On a sunny afternoon in San Francisco, I stumbled upon this intriguing art piece embedded in the city's pavement. The plaque, a circular tribute to the mathematical constant pi (π), adds a curious touch to the otherwise ordinary tarmac. Its design features the digits of pi spiraling inward, inviting passersby to pause and appreciate the intersection of art and mathematics. Captured on August 9, 2025, this hidden gem reflects how creativity and numbers can transform an urban setting into an open-air gallery.
