Observation Wheel

Famous quotes containing the words observation and/or wheel:

“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)

“The wheel and the brake have different duties, but also one in common: to hurt one another.”
—Friedrich Nietzsche (1844–1900)
