Famous quotes containing the words thought and/or experiments:

“I am continually amazed at how old young has become. Didn’t we, like our grandchildren, begin with a childhood we thought would never end? Now, all of a sudden, I’m older than my parents were when I thought they were old.”
—Lois Wyse (20th century)

“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)
