Abstract
THE “Arrow of Time” has been much discussed by philosophers and by some scientists1, and various manifestations, which have also been offered as explanations of this directionality, are to be noted in the world around us. For example, asymmetry of time is observed in thermodynamics, an increase in entropy is predicted from statistical mechanics, there is a consistent choice of retarded solutions to time symmetric equations of radiation theory and expansion of the universe is deduced from cosmological theory; in addition a temporal arrow is inferred from the asymmetry of matter and antimatter in the universe. A striking feature of such observations is that the directions of the arrows agree.
