In this edition of Super Science, Drew and the Exploratorium's Science Educator Lori Lambertson dive fork first into the science behind this irrational number.
"Pi is a decimal series that goes on forever with no repeating digits. We represent it with a Greek letter pi," explained Lambertson. "Pi's accessible to all of us."
Archeological records indicate that pi has been known and utilized for over 4000 years. Mathematicians, scientists, astronomers, artists, and engineers have used and are still using pi for all manner of creative and practical purposes.

"Everyone's invited to come parade around (our) pie shrine and then get a free slice of pie at the end," said Lambertson. "We parade around it 3.14 times because of pi and we also sing Happy Birthday to Albert Einstein because Pi Day is March 14 (which is) also Albert Einstein's birthday.
