That's a lot (more) pi!

Mrs. Halfacre and the class admire 159 digits of pi.

Most of us know that mathematical pi is 3.14, we might know that pi is the ratio of a circle's circumference to its diameter, and, after that, well, we might be lost. Not the math whizzes in St. Mary's Upper School. Today, in celebration of Pi Day (usually celebrated on 3/14 -- get it? -- but not here, since we were on spring break) students in Mrs. Halfacre's Precalculus class brought in pies of every description, from pecan to brownie to chess, to share. The highlight, though, was a contest to see who had memorized the most digits of pi, a number that is infinite, and that computers have figured out to the millionth place. Junior Marie Peeples won handily, having spent time in geometry class last year memorizing a whopping 159 digits of pi. Below, what 159 digits of pi look like ... it took Marie about two minutes to remember them all, and all correctly, said Mr. McCalla. Way to go!

Just checking: Yep, she got them all correct.

Next up? A pie-eating contest between the Upper School math teachers and science teachers, tomorrow (outside, weather permitting) during the last 15 minutes of lunch.

Sophomore Kate and her pi/pie(s) on Wednesday. She got to 95 digits ... yay, Kate!
