That there are no whole number solutions to the equation:

xn + yn = zn

when n > 2.

If n = 2 this is:

x2 + y2 = z2

is known as Pythagoras' Theorem, and has many whole number solutions, eg 32 + 42 = 52, 52 + 122 = 132.

David Hilbert was born on January 23, 1862.

No because it was known by the ancient Egyptians and many other historical civilisations

Nicolas Copernicus came up with the Copernican Model of the Solar System. It described the Earth orbiting the Sun, displacing the Ptolemaic model, which placed the Earth at the centre of the universe, and formed the basis of what we know of the solar system to this very day. This is called a Heliocentric model of the universe, from Helios (the greek god of the sun, often used to show the sun himself), and Centric, (meaning around, where we get our word centre from).

yes he thought that earth and other plantes revolved around the sun not the other way around

How about: 24.00-16.00 = 8.00 out of infinite possibilities

Mostly geometry and number theory.

Ancient babylonians developed the ROOTS of Algebra long before 820AS as someone incorrectly claimed. Earliest references I saw were around Archimedes time (2,500 years ago).

Archimedes figured out what to do with algebra and gave calculus its first big push. He also gave geometry a big push, and his work in three dimensions.. Quite possibly the smartest man who ever lived..

Watch a documentary on the Archimedes palimpsest - very enlightening. HE's WELL worth studying, unlike plagiarists who came later.

Abel's complete works have been digitized, and are available online through the National Library of Norway. Convenient links to them can be found on the Abel Prize web site, http://www.abelprisen.no/en/abel/verker.html .

Rene Descartes developed the rectangular coordinate system.

Time. That's all you can do. Just give it time. I was only with my boyfriend for 9 1/2 months and he broke up with me. I was sooo in love with him. We were broken up for 3 months and got back together and I still wasnt over him after the 3 months. That's why I got back with him! But I do know that you just have to give it time. It may take lots and lots of time. Just don't ruin your life over it. You will find that one person. God has a plan for everyone. And he's made a significant other for everyone also. You will find "the one" at some point in your life. You should maybe look. Or not look and they may come to you by fate. Like I said, it just takes time. Im sorry for your loss but life does go on.

up up and away keep me in sight.

Heliocentric solar system - the planets revolve around the Sun instead of the Earth.

There cannot be any such thing as a "greatest common multiple". Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.

Descartes didn't really 'discover' things. He was a philosopher and mathematician. He is known, amongst other things, for developing the cartesian system of co-ordinates (the xy system we usually use for graphs), founding rationalist philosophy, for his work on optics, and for laying the mathematical foundations for the development of the calculus.

Rene Descartes was a French mathematician who introduced coordinated geometry in which shapes and straight line equations are plotted on the Cartesian plane.

mg/kg, it's also ppm parts per million.

Not sure that there were many contributions ofengineering to mathematics. Contributions in the other direction: lots, contributions by engineers: yes.

1 1/2 plus 4 2/3 equals 5 3/5.

X + (X+1) = 111; 2X + 1 = 111; 2X = 110; X = 55 and the other number is 56

Pythagoras. Thus the Pythagorean theorem.
