Just came across this cool artifact: “Viking Lander Biological Instrument, Life on Mars” matchbox. (“The most complex instrument ever flown “) From a party in Pasadena for first Mars landing in 1976. Handed down to me by the late, great Shirley Arden (Carl Sagan’s long time executive assistant). 🧪
Picture of a gold matchbox with black design of a little Martian bug holding a spear and sword, with the lettering: VLBI, the most complex instrument ever flown.Other side of the matchbook .The little Martian dude with “TRW” and “Life on Mars?”

Bears repeating today…
If you really want a Star Trek future, it’s not just going to space in cool machines.
It’s building a society w respect for all life, sentient & otherwise, applying science wisely, & pursuing principles of justice, fairness & reason.
Let’s build that and ride it to the stars.

Huh. Here’s a piece about using AI for writing that is actually interesting and provocative. Neither fawning nor reflexively fearful. www.theguardian.com/commentisfre...
The task of writing in the age of AI is the same as it has always been: to see through the various manias and cults, to unpack the mechanisms that make the world turn, to ring the bells that still can ring.

Common sense might also help. “Render unto man the things which are man’s and unto the computer the things which are the computer’s,” Norbert Wiener, the father of cybernetics, wrote. “This would seem the intelligent policy to adopt when we employ men and computers together in common undertakings. It is a policy as far removed from that of the gadget worshiper as it is from the man who sees only blasphemy and degradation of man in the use of any mechanical adjuvants whatever to thoughts.”

profile tracing lowest slope values around crater rim (red). Profile starts at the 12 o’clock position and runs around the
crater clock-wise. Note the rim is highest on the southern side. The blue profile runs down the NT (Fig. 2) through
the crater center and across the southern rim, near the peak of the rim traverse profile (red).
