Pierre de Fermat

To divide a cube into two cubes, a fourth power into two fourth powers, or in general any power whatever into two powers of the same denomination above the second is impossible. I have assuredly found an admirable proof of this proposition, but the margin is too narrow to contain it.

It is not that I am so clever, but that I stick with problems longer.

I am a poor man, but I have a rich mind.

I could not resist the temptation of adding a few words on the subject of this problem, which has so long exercised the ingenuity of mathematicians.

I have found a great many truly beautiful theorems.

I am far from pretending to have discovered all the secrets of numbers.

I have no doubt that you will find this problem as amusing as I have.

I am not so much interested in the solution as in the method of finding it.

I have always been of the opinion that mathematics is the queen of the sciences.

I confess that I have not yet found a proof for this theorem, but I am confident that one exists.

I am not a professional mathematician, but I dabble in it for my own amusement.

I have often been surprised that mathematicians have not paid more attention to this subject.

I am not afraid to admit that I have made mistakes, for it is through them that we learn.

I have always found that the most difficult problems are the most rewarding to solve.

I am not a man of many words, but I hope that my actions speak for themselves.

I have always been fascinated by the beauty and elegance of mathematics.

I am not one to boast, but I believe that I have made some significant contributions to mathematics.

I have always believed that mathematics is a universal language that can be understood by all.

I am not a fan of long and tedious proofs; I prefer those that are concise and elegant.

I have always found that the best way to learn is by doing.
