Sensitive dependence on initial conditions • London 2015 Artist - TAG. Installed July 2015









The Monarch (or King of Butterflies) is on the endangered list due to high use of herbicides used in GE Crop production across its native American habitat. Sightings in the UK are rare.

Chaos theory, aka the butterfly effect, is stated as 'the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a later state'.

The Swallowtail is our largest native butterfly, and also one of our rarest.



To a Butterfly

I've watched you now a full half-hour,
Self-poised upon that yellow flower;
And, little Butterfly! indeed
I know not if you sleep or feed.
How motionless! and then
What joy awaits you, when the breeze
Hath found you out among the trees,
And calls you forth again!
This plot of Orchard-ground is ours;
My trees they are, my Sister's flowers;
Here rest your wings when they are weary;
Here lodge as in a sanctuary!
Come often to us, fear no wrong;
Sit near us on the bough!
We'll talk of sunshine and of song;
And summer days, when we were young;
Sweet childish days, that were as long
As twenty days are now.

William Wordsworth (1770-1850).
