Ada Lovelace Ada Lovelace Augusta Ada King, Countess of Lovelace (10 December 1815 – 27 November 1852), born Augusta Ada Byron and now commonly known as Ada Lovelace, was an English mathematician and writer chiefly known for her work on Charles Babbage’s early mechanical general-purpose computer, the Analytical Engine. Her notes on the engine

next term What number should come next “ANY number can be the next term in the usually given set of terms. […] Theoretically there are many possibilities. So some understanding is essentially either implied or needed in connection with the question: What is the Next Term?” – Prof. R. C. Gupta. (“On Finding the Next Term”.) Find the next
Astrophysics The Kavli Prize The Kavli Prize is one of the highly respected prizes in science in the 21st century. It recognises scientists for their seminal advances in three research areas: Astrophysics, nanoscience and neuroscience. Consisting of a scroll, a gold medal and a cash award of 1 million $, a prize in each of
Brahmagupta The Vocabulary of Mathematical Analysis 1. Introduction The English word “vocabulary” refers to the “list of words” used in communicating one’s thought (or knowledge) to the others, and the English word “analysis” refers to the “resolution into simple elements”. Hence, according to the English dictionary, the “vocabulary of analysis” should refer to the list
Chaos On Chaos in Dynamical Systems It is well-known that in Newtonian dynamics, motion is controlled by certain differential equations along with certain initial conditions. The problem is formulated in such a manner that it becomes deterministic i.e. given the initial condition the subsequent motion is predictable i.e. there is one-one connection between time
2012 SASTRA Ramanujan Prize 2012 The SASTRA Ramanujan Prize, founded by Shanmugha Arts, Science, Technology & Research Academy (SASTRA) University in Kumbakonam, India, Srinivasa Ramanujan’s hometown, is awarded every year to a young mathematician judged to have done outstanding work in Ramanujan’s fields of interest. The age limit for the prize has been set
General Theory of Relativity Five great ‘Unsolved’ problems in Theoretical Physics Theoretical Physics, considered one of the most thrilling, exciting and pain staking branches in all of sciences, deals with explaining the mysteries of the universe in the beautiful complexities of mathematics as it has been the language of physicists from time immemorial. The brilliant minds deeply immersed in this field
Fields' Medal William P. Thurston, Theoretical Mathematician, Dies at 65 William P. Thurston, a mathematician who revolutionized understanding of the structure of three-dimensional spaces and won the Fields Medal, often described as the equivalent of the Nobel Prize for mathematics, died on Tuesday in Rochester. He was 65. Thurston’s geometrization conjecture states that compact 3-manifolds can be decomposed canonically
The Flower Puzzle The Flower Puzzle Generalized This article is a crazy generalization of the Flower puzzle by Ankush Goswami published in Gonit Sora on 12th July 2012. We now suppose that instead of three there are $$m$$ temples $$A_{1}, A_{2},dots ,A_{m }$$ and instead of doubling, the flowers increase $$n$$ times in number

Other people learn from explanations.” — Ralph Boas “An engineer thinks that his equations are an approximation to reality. A physicist thinks reality is an

103 Mathematical Constants Some Favourite Mathematical Constants Mathematical constant are really exciting and wonderful in the world of numbers. All numbers are not created equal; that certain constants appear at all and then echo throughout mathematics, in seemingly independent ways, is a source of fascination. Just as physical constants provide “boundary conditions” for the physical universe, mathematical
Clay Prize Navier-Stokes equation This is an equation which describes the motion of an incompressible fluid and is given by 1. ∂∂t ui + j=13uj∂ui∂xj = ν Δ ui – ∂p∂xi + fi (x,t) x R3, t ≥ 0, 1 ≤ i ≤ 3 2. div u = j=13∂uj∂xj = 0 x R 3 t
Birch and Swinnerton Dyer Conjecture Birch Swinnerton-Dyer conjecture This is a conjecture regarding the number of rational points in elliptic curves i.e. curves in two-dimensional plane with the equation y2 = x3 + a x + b for some whole numbers a,b. In the early 1960’s, the British mathematicians Brian Birch and Peter Swinnerton-Dyer started to use computers
Abel Prize Interview with Srinivasa Varadhan Srinivasa Varadhan, known also as Raghu to friends, was born in Chennai (previously Madras) in 1940. He completed his PhD in 1963 in the Indian Statistical Institute (ISI), Calcutta, and has been in Courant Institute of Mathematical Sciences since 1963. An internationally renowned probabilist, he was awarded the Abel Prize
Puzzles The Flower Puzzle Consider the following puzzle: There are three temples say A, B and C. A priest takes with him some flowers and visits A. The flowers instantly double itself, and the priest keeps some of those flowers in A and proceeds towards B. At B also the same thing happens, the
CERN God Particle: “If Universe is the answer what is the question…??” The whole conversation starts with Higgs Boson. If you are from non-physics background then just think it is a hypothetical sub-atomic particle with extremely negligible life span. It exists for a mere fraction of second. The specialty of Higgs boson particle is that it is considered to be the origin
2012 Pushing Back the Incomputable – Alan Turing’s Ten Big Ideas There is nothing remarkable about mathematicians’ achievements going unrecognised in a wider world changed by their discoveries. The hidden history of Alan Turing is just a particularly bizarre example — one we can expect to become much better known during the 2012 centenary of his birth. The mental check-list of things
Bonn Obituary: Prof. Friedrich Hirzebruch Friedrich Ernst Peter Hirzebruch (17 October 1927 – 27 May 2012) was a German mathematician, working in the fields of topology, complex manifolds and algebraic geometry, and a leading figure in his generation. He has been described as “the most important mathematician in the Germany of the postwar period.” We at
Alan Turing Turing’s Mathematical Theory of Morphogenesis One of the fascinating aspects of the natural world is the diversity of shapes that make up the animal and plant kingdoms: the intricate patterns on a sunflower, the dramatic antlers on a stag, animal coat markings. The list is endless. How these patterns arise is one of the mysteries
