A Quartically Convergent Square Root Algorithm: an Exercise in Forensic Paleo-Mathematics
A Quartically Convergent Square Root Algorithm: An Exercise in Forensic Paleo-Mathematics David H Bailey, Lawrence Berkeley National Lab, USA DHB’s website: http://crd.lbl.gov/~dhbailey! Collaborator: Jonathan M. Borwein, University of Newcastle, Australia 1 A quartically convergent algorithm for Pi: Jon and Peter Borwein’s first “big” result In 1985, Jonathan and Peter Borwein published a “quartically convergent” algorithm for π. “Quartically convergent” means that each iteration approximately quadruples the number of correct digits (provided all iterations are performed with full precision): Set a0 = 6 - sqrt[2], and y0 = sqrt[2] - 1. Then iterate: 1 (1 y4)1/4 y = − − k k+1 1+(1 y4)1/4 − k a = a (1 + y )4 22k+3y (1 + y + y2 ) k+1 k k+1 − k+1 k+1 k+1 Then ak, converge quartically to 1/π. This algorithm, together with the Salamin-Brent scheme, has been employed in numerous computations of π. Both this and the Salamin-Brent scheme are based on the arithmetic-geometric mean and some ideas due to Gauss, but evidently he (nor anyone else until 1976) ever saw the connection to computation. Perhaps no one in the pre-computer age was accustomed to an “iterative” algorithm? Ref: J. M. Borwein and P. B. Borwein, Pi and the AGM: A Study in Analytic Number Theory and Computational Complexity}, John Wiley, New York, 1987. 2 A quartically convergent algorithm for square roots I have found a quartically convergent algorithm for square roots in a little-known manuscript: · To compute the square root of q, let x0 be the initial approximation. -

Role of Vedic Mathematics in Driving Optimal Solutions for Real Life Problems
ROLE OF VEDIC MATHEMATICS IN DRIVING OPTIMAL SOLUTIONS FOR REAL LIFE PROBLEMS Deepshikha Bhargava1, Anita Arya2 1,2AIIT, Department Amity University Rajasthan (India) ABSTRACT In this paper, we show the importance of Vedic mathematics to derive the optimal solution for real life problems. Vedic Mathematics is the name given to the ancient system of Mathematics which was rediscovered from the Vedas between 1911 and 1918 by Sri Bharati Krsna Tirthaji (1884-1960). According to his research all of mathematics is based on sixteen Sutras or word-formulae. It is not only useful for arithmetic computations but also helpful for solving problems related to other branches of Mathematics as Algebra, Trigonometry and Calculus etc. Vedic mathematics not only helps in faster computations but also in determining the right solutions to a problem. Keywords: Algebra, Arithmetic, Calculus, Sutra, and Vedas. I. INTRODUCTION Vedic Mathematics is the name given to the ancient system of Mathematics which was rediscovered from the Vedas between 1911 and 1918 by Sri Bharati Krisna Tirthraji (1884-1960). According to his research all of mathematics is based on sixteen Sutras or word-formulae. For example, 'Vertically and crosswise` is one of these Sutras. These formulae describe the way the mind naturally works and are therefore a great help in directing the student to the appropriate method of solution. Instead of learning by repetition, vedic mathematics involves logic and understanding the fundamental concepts. One can do calculations much faster than done by using the conventional method that is taught in schools. It teaches the students the same problem in different ways. -

Some Interesting Facts, Myths and History of Mathematics
International Journal of Mathematics and Statistics Invention (IJMSI) E-ISSN: 2321 – 4767 P-ISSN: 2321 - 4759 www.ijmsi.org Volume 4 Issue 6 || August. 2016 || PP-54-68 Some Interesting Facts, Myths and History of Mathematics Singh Prashant1 1(Department of Computer Science, Institute of Science, Banaras Hindu University) ABSTRACT : This paper deals with primary concepts and fallacies of mathematics which many a times students and even teachers ignore. Also this paper comprises of history of mathematical symbols, notations and methods of calculating time. I have also included some ancient techniques of solving mathematical real time problems. This paper is a confluence of various traditional mathematical techniques and their implementation in modern mathematics. I. INTRODUCTION I have heard my father saying that ―Mathematics is the only genuine subject as it does not change with boundary of countries‖. It is lucrative just because of its simplicity. Galileo once said, ―Mathematics is the language with which God wrote the Universe.‖ He was precise in calling mathematics a language, because like any dialect, mathematics has its own rubrics, formulas, and nuances. In precise, the symbols used in mathematics are quite unique to its field and are profoundly engrained in history. The following will give an ephemeral history of some of the greatest well-known symbols employed by mathematics. Categorized by discipline within the subject, each section has its own interesting subculture surrounding it. Arithmetic is the most rudimentary part of mathematics and covers addition, subtraction, multiplication, and the division of numbers. One category of numbers are the integers, -n,…-3,-2,-1,0,1,2,3,…n , where we say that n is in .The capital letter Z is written to represent integers and comes from the German word, Zahlen, meaning numbers. -
Introduction to History of Architecture in India Professor Dr Pushkar Sohoni Indian Institute of Science Education & Researc
Introduction to History of Architecture in India Professor Dr Pushkar Sohoni Indian Institute of Science Education & Research, Pune National Programme on Technology Enhanced Learning Humanities and Social Sciences, IISER Pune Early Architecture Today we will look at early architecture in India starting with the bronze age going right up to the decline of Buddhism in India. (Refer Slide Time: 0:27) The Indus valley civilization which is considered to be in the middle of the bronze age in the north west corner of an undivided India was followed by a vedic culture because of people who moved in from the cockus mountains in Europe. In south india simultaneously we have megaliths all of these developments will be followed by kingdoms in central and North India the birth of the Buddha. And of mahaveera the rise of the mauryas with emperor Ashok expanding the mauryan kingdom and then the beginning of temple Hinduism in the mean time Buddhist cave sides will have chaityas and also Viharas and we start getting somewhere around the second third fourth century CE free standing temples the first one being temple 17 at sanchi. (Refer Slide Time: 1:32) But to begin with we have to start with the Indus valley a civilization which is divided into 3 even phases early mature and late the Indus valley is characterised. (Refer Slide Time: 1:47) By a uniformity of majors and standards that you find across a very large area they construct big urban centers in bricks the bricks are of uniform measurements most of the layouts are grid ion which use to say streets early at right angles to each other and you have very sophisticated systems of drainage and sewage in all the cities of demanders.
