Michael Hartl  
"This manifesto is dedicated to one of the most important numbers in mathematics, perhaps the most important: the circle constant relating the circumference of a circle to its linear dimension... The traditional choice of circle constant is π  but, as mathematician Bob Palais notes in his delightful [2001 Mathematical Intelligencer] article, "π Is Wrong!," pi is wrong. It's time to set things right." Hartl, a theoretical physicist, goes on to introduce τ as "the natural choice for the circle constant," argue the benefits of "a more natural definition" in an "immodest proposal," and show the implications of its choice on formulas such as Euler's identity.
