All life is an experiment. The more experiments you make the better.
Ralph Waldo Emerson (1803 - 1882)
Theory is a good thing, but a good experiment is forever.
Pyotr Leonidovich Kapitsa (1894 - 1984)
If the experiments be quite simple the question may be without great importance; but when their requirements as to time or expenditure come into account the problem arises, how the observations should be chosen in order that a limited number of them may give the maximum amount of knowledge.
Kirstine Smith (1878 - 1939)
You can't fix by analysis what you bungled by design.
Richard Light, Judith Singer, and John Willett
Every time man makes a new experiment he always learns more. He cannot learn less.
Richard Buckminster Fuller (1895-1983)
...no good statistician existed unless he, or she, had been so involved in practical experimentation that they appreciated and understood the problems of the experimenter, the process worker, the farmer and the laboratory assistant.
Stella V. Cunliffe (1917 - 2012)
The true method of knowledge is experiment.
William Blake (1757 - 1827)
Science walks forward on two feet, namely theory and experiment ... Sometimes it is one foot that is put forward first, sometimes the other, but continuous progress is only made by the use of both - by theorizing and then testing, or by finding new relations in the process of experimenting and then bringing the theoretical foot up and pushing it on beyond, and so on in unending alterations.
Robert Andrews Millikan (1868 - 1953)
Experiment is the sole source of truth. It alone can teach us something new: it alone can give us certainty.
Jules Henri Poincare (1854 - 1912)
