Steve and Mimi Omiecinski, the brains behind Princeton’s Pi Day.

Albert Einstein didn’t specify what to do with his body in his will, and he also didn’t leave any instruction for future birthday celebrations. But fear not: Mimi Omiecinski’s Princeton Tour Company has it covered.

Thursday, March 14, would have been Einstein’s 140th birthday and the date — 3/14 — conveniently matches the first three digits of the mathematical constant pi. The result? Pi Day Princeton, a day-long celebration of all things Einstein scheduled for Saturday, March 9, and additional events on the day itself, Thursday, March 14.

The event, first envisioned in 2010 by Omiecinski, owner of the tour company and a booster of all things Princeton, includes some Among the day’s many events are pie eating, pie baking, pi recitation (it’s an endless number so the sky is the limit), and Einstein look-alike contests, special tours and lectures, a pub crawl, and a performance by the Einstein Alley Musician Cooperative at the Arts Council of Princeton.

Among the highlights on March 9 is an Einstein in Princeton guided walking tour from 10 a.m. to noon; a discussion of memory techniques by a former world record holder for reciting the value of pi (to more than 10,000 digits), David Fiore, at 1 p.m.; and a book signing at the Public Library with Wil Mara, author of “Albert Einstein,” a children’s biography published in January, at 2 p.m.

On Thursday, March 14, Einstein-related events will include a tour of Landau’s Albert Einstein Museum at 102 Nassau Street, from 10 to 11:30 a.m., with T-shirt sales to benefit the new Einstein Museum in Ulm, Germany; and a talk and book signing with Seth Fletcher of Scientific American, author of “Einstein’s Shadow,” which follows a team of scientists on a mission to capture the first photograph of a black hole, a concept that springs from Einstein’s theory of relativity, at 6 p.m. at the Public Library.
