We are familiar with 3² + 4² = 5², right?
But there is also 20² + 21² = 29².

Is there a general algorithm that would generate x, y and z as solution to x² + y² = z² where x, y and z are co-primes into each other?

Please help me I really wanted to know.

very very very very very very fast velocitys (mabe not light speed but in that range) so we dont have to alwys be puttin around our little lifeless boring solar system.

if theres aliens life out in space observing us, they probly roll their eyes around and throw there green hands in the air when they hear earth peopl complain that space research is such a waste of time because theres nothing to see out in space.

We need to go REALLY FAST if we want to really explore dont you think?

Aug. 27th the Whole World is waiting for......... ....

Planet Mars will be the brightest in the night sky starting August.

It will look as large as the full moon to the naked eye. This will
culminate on Aug. 27th when Mars comes within 34.65M miles of earth.

Be sure to watch the sky on Aug. 27 12:30 am (Singapore Time).

It will look like the earth has 2 Moons.

The next time Mars may come this close is in 2287.

Share this with your friends as NO ONE ALIVE TODAY will ever see it again.

(I received this from a friend in an email....)
