数学虽然是一门极为抽象的科学,但是它是从現实中来的,并且在其他科学中,在技术中,在全都生活实践中都有广泛的应用。一切“精确科学”例如力学、天文学、物理学等通常在研究它們的对象时不只要总結成描述性的規律,而且更进一步用一些公式来表达自己的规律,并且在发展它們自己的理論的时候,也广泛地运用数学工具。化学大体也是这样的。生物現象是比较复杂的,因而数学方法对生物学所起的作用在本质上不同于它在物理学中所起的作用。在历史上有很多例子足以說明数学方法在天文物理等学科中起着很大的作用,我們只举出一个例子来看看: 上一世紀法国物理学家弗列湼尔詳尽地論証了光的波动說,他說光是能媒的振盪,并不象牛顿和牛顿的继承者們所說的那样是粒子流。另一个著名的学者普阿松对弗列湼尔的理論进行了数学加工,他导出了表示光波传播定律的公式,并且宣称如果弗列湼尔的理
Although mathematics is an extremely abstract science, it comes from reality, and in other sciences, in technology, it is widely used in all life practices. All “accurate sciences” such as mechanics, astronomy, physics, etc. usually do not only summarize the descriptive laws when studying their objects, but further use some formulas to express their own laws and develop their own theories. , also widely used mathematical tools. The same is true of chemistry. Biological phenomena are complex, and therefore the role of mathematical methods in biology is fundamentally different from the role it plays in physics. There are many examples in history that illustrate that mathematics plays a major role in astronomy and other disciplines. We only give one example to look at: The French physicist Freignier elaborated light in the last century. The volatility said that he said that the light is an oscillation of the energy media, not a stream of particles as Newton and Newton’s successors said. Another famous scholar, Puasong, performed mathematics on Freignel’s theory. He derived a formula that represents the law of light wave propagation, and declared that if Freignel’s theory
