Quote note (#357)


Millions of millennia ago, in our own Milky Way galaxy, but far upstream of where we are today, two neutron stars spiraled around each other, each embodying the mass of a sun but smaller and faster than a speeding planet. Each of these tiny gigaworlds, millions of times denser than our sun, had been produced, not by a mere exploding star, but by a far more powerful supernova. Each supernova, burning a nuclear fire with a far greater power density than a normal star such as our sun, had besides a neutron star also produced a cavalcade of new elements. For elements lighter than iron, this nuclear fusion releases energy; but for elements heavier than iron, including copper, silver, and gold, nuclear fusion requires a net energy input as well as astronomical power densities. Our supernovae were powerful enough to create many metals, including copper and silver, from the fusion of lighter elements. But they were not powerful enough to create gold. Gold awaited the current, far more powerful and rarer event. […] Our two stars, fortuitously set into collision course by two separate supernovae, approached each other and then, captured by each others’ gravity, entered a death spiral. They collided in an unimaginable explosion, unleashing a power density far greater than that of a mere supernova and trillions of times greater than if a mere mountain-sized asteroid had hit the earth. The collision was so intense that it created a black hole and a burst of extremely high energy light called gamma rays. Escaping the black hole along with the gamma rays was a spray of new, heavier metals, including gold. This gold-rich cloud in part expanded and in part coalesced, participating in the subsequent formation of new solar systems, including our own. Due to this collision of rare intensity, our unusual solar system was seeded with astronomically rare heavy metals such as gold along with the more common supernova products such as copper and silver. …

Quote note (#348)

Retrieved from four years ago (by XS’s favorite HBD-blogger), and still perfect in its outrageous realism:

Daniel Freedman was a professor of anthropology at the University of Chicago. For his doctoral thesis, he did adoption studies with dogs. He had noticed that different dog breeds had different personalities, and thought it would be interesting to see if personality was inborn, or if it was somehow caused by the way in which the mother raised her puppies. Totally inborn. Little beagles were irrepressibly friendly. Shetland sheepdogs were most sensitive to a loud voice or the slightest punishment. Wire-haired terriers were so tough and aggressive that Dan had to wear gloves when playing with puppies that were only three weeks old. Basenjis were aloof and independent.

He decided to try the same thing with human infants of different breeds. Excuse me, different races. …

You’ll never guess what happens next (although, actually, the readers here are almost certain to).

The dog-breed analogy is used quite often, but probably still not enough. It’s pitched at the correct cladistic level, obviously. In addition, since ‘labrador supremacism’ sounds immediately ridiculous it should contribute to chipping a little stupidity from the race discussion.

Vindicating Lombroso:

We study, for the first time, automated inference on criminality based solely on still face images. Via supervised machine learning, we build four classifiers (logistic regression, KNN, SVM, CNN) using facial images of 1856 real persons controlled for race, gender, age and facial expressions, nearly half of whom were convicted criminals, for discriminating between criminals and non-criminals. All four classifiers perform consistently well and produce evidence for the validity of automated face-induced inference on criminality, despite the historical controversy surrounding the topic …

If given the slightest opportunity, the monkeys will ruin everything:

From the Restoration in 1660, to the end of World War II, the Royal society enforced the scientific method. If you wanted respect and esteem as a scientist, you had to tell us new and interesting things, and you had to show everyone how you knew these new and interesting things from what you saw with your eyes and touched with your hands. […] After World War II, Harvard got the upper hand over the Royal Society, and you no longer have to show your work. Instead, your work must be approved by the most holy synod of mother church – in other words, must pass peer review behind closed doors. Peer Review is new. Attempts to root it in the past of science before World War II are artificial and contrived. Somehow we obtained almost all of science that matters before we had peer review, and since we have had peer review, things have started to go terribly wrong with science. Peer Review is science by social consensus, and Galileo told us that that does not work.

Quote note (#280)

Bacteria are often invoked as agents of ‘rhizomatic’ (horizontal) disruption of tree-like genetic lineages, so it’s intriguing to see them being proposed (p. 161-2) as cladistic engineers:

If two groups of the same insect ignore each other and only mate with their social circles, they should eventually split into distinct species. These splits occur all the time in nature, and the forces that cause them can take many forms. They could be physical obstacles like mountains or rivers. They could be differences in timing, in the hours or season in which animals are active. They could be incompatible genes that prevent two animals from interbreeding. Anything that stops animals from mating, or that kills or weakens the offspring of those couplings, can create ‘reproductive isolation’ — a gulf that drives species apart. And as [Eugene] Rosenberg had shown, bacteria can cause reproductive isolation, too. By acting as a living barrier that stops two populations from meeting up, microbes could potentially drive the origin of new species. …

Quote note (#267)

Back to basics:

Are there countries with low average scores that tear up the technological track? Mostly not – generally, fairly high average IQ seems to be a prerequisite for creativity in science and mathematics. Necessary, although not sufficient: bad choices (Communism), having the world kick you in the crotch (Mongols), or toxic intellectual fads can all make smart peoples unproductive. […] The exceptions, such as they are, seem to be a result of strong population substructure. India has a low average IQ, but there are distinct subpopulations (castes) that apparently have much higher IQ – although I’d love to see some decent studies on this. With numbers. …
