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:
“It is not those who till the fields who eat fine rice, nor those who rear the silkworms who wear fine silks.”
—Chinese proverb.
“The world’s great day is growing late,
Yet strange these fields that we have planted
So long with crops of love and hate.”
