Since 1989 math and science geeks have celebrated the all important mathematical constant pi and used the day, along with other folks, as a good excuse to indulge in their sweet tooth while eating some pie. The society of physics students has also turned Pi Day into a celebration of support for undergraduate involvement in the physical sciences. Pi appears in more than just mathematical equations, it is also found in many science formulas. You can help support STEM by helping undergraduate physics students get a piece of the pi(e) through your donation. (If you don't know, I have a Bachelor of Science in Physics so I think this is a great cause.)The pi in this piece was made from some leftover pie dough from last year's Pi Day project.
