"Imagination is more important than knowledge." Albert Einstein
"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 to find out causal relationships by systematic experiment (during Renaissance)." Albert Einstein (1953)
