2010年3月14日：圆周率日。

Mathematics enthusiasts will this weekend be celebrating Pi day, which falls on 14 March in honour of the famous ratio's first few digits, 3.14.

数学迷们将在本周末庆祝他们的圆周率日，这一天之所以落到3月14号是为了纪念这个这个著名比例的头几位：3.14。

The first Pi Day celebrations were held at the San Francisco Exploratorium when the now retired Larry Shaw decided the day was worth commemorating.

第一届pai节的庆祝活动是在旧金山的探索博物馆里举行，现已退休的Larry Shaw那时就觉得这个日子值得纪念。

He said this one day last fall after accurately reciting PI to 100, 000 decimal places. It took him 16 hours.

去年秋天他说这句话的时候刚刚花费16个小时背诵到小数点后10万位。

One day, Tsau Pi called Tsau Jr into see him. He ordered his brother to make up a poem within the time it took to walk seven steps, adding that if he could not, his life would be in danger.

有一天，曹丕要求接见曹植，他要求曹植在他七步之内作诗一首，如果做不到，就会有生命危险。
