Thermodynamics and the Einstein-Szilard Refrigerator

The earth can make ice in the tropics. See Chimborazo (whose summit is the point on the earth's surface furthest from its center).

The Einstein-Szilard Refrigerator was patented by Albert Einstein and his former student Leo Szilard who were moved by a story of a family in Berlin dying because their refrigerator leaked toxic gases. They later become better known for their letter to Franklin D. Roosevelt encouraging the development of nuclear weapons by the United States.

John Searle's Chinese Room Argument

He's fed up with talking about this. I used to have a copy of the little book he wrote called Minds, Brains & Science. Apparently the AI at Google has read it too and gets it completely: How does stuff like this happen? Most people won't even notice what I'm saying even if I point out that the Google search changed the title. The book was really called Minds, Brains & Science , not Minds, Brains & Programs . (But maybe that was a later edition or something?) I asked Google and it said: John Searle's book Minds, Brains and Science did not become "Minds, Brains & Programs"—rather, they are two separate, distinct works published a few years apart: "Minds, Brains, and Programs" (1980): A landmark academic paper published in the journal Behavioral and Brain Sciences. This is where Searle first introduced his famous Chinese Room Argument to challenge the concept of "strong AI". "Minds, Brains and Science" (1984): A shor...

Tensor Fields and Simplicial Complexes

Listening to Freya Holmér last night I started to get glimmers of an idea I had long ago about how to represent vector spaces in computational processes using this recursive abstract type :  abstype 'a point = POINT   of {getx :  'a vector,       diff :  'a point -> 'a point,       move :  'a point -> 'a point,       scale : 'a -> 'a point,       proj :  'a point -> 'a} with    fun new i (op +) (op -) (op * ) dot =    let fun self x =  POINT       {getx = x,        move = fn (POINT pr) =>           (self (x + (#getx pr))),        diff = fn (POINT pr) =>          self (x - (#getx pr)),        scale = fn i =>          (self (x * i)),        proj = fn (POINT pr) =>     ...
