Hello Steven,
I enjoyed reading your essay and I agree with much of what you write. But one thing that peaked my interest is your discussion of Planck's Law for blackbody radiation. The very beginnings of Quantum Theory. You write,
"Five years later Einstein rederived Planck's [blackbody spectrum] results by changing the physical assumptions of the cavity oscillations of the electromagnetic field. He proposed they were quantized themselves, and thus light and all electromagnetic radiation were quantized."
Einstien's Quantum Hypothesis used to derive Planck's Law is not, however, needed to mathematically derive this result! But it was the "first" explanation. And in Physics the "first" successful explanation is often taken as "physically true"!
In my FQXi 2010 Contest essay, "A World Without Quanta?", I show how Planck's Law can be derived using continuous methods and not needing the physical assumption of "quanta". In fact, I show Planck's Law is actually an exact Mathematical Truism (like the Pythagorean Theorem) and is not really a Physical Law. (see also, "The Thermodynamics in Planck's Law")
Further, Einstein's Constant Speed of Light hypothesis contradicts his Quantum Hypothesis! Since it can be mathematically proven that "if CSL, then light is a wave"! (Proposition 11 in "The Thermodynamics in Planck's Law")
Often, the remarkable fit of the experimental curve for Cosmic blackbody radiation with the theoretical curve using Planck's Law is used to argue for the existence of "quanta"! But such confirmation is not proof. What can only explain why we have such a remarkable fit between the experimental spectra and Planck's Law is my proof that Planck's Law is an exact Mathematical Identity. Such remarkable fit we would also expect for a finely drawn circle with the Pythagorean Theorem.
In my current Contest essay, "The 'man-made' Universe", I argue all Basic Laws of Physics are Mathematical Truisms. But I also argue we cannot know "what is" the physical Universe. But can only know our measurements and understanding of "what is". Thus, the only Universe we can know is the Universe we conceive! To that end, we should be guided by an Anthropocentric Principle: Our Knowledge of the Universe is such as to make Life possible.
I welcome your thoughts on this!
