The inspiration for this site came from John Allen Paulos' book Innumeracy. I read the book back in 2008, but reading it again this past summer reignited the inspiration and turned it into fruition. In my lesson plan spreadsheet, I started a column of "tidbits" to share with my students; it's filled with mathematical fun facts, latest news, and stuff you see on here. I teach middle school mathematics, and ratios and proportional reasoning make up large portions of the curriculum, so I'm always comparing stuff, like tossing my flipflop onto this big Danish clog while visiting Solvang, CA, and wondering how big or tall the person wearing such clogs would have to be.
I'm most grateful to Jules Bonin-Ducharme (@jboninducharme) for translating the entries into French when it was the original site.
A million thanks also to Seth Reisner (@MrReisner) who double-checked all the numbers for me when it was the original site. It was his hard work that pushed me to revamp the site and make it more user-friendly.
