Today, I went to Seoul museum of history.
In there, I learned many things. But I think water clock is the best memory. Because I want to be a scientist.
Great scientist of Joseon Dynasty, 장영실 invented water clock, Jagyeoknu.
Before 장영실 invented water clock, people could not tell the time even on cloudy days and at night.
But after 장영실 invented water clock, people could tell the time even on cloudy days and at night.
I want be a scientist like 장영실.
Because I want to be a needs to everyone!! |
