Happy Pi Day!! (2019-style)

The value of the number pi has been calculated to a new world record length of 31 trillion digits, far past the previous record of 22 trillion.

Emma Haruka Iwao, a Google employee from Japan, found the new digits with the help of the company's cloud computing service.

The calculation required 170TB of data (for comparison, 200,000 music tracks take up 1TB) and took 25 virtual machines 121 days to complete.

BBC.com, news, 3-14-19, Emma Haruka Iwao smashes pi world record with Google help.

Happy Pi Day!!

Thanks to a quirk of date naming convention here in Los Estados Unidos (we are mm/dd/yyyy oriented), today happens to be "03/14/19". Since the first few digits are "3.14" somebody, sometime, somewhere, called it "Pi Day". Totally irrational, just like the number!

Most people don't get to play with Google's cloud services. But hook a bunch of cpus up and let the unsigned digits get to flying and look what happens. Four months and only 170 terra bytes later, 31 trillion digits!

According to Wikipedia (source of all these numbers), only 2,000,036 digits were known in 1981. In only 2 years, that number doubled. The previous record of 22 trillion, for comparison, used 75 cores, 120 TB, and took 105 days. The increase is probably more to do with computer architecture more than anything else. Iwao had 30 TB of SSD at her disposal while the other guy only 1.25 TB DDR4!!

It is kind of amazing how far technology has advanced since 1980. Every now and then, we need to sit down to a slice of pie, and not take all thech for granted and wonder about it all!

I find geeky things like this fun. So once again, Happy Pi Day!!

Did you know that 3.14% of sailors are PIrates?

Yeah. Some things are simply amazing

You'd have to be irrational to not celebrate Pi Day!

a reply to: CriticalStinker


LOL!

According Wikipedia (as Abraham Lincoln once quipped, "You can't trust everything you see on the internet"), Pi Day started in San Francisco on 3/14, 1988. I thought it was around longer than that.

They even have their own web site!

PiDay.org.

Even other places are cashing in on the day. Like the tweet about $3.14 pizzas! Who knew?!!

Besides pirates, of course!

a reply to: TEOTWAWKIAIFF

Yeah, we celebrated Pi-Day in my nerdy high school in the early 80's, so just because they made it all "official" don't mean squat.

I suspect it's been around for a good many decades in the 20th century...

ah, the 20th century... back when pi tasted good.

26. Even comedians use pi to make people crack at their jokes. John Evans, a comedian, once said in his performances, “What do you get if you divide the circumference of a jack-o’-lantern by its diameter? Pumpkin π.”

piday.org 36 Pi Facts.

If they had just named it "36 Crazyfists Pi Facts..."

As if someone is going to punch in 31 trillion digits to make a calculation.

At work we got Village Inn pies to choose from. They were pretty good. Very sweet though.

There's an app for that!



a reply to: chris_stibrany

The VI sweets are too sweet for my taste. Except the pudding based ones. I think it is the whipped cream.

a reply to: TEOTWAWKIAIFF

Someone should use Pi for a bitcoin type Idea. That way it can be calculated as long as there is interest. The person who makes it should give me a cool million Pi coin for thinking of it first.

Happy Pi-Day!

a reply to: StallionDuck

Kind of gives a new definition to being Pi-blocked!



a reply to: Peeple

And to think, I was going to be witty and smart about this...



But yours beats anything I could have said out of the water!

Well played!!

Pi day is interesting
Einstein's birthday
Hawking passed away on this day in 2018
2 of the greatest (if not THE greatest) physicists that have ever been .

This will blow your brain wide open:

I think you're right. I had the 'silk' flavour with chocolate creme and it was pretty intense. It made my blood feel hot lol. diabetes here I come ...no no no.

a reply to: Baddogma

Weird city!!!

First, thanks for confirming this was a "thing" before somebody staked their claim on the internet.

Second, I DID NOT SEE THIS POST UNTIL THIS MORNING!!!

I had the reply to Critical, then my pumpkin pie may taste like sewer rat but I wouldn't know because I still wouldn't eat the dirty... response. I came back several times yesterday and it was TEOT, TEOT, Neo. Wth??

So Pi Day came with a side of woo!!

All praise the MetaCafé!

ETA: Or somebody is fooling around with the Worlds first Time machine invented - well a time machine of sorts.

didn't hawking die on pi-day a year ago ?

Disco!

Universe has a sense of humor, it seems. Einstein's birth day and Stephan Hawking's passing both March 14 (different years, of course). A weird physics version of Mark Twain and Haley's comet (take that ME!).

I saw some weird blog post where this guy adds and subtracts numbers in a weird mish-mash style to "show" connections between things. After a bit, it gets to be too much to follow. I will leave it at broad brush level.

a reply to: dfnj2015


That was fun. "Limited literature," never knew that as a style just that some authors used it. Probably to most famous is Dylan Thomas, Do Not Go Gentle, poem. He limited both the style of poem and the rhyme scheme.

I like "e prime" where the word "is" is not used.

Here's one last cool thing from Pi Day.

[Created] for Pi Day (March 14), music software programmer Canton Becker has crafted a million-hour song based on Pi that unfolds generatively on a virtual tape deck.

Titled “Shepard’s Pi,” the song combines two of Becker’s favorite infinities: Pi, and an auditory illusion called a Shepard tone, which he describes as an “unsettling sonic illusion of a pitch that climbs or descends forever, never reaching a top or a bottom.”

motherboard.vice.com - Musician Creates a Million-Hour Song Based on the Number Pi.

There is web site that has the song (link in article) that I can't get to or would have said if it was any good. Anyway, the concept is neat as the algorithm creates the digits of pi they are converted to the scale and the tune plays. Instead of storing the notes (data) it is generated at the website (only http, which is why I am blocked). The whole thing is spelled out in the article.

Btw, it would take 114 years to listen to!
