One day two scientists were
quarrelling about whose watch was better, the German one or the Japanese one.
Since they were scientists, they decided to do an experiment to test the
watches. They went into their lab and filled a basin with water, put the watches
in, waited for 20 minutes and took them out.
They could see
there was something wrong with both watches. They observed them for several
hours before speaking to each other. They both silently found that the German
watch was losing 60 minutes and the Japanese are doubled that.
The scientist with the Japanese watch then slowly raised his head and
said, "Both watch are out of work, but my watch is right more often than yours,
so it’s better." The scientist with the German watch went home without saying a
word. |
