10th Honinbo
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

9th Honinbo
9 (nine) is the natural number following and preceding . Evolution of the Arabic digit In the beginning, various Indians wrote a digit 9 similar in shape to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a -look-alike. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic. While the shape of the glyph for the digit 9 has an ascender in most modern typefaces, in typefaces with text figures the character usually has a descender, as, for example, in . The mod ...

Evolution of the Arabic digit In the beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted.

The eastern Arabs developed the digit f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eio Sakata
was a 9-dan Japanese professional Go player. Biography Sakata became a professional Go player in 1935. His first title match was the Hon'inbō in 1951 when he challenged Hashimoto Utaro. More than usual was at stake in the match because Hashimoto played for the Kansai Ki-in, which Hashimoto had founded the year before. This put additional pressure on Sakata to win the title back for the Nihon Ki-in. Sakata started out well, winning three of the first four games, but Hashimoto fought back and won the final four games, and so kept the Hon'inbō title. Afterwards, Sakata went on to win a couple of small titles which were the start of a meteoric run of major wins in which he won almost all of the titles in Japan except the Hon'inbō. In 1961 he was once again the challenger for the Hon'inbō. His opponent, Takagawa Kaku, had held the title for nine years straight. Sakata won the Hon'inbō and held it for seven years in a row. Thus he became an honorary Honinbo, and was later cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
