The Physics Teacher, 1967
This article is taken from an introductory textbook by the author, scheduled for publication early in 1968; it represents the concluding section of a chapter on entropy and the second law of thermodynamics. It attempts to draw together the microscopic and macroscopic threads of physics as applied to the concept of time.

Abstract ‘The arrow of time’ discusses where the arrow of time comes from. The fundamental laws of motion do not distinguish past and future. And yet the everyday world is full of manifestly asymmetric processes. This chapter discusses the apparent mismatch between the fundamental laws of nature and the manifest asymmetry of the everyday

We are commemorating the work of a great scientist — Josef Loschmidt. Inevitably, we look at his achievements through modern eyes. My aim will not only be to look at one of his contributions, the so-called Loschmidt paradox, from my own point of view, inevitably involving more recent knowledge, but also to draw attention to the philosophical background

We argue that if everything there is in the world is physical, then time has an objective direction. If the fundamental equations of motion are time reversal invariant we show that the direction of time cannot be explained by anything else in physics (e.g. the direction of processes in time) and therefore must be added to physics. We further argue that

Space and time are the most fundamental ideas of the scientist’s picture of the world, and also of the language in which we all describe our thoughts and sensations. We use the concepts of space and time to “relate” ourselves to world phenomena that we and other people observe and to “verify” that what other people report to us as “their observations ...

Abstract Could time run backwards? When we try to visualize this, we imagine something like a film being shown in reverse. But to imagine this is to imagine being outside the process we are observing. As an observer, we are not ourselves in the film (even if we are watching a film of ourselves, for the person we are watching on the ...
