Heraclitus as Quantum Physicist

Someone just asked me who Heraclitus was.  A Greek philosopher I said.  Phew, I thought, when I looked up the wikipedia entry to show to that person - it certainly said he was a Greek philosopher (got that one right).  Reading through the article, I came across this:
In Heraclitus a perceived object is a harmony between two fundamental units of change, a waxing and a waning. He typically uses the ordinary word "to become" (gignesthai or ginesthai, root sense of being born), which led to his being characterized as the philosopher of becoming rather than of being. He recognizes the changing of objects with the flow of time.

Plato argues against Heraclitus as follows:[57] - from Cratylus Paragraph 440 sections c-d.

How can that be a real thing which is never in the same state? ... for at the moment that the observer approaches, then they become other ... so that you cannot get any further in knowing their nature or state .... but if that which knows and that which is known exist ever ... then I do not think they can resemble a process or flux ....
(from http://en.wikipedia.org/wiki/Heraclitus, accessed 19th March 2013).

The Plato quote, especially the part "for at the moment that the observer approaches, then they become other", seems to indicate that maybe Heraclitus was an original quantum physicist - stating a formulation of the observer effect (partially related to the uncertainty principle).

Heraclitus is an interesting read - worthwhile re-acquainting oneself with his work.
