The famous quotes about experiments are as follows:

1. The theory of natural science cannot be separated from the basis of experiment. The backward thinking of emphasizing theory and neglecting experimentation is very harmful to scientific youth in developing countries.

2. I have never made an accidental invention in my life. All my inventions are the result of careful consideration and rigorous testing. I don't like boring lectures without experiments, because in the final analysis all scientific progress begins with experiments.

3. Science gives people certainty and strength. He who relies only on practice without relying on science is like a sailor who does not rely on a rudder and a compass. Conquering the fortress of science is like fighting a war. Someone will always die and someone will be injured. I want to dedicate myself to science.

4. 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.

5. Intelligent qualifications, inner drive, hard work attitude and perseverance are other conditions required for successful scientific research. Only by entering the water can you know the depth of the water, and exploring the truth depends on practice.

6. Raising a problem is often more important than solving one. Because solving problems may be just a mathematical or experimental skill, but raising new questions requires creative imagination and marks real progress in science.

7. Science cannot be obtained without hard work. Indeed, there is no other way to achieve success in science except sweating; neither enthusiasm nor fantasy nor desire with the whole body and mind can replace labor. .

Data expansion:

Experiment refers to one of the basic methods of scientific research. According to the purpose of scientific research, try to eliminate external influences as much as possible, highlight the main factors and use some specialized instruments and equipment to artificially change, control or simulate the research object, so that certain things (or processes) occur or reproduce, so as to Understand natural phenomena, natural properties, and natural laws.
