Happy International Pi Day! For the unacquainted, Pi Day pays tribute to the mathematical constant π, or 3.14159... (which is why I posted this at 1.59pm. smile emoticon ). But even if you're not a math lover, no need to be "Pi-Seh".

This year, Pi Day coincides with the start of the school holidays. Science Centre Singapore has plenty of activities planned
