Today is the birthday of Srinivasa Ramanujan , the great Indian mathematician who studied number theory, mastered modular and partition functions, and designed summation formulas. Ramanujan was born on December 22, 1887 in Erode, a city along the banks of the Cauvery River in the southern state of Tamil Nadu . He enrolled in a local high at the age of 10, but learned more about mathematics from the college students who boarded in parents' home. According to Robert Kanigel, Ramanujan's biographer and author of The Man Who Knew Infinity , the young mathematician was deeply influenced by two borrowed books: S.L. Loney's Plane Trigonometry and George Shoobridge Carr's Synopsis of Elementary Results in Pure Mathematics . Carr's work, a list of 5000 mathematical formulas, inspired Ramanujan to develop his own proofs for these theorems. By the age of 17, Ramanujan had calculated Euler's constant to 15 decimal places and proposed a new class of numbers. Although his p...

PLATONIC SOLIDS AND THEIR NETS

Definition REGULAR POLYHEDRA: A 3-dimensional object bounded by regular polygons. Can you guess how many regular polyhedra exist? SURPRISINGLY…. There are only FIVE regular solids composed of just 3 regular polygons: the triangle, square and pentagon. The five regular polyhedrons are Tetrahedron, Cube, Octahedron, Icosahedron and Dodecahedron. Also, if you combine 2 regular polygons triangle with square, pentagon with triangle and so on, you can make other polyhedra. There are 13 such more solids known as “Archimedian Solids”.
