“The true method of knowledge is experiment.”
— William Blake Primary source“Development of Western science is based on two great achievements: the invention of the formal logical system (in Euclidean geometry) by the Greek philosophers, and the discovery of the possibility of finding out causal relationships by systematic experiment (Renaissance).”
— Albert Einstein Primary source“I simply experiment, an endless seeker, with no Past at my back.”
— Ralph Waldo Emerson Primary source“The test of all knowledge is experiment. Experiment is the sole judge of scientific truth.”
— Richard Feynman Primary source“All advances in engineering are tested first on small-scale models, in wave tanks, or in wind tunnels. Without models, the research would be prohibitively expensive, and progress would be correspondingly slow.”
