This right there is an anomaly, as 22\/7 is a more accurate approximation of Pi than is 3.14. We mathematicians can live with using the MM\/DD date format as that is the only way we have a sniff at having a Pi-Day; but calling the more accurate number as the approximation day is a bit rich.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\u2026..??? ???? ????????<\/h2>\n\n\n\n<p>The Babylonians had a stab at it as early as 2000 BC coming as close as 3.125 or 25\/8. Archimedes provided a breakthrough by inscribing and circumscribing polygons about a circle and generating lower and upper bounds. Our own Ramanujan developed some juicy methods that were later incorporated into computer algorithms. Inevitably, machines entered the fray and we have apparently now computed up to 2.17 trillion digits. The beauty about the 2.7 trillion-digit approximation is that from 2000 BC to 2100 AD we have moved by 0.5% &#8211; those Babylonians must have been pretty cool then, huh.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a href=\"https:\/\/online.2iim.com\/cat-exam-preparation-online-cat-coaching.shtml\" target=\"_blank\" rel=\"noreferrer noopener\">??? ???????????<\/a> ???????? ??<\/h2>\n\n\n\n<p>When we are young we are told that Pi equals 22\/7, we feel good about ourselves and solve a bunch of problems with it. Then after a while we realize that Pi is not really 22\/7 and has many more layers to it; on top of it the damn thing is irrational. Kinda like CAT-based selection process. Like CAT preparation itself, it appears to be endless. But don\u2019t let the shoulders drop, like PI itself CAT preparation is useful in a variety of contexts, is delightfully fascinating and is most definitely not pointless. \ud83d\ude00<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"721\" height=\"600\" src=\"https:\/\/i0.wp.com\/online.2iim.com\/cat-exam\/blogs\/wp-content\/uploads\/2021\/07\/2020-07-21.png?resize=721%2C600&#038;ssl=1\" alt=\"Dunning-Krugger effect!\" class=\"wp-image-13910\" srcset=\"https:\/\/i0.wp.com\/online.2iim.com\/cat-exam\/blogs\/wp-content\/uploads\/2021\/07\/2020-07-21.png?w=721&amp;ssl=1 721w, https:\/\/i0.wp.com\/online.2iim.com\/cat-exam\/blogs\/wp-content\/uploads\/2021\/07\/2020-07-21.png?resize=300%2C250&amp;ssl=1 300w\" sizes=\"(max-width: 721px) 100vw, 721px\" data-recalc-dims=\"1\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">?????? ??????<\/h2>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"500\" height=\"277\" src=\"https:\/\/i0.wp.com\/online.2iim.com\/cat-exam\/blogs\/wp-content\/uploads\/2021\/07\/Hakuna-Matata.gif?resize=500%2C277&#038;ssl=1\" alt=\"Hakuna Matata!\" class=\"wp-image-13911\" data-recalc-dims=\"1\"\/><\/figure><\/div>\n\n\n\n<p>No discussion on Pi ends without a reference to the Circle of Life and a call-out to the utterly delightful phrase \u2018Hakuna Matata\u2019.
