You do not really understand something unless you can explain it to your grandmother.

-- Albert Einstein

A. Einstein must have had an unusually insightful grandmother, or else his ability to explain relativity theory must have been unsurpassed.

And erwin Schrodinger's grandmother must really have been something. It took me two wellwritten books just to get a general grasp of what he was doing.

I think if you asked Einstein, he would probably have told you that he didn't really understand relativity.

Well lucky for us all he wasn't publishing in his grandmother's journal. If having powerful expressive models isn't "understanding" then maybe it's best we leave this concept to message boards.

It's probably a nicely self-regulating system then.

Which books, if you don't mind?

[mixmax]

Schrodingers cat by John Gribben. Check his other books as well if you want good explanations of physics

[Eliezer]

I call BS on Albert.
