1592 Was THE Ultimate Pi Day BUT No One Would Have Known That — 3/14/1592.

by Anura Guruge



The first 10 decimal digits are
3.141592653 …

Two reasons why nobody in 1592 would have realized this.

  1. The 3/14 notation for month/date is primarily American and would NOT have been widely used in Europe in the 16th Century.

  2. The value of Pi to 7-digits had been calculated by then BUT was NOT widely known.

Worth thinking about.

The first ‘Pi Day’ was celebrated at the ‘Exploratorium’
in 1988.

Amusingly, for a mathematical event at that, they counted wrong — forgetting that it has to be counted inclusively. Counting 1988 this would be the 29th annual Pi Day, NOT the 28th. That is FUNNY.

March 14, 2016 “PI Day” Of THE Century — The Only One In Your Lifetime.

March 14, celebrated as ‘Pi Day‘, hopefully with real pies, happens each and every year on 3/143.14 the first three digits of π.

IF you wanted to be lax about it last year was special too = 3/14/15 BUT that did NOT sit well with mathematicians because π to five decimal places isn’t really 3.1415. That is because the next digit in this infinite sequence is ‘9’. So IF we are going to be mathematical, as we have to be in this case, π stated in five digits is 3.1416. Bingo.

No to be fair this ONLY works IF you still think of years in dates in 2-digits. I ceased to be a 2-digit man in 1998 with Y2K looming. Since then, as you may have noticed, I always spell out my years in 4 digits (because 2-digits no longer make sense).

But it is cute.

So you get it, right? Next 3/14/16 will be in March 2116. Hundred years from now. That is a long time.

Barnstead to their credit did have a ‘Pi Day’ event replete also with pies for those that get hungry just thinking about math.

Though the new pope, who was in my published list of top 10 picks, was elected the day before, life continued to be crazy for me with interviews and Web updates. So I got Deanna to take the kids. They went. They like it. They were impressed. They had fun. They learned a few things. Teischan got to do some of the Grade 6 puzzles. She was thrilled. It was good. Kudos, Barnstead.

On the other hand, in Alton, Deanna got told off, in public, for asking on the ‘Alton Central School’ (ACS) Facebook page whether ACS had any plans for pi day. Yes, she was chastised. Why? Because she had done it via Facebook! She was told that matters such as that need to be dealt with by telephone. How quaint. Even the pope uses Facebook and Twitter and ACS demands that you can only ask questions via the telephone. I don’t know who actually told her off. I think it was the administrator of the ACS Facebook page. I don’t use Facebook. So I don’t see this stuff. Deanna thinks it was the Principal that told her off (but it could have been the IT ‘dept.‘) — and said that she should have telephoned the person responsible for curriculum. Wow. Talk about being officious. I wouldn’t have thought that having a pi day was really a curriculum issue. But, what do I know. If it was the Principal that told Deanna off I can fully understand. She has told me off too. Yep, well and truly put me in my place. Made me squirm and suck my thumb. Well, Deanna is not happy. She is not sure why ACS has a Facebook presence if you can’t actually ask bona fide school related questions. C’est la vie. I guess the best thing in future is to send all questions in writing, in triplicate, to the Superintendent, by certified mail. Will do.

But, back to BES. Here are some pictures that Deanna took.

Barnstead, To Their Credit, Is Celebrating ‘Pi Day’. Alton Is Not Even Having A ‘Pie Day’. They Are Having Nachos. No Kidding.

Tomorrow, 3.14, i.e., March 14 (3/14) is World ∏ Day.

Many school districts exploit it as a good excuse to revel in the sheer sensual pleasure of mathematics.

I was delighted to see that Barnstead is doing so. Kudos, Barnstead.

Not so Alton. I had at least hoped that Alton might make it Pie Day. Not even that. We checked, printed timetable and online. No mention.

But, then again, Alton probably doesn’t have to celebrate math.

I went and just checked to make sure. Alton’s much vaunted Prospect Mountain High School (PMHS). 44% of Juniors proficient in Math in the NECAP testing! Is that good? They probably should be treated to pies. Lots of them.

