JMA-PSOS

On CBC Rado last Saturday’s Quirks and Quarks a lot of interesting topics were covered: long Covid effects on the central nervous system (as the body of the iceberg who’s visible portion we only glimpsed in the past few years), how bonobo individual aggression is mainly directed towards other males and is individual, and about the Mars-Earth 2.4M year cycle that affects Earth’s eccentricity and climate (we are in the middle of it now at its lowest effect). The last topic prompted me to look at other long cycles that affect Earth’s eccentricity: Venus-Jupiter 405ky cycle (also at its ebb now having peaked 216ky ago). There are also the Milankovitch cycles that impact climate. I wonder if all the current climate models account for all these cycles (which they probably did).

The quibble I had was with John Holt’s suggestion that an unschooled child can make contributions to quantum physics (on a Rewing 1983 episode from CBC Ideas) on which I commented as a reply to a post I made quite recently on this blog.
