Hello my name is Hiroto Tanigwa. And today I would like to talk about Torricelli and his work finding the atmospheric pressure.
It was known that well which depth is over 10 meters can not be pumped water directly. but people do not know why occur this phenomenon. Because there was not the concept of atmospheric pressure. In 1643, Torricelli experimented and proved the existence of atmospheric pressure.
research question 
does atmospheric pressure exist ?

Hi, your writing is very good!  There are just a couple mistakes, mainly with sentence structure:

well which depth is over 10 meters can not be pumped water directly (the structure is a little confusing - maybe you want to write: It was known that water cannot be pumped directly from a well which has a depth of over 10 meters.

, but people did not know why this phenomenon occurred because there was not the concept of atmospheric pressure.

Best wishes!
