Description: A black background displays white text listing mathematical formulas and their descriptions. It starts with the Pythagorean Theorem (a² + b² = c²), followed by the Area of a Circle (Area = πr²), and the Circumference of a Circle (C = 2πr). It concludes with 'AND FINALLY... THE BIG ONE' and the equation for a line (y = mx + b) described as '(A FREAKIN' LINE)'.

Description: Rendered on a deep dark background, this artwork presents a circle with its diameter of 20,000 and circumference of 62,832, ringed by petals, above Aryabhata's approximation π ≈ 62,832 / 20,000 = 3.1416. In his Aryabhatiya of 499 AD, the Indian mathematician and astronomer Aryabhata gave the value of pi as 62,832 divided by 20,000, or 3.1416, an exceptional precision for his time. Made for math teachers, mathematicians and students who love an elegant proof, it brings classic mathematics to a classroom, study or home office.
