Very interesting post Betty.
Thanks.
As you are the host of this thread, may I ask your permission to correct something I said before, for the record?
I described the late Robert Rosen as a "mathematician and physicist." I think it would be more truthful and correct to say: He was a world-class mathematician, and theoretical biologist. Though I'm sure he had a pretty good grip on physics, as well.
I find him one of the most interesting biological theorists I've come across lately. He definitely "thinks outside the box."
Thank you so much for your hospitality!
