Pi is a mathematical constant representing the ratio of a circle’s circumference to its diameter, approximately equal to 3.14159. It is an irrational number, meaning it cannot be expressed exactly as a fraction, and its decimal expansion goes on forever without repeating. Pi appears in countless formulas across mathematics and physics, from calculating areas and volumes of circular shapes to describing wave patterns and the behavior of pendulums. Despite its simple definition, pi holds deep sign

Today is of course Pi Day and the International Day of Mathematics. 不 Helping us celebrate are CSIRO’s Data61 researchers, Petra Kuhnert and Cheng Soon. Both Petra and Cheng are using mathematics across different machine learning, artificial intelligence and data science applications. #IDM314 | CSIRO | Facebook
