⚡️ Quick Tips and Fascinating Facts About 50 Trillion Digits of Pi

Welcome, fellow math adventurers and tech enthusiasts, to the wild world of extreme numbers! Before we dive deep into the computational abyss, let’s get our bearings with some truly mind-boggling facts about the 50 trillion digit Pi record. If you’re curious about how this compares to other massive computations, check out our exploration of What Are the First 1,000,000,000,000 Digits of Pi? 🤯 (2025).

  • The Mastermind: The 50 trillion digit record was set by Timothy Mullican in 2020, an incredible feat achieved not by a massive corporation, but by a dedicated individual in his own home.
  • Data Overload: To calculate the digits, Mullican needed a staggering 281 Terabytes (TB) of temporary storage. The final number itself, once computed, took up 38 TB. To put that in perspective, 38 TB is enough to hold over 8,000 HD movies! 🎬
  • Time is of the Essence: The entire calculation took approximately 8 months of continuous computation on his custom-built server rig. That’s dedication!
  • The Software Secret Weapon: The magic behind this feat is a program called y-cruncher, developed by Alexander Yee. It’s the go-to tool for number crunchers and has been used for virtually every Pi record in recent history.
  • Cost-Effective Genius: Mullican aimed to complete the project for less than 5% of the estimated cost of Google’s previous 31.4 trillion digit record. He successfully used second-hand enterprise hardware to keep costs down. Frugal and brilliant—we love to see it.
  • Near Disaster: The project almost failed! As Timothy Mullican shared on his blog, “Due to severe weather, I had to shut down the server. This was unfortunate because the program is unable to checkpoint during the base conversion process, meaning I lost about 2 weeks worth of work.” He then lost another two weeks to a separate power outage. 😱

📜 The Epic Journey: History and Milestones of Pi Computation

grayscale photography of unknown person using computer

The quest for Pi is as old as mathematics itself. For millennia, we were stuck with just a handful of digits. The Babylonians and Egyptians had approximations that were good enough to build wonders, but they were far from precise. Archimedes of Syracuse got us a bit closer around 250 BC, but the real revolution didn’t happen until the advent of computers.

From Pen and Paper to Punch Cards

Before machines, calculating Pi was a lifetime’s work. In the 19th century, William Shanks famously calculated Pi to 707 places, a record he held for decades. The only problem? He made a mistake at the 528th digit, rendering the rest incorrect. Ouch. 😬

The computer age changed everything. In 1949, the ENIAC computer calculated 2,037 digits in just 70 hours, a task that would have taken a human years. This kicked off a computational arms race. With each new generation of hardware, from mainframes to supercomputers, the record was shattered again and again.

The Modern Era: Trillions and Beyond

The leap from thousands to millions, then billions, and now trillions of digits is a testament to Moore’s Law and the relentless innovation in computing. The 50 trillion digit calculation by Timothy Mullican in 2020 wasn’t just another number on a scoreboard; it was a landmark achievement. It demonstrated that world-record-level computation was no longer the exclusive domain of giant tech companies or government-funded labs. It could be done by a passionate expert with the right knowledge and cleverly sourced hardware. This is a huge inspiration for the DIY Electronics community we love so much.

This journey from a few digits to 50 trillion is more than a math problem; it’s a story of human curiosity and our unyielding desire to push the boundaries of what’s possible.

🔢 What Does 50 Trillion Digits of Pi Really Mean? Understanding the Scale


Video: The Pi Song (Memorize 100 Digits Of π) | SCIENCE SONGS.








So, 50 trillion. The number is so big it’s hard to wrap your head around. Let’s try to put it into a scale that makes sense.

Imagine you wanted to print out all 50 trillion digits of Pi on standard paper.

  • Assuming a standard font size (like 10-point Arial), you can fit about 5,000 digits on a single A4 page.
  • To print all 50 trillion digits, you would need 10 billion sheets of paper.
  • A standard ream of 500 sheets is about 2 inches thick. Your stack of paper would be over 31,500 miles high. That’s more than enough to reach the geostationary orbit where satellites live, and then some! 🛰️

What if you tried to read it aloud?

  • If you could recite one digit every second without ever stopping to eat, sleep, or breathe, it would take you over 1.58 million years to finish. You’d be reciting digits from the Stone Age to the present day, and you still wouldn’t be done.

The data itself, at 38 Terabytes, is immense. It’s larger than the entire print collection of the U.S. Library of Congress. It’s a digital monument to a single, infinitely long number.

🖥️ The Tech Behind the Madness: How Computers Calculate Trillions of Pi Digits


Video: New World Record! 100 Trillion digits of π.








You might think calculating Pi is as simple as telling a computer 3.14... and hitting “go.” Oh, if only! The reality is a symphony of specialized software, monstrous hardware, and brilliant algorithms. Let’s peek under the hood.

H3: The Software: y-cruncher, the Champion of Constants

The undisputed king of high-precision computation is y-cruncher. Developed by Alexander Yee, this program is a masterpiece of optimization. As Timothy Mullican noted on his blog, “y-cruncher is able to take advantage of the newest processor features and features many optimizations, which in part explains why it has been used to set several of the past Pi records.”

What makes it so special?

  • Multi-threading: It’s built to use every single core of modern CPUs, running calculations in parallel.
  • Vectorization: It uses advanced CPU instructions like AVX512 to perform the same operation on multiple numbers at once, dramatically speeding things up.
  • Swap Mode: For calculations that require more RAM than a computer has (like, you know, 50 trillion digits of Pi), y-cruncher can intelligently use hard drives or SSDs as a temporary “scratchpad.” This is crucial for home-built record attempts.

H3: The Hardware: Building a Pi-Crushing Beast

Timothy Mullican’s setup was a masterclass in sourcing powerful, second-hand enterprise gear. It wasn’t a single desktop; it was a distributed system of specialized machines.

Component Timothy Mullican’s 50T Record Setup Purpose
Computation Server HP PROLIANT DL580 Gen8 The main brain, running the y-cruncher calculations.
CPUs 4x Intel Xeon E7-4880V2 (60 cores / 120 threads total) The number-crunching muscle.
RAM 320GB DDR3 ECC The server’s short-term memory for active calculations.
Computation Storage 4x HP StorageWorks D3600 disk shelves with 48x 6TB HGST HDDs The massive “swap space” for y-cruncher, totaling over 280TB.
Output Server Dell PowerEdge R720xd A separate machine to handle the final digit output and backups.
Final Storage Dell PowerVault MD1200 with 40TB in RAID6 The permanent home for the precious 38TB of Pi digits.
Backup System HPE StoreEver MSL4048 Tape Library For creating physical backups on LTO-5 tapes, a crucial step to prevent data loss.

This isn’t your average gaming PC. This is a purpose-built data monster, and you can find similar components in our Electronic Component Reviews section.

H3: The Algorithm: The Chudnovsky Secret Sauce

Computers don’t calculate Pi by drawing a circle and measuring it. They use incredibly efficient formulas called infinite series. For decades, the go-to formula has been the Chudnovsky algorithm. Discovered by the Chudnovsky brothers in 1988, this algorithm is ferociously efficient, generating about 14 new digits of Pi for every single term added to the series. It’s the mathematical engine that makes these trillion-digit computations feasible in months instead of millennia.

💾 Storage and Data Challenges: Handling 50 Trillion Digits of Pi


Video: The Pi Song 2.0 (200 Digits of Π).








Calculating the digits is only half the battle. You also have to store them. This presents a whole new set of logistical nightmares that would make any IT admin sweat.

H3: The Data Tsunami

As we mentioned, the temporary “swap” data for the 50 trillion digit calculation peaked at 281 TB. This is where Mullican’s array of 48 hard drives came into play. The performance of this storage array was critical. He even had to upgrade his disk enclosures mid-project because the initial ones were too slow! As he detailed, “I originally used HP StorageWorks D2600 disk shelves, but I didn’t realize the SATA backplane was limited to 3Gb/s. I upgraded to the D3600 disk shelf which supports 6Gb/s SATA.” This single upgrade nearly doubled his disk speeds and shaved months off the estimated completion time.

The final output of 38 TB also needed a robust, fault-tolerant home. Mullican used a RAID 6 array, which can withstand the failure of two separate hard drives without losing any data. When the data you’re storing took 8 months to generate, you don’t take chances!

H3: When Good Computations Go Bad

What happens when the power goes out in the middle of a multi-month calculation? Catastrophe. Mullican faced this exact scenario not once, but twice. During a critical phase of the process called “base conversion,” the y-cruncher program cannot save its progress. A power loss means starting that entire phase over.

