March 14 is Pi day. It occurs on the 14 day of the 3rd month, which is equal to Pi’s approximation 3.14. On Pi day, we appreciate the number and eat a slice of delicious pie. Pi is the mathematical constant defined as the ratio of a circle’s circumference to its diameter. The circle of fifths in music theory is the geometric shape of a circle. The circumference of a circle is equal to C = 2𝜋r. In the Stephon Alexander book called The Jazz of Physics: The Link between Music and the Structure of the Universe. Alexander explains how the jazz master saxophonist John Coltrane developed a more advanced version of the circle of fifths, called ‘The Coltrane Circle’. The Coltrane Circle diagram is the same geometric pattern that inspired Albert Einstein’s quantum theory. Today is also the 142nd birthday of the famous artist-scientist Albert Einstein, who was born March 14, 1879.
