Everyone should be interested in Pi this summer

Now, with summer in full swing, you’ll likely find yourself at a family barbecue, picnic, or outdoor celebration. And with every good summer outing comes a great summer dessert. Sometimes this is popsicles, sodas, or even fresh berries for the more health conscious. But mostly, it’s pie.

However, a more important pancake – perhaps The Most important – it is actually you can not eat it at all.

and that with me. or 3.14.

It is referred to once in medieval Latin Described in a very literal and simple way, “the quantity, which when the diameter is multiplied by it, produces the circumference,” Pi is one of the most fascinating numbers in all of mathematics and a delicious accompaniment to any summer conversation.

In its simplest form, pi is Rate From the diameter of the circle to its circumference. The fact that you can take any circuit from the small head of a pin to a UY Scuti – The largest known star in the universe – Divide the distance by the distance around it, and get the same number (pi), this is mind-boggling in itself.

But, why would someone want to find this ratio? Well, think back to high school engineering. Often you need the ratio to determine the dimensions of any shape.

However, the benefit of pi goes beyond circles and domains. It is of great importance to compute countless mathematical equations and is widely used in engineering, astronomy and architecture, and even plays a role in Discrediting the work of the investigator in the OJ Simpson trial.

This is the numerical constant that the Babylonians said It was first estimated nearly 4,000 years ago to three decimal placesnow counted to more than 100 trillion numbers By a supercomputer, and it’s still going on as we’re talking. Since pi is an irrational number (a decimal number that lasts forever and never repeats), the arithmetic power of a supercomputer can grow exponentially, and we will never be able to know all of its numbers.

A review of the history of the concept of pi is a glimpse into the astonishing achievements and broader intellectual development of earlier civilizations. Shortly after the Babylonians used 3.125 to calculate the area of ​​a circle by multiplying it by the square of its radius, the ancient Egyptians rounded up the same constant at 3.1605, Documented in the famous Rhine Papyrus. In fact, according to RealityMany Egyptologists believe that the Egyptians intentionally made the ratio of the height of the Giza pyramid to its base identical to the ratio of a circle’s diameter to its circumference (that is, pi!).

We did not have evidence of a more detailed account until more than a thousand years later when the Greek mathematician Archimedes declared, I tried to find The area of ​​a circle using the Pythagorean theorem. Without going into too much detail, Archimedes show up That pi is between 3 1/7 and 3 10/71. He knew he hadn’t found the exact number, but this was an exceptionally rough estimate. More detailed work using Archimedes’ approach was done over 2000 years, with Johann Heinrich fix In 1767, that pi is irrational and therefore completely unknowable.

Although the hard work of calculating pi from scratch is no longer necessary due to the advent of computers, the number itself has developed a tracking cult in modern times. Pi Day, March 14 (3/14) Recognized and celebrated all over the world. People celebrate the pie and hold digital recitation competitions. The The current official world record is 70,030, followed by Suresh Kumar Sharma in 2015.

So, this summer, when you find yourself enjoying a nice bite of rhubarb or apple pie, remember to let go of that last letter, and think of its more important cousin.