He recounts the painful experience: “As luck would have it, a transformer next to my house blew and the power went out yet again. This means I had to restart from the last checkpoint yet again, losing another 2 weeks worth of work.” In total, he lost about a month of computation time to these unforeseen events. It’s a stark reminder that even with the best hardware, the real world can throw a wrench in the works. This is why robust power backup systems (UPS) and data redundancy are non-negotiable in the world of high-performance computing.

🔍 Why Bother? The Practical Uses and Scientific Value of Ultra-Precise Pi


Video: How is pi calculated to trillions of digits?








This is the question we get all the time at Why Pi™. “Okay, it’s cool, but… why? Do we need 50 trillion digits of Pi?”

The honest answer is: no, not for practical calculations. To calculate the circumference of the entire observable universe to the accuracy of a single hydrogen atom, you only need about 40 digits of Pi.

So, what’s the point?

H3: Pushing the Limits of Computing

The primary reason is to stress-test computer hardware and software. Calculating Pi is one of the most demanding tasks you can throw at a computer. It pushes the CPU, memory, and storage systems to their absolute limits for months on end. As the y-cruncher documentation warns, “Don’t be surprised if y-cruncher exposes instabilities that other applications and stress-tests do not.”

If a computer system can survive a multi-month Pi computation, it’s proven to be incredibly stable. This is a benchmark for high-performance computing and helps drive the latest Electronics Industry News by pushing manufacturers to build more reliable components.

H3: Cryptography and the Search for Randomness

Mathematicians are fascinated by whether Pi is a “normal” number. A normal number is one in which any sequence of digits appears, on average, as frequently as any other sequence of the same length. So, the sequence “123” should appear as often as “777” or “456”.

While Pi is widely believed to be normal, it has never been proven. Calculating trillions of digits allows mathematicians to perform statistical analysis on the distribution of its digits. If Pi is truly random, its digits could serve as a source for cryptographic applications, though in practice, we use other methods to generate random numbers.

H3: The Human Element: Because It’s There

Ultimately, the quest for Pi is like climbing Mount Everest. We do it because it’s a challenge. It’s a way to plant a flag at the furthest reaches of our current technological and mathematical capabilities. It’s a beautiful, pure pursuit of knowledge driven by nothing more than human curiosity.

Beyond the hardcore computation, Pi is just plain fun. It’s full of weird and wonderful mathematical quirks.

H3: Find Your Birthday in Pi! 🎂

Because Pi is (probably) a normal number, any finite string of digits you can imagine is almost certain to appear somewhere in its sequence. This includes your birthday, your phone number, or even the entire works of Shakespeare converted to ASCII code.

Want to try it? There are websites that let you search the first few billion digits. A popular one is the Pi-Search Page. Go ahead, see if your birthday (MMDDYY) is in there!

H3: The Feynman Point

One of the most famous oddities in Pi is the Feynman Point. Starting at the 762nd decimal place, you’ll find the number 9 appearing six times in a row: ...999999.... It’s named after physicist Richard Feynman, who once joked he’d like to memorize Pi up to that point so he could recite it and end with “…nine, nine, nine, nine, nine, nine, and so on,” implying Pi was rational. It’s a classic nerd joke.

H3: Is Pi Normal? The Ultimate Unsolved Mystery

We’ve mentioned this before, but it’s the biggest open question about Pi. If Pi is normal, it means its digits are perfectly random and uniformly distributed. Every digit, 0 through 9, should appear about 10% of the time. Every two-digit pair, 00 through 99, should appear about 1% of the time, and so on, to infinity.

So far, in all 100+ trillion digits we’ve calculated, Pi appears to be normal. The digits are distributed with spooky accuracy. But in mathematics, “appears to be” isn’t good enough. We need a formal proof, and so far, no one has found one. This remains one of the great unsolved problems in number theory.

So you want to get your hands on the digits? Be careful what you wish for!

✅ You CAN search the digits: As mentioned, websites like the Pi-Search Page let you search for strings within the first few billion digits without having to download anything.

❌ You probably DON’T want to download them: Remember, the 50 trillion digit file is 38 Terabytes. Your home internet connection would likely take months to download it, and you’d need a specialized storage server to even hold the file. Even the first 100 billion digits is a massive 100 GB text file that will crash most standard text editors.

For those who are truly determined, Alexander Yee, the creator of y-cruncher, provides links to download various record-breaking computations on his website, Numberworld.org. Just make sure you have the storage space and bandwidth to handle it!
