I am amazed at the versatility of mathematics as a tool, where art is concerned. Mathematics can be the subject of art, or it can be used in the process of creating art. Sometimes both happen at the same time. I like to experiment, and I have used pencil, pen, pastel, acrylic, paper, cardboard, scanners, cameras, computers, printers, metals, and wood in creating mathematical artwork. Sometimes the mathematics in art can be complex, sometimes it can be simple. This year, my entry is intentionally very simple.
DA DA coins
20 x 20 x 10 cm
The DA DA coins are sequels to my DA DA dice (JMM 2016). Simplicity is the idea again, to the point of absurdity.
We can call it lowbrow mathart.
Both coins come from a maple tree that used to live in my yard. Each coin has the word "DA" burned onto both sides. The outcome of a toss of the DA DA coins is a discrete random variable X with singleton sample space DADA. The probability of DADA is p(DADA)=1.
