SAN FRANCISCO, Calif. (KRON) — Pi Day is taken very seriously in San Francisco.
So seriously that the numbers of Pi were actually seen in the sky over Twin Peaks on Sunday.
Each number was on a balloon and tied to a string. The string of balloons then floated into the San Francisco sky.
James Nicovich and his friends thought of the creative idea that put a smile on people’s faces.
Pi is a mathematical constant, represented by the Greek letter “π“. It is defined as the ratio of a circle’s circumference to its diameter.
It appears in many formulas in mathematics and physics.
Now, every 14th of March (3/14), people celebrated the mathematical constant Pi and eat lots of pie.
Happy Pi Day!
