■ Hello School 英語 (ハロ英 Ver.2) Lesson 23 関係代名詞 Part.1  ■

Hello Haromi and Manami.

 Hi, Sukuharu.
 Have you studied firmly today too?

Today I studied geography using the map of Japan.

 Do you know Inou Tadataka?

I don't know. Who is he?

 He was a person who made exactly a map of Japan in the Edo period.
 The latest map is made using artificial satellites.
 There were no such machines at that time.

How did he make the map of Japan?

 Tadataka trained to walk with a certain stride.
 That one step is exactly 69 cm.
 He calculated the distance from the number of steps.
 After he measured the distance, he checked the direction using the protractor.
 He repeatedly repeated this work.

That's great!

 And the map creation continued for the night as well.
 He observed the star such as the Polaris star, checked his position.

How long has he measured?

 For 17 years.

For 17 years! It is longer than my age.

 Effort is more important than anything else.
