# Hazelnut Forest

This perhaps should come with the warning, ‘Let the reader who can, understand.’
(Why a hazelnut forest? LHC? Who was the Sybil of Cumae?)

Small clues: LHC is the Large Hadron Collider, the largest machine ever built on Earth (27 kilometres across) with which many new particles, some expected, some not, have been discovered. Other clues are hidden in the tags, but not in the correct order (WordPress shifts them into alphabetical order).

Some time in April (I promise!) I shall write an explanation. I also promise (don’t look at my crossed fingers) that the explanation will not itself need explaining.

How small is the forest?
How tiny its leaves?
Where the pattern of branches
tosses and weaves;
and the canopy sways,
and the summer winds moan,
until shortening days
say summer is gone.

Halfway in the forest
its deepest heart;
where calling birds fly
to its farthest part,
and the leaves’ rustling sigh
gives place to the sky,
and the height of the trees,
and the birds flying free,
and the tiniest leaves,
are the forest to me.

How Small is The Forest?

How far is it from constancy
to Heisenberg’s uncertainty?
A tiny length defines
a volume that we find:
the smallest we can know.
A fundamental distance
that we call Planck’s length (L)
shows there is a thickness
we cannot go below.

A circle has a volume just like a carousel
the volume of a circle is pi times r squared L,
(by this we come to see
there is no ‘true’ 2D
and a circle without volume,
is an anomaly).

A Circle With a Volume

This volume hides a mystery.
How small can it be?
How can it be measured,
a space too small to see
by eye or LHC?

The smallest space we cannot see:
the rings inside, the rings inside,
the rings inside a tree,
is found from four-thirds pi
times its depth to power of three.

This volume, this conundrum,
too veiled for us to see,
a mystery its diameter,
its radius an enigma,
the Sybil of Cumae,
time in eternity.

Radius is half of width,
we know that very well
but half a fundamental
is a word we cannot spell.
Diameter equals radius,
it flickers to and fro,
in the tiniest of instants,
the shortest we can know.

Things fall apart, the centre cannot hold.
Fission and expansion, a cosmos to unfold.

A whole that ever seeks
the shimmer and the chime,
Infinite from finite
in the infinite-finite rhyme:
the Word that ever speaks
at the birth and death of time.
