Did you know that Isaac Newton collaborated with Paris Hilton in a joint effort to disprove pi?

Isaac Newton died almost 300 years ago. Do you realize that it would be almost impossible for Paris Hilton to have known Isaac Newton?

What are you talking about? Newton's parents (Jesus and Cleopatra) are both only like 50 years old now which makes Netwon like 25...

Don't you mean 35?

Although 'Sus was a loose cannon Cleopatra wanted to wait until marriage which came when she was 25. Or so the history books say...

Ah, pi: the rational number everyone seems to think is irrational.

Lol, yeah. It's circumference over diameter. Everyone knows that. 8-)

Diameter you fool. Oh, and find me a circle where the diameter and circumference are both integers. Then I'll believe that pi is rational.

If, inside a circle, a line
hits the centre and twice hits the spine
and the line's length is d
the circumference will be
d times 3.14159

what number do I divide by another number to get pi? everybody is like "22 over 7" and you do the math and it doesn't equal pi.....

You can't divide two integers together to get pi.

It can only be approximated, that is why it is called an "irrational number".

however, true circles are completely irrational, too... so it has company :lol:

When the quantum computer becomes commonplace pi will be calculated past 1,000,000,000,000,000,000,000,000,000,000 decimal places.

Once this happens the true nature of pi will be unlocked and with that will come the knowledge and technology that will allow mankind to bridge the gap between space/time and eternity.

Pi is considered to be irrational because current knowledge/understanding/technology would not permit otherwise.

So you're basing the fact that pi is only theoretically (by which I mean based on what we know about it) irrational because a nonexistent computer will be able to solve pi's mystery?

Being an irrational number, π cannot be written as the ratio of two integers. This was proven in 1761 by Johann Heinrich Lambert.In the 20th century, proofs were found that require no prerequisite knowledge beyond integral calculus. One of those, due to Ivan Niven, is widely known.A somewhat earlier similar proof is by Mary Cartwright.

Furthermore, π is also transcendental, as was proven by Ferdinand von Lindemann in 1882. This means that there is no polynomial with rational coefficients of which π is a root.An important consequence of the transcendence of π is the fact that it is not constructible. Because the coordinates of all points that can be constructed with compass and straightedge are constructible numbers, it is impossible to square the circle: that is, it is impossible to construct, using compass and straightedge alone, a square whose area is equal to the area of a given circle.
