Maxwells demon and Maxwell's robot decrease entropy!

[Maglatron]

I thought that if there was no demon, but instead - a robot that does not remember anything and does not need to remember or forget any information, and soley was programmed just to open the door when a particle was approaching the door, then entropy would decrease voila. happy new year

That thought experiment that Maxwell and Kelvin started has been going on for quite some time now.
Looking to find equilibrium in an isolated system for the mere fact the demon opens the door no longer isolates the system therefore; Heisenberg's uncertainty principle falls into play.
Look closely into my crystal ball!

then entropy would decrease voila

You forgot to account for the increase in entropy caused by the robot's energy dissipation.

 

[Maglatron]

also if the hot molecules and cold molecules on either side of the door never increase or decrease how can the robot have extra energy to dissipate? and in the example in this video the door is massless and the only dissipation is the memory getting re-set when forgetting the information!

 

[Harald Kapp]

how can the robot have extra energy to dissipate?

How can the robot act without a power source and thus dissipate energy?

 

[Maglatron]

so if it were made energy efficient then the entropy would still go up but more slowly?

thats like saying that the demon needs food and that needs to be taken into account! But it isn't in the original thought experiment!

and also the stuff about forgetting seems like bull, and I'll explain, you don't remember what time you went for a bob 4 days ago who cares anyway! surely remembering to forget takes more energy, and heat dissapation.

Active forgetting: The current understanding of memory suggests that actively forgetting irrelevant information is crucial for efficient use of our brain's resources. Holding onto every single detail would slow down thought processes and make it harder to focus on what's important.
Levels of forgetting: Not all forgetting is created equal. Some memories fade quickly (like what you had for lunch yesterday), while others last a lifetime (a loved one's face). This depends on factors like the emotional significance, repetition, and how the information was encoded in the brain.
Evolutionary benefit: From an evolutionary perspective, discarding unnecessary information made sense. Remembering where you got a bob four days ago wouldn't necessarily contribute to your survival or well-being. On the other hand, remembering where you found food or water would be crucial.
There you go Bob!

what do you think about that then?

and by the way, bob means number 2!

I think more reading is necessary.

If you have to force it, it’s probably crap.
Smell ya later...
