minus-squareRobotToasterlinkfedilinkarrow-up28·1 month agoIf a Maxwell’s demon was ever proven practical it would basically disprove the second law of thermodynamics.
minus-squarebitfucker@programming.devlinkfedilinkarrow-up9·1 month agoWait, why? What does knowing a perfect state of system has to do with the law of thermodynamics?
minus-squarejsomae@lemmy.mllinkfedilinkarrow-up3·1 month agoMaxwell’s demon knowing in advance the exact state of the system isn’t really practical as a solution. Sure you can concoct such a situation, but that isn’t useful.

minus-squareTurun@feddit.delinkfedilinkarrow-up9·1 month agoYes, but potentially less than is gained by the separation.
minus-squareFiskFisk33@startrek.websitelinkfedilinkarrow-up4·1 month agoSure, but that is like saying potentially my pig might grow wings and start flying. I mean I guess, but my pig is probably statistically significantly more likely to fly off than entropy is to decrease with time.

minus-squareValmond@lemmy.mindoki.comlinkfedilinkarrow-up1·1 month agoYou can do this (theoretically) in a closed (small) system, but not in the whole universe, so entropy wins in the end anyways.
