He is now a proponent of tau. It is evident everywhere in nature and the patterns of our world--from the spiral in the center of a sunflower, to the swirl of a nautilus shell or the whirlpool of a galaxy. In fact, almost every mathematical equation about circles is written in terms of r for radius.

But where does math come from and why does it work so well to explain our physical world? Mario Livio, a notable astrophysicist who helps operate the Hubble Space Telescope from Space Telescope Science Institute, has spent much time wrestling with such questions and sees an uncanny accuracy in the way mathematics can reveal the secrets of the universe, making it seem an inherent part of nature.

But reasons for switching Math reaction pi tau are deeply rooted in pedagogy as well. The Greeks used formal geometric proofs to estimate the circumference-to-diameter ratio.

To him, these simple mathematical relationships produced the most beautiful, harmonious musical tones. In early civilizations a diameter was an easier quantity to measure than a radius.

For mathematicians, pi obscures some of the underlying symmetries of mathematics and muddies up what should be elegant with extraneous factors of two.

So when the Babylonians or Egyptians wanted rules of thumb for their architecture, a ratio of circumference to diameter is what they turned to. Indeed, the whole problem began as a historical accident, tauists say. When the elegance of math meets the messiness of reality, engineers shift into the domain of approximation rather than absolutes.

Rather, according to The Tau Manifesto"pi is a confusing and unnatural choice for the circle constant. Others, like physicist and MIT professor Max Tegmark, go a step further, arguing that mathematics is our physical reality.

Yet his choice of comparing the circumference with diameter was arbitrary; he could just as easily have used radius instead. Manifesto author Michael Hartl received his PhD in theoretical physics from the California Institute of Technology and is only one in a string of established players beginning to question the orthodoxy.

Asked in an e-mail about the reaction his original piece has received, Palais is humbled. Archimedes he of the lever and shouts of "Eureka!

Three quarters around the same circle has gone one and a half pi radians. By contrast, a third of a circle is a third of tau. All of these are a result of a set of mathematical equations published in the s by a Scottish mathematical physicist, which then inspired the work of Guglielmo Marconi, who later ushered in the era of the wireless telegraph and radio at the turn of the century.

Precision may be sacrificed for practicality if it garners results, making mathematics appear a very human invention. Follow him on Twitter rcbarthol Recent Articles. Last year the University of Oxford hosted a daylong conference titled "Tau versus Pi: Mathematician and poet Mike Keith once wrote a 10, word poem dedicated to the first 10, digits of pi.In fact, almost every mathematical equation about circles is written in terms of r for radius.

Tau is precisely the number that connects a circumference to that quantity. But usage of pi extends far beyond the geometry of circles.
