Plenty of math, music and pie in the face to go around at virtual ‘Pi Day’ festivities

THE BLUE LIGHTS flashed, the music kicked in and the chant began: “Three – one – four – one – five…”

It wasn’t a techno nightclub show or a cult meeting; it was the Exploratorium’s annual celebration of pi, also known as 3.1415, on Sunday, 3/14. The San Francisco science museum began the event in 1988 and held it online this year due to COVID-19.
