The award-winning science writer and author of The Youth Pill presents a lyrical analysis of Leonhard Eulers Gods Equation, explaining its astonishing revelation of hidden connections that tie together everything from basic arithmetic to trigonometry, calculus and beyond. 25,000 first printing. An award-winning science writer introduces us to mathematics using the extraordinary equation that unites five of mathematics most important numbersBertrand Russell wrote that mathematics can exalt as surely as poetry. This is especially true of one equation: ei(pi) + 1 = 0, the brainchild of Leonhard Euler, the Mozart of mathematics. More than two centuries after Eulers death, it is still regarded as a conceptual diamond of unsurpassed beauty. Called Eulers identity or Gods equation, it includes just five numbers but represents an astonishing revelation of hidden connections. It ties together everything from basic arithmetic to compound interest, the circumference of a circle, trigonometry, calculus, and even infinity. In David Stipps hands, Eulers identity formula becomes a contemplative stroll through the glories of mathematics. The result is an ode to this magical field.
