Abstract
In this chapter we want to show how, by some sort of new interpretation of probability theory, we get an insight into a seemingly quite different discipline, namely information theory. Consider again the sequence of tossing a coin with outcomes 0 and 1. Now interpret 0 and 1 as a dash and dot of a Morse alphabet. We all know that by means of a Morse alphabet we can transmit messages so that we may ascribe a certain meaning to a certain sequence of symbols. Or, in other words, a certain sequence of symbols carries information. In information theory we try to find a measure for the amount of information.

Here, we present a hitherto unpublished treatment by the present author. 3.6 Entropy—Curse of Statistical Mechanics?
For the problem subjectivistic-objectivistic see for example E. T. Jaynes: Information Theory. In Statistical Physics, Brandeis Lectures, Vol. 3 (W. A. Benjamin, New York 1962)
Coarse graining is discussed by A. Münster: In Encyclopedia of Physics, ed. by S. Flügge, Vol. III/2: Principles of Thermodynamics and Statistics (Springer, Berlin-Göttingen-Heidelberg 1959) The concept of entropy is discussed in all textbooks on thermodynamics, cf. references to Section 3.4.
