instead, Dizzy Dean proposed a simple experiment:

"Put the professor behind a tree and I'll bean 'em."

Build a mile long stretch of wall somewhere and hold a contest to see if people can get under or over it with equipment they can carry there for, say, 10 miles. Once you find a model that cannot be transgressed, you can begin to do the environmental impact, societal, legal (eminent domain), respectful (e.g., avoid Navaho sacred sites), and other (e,g., discussion of international relations, xenophobia, and immigration broadly) tasks that must be done before you turn it into a $20-50B project (as $5.7B is according to all experts, a lie, intending massive overruns).

Note that this is the first and last time I will ever compare Trump to a physicist. H's not even as smart as Dizzy Dean -- who, it may be noted, dropped out of school in the 3rd grade, and was famous for saying on air: "The Good Lord was good to me. He gave me a strong right arm, a good body, and a weak mind."
