Traditional
Japanese Geometry.
SANGAKU.
In 17 century, the Traditional Japanese
Mathematics started and developed all over Japan.
From 17th century to 20th century, many Japanese
people enjoyed traditional Japanese mathematics.
Some of them wanted to display his ability to the
other people and they dedicated wooden tablets
to shrines and temples on which mathematics
problems were drawn.
This tablet is called as SANGAKU.
SAN and GAKU implies
Mathematics and Tablet,
respectively.
Now, about 900 SANGAKU
have survived.
.
.
Japanese Temple Geometry,
Sangaku is an interesting world
of mathematics and art.
This world developed by
ordinary people, including
mathematicians, who were love
th
in mathematics, in 17 century
to 20th century of Japan.
“Enjoy” is very important in
mathematics.
This world is useful in
mathematics education,
I believe.
Many thanks for my talk.
