Caption: Bahman Kalantari, American-Iranian computer scientist and mathematician. Kalantari, an associate professor at Rutgers University, USA, has written software that visualises polynomial equations into colourful graphics (on computer screen and in the picture frames). These visualisations are known as polynomiography. Polynomials are algebraic equations of constants and variables that can be subtracted, added, multiplied and raised to a non-negative power. An example of a polynomial would be 4x(/\2)+3x-7, where x is a variable, 7 is a constant, 4 and 3 are coefficients (combination of both number and variable) and /\ indicates the exponent. Polynomiographs have been used to assist school students learning algebra and exhibited in galleries.
