Babylonians<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The earliest known approximation of pi dates back to ancient times. The ancient Egyptians used a method of &#8220;squaring the circle&#8221; to estimate pi at around 3.125. Similarly, the ancient Babylonians calculated pi by using a formula that provided an approximation of 3.125 as well.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Archimedes_and_polygons\"><\/span>Archimedes and polygons<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One of the significant breakthroughs in approximating pi was made by the Greek mathematician Archimedes around 250 BCE. Archimedes inscribed and circumscribed polygons around a circle, progressively increasing the number of sides. By doing so, he narrowed down the possible range of pi and obtained an approximation between 3.1408 and 3.1429.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Madhava-Leibniz_series\"><\/span>The Madhava-Leibniz series<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In the 14th century, the Kerala school of mathematics, led by Indian mathematician Madhava of Sangamagrama, derived an infinite series for calculating pi. The series, which resembles the later discovered Leibniz formula, converges to the value of pi. This method provided a new approach to calculating pi with increasing accuracy.<\/p>\n<p>**<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_discovery_of_calculus_and_the_Basel_problem\"><\/span>The discovery of calculus and the Basel problem<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>**<\/p>\n<p>The discovery of calculus in the 17th century opened new avenues for approximating pi. The Swiss mathematician Leonhard Euler revolutionized the study of pi by connecting it to the Basel problem. The Basel problem sought to find the sum of the reciprocals of the squares of positive integers. Euler showed that the sum of these reciprocals was equal to pi squared divided by 6, allowing for better approximations of pi.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Computers_and_the_Bailey%E2%80%93Borwein%E2%80%93Plouffe_formula\"><\/span>Computers and the Bailey\u2013Borwein\u2013Plouffe formula<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>With the advent of computers, mathematicians could explore even more sophisticated methods for approximating pi. In 1995, mathematicians David Bailey, Peter Borwein, and Simon Plouffe discovered the Bailey\u2013Borwein\u2013Plouffe formula. This formula utilizes the hexadecimal representation of pi and allows for the calculation of its individual digits, making it one of the fastest algorithms for computing pi.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Modern_methods_and_supercomputers\"><\/span>Modern methods and supercomputers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Today, mathematicians continue to develop new algorithms and methods to obtain increasingly accurate values of pi. Supercomputers play a crucial role in these calculations, capable of performing trillions of calculations per second. These advanced techniques have allowed for the calculation of pi to billions, trillions, and even quadrillions of decimal places.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"FAQs\"><\/span>\n<h3>FAQs:<\/h3>\n<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>**<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Q1_What_is_the_current_value_of_pi\"><\/span>Q1: What is the current value of pi?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>**<br \/>\nThe value of pi is an irrational number and is commonly rounded to 3.14159.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Q2_Can_pi_be_calculated_exactly\"><\/span>Q2: Can pi be calculated exactly?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>\nNo, pi is an irrational number, meaning it cannot be expressed as a simple fraction, and its decimal representation goes on forever without repeating.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Q3_How_many_decimal_places_of_pi_have_been_calculated\"><\/span>Q3: How many decimal places of pi have been calculated?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>\nAs of 2021, pi has been calculated to over 50 trillion decimal places.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Q4_How_is_pi_used_in_real-life_applications\"><\/span>Q4: How is pi used in real-life applications?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>\nPi is used extensively in mathematics, physics, engineering, and various scientific calculations.
