  • ORIENTATION


    Philosophy: the braille code for mathematics is especially designed for the representation and transcription of mathematical and scientific notation. Its purpose is to convey, as accurately as possible, a clear conception of the printed text to the braille reader. Using braille indicators in conjunction with the 63 braille characters, this code is capable of providing equivalent symbols for the hundreds of mathematical and scientific ink-print signs now in use and yet to be devised. The one-to-one correspondence between braille and ink-print symbols makes it possible to produce an accurate transference from ink-print to braille or from braille to ink-print.

    Nontechnical and technical texts:

    1. Nontechnical texts: For the purposes of the Nemeth code, a nontechnical text is any work in which no mathematical or scientific notation appears. Such texts must be transcribed in accordance with the rules of English braille.
    2. Partially technical texts: a partially technical text is a science book or a work which utilizes a small number of mathematical symbols. Such texts must be transcribed according to the rules of English braille. However, when the replacement of symbols by words is not practical or possible, or when the mathematical display is used for solving equations or performing computations, the symbols and rules of the Nemeth code must be used, and the braille reader so advised. A list of the special symbols being used must be placed at the beginning of each braille volume in which they occur.
    3. technical texts: a technical text is a work in the field of mathematics, statistics, physics, or chemistry. Such texts must be transcribed entirely according to the rules of the Nemeth code
