After exponential quantities the circular functions, sine and cosine, should be considered because they arise when imaginary quantities are involved in the exponential.
Leonhard EulerRead
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.
Interpretation
The universe operates under precise mathematical laws set by a wise Creator, reflecting principles of optimization.
Leonhard Euler emphasizes the idea that the universe is a well-ordered and harmonious creation, governed by rules of optimization. Every event or phenomenon within it adheres to these principles, highlighting the significance of mathematics and logic in understanding the cosmos. This perspective invites deeper contemplation about the relationship between science, mathematics, and the divine ordering of existence.

After exponential quantities the circular functions, sine and cosine, should be considered because they arise when imaginary quantities are involved in the exponential.
To those who ask what the infinitely small quantity in mathematics is, we answer that it is actually zero. Hence there are not so many mysteries hidden in this concept as they are usually believed to be.
Notable enough, however, are the controversies over the series 1 - 1 + 1 - 1 + 1 - ... whose sum was given by Leibniz as 1/2, although others disagree. ... Understanding of this question is to be sought in the word "sum"; this idea, if thus conceived - namely, the sum of a series is said to be that quantity to which it is brought closer as more terms of the series are taken - has relevance only for convergent series, and we should in general give up the idea of sum for divergent series.
Why do more than 40 percent of Americans think that the Universe began after the domestication of the dog?
In the good old days physicists repeated each other's experiments, just to be sure. Today they stick to FORTRAN, so that they can share each other's programs, bugs included.
Any one who considers arithmetical methods of producing random digits is, of course, in a state of sin. For, as has been pointed out several times, there is no such thing as a random number - there are only methods to produce random numbers, and a strict arithmetic procedure of course is not such a method.
No one undertakes research in physics with the intention of winning a prize. It is the joy of discovering something no one knew before.
The true scientific understanding of the nature of existence is so utterly fascinating; how could you not want people to share it? Carl Sagan, I think, said 'when you're in love, you want to tell the world.' And who, on understanding a scientific view of reality, would not, as it were, fall in love and want to tell the world.
People often ask me why I persisted in doing research on a subject that was so controversial. I frequently respond by telling them that only a few scientists are granted the great fortune to pursue topics that are so new and different that only a small number of people can grasp the meaning of such discoveries initially.
