数学在物理学中的应用2.估计

Using math in physics -- 2. Estimation

Edward F. Redish

摘要:

学习在科学中使用数学是一项重要的任务。它涉及许多不同的技能(通常不在数学课上教授),有助于将物理知识与数学符号相结合。其中之一是量化的思想:物理量可以被赋予特定的数字。第二是培养对规模的直觉。帮助学生发展这些技能的一种方法是教授估计:考虑物理情况并将合理的近似数字放入其中的能力

英文摘要:

Learning to use math in science is a non-trivial task. It involves many different skills (not usually taught in a math class) that help blend physical knowledge with mathematical symbology. One of these is the idea of quantification: that physical quantities can be assigned specific numbers. A second is to develop an intuition for scale. One way to help students develop these skills is to teach estimation: the ability to consider a physical situation and put reasonable approximate numbers to it
