At the beginning of the 20th century, physicists such as Planck, Ball, and others jointly created quantum mechanics, which together with relativity is considered to be the two basic pillars of modern physics. The development of quantum mechanics revolutionized the structure of matter for people. And the understanding of their interactions. With the help of quantum mechanics, many phenomena can be truly explained, new phenomena that cannot be imagined by intuition are predicted, and then verified. The birth of theories such as quantum mechanics has helped promote the progress of world civilization. It is of far-reaching significance. The scientific value of these years-long basic research results is inestimable, and it can never be measured by simple standards such as "useful or not. ". What does this passage mean? ['Scientific research requires long-term accumulation.', 'Quantum mechanics is of great significance to modern physics.', 'Fundamental research is not emergency.', 'Scientific value cannot be measured with quantitative indicators.']
