Sometimes math does things we can’t explain.
One of those things is that pi keeps appearing in seemingly unrelated theories. For example, randomly drop needles onto a grid, such as a tiled floor, and the probability that a needle will cross a line relates directly to pi.
It’s called Buffon’s Needle Problem and it’s an early example of geometric probability.

About the Designer: Mary E. Rose
Mary learned to knit as a young child and it has had an impact on her life ever since. As a teen, when her friends were getting jobs at fast food restaurants, Mary worked at her LYS, where the hours and working conditions were much better.
As with many knitters, when she couldn’t find patterns for what she wanted to knit, she started designing her own.
She currently lives in Central Ohio with her three children, who also craft. She can be found on Ravelry and her blog, or with knitting needles in hand, guarding her stash.
