A life of π
March 19, 2016Posted by on
This week on Facebook a week of posts on the subject of pi (π) can surely only be of interest to a geek but don’t worry, there won’t be another week from me like this one until 2022. This week, beginning on Monday March 14, is known as world Pi (π) Day, which this year is 3.1416 (for those that use a non UK English notation).
Though as Michael Caine is wrongly attributed as saying, ‘Now there’s not many people know that’. I doubt that come tomorrow, the world would have been shaken by the riotous behaviour of those celebrating the advent of the day. Nevertheless, Monday’s annual event did result in the following π pertinent postings. (Incidentally — if the value of π is infinite: How can it be a constant?)
For those who, unlike me (apart from those befuddled moments brought on by old age) who are not geeky, there is always PI (π) Media. I’m sure that you’re wondering why the name PI (π) Media was chosen. Never short of an opinion about anything, I would hazard a guess that like the never ending π it’s intended to be a never ending source of online information. It may be of course that once a year it gets free publicity from us millions trawling the net annually in our never ending search for enlightenment regarding the never ending π.
Monday The wonderful world of Pi — The most decimal places of Pi memorised is 70,000, and was achieved by Rajveer Meena (India) at the VIT University, Vellore, India, on 21 March 2015. Is π only a means of getting nerds into the Guinness Book Of records? So what effect has π had on my life? That’s a difficult question as I either consciously (or otherwise) use it on a regular basis. In mental calculations as 22/7, which I now do less often as my brain sometimes stops communicating with me and π is included more accurately on my scientific calculators.
Tuesday How a farm boy from Wales gave the world pi — Well, perhaps not true in the sense that pi was already known to mathematicians of the 18th century, but probably true in the sense of recognising the infinite progression as an irrational number. The history of pi is really interesting (well, at least to me), especially The History of Pi and the link on William Jones who should be credited with giving the world the symbol π rather than pi.
Wednesday Pi might look random but it’s full of hidden patterns — And you geeks thought that π was just an irrational number!
