Neptune/observation

Famous quotes containing the words neptune and/or observation:

“But we are spirits of another sort.
I with the morning’s love have oft made sport,
And like a forester the groves may tread
Even till the eastern gate, all fiery-red,
Opening on Neptune with fair blessèd beams,
Turns unto yellow gold his salt green streams.”
—William Shakespeare (1564–1616)

“There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.”
—Denis Diderot (1713–1784)
