Pi Day and Pi Approximation Day are two holidays held to celebrate the mathematical constant π (pi) (in the mm/dd date notation: 3/14); since 3, 1 and 4 are the first three digits of π. March 14 is also the birthday of Albert Einstein and the two events are sometimes celebrated together.
(quote from wiki)
I was lucky to have a visit to Ulm, a town where Einstein was borned back in 1879 during my last trip to Germany.
Its a beautiful town. People are friendly. The weather is refreshing.
and of course the tallest church in the world - Ulm Minster
breathtaking architecture !
