Physics:

February 2, 2004

Matter can be neither created nor destroyed,

But in an isolated system

Will be conserved in perfect balance,

Interplaying with its attendant energy,

According to the laws of nature and of nature’s God.

And in a universe of mysteries,

The greatest and rarest mystery of all,

That in a small quantity of collected atoms

From time to time

Matter and energy exist in equipoise,

The one supporting the other;

A hybrid

For a time, or a lifetime, or less

But at a great cost,

For there is no isolated system in this or any other universe.

The only matter that matters will

Inevitably

Be separated from its indwelling energy

And the energy departs

We do not know where

All that is left behind is matter,

And matter is the only thing that will mark the passing of energy --

A spark, a puff of wind, a moving shadow perhaps

The things we choose to mark its passing,

Bare matter themselves,

Wood, metal, stone,

A folded sweater, a dusty book,

Or random energy,

A dream, a memory,

Faulty firing of synapses

A sound, the soft click of a lid as it closes on a life

A flicker at the edge of thought

A strain of music—

All these things will last longer than the matter

That has been severed and cannot return to us,

Until we shall go to it.
