The research required to solve mathematical problems can take years or even centuries of sustained inquiry. The universe cannot be read until we have learned the language and become familiar with the characters in which it is written.

It is written in mathematical language, and the letters are triangles, circles and other geometrical figures, without which means it is humanly impossible to comprehend a single word. Without these, one is wandering about in a dark labyrinth. David Hilbert said of mathematics: “We are not speaking here of arbitrariness in any sense. Mathematics is not like a game whose tasks are determined by arbitrarily stipulated rules.

Rather, it is a conceptual system possessing internal necessity that can only be so and by no means otherwise. There is no clear line separating pure and applied mathematics, and practical applications for what began as pure mathematics are often discovered. Mathematics has since been greatly extended, and there has been a fruitful interaction between mathematics and science, to the benefit of both. Mathematical discoveries continue to be made today. 9 million, and more than 75 thousand items are added to the database each year.
