Cita (XIV)

Since the mathematicians have invaded the theory of relativity, I do not understand it myself anymore. --Albert Einstein

Cita (XIII)

Wir müssen wissen. Wir werden wissen. --David Hilbert

Translation: We must know. We will know.
Speech in Königsberg in 1930, now on his tomb in Göttingen

Cita (XII)

Any one who considers arithmetical methods of producing random digits is, of course, in a state of sin. --John Von Neumann

Cita (XI)

Philosophy is written in this grand book— I mean the universe— which stands continually open to our gaze, but it cannot be understood unless one first learns to comprehend the language in which it is written. It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures, without which it is humanly impossible to understand a single word of it; without these, one is wandering about in a dark labyrinth. --Galileo Galilei (1623)

Cita (X)

Aus dem Paradies, das Cantor uns geschaffen, soll uns niemand vertreiben können. --David Hilbert
(No one shall expel us from the Paradise that Cantor has created.)

Cita (IX)

You should call it entropy, for two reasons. In the first place your uncertainty function has been used in statistical mechanics under that name, so it already has a name. In the second place, and more important, no one really knows what entropy really is, so in a debate you will always have the advantage. --John Von Neumann (a Claude Shannon)

Cita (VIII)

Mathematics consists of proving the most obvious thing in the least obvious way. --George Pólya
