Khayyam-Pascal, Punctum Caecum series, 2015

In Khayyam-Pascal installation, 2015-2016, I screen-printed layers of mathematical diagrams and binomial coefficient (numbers), Khayyam’s mathematics manuscript page and Sierpiński’s triangle patterns on 160-360 hand-cut felt triangles. The pyramid pattern of the installation resembles Pascal Triangle. In mathematics Pascal triangle is a triangular array of the binomial coefficients. It is named after the 17th century French mathematician, Blaise Pascal. However, the 12th century Iranian mathematician, Khayyam, had studied it centuries before Pascal. Through this installation I pay homage to both mathematicians.

Research

Blaise Pascal’s version of the triangle                                                                Rows zero to five of Pascal’s triangle

“At around the same time, it was discussed in Persia (Iran) by the Persian mathematician. It was later repeated by the Persian poet-astronomer-mathematician Omar Khayyám (1048–1131); thus the triangle is referred to as the Khayyam-Pascal triangle or Khayyam triangle in Iran”

The pattern obtained by coloring only the odd numbers in Pascal’s triangle closely resembles the fractal called the Sierpinski triangle

Khayyam-Pascal as part of Punctum Caecum series has been exhibited in a solo exhibition in March 3-25, 2016 at California State University, Stanislaus, Turlock, CA and in a group exhibition in InSpace Curatorial Gallery in SF, CA in November-December, 2015
