When modern world computing level increased then a logical conclusion raised along with constant. Making news also a business but you are trying to change a constant to a variable which is impossible.

Unnecessary exercise
by palanki narayana on Jun 28, 2011 05:14 PM

It is unnecessary to define a new entity tau which is just half the value of pi.There are several mathematical formulae which use pi which cannot be converted to convenient expressions using tau.Area of an ellipse and volume of a cylinder or sphere are examples.
Is it suggested that tau will replace the pi key in future calculators?

Replacement means nothing

In school we were taught that the area of a circle is pi times square of radius.The circumference is pi times diameter.Radius is used for one formula and diameter for the other formula.In engineering,diameter is always used.Steel bars are designated by diameter.Area of a steel bar is 0.785 times diameter squared,while the perimeter is 3.14 times diameter.It is matter of convention and habit.Nothing sacrosant about using pi or tau.In some civil engineering formulae a value of pi equal to 3 is good enough.
In an interesting book "Mathemaics made difficult" it is shown that the cube root of 31 is an excellent approximation for pi,much more accurate than 22/7

Totally wrong;how is that possible, as per Bible, Earth and all the life including humans is only 4000 years old.Don't forget-theBIBLEis straight from God.

Was there a numbering system (anywhere in the world) 60000 years ago?.

all over world, Bible has been proven false, bcoz:

dinosaurs EXISTED LAKHS OF YEARS BACK!

soil, stones have been scientifically tested, in USA/UK/EUROPE/WORLD OVER,
and found that-

they are MILLIONS OF YEARS OLD!

Bible has been proven false! by your own christian people in USA/UK/EUROPE.
