矿物学是地质学的一个分支,主要研究矿物的化学成分、晶体结构、形态、性质、成因等,对矿物资源的开发和利用具有重要的意义。在我们的印象中,研究矿物的人一定是那些与“矿”的工作有关的人员,而医生在我们的印象中则是那些穿着白大褂,拿着听诊器,专心致志为病人解除病痛、救死扶伤的人,这两者之间似乎没有什么关系。然而,矿物学研究的“开山鼻祖”尔格乌斯·阿格里科拉竟然是从一名医生开始做起的。这是怎么回事呢?
Mineralogy is a branch of geology. It mainly studies the chemical composition, crystal structure, morphology, properties and genesis of minerals, which is of great significance to the development and utilization of mineral resources. In our minds, the people who study minerals must be those related to the “mine” work, and the doctors in our minds are those who wear white coats, hold stethoscopes, concentrate on relieving the patient of illness and healing There seems to be no relationship between the two. However, mineralogical research “Aristotle ” Ergos Agri-Corra turned out to start from a doctor. What is going on?
