圆周率日

今天，我们用这张绝美无比的灌木丛迷宫鸟瞰图来庆祝圆周率日，该迷宫位于塞浦路斯的阿伊纳帕植物园。圆周率日的意义在于纪念数学常数π。如果用计算器求圆周率的值，它可能会被截止到小数点后15位或更少，但在数学中π被认为是一个无限的比值。阿伊纳帕植物园灌木丛迷宫的圆形图案把圆周率公式带入了现实，这里也是长途步行爱好者的必游之地。如果你准备好迎接挑战，那就来这个巨型迷宫试试吧。

Pi Day

Today we're celebrating Pi Day with this magnificent bird's-eye image of the maze of bushes at Cyherbia Botanical Park in Ayia Napa, Cyprus. The significance of this day is to remember the mathematical constant Pi. If you use a calculator to find the value of Pi, it may truncate at 15 decimal digits or less, but in mathematics it is considered a never-ending ratio. The circular pattern of the labyrinth at the Cyherbia Botanical Park brings this equation to life and is a must-visit for people who love long walks. If you're ready for a challenge, give this large hedge maze a go.
