The aim of this paper is to examine critically Lucas’ arguments against Keynes’s General Theory and in particular against Keynes’s concept of involuntary unemployment. It comprises two main parts. In the first, I question Lucas’s claim that Keynes betrayed the equilibrium discipline by freeing himself from the postulates of optimising behaviour and market clearing. In the second, I discuss Luca...

Tarski’s 1936 paper, “On the concept of logical consequence”, is a rather philosophical, non-technical paper that leaves room for conflicting interpretations. My purpose is to review some important issues that explicitly or implicitly constitute its themes. My discussion contains four sections: (1) terminological and conceptual preliminaries, (2) Tarski’s definition of the concept of logical co...

The second and the third law of dynamics are stated for an isolated pair of material points at rest, in a form which does not involve the concept of force. By means of the third law of dynamics, it is proved that the ratio of two masses is independent of the choice of the refe...

This analysis examines the accuracy, utility and ...

In his work on the information content of English text in 1951, Shannon described a method of recoding the input text, a technique which has apparently lain dormant for the ensuing 45 years. Whereas traditional compressors exploit symbol frequencies and symbol contexts, Shannon’s method adds the concept of “symbol ranking”, as in ‘the next symbol is the one third most likely in the present cont...
