"Freud" on Netflix

This German-language series (with English subtitles) has lots of goodies: sex, violence, nudity, more sex, more violence, ... . It's engrossing, but historically inaccurate in the extreme. Kids might want to program their entertainment centers so parents can't watch.

history of science and astrology

I get pissed off every time I see the astrology column in my daily newspaper. However, my attitude toward astrology is tempered by an enthusiasm for its history.

Why would I care about the history of such nonsense? That's a fairly long story. Those with short attention spans may not wish to read further.

As a physicist, I am naturally interested in the history of my subject, which is all tangled up with the history of mathematics and astronomy. Of course I am interested in the scientific revolution of the 16th and 17th centuries, including the work of Copernicus, Tycho Brahe, Galileo, Kepler, and Newton. All but the first and last scientists on this list were court astrologers.

The king of Denmark supported Tycho Brahe's career as an astronomer only because Tycho's meticulous observations of stars and planets would supposedly lead to better horoscopes.

Galileo and Kepler were also expected to cast horoscopes in the regions (not yet nations) of Italy and Germany, respectively. Around the turn of the 17th century, Kepler landed a job as Tycho's assistant at Prague, in the court of Holy Roman Emperor Rudolph II. Tycho gave Kepler his observations of the planet Mars to play with. When Tycho died (1601), Kepler became his successor as Imperial Court Mathematician. The Mars data were crucial for Kepler's subsequent discovery that planets move in elliptical orbits. And that discovery led to Newton's law of gravitation.

To summarize: if it weren't for astrology, Kepler and Newton would never have made their most important discoveries.

About Lionel Mandrake

I study, play the piano, play chess and go, and enjoy the company of my wife, children, grandchildren, other relatives, and friends. I am a perennial student at a school where they let me attend classes and use the library for free (because I'm old). My serious reading includes math, science, history, and biography. I enjoy science fiction and mysteries, which my wife and I refer to as "mind rot". And now on to politics. I hated Nixon and Reagan. I think W is a war criminal and was easily the worst president in US history until Trump came along. Trump and Sessions should be tried for having separated small children from their parents, which was a crime against humanity. I will support any candidate who is a "dove". I support "plan B" without prescription for girls of all ages. I support free abortion on demand, without delay, and without the requirement to notify anyone, for all women and girls who want it. I think it's time to repeal the Bush/Trump tax cuts for corporations and the very rich.
