The trail of ants across the sidewalk is still there.

The trail of ants across the sidewalk is still there but getting a little thin. I still can't see what the attraction is (or was).
There was an unusually large number of airplanes passed over during my walk. Four planes, two going East and two going West. The significance? Who knows?
The author of the book I'm reading, "The Trouble With Physics" is winding up with a discussion of the sociology of physics. How focusing on one problem (String Theory) detracts from progress in other, equally promising avenues of investigation. But what struck me is the difference in educational emphasis has changed from open investigations to only those supported by from. In other words, if it don't make a profit, it ain't worth the time. Had those restrictions been in place in the 30's we would still believe the Earth is the center of the universe. What struck me was the coincidence of the change in the direction of physics research with the rise of Reaganism, where greed trumps all. But I'm not sure I can fully develop the thesis in a reasonable space. But it feels right in my gut.
Deep thoughts show us all that we're all on this flight together.
