Other Fields
Many physical quantities are actually quantized by physical entities. Examples of fields where this limitation applies include electronics (due to electrons), optics (due to photons), biology (due to DNA), and chemistry (due to molecules). This is sometimes known as the "quantum noise limit" of systems in those fields. This is a different manifestation of "quantization error," in which theoretical models may be analog but physically occurs digitally. Around the quantum limit, the distinction between analog and digital quantities vanishes.

Famous quotes containing the word fields:
“a child’s
Forgotten mornings when he walked with his mother
Through the parables
Of sunlight
And the legends of the green chapels
And the twice-told fields of infancy”
—Dylan Thomas (1914–1953)
“Or seen the furrows shine but late upturned,
And where the fieldfare followed in the rear,
When all the fields around lay bound and hoar
Beneath a thick integument of snow.
So by God’s cheap economy made rich
To go upon my winter’s task again.”
—Henry David Thoreau (1817–1862)
