the life of π

Whereas astrophysics suggest that extending out the significant digits to thirty-nine decimal places would be at the level of precision to measure the circumference of the known Universe to within the breadth of a hydrogen atom, we quite enjoyed the overkill and ambition, as reported by the Guardian, of a team of Swiss mathematicians that have calculated out the transcendental, irrational number, also known as Archimedes’ Constant and whose use of the Greek letter to symbolise it first attributed to Welsh professor William Jones in 1706, to sixty-two trillion places for the accomplishment in itself plus the bonus facts and anecdotes. Not only is it fiendishly useful to understand and is embedded in all sort of applications, there’s quite a bit of lore attached to pi. There’s its elegance in comprehending a bit of the Cosmos, cameo appearances and an infamously misguided attempt in 1897 by the Indiana state legislature to round it up to 3.2 and be done with it.
