Controlled Experiments

Famous quotes containing the words controlled and/or experiments:

“I claim not to have controlled events, but confess plainly that events have controlled me.”
—Abraham Lincoln (1809–1865)

“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)
