Sangaku, How to Calculate Math Japanese tradition

Sangaku, How to Calculate Math Japanese tradition:
Speaking of math, Japan has its own traditions that are not affected by the development of mathematics in Arab or Western.

So when the Arab world gave birth to Musa al-Khwarizmi, and the emergence of scientists at the West Sir Isaac Newton, Gottfried Wilhelm Leibniz, and others around the 17th century, Japan has a way of answering questions about complex geometries.



As a nation known religious, mathematical Japan into works of art in the form of carved wooden tablets called Sangaku and so decorate the walls of a Shinto shrine or Buddhist. Widely used as an offering to the gods in the Edo period, the beginning of the 17th century until 1857.

"Tablet Sangaku perhaps the most unique among the world's cultural creations. He is at once the object of art, reliji offerings, and notes can be referred to as the math people," said Tony Rothman of the University of Princeton.

He added Sangaku is a viable cultural heritage preserved and protected. "It's probably just a crossword puzzle version of feudal Japan era, but its function keep their minds sharp."
The purpose of Sangaku there are three: show off math achievement, a sense of gratitude to the Buddha and Gods, and offerings that they awarded more mathematical knowledge.


Forgotten and Preservation

When Japan began to open up, Sangaku almost forgotten. In fact, Fukugawa, high school teacher in Japan has a doctorate in mathematics admitted, before he thought studying ancient tablets Sangaku is futile.

"Until one day when my partner, a historian for help translating a book on the subject. Was not until I realized mathematicians solve problems Edo been difficult without the tools we have today," he said. "Since then I fell in love with Sangaku." He wanted to keep the existence of ancestral relics that.

Grandfather of 63 years of research helped Rothman. Though the two are separated thousands of miles and never face to face. Fortunately, mathematics is a universal language.

In addition to the research involved, Fukugawa admitted Sangaku always looking for ways to teach his students. But be careful not to cause problems precisely the new math. Therefore, "it must be remembered that Sangaku created and displayed primarily for pleasure."

As well as a number of people in the hobby that makes Japanese poetry or haiku and other arts. "There are some people enjoy math, and see something beautiful in it."

Math is entrenched, a tradition of Sakura. So no wonder that Sudoku is played people today, first popular in Japan before spreading across the ocean to the world.
