4 October 1825: back in Lyme Regis after a tour of SW England, geologist Roderick Murchison noted in his journal, 'Accompanied by Mary Anning rode to Dowlands & dismounted there'. They spent the day exploring the geology of the landslipped cliffs and foreshore to the west of Lyme.

It's October 4th -- the Sputnik satellite was flung into orbit 69 years ago today, beginning the age of space exploration. I dug into the Russian archives and got some documents on its creation. Check it out if you're interested.....

Thomas Young, who was the first person to explain & demonstrate the properties of light in terms of wave motion also was first to explain that supernumerary arcs are a consequence of waves interference.

When my father was faculty at Cornell he was stopped by the police chief in the street & asked who he was & where he was going. When he balked at the fact that no one but him, an Arab man, was being asked, the chief said “I’m just protecting students” Same guy failed to investigate 7 rapists.

I've been thinking about life after the ecological collapse. Many of the species we love will be extinct. But probably not liverworts. They sound kinda gross, like liver with warts. But I've come to love them. Let me tell you why.

For #spacetober_challenge day 2: galaxy - astronomer Vera Rubin (neé Cooper, ‘28-‘16) & her discovery that angular motion of galaxies deviates from predictions, 1st evidence for dark matter, now known as 5x as common as matter & the stuff which dictates dynamics of galaxies & 🧪🐡👩🏼‍🔬🔭 #histsci
My linocut portrait of astronomer Vera Rubin with short hair, glasses and resting her face in her hand in burgundy on a background of outer space with stars and galaxies in black with blue and pink splotches to mimic how dust bends light in space. At the base of the print is a large spiral galaxy with a plot of orbital velocity versus distance going out from its centre (so the distance axis is indeed distance from centre). There are two lines labelled “observed” which goes up from the origin and then is a pretty flat wavy line all the way across. This line marks the bottom of Rubin. Below it is a wide empty gap of visible white paper down to the second line labelled “predicted”. The Predicted line goes up from the origin to a peak where it diverges from the observed and falls smoothly back down in a gentle curve.

In 2011 I wrote a review of the new printing of Julian Huxley's Evolution: The Modern Synthesis. I included this musing which still seems relevant.
I have focused this review on some aspects of Huxley's portrayal of evolution that I
find particularly powerful for thinking about evolution and that are perhaps
underappreciated. It goes without saying that various aspects of the book have not
withstood the test of time as well as others. In particular, Huxley's discussion of
evolutionary progress, especially its relation to the future evolution of humans seems
to me to show that Huxley was fundamentally a man of his time (I find it irresistible
to mention that Huxley expressed hope for work on telepathy and extra-sensory
perception). Be that as it may, some of his arguments may offer insight, as well as
serve as a cautionary tales, to those thinking about notions of transhumanism, and
those such as Ray Kurzweil and Eliezer Yudkowsky who suggest that "the singularity
is near." The notion of “singularity,” as used by these thinkers, refers to an
“intelligence explosion” we are about to experience as result of successive
generations of intelligent machines, each able to design a next generation of even
more intelligent machines. While arguably all too optimistic about progress, Huxley concluded his book by noting that our optimism about the future progress of human
evolution "may well be tempered by reflection on the difficulties to be overcome."

In case anyone needs to hear it, making references to Simon of Trent as if the legends about him have any basis in reality puts a big red flag on you that says "antisemite." If you don't understand why that is, I recommend reading a damned history book. Like this one maybe:
