Subject: Re: [math-fun] A Scientist Takes On Gravity

Frederick W Kantor's 1977 book _Information Mechanics_ says that energy must correspond to information, and then works out consequences

That can't be right--they have different units! Perhaps energy corresponds to information *at a given temperature*. Landauer's principle says the energy required to erase a bit is E >= k_B T ln 2

of that in ways I didn't understand when I had a copy.  But I do remember his explaining gravity in terms of information:

"That is, energy and information are released when two objects are brought nearer each other.  From this, I next construct a picture for gravity."

Here's a paper from 1974 introducing information mechanics:  http://www.gravityresearchfoundation.org/pdf/awarded/1974/kantor.pdf
