The truth of science should not be found in the dusty books of ancient saints, but should be found in experiments and theories based on experiments. - Galileo

Laboratory and invention are two closely related terms. Without a laboratory, natural science will wither; once a scientist leaves the laboratory, he becomes a disarmed warrior on the battlefield.——Pasteur

The backward thinking of "those who work hard will govern others, and those who work hard will be governed by others", which emphasizes theory and neglects experiment, is very harmful to the scientific youth of developing countries.—— Ding Zhaozhong

I don’t like boring lectures without experiments, because in the final analysis all scientific progress starts from experiments. - Oersted

All reasoning must be Obtained from observation and experiment. - Galileo

Do it yourself, move your own feet, and observe with your own eyes. This is the highest principle of our experimental work. - Pavlov

Acquire knowledge from experiments, knowledge is power - Bacon
