Have you ever had the experience of noticing a certain pattern in a wild variety of contexts, a pattern that occurs so consistently that you feel it simply has to mean something … but you have no idea what? I say “in a wild variety of contexts” to rule out cases of patterns that occur within the same context, even though, at the time, you may have no idea of the cause.

Interstellar is a not just a science-fiction (SF) movie, it is a science-fiction movie, i.e., it does not cut any corners in terms of depicting the actual consequences of near-light travel, e.g., time dilation, black-hole physics, etc. (In that respect, Interstellar is a cinematic fraternal twin to Dan Si
I write this the morning (13 February) after Diane and I had a wonderful, long, and calorie-filled dinner with two very senior people associated with the Keck Telescopes and the other telescopes atop Mauna Kea on the Big Island of Hawaii. It was a memorable evening that still resonates with me. One reason that conversation sticks with me -- aside from having discussed dark energy, blue-sky (black-sky?) projects for exploring the Proxima Centauri system, gamma-ray bursts, gravity waves, black holes, etc., etc. – is that one of the subjects we touched on banged down pretty hard on one of my hot-button issues: scientific illiteracy in general in the US and the western world, and the need for informed, literate teaching of science to non-scientists. I mean science per se, not just astrono
