The factorial, like other symbols in math, has a multinational background, with roots in Switzerland , Germany and France. The radical sign, originating from Italy and Germany , has a Middle Eastern connection as well.

During this time, Arab mathematicians had the. Preceding this, Aristotle BC is noted for saying three things about infinity: i the infinite exists in nature and can be identified only in terms of quantity, ii if infinity exists it must be defined, and iii infinity can not exist in reality.

From these three statements Aristotle came to the conclusion that mathematicians had no use for infinity Guedj, Cantor not only accepted infinity, but used aleph, the first letter of the Hebrew alphabet, as its symbol see below Reimer. One of the most studied constants of all time, p , the ratio of the circumference of a circle to its diameter, 3. In , J. Sturmn, from the University of Altdorf in Bavaria , used the letter e to represent the ratio of the length of a circle to its diameter; however it did not catch on.

Pi was introduced again in by William Jones. Jones was looking over the work of John Machin and found that he used p to mean the ratio of circumference to diameter. Then Euler changed his mind again, and later in used p in his Mechanica sive motus scientia analytice exposita and then cemented it into mathematical culture with his work entitled Introductio in analysin infinitorum.
