Pi Days of Yore: Activity Suggestions Submitted by Teachers, Students & Everyday People
Some examples: (1)We play pi shuffleboard. I draw 3 big circles on the floor, inside of each other and the kids use rolls of masking tape as pucks. They toss and/or slide circles of tape [identifying marks on side] to see who gets closest to center. Players each have 3 circles of tape that they slide to remove others from center. The winner then challenges the next 3 players until we declare Pi shuffleboard winner.(2)For our Pi Day, my school asked all the faculty members if they would be interested in being “pi’d” and their name was put on a plastic jug. Students would place money in their jug throughout the week and the teacher/faculty member with the most money got pi’d at an all school assembly. We raised a total of about $400! We donated all the proceeds to multiple charities. more »
The Touch of a Ladybug: Creating a New Class of Flexible, Stretchable Electronically-sensitive Synthetic Materials
Restoring some semblance of the sensation of touch has been a driving force behind Stanford chemical engineer Zhenan Bao's decades-long quest to create stretchable, electronically-sensitive synthetic materials. Such a breakthrough could one day serve as skin-like coverings for prosthetics. But in the near term, this same technology could become the foundation for the evolution of new genre of flexible electronics that are in stark contrast with rigid smartphones that many of us carry, gingerly, in our back pockets. more »
The Gender Gap in Economics: Swarthmore’s Amanda Bayer Discusses Sexism in the Profession and What To Do About It
Amanda Bayer: "The percentage female at the undergraduate level in economics is well below the percentage female in other social sciences, in business, in humanities and even below the percentage female in STEM fields. Economics is an outlier...There's a huge misconception that it's the math component of economics that's keeping women away. And that's actually not the situation. About 45 percent of math majors at the undergraduate level are women. So, women major in math at a higher rate than they do in economics. Other studies with regression evidence show that math isn't the factor that explains the gap."

Sally Yates, a "Truly Noble, Heroic Figure", a Woman of the Year
Editor's Note: We thought about Sally Yates again today when journalist and commentator Mike Barnicle (on Morning Joe) referred to the former Acting Attorney General as a "truly noble, heroic figure" and so decided to rerun the Harvard Law School article on her speech to the graduating class. "Being bold, taking a risk and owning it, isn't easy to do, and the instinct for self-preservation may continually draw you to the safe, risk-free course," she said. "But I urge you to resist that instinct. Not only is a life of hedging your bets unsatisfying, but it means you're unlikely to make much of a difference." more »
