Here is the latest post from our anonymous reader:

S/he is writing, initially, about the quote I placed in my sig file.

I have included it in the sig. of this posting for easy reference.

> Heisenberg and Bohr influenced eachother a great deal. Heisenberg's
> uncertainty principle states that at any given moment you can know a
> particle's velocity but not its position and vice versa. He used matrixes
> to take all potential positions and velocities into account and discussed
> the ~probability~ of finding a particle with any of these values. The issue
> of wave-particle duality relates directly to this idea.
>
> Although Heisenberg himself claimed to have uncovered "a strangely beautiful
> picture of reality," in actuality his principle offered no visual
> representation at all. "[A]ny picture of the atom that our imagination is
> able to invent is... defective," he declared. "An understanding of the
> atomic world in that primary sensuous fashion... is impossible." Having
> reached a satisfactory mathematical explanation, he disdained of any attempt
> to discuss the concrete physical form these distinctly metaphysical ideas
> might have implied. But that is not the whole story.
>
> Heisenberg's discovery rendered Bohr's "planetary model" of the atom
> obsolete. Strictly speaking, it rendered all models are obsolete. And yet
> it has to describe reality. Thus, it has to have a physical expression in
> both the micro- and macro-realistic terms. But how do you express a
> probability visually? To answer this question Bohr delved into metaphysics.
> He used a philosophical yin-and-yang perspective to account for
> wave-particle duality, and his view of truth, eloquently expressed in your
> signature, summarizes the conflict of quantum mechanics -- and memetics,
> incidentally -- perfectly. Aspects of reality that seem to be contradictory

> Others on the list have reacted skeptically to Heisenberg on the basis of

> As far as (1) is concerned, I'm not sure I understand the critique at all.
