Domains of Conception
The Borders of Understanding My molecular biologist friend, Barry Bowman, brewed up this stimulating thought: One can understand much about nature without mathematics. Can one understand quantum mechanics only through its arcane mathematics? Can one not comprehend quantum physics other than through its mathematical expression? To explore the thought some agreement is needed on the…

Axioms
Hypotheses I cannot prove; taken on faith I’m thinking about my axioms of faith. On what unprovable hypotheses do I confront the world. My axioms are my prejudices; the fewer the better. The first one is this: 1. That reality exists. That a world exists in whose catalogue of entities I am one. And what…

What is Energy?
An Abstract Reality What IS energy; that you buy it, use it, have it and notice it in others? (“The kids have such energy!”) You never see it, never touch it. Never smell it or hold it. What is the nature of such a substance? Energy is not coal. Nor oil. Nor sunshine. Nor boys…

The Equation
An equation is a statement that says ‘this equals that’. It’s hard to imagine, from that raw and basic idea, that something called an equation could be of any use. Whether ‘this equals that’ or not seems a matter of little consequence! But, in fact, we know that to state what things are equal can…

Measurement Problem
A commonplace computational practice in quantum mechanics generates the most profound conceptual challenge to the theory. The challenge is called the measurement problem. Here are some quotes summarizing the problem. “The quantum measurement parodox.. stated succinctly… In quantum mechanics all possibilities… are left open whereas in … experience a definite outcome always (occurs).” A. J.…
