Designed for ... Beginners'' in which he * * proposes using the symbol π (the Greek letter ''pi'', as an abbreviation for ''perimeter'') to represent the ratio of the circumference of a circle to its diameter. * * introduces John Machin's quickly converging inverse-tangent series for π (pi), enabling it to be computed to 100 decimal places. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1706 in science」の詳細全文を読む スポンサード リンク