Next Thursday, at least in the U.S. (and maybe in Canada, though I am not sure whether they actually have calendars up here), it is 3/14 or 3.14. In the rest of the world, in the U.K. and Sri Lanka, it is 14/3 or 14.3. But, since the U.S. rules the waves 3.14 is World Pie Day — and for those of you who are not into pi, just celebrate it as World Pie Day and have a pecan or meat pie and think of POOR me.

Pi.

I love Pi. Always have since I was introduced to it when I was about 8. I also love pie, both sweet and savory — but alas and alack I haven’t touched a pie, not even nibbled on the crust of one, in 6 weeks! Yes, I have managed to lose 11 pounds. I am down to 178 pounds. So, I am no longer as obese as I used to me, but that at the expense of apple, pecan, lemon and cherry pies, not to mention savory meat and French pies. Getting old sucks. Being pre-diabetic just makes it worse. But, I will celebrate Pi.

Pi is one of the two most important, pivotal, sacrosanct, physical constants in the Universe. The other ‘c’ – the speed of light (as in e = mc²). But, most people can’t remember c. c = 186,282 miles per second. I am not sure how many people even remember ‘G’ — the gravitational constant.

Pi is neat. Very neat.

When I want to have fun with my brain, I try to imagine early philosophers, who believed that all things in nature, divinely inspired, had perfect order. Just think of them, laying out little pieces of string trying to correlate the circumference of a circle to its radius. They must have thought that they were doing something wrong. How could it not be a exact number. Was God playing games?

I try to imagine whether in another world, another planet, in another galaxy, or even in the Milky Way, Pi might be different? I don’t think so.

Having been born a Buddhist, I was never expected to believe in an almighty, all seeing, all powerful God. Thank God. But, Pi to me, was yet another example that there is no all knowing, all seeing creator ‘up there’. Because, nobody with even a modicum of sense would have come up with Pi! Pi is chaotic. That is its abiding, never ending beauty. Infinite, mysterious, beguiling and beautiful. Pi.

Growing up, given my age, we didn’t have electronic calculators. I got my first electronic calculator, a bulky Casio, around 1972. I think it cost my father U.S. $200. I started with using 22/7 for Pi.

In 1971, in my first year at University, doing computer technology, one of the assignments we had was to calculate Pi to as many digits as we could in 3 seconds of compute time. No, we didn’t have dedicated computers. The PC was exactly a decade out. We used time-sharing systems. Computer usage was measured by the Milli-second and billed. 3 seconds compute time, which might equate to 5 minutes of elapsed time, was a lot. Oh! We also programmed using punched cards. They were batch jobs. You submitted a deck of cards and waited for that job to be run and the printout to be delivered to your pigeon hole. I can’t remember what algorithm we used. We programmed it in Fortran IV. I do remember spending 2 weeks refining and polishing my code, 3 to 4 times a day, to get more digits in the 3 seconds we got. Yes, I have to confess, I beat the rest of the class. I was a zealot. Total maniac. I worked on my programming like a man possessed. It was beyond an obsession. I had a very unusual 3 years at University for my 1st degree. To say it was WILD would not even capture 10% of it. There were those that claimed that I was horizontal for 75% of time at University — and it wasn’t inebriation because I didn’t take up alcohol until I got my 1st degree (though the drinking age was 16 or lower) and I never did drugs (though my inseparable best friend, 1968 to 1969, when living in Paris, was Charlie ‘Byrd’ Parker Jr., yes, THE Byrd’s son). [I think they exaggerate. It was probably only about 60%, though it might have looked longer to others.] Yes, I could program while horizontal and always had a notebook by my side to write down algorithms that would come to me in my sleep or in moments of inspiration. Yes, I was strange, even more or than now. Plus, I had a shaggy, uncut head of curly black hair, and an unwashed, smelly genuine, bona fide, from Afghan coat. No wonder IBM offered an ‘unconditional’ job when I was 19. With or without degree. Whenever. Just call this number. And I spent 10 months trying to avoid that … writing letters to all the African game reserves asking for a job as a game warden! Just think. If I had got ONE offer, I would have been gone. None of this. All their fault.

Anyway, next Thursday. MATH DAY. Pi day. Alas I will still not indulge with a pie. But, lets celebrate.
