Re: [FRIAM] Gravity as an emergent phenomenon

Russ, I am just catching up on this but first the analogy to gas distribution is not accurate, or at least I question it from my work in solid state diffusion i.e alloys etc. There is a dynamic that ultimate results in lower energy states Interacting atoms seem to adopt a kind of neighbor

Re: [FRIAM] Gravity as an emergent phenomenon

Did Verlinde draw the scrabble metaphor? Or was it just Overbye, the NYT author? From the paper, it's not clear to me that Verlinde was implying that the straightened out (minimum entropy config?) polymer molecule was special in any anthropomorphic sense, just that it was special in the sens

Roger, Some how that seems less mysterious if you say, seal a beaker of SUGAR and a beaker of water in a bell jar. In time the sugar will become damp. By the way, help me out with the technology, here. Initially, what is the atmosphere in the bell jar composed of? Nick Nicholas S. Thom

Re: [FRIAM] Gravity as an emergent phenomenon

Hi Glen, I believe it's also called a "wedge product". Mike Spivak's tiny but frustrating but elegant book Calculus on Manifolds, if I remember correctly, defines these things and explains what they mean in geometric terms. Eric On Jul 13, 2010, at 7:30 PM, glen e. p. ropella wrote:

Re: [FRIAM] Gravity as an emergent phenomenon

Verlinde makes the same unfortunate argument that is made by scores of scientists - even noted thermodynamicsists - about so-called "disorder": namely that certain permutations are "disordered", while other permutations are not. To wit: "Think of the universe as a box of scrabble letters. Ther
