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:
“When we walk, we naturally go to the fields and woods: what would become of us, if we walked only in a garden or a mall?”
—Henry David Thoreau (18171862)
Forgotten mornings when he walked with his mother
Through the parables
And the legends of the green chapels
And the twice-told fields of infancy”
—Dylan Thomas (19141953)
