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.
“Over the tree-tops I float thee a song,
Over the rising and sinking waves, over the myriad fields and the
prairies wide,
Over the dense-packed cities all and the teeming wharves and ways,
I float this carol with joy, with joy to thee, O death,”
—Walt Whitman (1819–1892)
