Happy Pi Day, everyone!
To celebrate, our friend Samantha brought in her knitted Pi blanket to share. After the first hexagon with the letter π embroidered on it, the first 127 digits of Pi are shown using the resistor color code to represent the value of the digit. Samantha is donating this quilt to the Project Linus, an organization that gives blankets to children who are seriously ill, traumatized, or otherwise in need.
For those in the San Francisco area, the Exploratorium is celebrating the 25th Anniversary of Pi Day from 1 pm to 3 pm in front of their soon-to-open new location at Pier 15.
Happy Pi Day! Pi day was just made official. In honor of National Pi Day, we present a pi trivet, perfect for cooling your Apple pie (or pi pie) on.
Besides just the letter pi, The number pi up to the first thousand digits after the decimal are laser engraved into half-inch thick cork. The overall size of the trivet is about seven inches, square.
This cork is actually gasket material from McMaster-Carr, which has a wonderfully smooth and even surface. Compared to many of the other cork materials that we have seen– like that used for many cheap trivets– this has very little pitting and the surface shows fine detail very well.
