Here's me talking about #science and #Shakespeare in Kansas City last Thursday, with Eric Ward, VP for Programs and Education at the Linda Hall Library of Science, Engineering & Technology:

Robert Redford was in a whole whack of good films, but my two favourites are The Sting (1973) and All the President's Men (1976), both of which hold up to repeated viewings a half-century later.

Got up early for this one. :) The waning crescent moon -- and Venus -- and their reflections -- at Geier Lake, NS, June 2025: ( #photography #nightphotography #novascotia )

The photo shows the moon and Venus, and their reflections in a calm lake. It is at least an hour before sunrise, and the sky is a very deep blue.

I’m enjoying the circular wave patterns that the helicopter makes. 🔘 🙂

The 2nd law of thermodynamics famously points to death and decay--but, could there be another, overlooked law responsible for *increasing* order? Robert Hazen & @miquai.bsky.social make the argument in their new book, "Time's Second Arrow." I spoke with them for @nautil.us: nautil.us/time-brings-...

It was a treat to see some of the items in the rare book collection at the Linda Hall Library in KC last month. Here's Bruce showing me a first edition of Galileo's Siderius Nuncius; also, here's Edward Topsell's "The History of Four-footed Beasts" (1607). #books #science #histsci

I always enjoy these Lowell-involved newspaper headlines — e.g. this one from 1911, seen here in A Universe of Earths by Danielson and Graney:

A 1911 page from the New York Times with the headline, “Martians build two immense canals in two years.”

You've all seen the April 2 "whole Earth at night" photo; just for fun, I've added the names of some of the cities whose lights are seen in the pic. (Obv there are some others one could add, but I didn't want to get too carried away.) #NASA #Artemis #wholeEarth

Here we see the original NASA "whole Earth" image at lower-left; then at upper right we see a close up of North Africa and southern Europe, with a number of cities identified by text and arrows.

Two mildly irksome items: when a journalist pronounces it “Nassau” rather than NASA; and when they say “dark side” when they mean “far side.”
