If a nonnegative quantity was so small that it is smaller than any given one, then it certainly could not be anything but zero. To those who ask what the infinitely small quantity in mathematics is, we answer that it… — Leonhard Euler Copy Share Image
For since the fabric of the universe is most perfect and the work of a most wise Creator, nothing at all takes place in the universe in which some rule of maximum or minimum does not appear. — Leonhard Euler Copy Share Image
Nothing takes place in the world whose meaning is not that of some maximum or minimum. — Leonhard Euler Copy Share
Although to penetrate into the intimate mysteries of nature and thence to learn the true causes of phenomena is not allowed to us, nevertheless… — Leonhard Euler Copy Share
A function of a variable quantity is an analytic expression composed in any way whatsoever of the variable quantity and numbers or constant quantities. — Leonhard Euler Copy Share
Thus you see, most noble Sir, how this type of solution to the Königsberg bridge problem bears little relationship to mathematics, and I do… — Leonhard Euler Copy Share
The kind of knowledge which is supported only by observations and is not yet proved must be carefully distinguished from the truth; it is… — Leonhard Euler Copy Share
Since the fabric of the universe is most perfect and the work of a most wise Creator, nothing at all takes place in the… — Leonhard Euler Copy Share

Logic is the foundation of the certainty of all the knowledge we acquire. — Leonhard Euler Copy Share
For the sake of brevity, we will always represent this number 2.718281828459... by the letter e. — Leonhard Euler Copy Share
In the meantime, most noble Sir, you have assigned this question to the geometry of position, but I am ignorant as to what this… — Leonhard Euler Copy Share
For since the fabric of the universe is most perfect and the work of a most wise Creator, nothing at all takes place in… — Leonhard Euler Copy Share
Mathematicians have tried in vain to this day to discover some order in the sequence of prime numbers, and we have reason to believe… — Leonhard Euler Copy Share
To those who ask what the infinitely small quantity in mathematics is, we answer that it is actually zero. Hence there are not so… — Leonhard Euler Copy Share
