二十年研究，就为了证明所有游泳池里都被撒过尿。
二十年，一半的职业生涯，就为了这个，看来玉米地太无聊了。
It’s a hard truth, but after 20 years studying swimming pool chemistry,
Ernest Blatchley III, an environmental engineer at Purdue University, is
willing to tell it like it is: People pee in swimming pools.
“It’s fair to assume that any pool that has people in it, also has urine
in it,” Blatchley says. “What we have found is the average swimmer leaves
about roughly the equivalent of a shot glass (1 to 2 ounces) of urine in the
pool.”
Blatchley says he’s never studied a pool that didn’t have urine in it. | d****o

再者，他不可能采样世界上所有的泳池，最多通过他的样本数量给出个所有泳池都有尿
的概率而已
结论：文科生

发帖数: 43471 | 4 美帝的理科生也一个水平，我老遇过非要我证明30tb数据bit to bit一样的，我老随机
做了1%的取样，他坚持认为不能证明，我老问那你以后是不是每套数据都要这么做，他
又说就这个做好就行。
