Tafelmusik

An Illusory Intertwingling of Reason and Response

Tafelmusik is a look askance at life. It is a chronicle of the Dance of the Good Thing, a part in which I strive always to take. Here lie my musings, my thoughts, my beliefs, and my desires. Join me. Dance.

Algorithms for Pi

Just a note to self, so I don't lose some of these sites I've found.

I've been looking at algorithms to calculate π (pi) recently. I've not actually installed and learned anything like GMP, MAPM, MPFR, or other so-called "bignum" libraries, so I'm pretty much limited to the digits that can be stored in a double. *sniff* Well, I'll get around to it eventually, eh?

So, the major algorithms I've found are as follows:

I've implemented Aristotle's algorithm and Gregory's series, and filled a double with accurate values for π (pi) fairly quickly. Actually, the expansion of Gregory's series rand several orders of magnitude faster. I suppose now I should install GMP and play with actual numbers instead of these piddly little doubles.

Philosophy of Love and Beauty

I debated entitling this "Erotology and Calliology" or "Aphrodology and Bellology," but declined. You may refer to it as such if you wish . . . I rather like the term "calliology", and may continue using it.

Anyhow, I'm trying to keep a few reference pages available to which I may direct people when certain topics come up in conversation. I find it saves words and time, as well as ensures consistency on my part, if I'm able to cite what I've actually written down.

The following entries are those which have some bearing on my philosophies of love and beauty. Since you're able to read it all right here, I'm not going to rant on the topic now. I'll save that for what I've already written.

Suffice it to say that I worship women . . .

Movies to See

I have a ponderous list of movies Iíve been assigned by various friends and enemies:

I've been told . . .

  • Dangerous Liaisons: Also from CD. Apparently there is some underlying artistic necessity to my watching it.
  • A Beautiful Mind: Yeah, the crazy-mathematician movie. Thatís my kind of main character.

Might I Recommend . . .

  • A River Runs Through It
  • Casablanca
  • The Spanish Prisoner
  • The Hitchhikerís Guide to the Galaxy

I watched . . .

  • Lion in Winter: CD assigned this one to me. Itís got Patrick Stewart in it, who is actually a much more skilled actor than he was ever required to be on Star Trek. I finally watched it. Highly recommended!
