Gaussian elimination can be used to find the rank of a matrix , the determinant of a matrix, and the inverse of an invertible square matrix.

According to Wiki -

"In the parlance of jazz, a square was a person who failed to appreciate the medium, more broadly someone who was out of date or out of touch, hence the saying "be there or be square". In the counterculture movements that started in the 1940s and took momentum in the 1960s a "square" referred to someone who clung to repressive, traditional, stereotypical, one-sided, or "in the box" ways of thinking. The term was used by hipsters in the 1940s, beatniks in the 1950s, hippies in the 1960s, yippies in the 1970s, and other individuals who took part in the movements which emerged to contest the more conservative national, political, religious, philosophical, musical and social trends. It comes from the square representing a four-beat rhythm as shown by a conductor's hands."

I don't dig the last sentence, as a conductor's hand when marking a four-beat rhythm describes a diamond*, not a square. And plenty of beat and hippy music is written in quadruple time.

* I'm aware that a diamond can be a square turned through 45 degrees, but it'd still be described as a diamond.

I would describe the conductor's rhythm-shape as a flat-bottomed boat with 1 triangular sail.

It ain't square, though, is it?

That's what I meant - whenever I see a conductor do what a conductor's gotta do, his hand does not trace a diamond.

Got a link to add, while you're here?

Horace Silver's soul-jazz composition "Song for My Father" (1964) was quoted by Steely Dan in their "Rikki Don't Lose That Number".

And bloody good they both are, too.

Silver has the highest electrical conductivity of any element and the highest thermal conductivity of any metal.

About 1/3 of the silver produced worldwide is used in photography.

Since 1998 when about a third of all silver produced was used in photography the demand for silver has reduced to about 15% of world production. This is predicted to fall even further as less photographic film is being used year on year.

Steely Dan were named after a vibrator in William Burroughs "The Naked Lunch"

According to wiki:
For centuries, doctors had been treating women for a wide variety of illnesses by performing what is now recognized as masturbation. The "pelvic massage" was especially common in the treatment of female hysteria during the Victorian Era, as the point of such manipulation was to cause "hysterical paroxysm" (orgasm) in the patient. However, not only did they regard the "vulvular stimulation" required as having nothing to do with sex, but reportedly found it time-consuming and hard work.

One of the first vibrators was a steam-powered device called the "Manipulator", which was created by American physician George Taylor, M.D. This machine was a rather awkward device, but was still heralded as some relief for the doctors who found themselves suffering from fatigued wrists and hands.

They would get done for that, nowadays.

Legend has it that Cleopatra had two orgasms a day. She is also thought to have invented the first vibrator. She had servants gather bees into a box then she took the box and sat on top of it.

Sybian Egyptian style!

Cleopatra may have been poisoned by Augustus, accounts of her death by Asp bite don't seem to tally with the painful death that such a bite would inflict. It is thought that it may have been a mixture of hemlock, wolfsbane and opium that did her in.

Cleopatra's aria, in handel's Giulio Cesare, venere bella had it's tune taken from another of his compositions , "Un leggiadro giovinetto" , from his oratorio "Il Trionfo del Tempo e del Disinganno",

Handel is buried in Westminster Abbey. He was given a ceremonial burial with honours. The sculptor Roubiliac decorated his tomb.
