Mamikon Mnatsakanian Mamikon A. Mnatsakanian (Armenian: Մամիկոն Մնացականյան) is Project Associate at Project Mathematics! at the California Institute of Technology. He received a Ph.D. in physics in 1969 from Yerevan State University, where he became professor of astrophysics. As an undergraduate he specialized in the development of geometric methods for solving calculus problems by a visual approach that makes no use of formulas, which he later developed into his system of visual calculus. In 2010 he was nominated by Caltech for the Ambartsumians International Prize, awarded annually by the President of Armenia, for his contributions in the field of theoretical astrophysics.[1] In 1959 he discovered a new proof of the Pythagorean theorem.[2] See also[edit]Generalized conic Visual calculusReferences[edit]^ Visual Calculus and Theoretical Astrophysics ^ "Mamikon's Proof of the Pythagorean Theorem" [...More...]  "Mamikon Mnatsakanian" on: Wikipedia Yahoo

Pythagorean Theorem In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. The theorem can be written as an equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation":[1] a 2 + b 2 = c 2 , displaystyle a^ 2 +b^ 2 =c^ 2 , where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides. Although it is often argued that knowledge of the theorem predates him,[2][3] the theorem is named after the ancient Greek mathematician Pythagoras Pythagoras (c [...More...]  "Pythagorean Theorem" on: Wikipedia Yahoo 

Theoretical Astrophysics Astrophysics is the branch of astronomy that employs the principles of physics and chemistry "to ascertain the nature of the astronomical objects, rather than their positions or motions in space."[1][2] Among the objects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background.[3][4] Their emissions are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition [...More...]  "Theoretical Astrophysics" on: Wikipedia Yahoo 

President Of Armenia The president is a common title for the head of state in most republics. In politics, president is a title given to leaders of republican states. The functions exercised by a president vary according to the form of government. In parliamentary and semipresidential republics, they are limited to those of the head of state, and are thus largely ceremonial. In presidential republics, the role of the president is more prominent, encompassing also (in most cases) the functions of the head of government [...More...]  "President Of Armenia" on: Wikipedia Yahoo
