Pi Approximation Day (yesterday)
Of all the random dates already in my calender, I have just added another! The so called Pi approximation day, which I missed this year, is on the 22nd of July and is so ‘celebrated’ because it mathematically gives a close approximation (divide 22 by 7) to the true value of Pi. Oh well, this time next year (sans one day) I will make a Pi pastry and who knows what else…:)
