Pi

A Brief History of Pi

So, back in the ancient world, the Egyptians were building the Great Pyramids of Giza. In this case, Pi is calculated to a precision of 3 digits, 3.142857, with 142857 repeating after the whole number value, 3.

This is odd. Consider the Legend of the Seven Sisters (i.e., the Big Dipper, Messier 45): according to astronomers, this legend is approximately 100,000 years old (link).

Now, the early Christians calculated the total lifespan of the world to 7,000 years (link). So, I am presented with 2 numbers, 100,000 and 7,000. Since I like to tinker with numbers, and I remembered the verse, Luke 12:51 (link), I decided to test Jesus of Nazareth's purpose and divide the larger value by the smaller value. 100,000 / 7,000 = 14.2871...repeating with 142857 after the initial 6 digit sequence. The strangeness is this: Egypt's Giza pyramid calculation is 22 / 7. 22 / 7 = 3.142857...repeating with 142857 after the initial whole number value, 3. 

This is strange, indeed. 

So, we can say Pi is usable with accuracy dependent on a time basis. The more contemporary example of Pi usage is NASA, if they want to get a rocket ship into orbit, they usually just require 15 digits of Pi: 3.14159265358979 (link). But I do not believe this is a correct usage of Pi. For example, consider a single helix.

Now, think about a DNA molecule. For it is shaped as a double helix.

Taken from Wikipedia,

For example, we have permutations in genetic structure. So, hypothetically speaking, we should be able to find a specific section of a DNA lifecycle using Pi. For this is just a matter of finding a fraction of Pi. But if we can identify sections of DNA using Pi, we should be able to better identify abnormalities in this genetic structure. Consider Aristotle's scriptures on forms, if the form is imperfect, we might be looking at a health condition like a genetic disease.

In C, Calculating Pi

In this section I shall share this: against Dik T. Winter's Pi Computing in C, my experience. Regarding this, here is my Repl.it repository: link. Just click Run. On Repl.it, you, reader, can compile certain programming languages, and run them, online. With a GitHub account, you can also import your own GitHub repositories. But I do not feel this is an adequeate Pi solution. Against Winter's work is his whole-number-producing app, Pi Computing in C; it does not produce Pi, a decimal. 

Instead, it is producing an 800-digit number that is a number sequence, but no decimal separated the 3 from the following digits, so there is no similitude. If you, reader, want to play with this code, I figure you can get near 80000 digits with it, scaling the array, and 2800 for loop limits by powers of 10, but 800000 might be too much for something built more than 6 years ago. I used my Surface Pro LTE and got a segmentation fault at 2800000 array elements because that requires a huge amount of cache memory. In the future, I shall attempt modifying this code, and run it using MPI or GPGPU.

Raspberry Pi 4

On technology applications of the mathematical constant, Pi, a Welsh-born University of Cambridge Computer Scientist, former ASIC architect of Broadcom, and entrepreneur, Dr. Eben Upton, invented an affordable computer on a chip in 2006.

Pi Machin

From Ken Ward's JavaScript tutorial (link), I got this free app. This is a Machin Pi calculator. My calculating device, a Microsoft Surface Pro 5 LTE, gave 100005 digits: in 135.26 seconds. From years ago, this is a much faster result time than Ken Ward's rig. On Google Chrome, Chrome may display a Page Unresponsive prompt. Press "Wait" or "Exit Page." Google Chrome complained more than twice. For digit confirmations, use Pi Search (link). Number of Digits (the output is the input plus 5): Number of Digits:
