Could be localized
Επιχ.Εναντίωσης

#115516
If Hawking's argument is right, the increase of entropy could be occurring in a localized sub-system - hence it does not follow that the entropy of the universe as a whole must be increasing.

The Arrow of Time »
The Arrow of Time
The Arrow of Time ☜A map exploring some issues concerning the nature of time that lie at the boundary of physics and philosophy. The map follows up a talk to the Blackheath Philosophy Forum on 2 April 2011 by Huw Price, Professor of Philosophy and director of the Center for Time at Sydney University.☜F1CEB7

The experience of time »
The experience of time
The experience of time☜This branch of the map considers the phenomenology of time - the various ways in which time presents itself directly to our consciousness. Why do we think time has the features indicated by the passage view? The answers will hopefully enable us to connect the phenomenological to the physical.☜FFB597

Passage view components »
Passage view components
Passage view components☜The passage view refers to three aspects of how we perceive time - that it flows, has a direction and that there is a distinguished present moment - and claims that each corresponds to a feature of the real world. These matters are considered in this part of the map.☜FFB597

Flow and direction of time? »
Flow and direction of time?
Flow and direction of time?☜What underlies our sense that time flows - that there is a continuous process where the future is realized in the present and then recedes into the past? Are we directly observing a feature of the real world through the private door of consciousness (Eddington) or is something else going on?☜FFB597

Memory accretion hypothesis »
Memory accretion hypothesis
Memory accretion hypothesis ☜At all times we are aware of a stock of memories of an ordered succession of events, each with a rough or precise time-stamp. We are also aware that the stock is being constantly added to - a process of accretion. This gives rise to the sense of time flowing in the direction that memories are added.☜59C6EF

Direction is that of memory accretion »
Direction is that of memory accretion
Direction is that of memory accretion☜By convention, we identify the forward direction of the psychological arrow of time is with the direction in which our stock of memories grows.☜9FDEF6

Why aligned with thermodynamic arrow? »
Why aligned with thermodynamic arrow?
Why aligned with thermodynamic arrow?☜If memory accretion accounts for the psychological arrow of time, why are the psychological and thermodynamic arrows aligned. We dont recall instances of eggs unscrambling or shattered glass spontaneously re-assembling. Why is this so?☜FFB597

Information theoretic explanation »
Information theoretic explanation
Information theoretic explanation☜A number of physicists and philosophers have claimed that remembering - by humans or computers - can only occur in a rising-entropy environment. Such claims generally draw on the requirements for persisting and utilizing information. Two approaches to formally demonstrating this link are addressed.☜59C6EF

Argument from computation »
Argument from computation
Argument from computation☜Memory formation in a computer can only occur within an environment where entropy is increasing AND the process of memory formation in human brains is relevantly similar to that in a computer.☜98CE71

Computer memories need increasing entropy »
Computer memories need increasing entropy
Computer memories need increasing entropy☜Several authors have argued that computer memories require increasing entropy. The cited article from Stephen Hawking is one. A more formal statement of the case by L.S. Schulman is also cited. Schulmans paper appeals to Landauers Principle that ties information storage to increasing entropy.☜FF97FF

Refrigerator objection »
Refrigerator objection
Refrigerator objection☜There is no evidence that the psychological arrow, indicated by the direction of remembering, reverses when an observer is placed in a decreasing-entropy environment. We dont start remembering the future when sitting in a refrigerator - or more prosaically - an air-conditioned room.☜FFFACD
