What’s the Truth About Pi?

3,800 years ago, pi’s value was identified as different than the Archimedean value used today. Why? Is there an error in Archamedes’ development of pi? See the mathematically-based answer to that question and more, including:

What value of Pi did the ancients use 3,800 years ago?
What has been hidden about the value of pi?
What if the true value of pi is not 3.141…?
Finally: the answer to the age old question of why does a negative number times a negative number equal a positive number

Is Arhcimedes' method for calculating Pi accurate?

Examine it and see for yourself

Look at the margin of error. Archimedes' value for pi (3.14) is an approximation - not an exact value. Would you accept an approximation or errors for your bank account balance? Then, why do you accept it for pi? What else may be wrong? Read the book to find out.

Real Answers You Can Prove

Is the unit circle the key to accurately calculating pi?

Read the book to see how the simple activity of a vehicle driving around a racetrack provides a clear illustration of the connection between the unit circle and pi.

Do your own simple experiments. Prove the value of pi to yourself!

Carry out your own simple experiments to accurately calculate the value of pi – using everyday materials found around your house, classroom and office.

Why is a negative number x a negative number a positive?

Finally – a REAL answer to this question! We already know that it’s true. Now see WHY it’s true with simple mathematical proof, that you can test for yourself.
