Happy Pi Day! It’s 3.14! Apparently apple pie with green chile is NM’s official pie (who knew!?)—but we all know it’s Frito Pie! Since we’re taking a moment today to celebrate mathematical sequences, let’s talk for a moment about how important STEM education is! https://t.co/kHg8zUtn5L
Today is National Pi Day π
As a tradition, my daughters always get pies every time since they recognized the day.
How many digits after 3.14 you can say out loud? My eldest can still do 20, I think. 😁😁😁 https://t.co/f41Yy1LzTK
What an amazing scene today in Santa Cruz as Food Not Bombs celebrated 1 full year of *daily* food and water distribution during the pandemic, despite repeated evictions and roadblocks from the city. There was live music and pie for Pi Day, and people got needed meals + supplies. https://t.co/G3Ob1ovquY
