计算物理与现实:在铁匠铺寻找一些重叠

Computational Physics and Reality: Looking for Some Overlap at the Blacksmith Shop

Nathan Moore, Nicole Schoolmeesters

摘要:

本文介绍了两个一般性的问题,在计算作业中遇到的入门级。首先,初学者经常把计算机代码当作魔法咒语,就像许多领域的新手一样,很难创造新的算法或程序来解决新的问题。其次,计算研究的性质通常意味着产生的结果是通过理论上设计的数量来解释的,与实验测量相比,这可能不符合学生的内部标准。然后,本文提供了一个实验室/编程任务,用于微积分为基础的物理课程,这是为了解决这些问题。在作业中,学生们建立了一个计算模型的热流涉及加热铁棒在铁匠的锻造。在创建模拟之后,学生们参加了一个锻造研讨会,并有机会与铁一起工作,并在焦炭燃料的锻造中获取其加热数据。回到校园后,学生们根据实验数据修改了他们的计算模型。

英文摘要:

The paper describes two general problems encountered in computational assignments at the introductory level. First, novice students often treat computer code as almost magic incantations, and like novices in many fields, have trouble creating new algorithms or procedures to solve novel problems. Second, the nature of computational studies often means that the results generated are interpreted via theoretically devised quantities, which may not meet a student's internal standards for proof when compared to an experimental measurement. The paper then offers a lab/programming assignment, used in a calculus-based physics course, which was devised to address these problems. In the assignment, students created a computational model of the heat flow involved in heating an iron rod in a blacksmith's forge. After creating the simulation, students attended a blacksmithing seminar and had a chance to work with iron and take data on its heating in a coke-fueled forge. On their return to campus, students revised their computational models in light of their experimental data.
