An article I saw today details a debate (in Heisenberg’s old stomping grounds of Helogland) in which Carlo Rovelli and Chris Fuchs argue about how best to interpret Heisenberg’s intuition.

Claude the alligator’s cause of death revealed: β€˜There was nothing we could have done’ As Bay Area residents mourned the death of Claude the albino alligator this week, the California Academy of Sciences received the results of a necropsy.

Claude the albino alligator, the unofficial but very real mascot of the California Academy of Sciences, has died at 30, apparently of liver cancer. I’m kind of broken up about it.

In all seriousness, may his memory be a blessing.

Mivart seemed to believe that Darwinβ€˜s theory entailed that if a suite of traits would be advantageous to an organism, they would necessarily evolve. This was a misunderstanding of Darwinβ€˜s ideas. Darwin pointed out that many advantageous traits will never appear in a lineage.

If long necks favor giraffes on the African savannah, M asked, where are the *other* long-necked ungulates? Why are there not vast herds of giraffopottamuses sweeping across the veldt?

Expression was also important in the history of the book, being an early instance of a book that included photographs, notwithstanding publisher John Murray’s worry that including photos would β€œpoke a hole in the profits.”

Darwin was a pioneer in experimental psychology, showing photos of human faces that had been galvanically stimulated to represent different emotions to visitors to Down House in an effort to determine which emotions could be reliably identified. 3/4

Darwin had earlier made detailed observations of the emotional displays of his β€œlittle animalcule of a son,” William Erasmus, which he used in Expression.

D’s wife Emma worried that if she were β€œout of temper,” he would just be β€œforming theories about me.”

Charles Darwin's The Expression of the Emotions launched OTD in 1872.

Just as our bodily form has evolved from our animal ancestors, so too have our minds, including "the habit of expressing our feelings [or, in his title, "emotions"] by certain movements." 1/4

It’s not really that surprising that Darwin used the diagrammatic form in the Origin. In his private notes, he often scribbled diagrams to help him think through the general patterns that might be expected to emerge from evolutionary processes.

The diagram was more than a picture. He referred to it frequently in the text, clearly believing that the diagrammatic form rendered some aspects of evolutionary dynamics more clearly than text could. I’ve written about this in my dissertation, available on request.

Darwin’s publisher, John Murray, was usually quite generous about paying for maps, plates, and in-text images for D’s books, and D attended closely to his illustrations, so it’s surprising that the Origin featured only 1, a diagrammatic model of change through time.

OTD in 1859, Charles Darwin’s Origin of Species was published. He’d been working on a long treatise titled β€œNatural Selection,” but learning that Alfred Russel Wallace had developed a similar theory, he shifted toward a shorter β€œabstract.”

Asa Gray was born OTD in 1810. A devout believer in a personal God, G was also one of Darwin’s greatest champions.

In a correspondence spanning 12 years, G and D minutely explored what evolution says about God and free will. D could not accept G’s God, but was deeply torn.

Arthur Miller was born OTD in 1915.

He had a complicated relationship with The Crucible, never settling even on who was the central villain. But late in life, he offered this:

β€œI’m not really a moralist. I just make the assumption that certain things we do lead to catastrophe.”

I haven’t had a chance to read the article yet, but the abstract makes me think of Andreas Wagnerβ€˜s idea of sleeping beauties, mutations that lie dormant in the genome until changes in environmental circumstances, which can be much later, suddenly make them ecologically relevant.
