Controlled Experiments

Famous quotes containing the words controlled and/or experiments:

“Babies control and bring up their families as much as they are controlled by them; in fact ... the family brings up baby by being brought up by him.”
—Erik H. Erikson (1904–1994)

“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)
