The Gardner–Salinas braille codes are a proposed method of encoding mathematical and scientific notation linearly using braille cells for tactile reading by the visually impaired. The most common form of Gardner–Salinas braille is the 8-cell variety, commonly called GS8. There is also a corresponding 6-cell form called GS6. [1]
The character tables of Braille's 1829 publication. As in modern braille, most of the higher decades were derived from the first: Decades 1–4 were the same as today and had their modern French values. Decade 5 was not derived from the first. (See image at left or table below.) Like the first decade, only the top half of the cell was used. [2]
where the word premier, French for "first", can be read. Braille was based on a tactile code, now known as night writing, developed by Charles Barbier. (The name "night writing" was later given to it when it was considered as a means for soldiers to communicate silently at night and without a light source, but Barbier's writings do not use this term and suggest that it was originally designed ...
The 64 braille patterns are arranged into decades based on the numerical order of those patterns. The first decade are the numerals 1 through 0, which utilize only the top and mid row of the cell; the 2nd through 4th decades are derived from the first by adding dots to the bottom row; the 5th decade is created by shifting the first decade downwards.
For example, ⠌ dots 3-4 represents / in Braille ASCII, and this is the Braille slash, but ⠿ dots 1-2-3-4-5-6 represents =, and this is not the equals sign in Braille. Braille ASCII more closely corresponds to the Nemeth Braille Code for mathematics than it does to the English Literary Braille Code, as the Nemeth Braille code is what it was ...
Richard Short, a St Ives master mariner, wrote to the Shipping and Mercantile Gazette the day after the news of the sinking broke to note: "[H]ad there been a light on Godrevy Island, which the inhabitants of this town have often applied for, it would no doubt have been the means of warning the ill-fated ship of the dangerous rocks she was ...
