Explanation

William Jones, a Welsh mathematician, introduced the symbol 'π' (pi) in 1706 in his work 'Synopsis Palmariorum Matheseos.' Before this, the ratio was described in words or with other notations. Isaac Newton and Galileo made contributions to calculus and astronomy but didn't name pi. James Watt was an engineer known for steam engine improvements, not mathematical notation.
