Two aspects of psychology and physiology of time are dealt with in this paper: the way time perception was increasingly studied during the 19th century by scientists, including many physicists, and the way the temporal properties of the nervous system were discovered and explored by physiologists. The neurophysiological correlation between both aspects still remains to be explained. The relatio...

Let A be a Hausdorff space, <p a continuous mapping of A into itself. It is the purpose of the present paper to discuss various topics centering around the following question: If g is a bounded continuous function on A, does there exist a bounded continuous function/on A such that/(0a)— /(a) =g(a) for all a in At Suppose that for each «o in A, the set {<pna0, re2:0} is dense in A. Theorem 1 ass...
