摘要:
In the hope of winning a large reward offered by the British government, John Harrison set to work to construct a clock that worked at sea. Harrison's solution to the problem of time measurement at sea enabled sailors to cross the oceans of the world safely. But it was years before he was to receive the prize he had rightfully earned.
