Historically the concept of infinity was in parallel created in the different fields of scientific and practical activities of the person. Therefore there are definitions of this concept differing among themselves, for example, in physics, theology and mathematics. Nevertheless, from the middle of the seventeenth century for an infinity symbol in printing works in different fields of knowledge the same symbol began to be used.
Instruction
1. Designate infinity by the eight turned on 90 ° - this symbol today became universal and is applied more often any other. To such designation you can choose treatment on the taste - for example, it can be a symbol of a ring of Möbius having conditionally infinite length of a surface. However, at the time of an exit of the first of the remained printing works with such designation of infinity (John Wallis, De sectionibus conicis, 1655) this ring was not patented yet.
2. Other option - snakes, devouring the tail which for one and a half thousand years in Egypt symbolized B.C. various processes which do not have the beginning and the end. It is possible to find similar symbols and in the Indian or Chinese religious and philosophical doctrines.
3. For an insert in electronic documents which support tables Unicode coding use value 8734 - under this serial number in such table the infinity symbol is placed. In application programs of the Windows operating system for an insert of signs with use of these codes a certain procedure is used.
4. Install the cursor in the necessary position in the electronic document, then press the Alt key and type the code on additional (digital) infinity sign will appear on the page of the document. If it does not occur, then it will mean that the format of the document does not support work with Unicode symbols. In such formats those that are stored in files with the txt expansion belong to documents, for example.
5. To place an infinity symbol in the page of the website, it is necessary to insert into its source code or the code stated above (as appropriate having issued it), or the special sequence of signs relating to special designations - to "symbolical primitives". In the first case such character set is used: & #8734; in in the second - & infin;.
