I pulled up some numbers for Google Cloud Platform server and storage pricing to see how much it would cost a layperson to do the 31.4 trillion Pi calc.

I didn't look into network costs, or extra time for configs/restart - just raw computation time. I get a price of $173,335.76
This is using standard pricing, not pre-emptible pricing, which is a lot cheaper.

Here's the URL for GCP costs:

cloud.google.com/compute/pricing
Here's some costs on hardware, at just over $200k. This is raw list pricing - Google and other cloud providers obviously buy this stuff at super cheap pricing. This is ballparking, based on the loose specifications cloud providers give for instances and configurations.

For #PiDay + #WomensHistoryMonth, I honor an eminent, glass-ceiling-breaking mathematician, Dr. Loretta Marion Murray Braxton. In the 1950’s, her 1st math prof in college in VA told her that she was in the wrong classes, b/c "only boys took higher-level math classes."1/14
Undeterred, Loretta Braxton won an NSF to do an MS in math in a top program at the University of Illinois, obtained a doctorate, and taught the 1st African American who formed a billion-dollar company, Reginald Lewis. #PiDay #Fearless 2/N
As a math teacher, professor, and 15 years as chair of the math department at @VSUTrojans, Loretta Braxton mentored several generations of math students, many of whom became teachers + college or university professors themselves. #BlackAndSTEM 3/14

It’s #PiDay… but it’s also #worldkidneyday! Critically important issue to me personally and so many Americans. 1/8
Many people with #chronickidneydisease don’t know it and it is major and rising cause of morbidity and mortality in the US and globally – we must do better! #heartyourkidneys #worldkidneyday 2/8
Today is also great opportunity to pay tribute to all of those courageous and generous people who have donated kidneys. Living donors should be better supported and we are working to make this happen. #worldkidneyday 3/8

One of the many great things about Pi is that it's algorithmically compressible. You can express the idea of Pi using far fewer characters than are actually contained in its numerical expression (which would be an infinite number). #PiDay 1/
Between 0 and 10 (say), there are an infinite number of rational numbers: those expressible as p/q, where both p and q are integers. The rationals are "dense" - given any number between 0 and 10, there is a rational number arbitrarily close to it. 2/
But there are infinitely more irrational numbers, those that can't be expressed as p/q. It's a bigger infinity than the number of rationals. The rationals are "countable," the irrationals are "uncountable." There are a lot of irrational numbers out there. 3/

MEGA THREAD. Happy #PiDay to everyone.

Let's start with the simplest calculation of Pi - the ratio of circumference to diameter for round objects. wired.com/2014/03/calcul…
2/ If you want to do this calculation of Pi, just find a bunch of circular objects of different size. Use a string to wrap around and measure the circumference and then measure the diameter. Plot C vs. d - the slope is PI.
3/ But wait! #PiDay is only Pi in the USA where we use date format of month/day/year.

For everyone else, today is 14/3/2019 - which is NOT Pi. I suggest the other Pi day is July 22 (22/7/2019) since 22/7 is a great fractional representation of Pi. wired.com/2011/03/what-i…

Very excited to hear @RLindsayComics here at @HMSCountway today on "Reclaiming the Patient Narrative through #GraphicMedicine" beginning momentarily! @MCPHSArtScience @HachetteUS @NoetheMatt Flier for @RLindsayComics's talk at Harvard Medical School
There’s pie for #PiDay!
Dien Ho of @MCPHS Center for Health Humanities thanks @NoetheMatt for today’s event and starts the talk.

#Pi is underrated as no one can truly comprehend the infinite transcendental & irrational value of π
Pi is an infinite number therefore w/in that number contains Your:
Birthday
Social Security
Drivers Licence
Phone Number
Every Address You've Lived
etc
Gen 1:1
#PiDay2019 #314Day
There're 22 letters in the Hebrew AlephBet
7 is the # of completeness & perfection (physical & spiritual)
22/7 = 3.14 = #Pi
Pi is an infinite # that is contained inside of a finite # we can measure the Diameter & Circumference
Every letter has meaning, number & a symbol as well.
The numerical values of each of the Hebrew letters & words of Genesis 1:1 then apply them to this formula:
# of letters x the product of the letters
divided by
# of words x the product of the words
28 (2.3887872 x 10^34)/ 7 (3.0415353 x 10^17) = 3.14155 x 10^17
You get #Pi

Some people have asked about #PiDay, so here are some thoughts (warning: long-ish thread).

The number π ≈ 3.14, that is, the ratio of circumference to diameter of any circle, has continually captivated mankind since at least the ancient Babylonians four millennia ago.
It even appears in the Hebrew Bible, where King Solomon’s Temple is described as containing a perfectly round ritual basin (“Molten Sea”) measuring exactly 10 cubits across and exactly 30 cubits around. This may suggest that π should be 30/10 = 3 identically,
a mistake in the scripture, but a clever ancient midrash, or commentary, by the 2nd century Rabbi Nehemiah says that this passage in fact conceals in cypher the thickness of the basin! For the last 30 years or so, people around the world have been celebrating “Pi Day”

In honor of #PiDay - JOKES!
Watch out - Mr. Magoo is going after those Confederate statues! #PiDay
Here is Mr. Magoo delivering a pay-off to Stormy Daniels. I was with Brian Williams when I took this with my cellphone. Yeah, that's right. My. SMARTphone. #PiDay
