Leon Rosenfeld, a coworker of Neils Bohr, commented that a model is not “sufficiently defined…
Aug 24, 2015 “Really and Truly” Thinking is done with nerves and words. Nerves don’t transmit information: the discharge of one nerve stimulates another to discharge, discharges of many nerves are linked and sorted into patterns of activation, and the patterns are rendered into words and arranged into narratives,…
Aug 18, 2015 An apparently empty patchwork of darkness strung across this field of stars is actually full—of dust and gas and Other Things. The dust and gas doesn’t show up because there’s not sufficient light that we can see for it to reflect, and it isn’t hot enough to…
Aug 17, 2015 Plasma: The New Kid on the Block Institutional astronomy’s blind spot in intellectual vision is in the beginning. Although astronomers acknowledge that everything they see is plasma, they fail (or refuse) to see the empirically discovered electromagnetic properties of plasma. Habits of thought brand plasma as…
Aug 12, 2015 These two galaxies appear to be elbowing each other with their spiral arms. The consensus interpretation is that they’re colliding and generating shock waves that initiate gravitational collapse of gas clouds. The collapsing clouds become stars, many of which are extremely massive. These quickly run through their…
Aug 10, 2015 New sights for old eyes We live in a constellation Of patches and of pitches…, Thinkers without final thoughts In an always incipient cosmos…. –Wallace Stevens, July Mountain The Big Bang appears to be the final thought of astronomical scientific endeavor.

Jul 29, 2015 Another epistemological tour de force. Probable, Possible, my black hen, She lays eggs in the Relative When. She doesn’t lay eggs in the Positive Now Because she’s unable to postulate how. — The Space Child’s Mother Goose By Frederick Winsor People don’t pay much attention to “how”…
July 20, 2015 This image of Stephan’s Quintet is befogged with the same obsolete commentary as previous images: the foreground galaxy, collisions, shock waves, and heat. Editor’s note: Please enjoy this Picture of the Day from July 20, 2009. The foreground galaxy (bottom left) is believed to be in…
Jul 14, 2015 “Our choicest plans have fallen through, our airiest castles tumbled over, because of lines we neatly drew and later neatly stumbled over.” — Piet Hein GROOKS I was checking out the dynamics describing the orbit of SOHO, the sun-watching satellite oscillating around a mathematical point in empty…
