Hi all, I am from electronics background, yet I have studied quantum mechanics. Lately I have been reading Prigogine I., "From being to becoming". (If I am correct) the book deals with the one directional nature of time as it flows from past to present and onwards to future. But I did not get it how it was explained (or proven) in the book. The book suggests that in microscopic world the irreversibility can not be seen. But in macroscopic world when we deal with ensembles and averages the irreversibility is observed. Thus the relevance of time change can be understood. But how to really perceive this time change in microscopic world? Can irreversibility not be observed there?
