History of binary system. In , he first realized that two digits—0 and 1—are all that are really needed for a positional number system. Binary arithmetic could handle any problem decimal arithmetic could deal with. At this point, Leibniz hadn't seen the I Ching. The I Ching is a system where coins are used to randomly generate.

History of binary system. If you have spent any time around computers, you have probably heard of the binary number system. But what is it, exactly, and why is it so.

History of binary system


What is the origin of binary numbers? Is it true That Leibniz came up with binary numbers upon studying the I ching, which supposedly originated from a fish man in china named FUXI?

There is of course nothing special about the decimal number system with its ten digits. The ancient Babylonians and Sumerians used a base 60 system as early as the 19 th century B. Europeans learned decimal numbers and arithmetic from the Arab world, which in turn learned it from India.

Various theories have India inventing the numbers, or learning it from the Chinese or Babylonians via the Greeks. In any case, the decimal numbers were widely used in Europe by the time of the Renaissance, and by that time no one questioned the use of a base 10 system. No one, that is, until Leibniz came along. Binary arithmetic could handle any problem decimal arithmetic could deal with.

At this point, Leibniz hadn't seen the I Ching. The I Ching is a system where coins are used to randomly generate hexagrams, a group of six lines where each line represents either "yin" or "yang". Therefore, each hexagram can be thought of as a six digit number in the binary system. This site indicates that roughly ten years later, Leibniz was introduced to the I Ching by correspondence with Father Joachim Bouvet.

Certainly if Leibniz was introduced to the I Ching at this point, he would have immediately recognized it's relationship to binary numbers. Several authors such as Umberto Eco here and websites all point to Bouvet writing to Leibniz describing the I Ching, however, none of them presented a quote of Leibniz indicating that he ever knew of the I Ching, and none provided a historical reference. In any event, Leibniz knew about binary numbers before he heard of the I Ching.

Now the origin of the I Ching is murky at best, and is definitely the domain of mythology rather than historical fact. More prosaic is this view of FuXi as a set of advisors to a matriarchal tribe in ancient northwestern China. What's fascinating about the I Ching and with other systems such as Tarot is that a few simple objects in the case of the I Ching six coins can be used to generate a large number of possibilities.

Mathematically, the number of outcomes grows exponentially with the number of objects involved, and that makes using the I Ching both quick and entertaining.
