Carl Friedrich Gauss

One must learn by doing the thing; for though you think you know it, you have no certainty until you try.

The objects of mathematical inquiry are not objects of sense, but of pure thought.

The most beautiful theorems of higher arithmetic have this peculiarity, that they are easily discovered by induction, but their proof lies so deep that it is only with the greatest difficulty that one succeeds in finding it.

The further we penetrate into the realm of mathematics, the more we find that it is a world of pure thought, independent of our senses.

The problem of distinguishing prime numbers from composite numbers and of resolving the latter into their prime factors is known to be one of the most important and useful in arithmetic. It has engaged the industry and wisdom of ancient and modern geometers to such an extent that it would be superfluous to discuss the matter at length.

Mathematics is the science of the eternal and the immutable.

The true mathematician is a poet, a creator of patterns, a weaver of dreams.

The world would be a much better place if everyone understood mathematics.

The most beautiful thing we can experience is the mysterious. It is the source of all true art and science.

I have no doubt that the universe is governed by mathematical laws.

The world is full of wonders, but we often fail to see them.

The true value of a man is not in what he has, but in what he is.

Mathematics is the language in which God has written the universe.

The greatest discoveries are made by those who are not afraid to fail.

The human mind is capable of understanding the most complex things.

The beauty of mathematics lies in its simplicity and elegance.

The pursuit of knowledge is a noble endeavor.

Life is a journey, not a destination.

The only way to do great work is to love what you do.

The universe is a vast and mysterious place.
