国科大教师赵亚溥:愿为学生吹响“悠扬笛声”
 
赵亚溥在国科大《力学》一年级本科课程授课中

■本报见习记者 韩扬眉 记者 肖洁
1895年,16岁的爱因斯坦在阅读一本科普书对太空和行星的描述时突发奇想:“如果进行‘太空旅行’,应该乘坐什么交通工具?”此后的一个晚上,他在梦里做了一个“追光实验”,这个“梦”为其十年后建立狭义相对论孕育了思想上的萌芽……
主修过赵亚溥《力学》课的学生都知道这个故事,这是他在讲解“狭义相对论的拉格朗日量”时所提到的。不直接解释概念、推导公式,而从故事入手,用短短5分钟的时间,很自然地将狭义相对论引入课堂,当同学们听得入迷之时,他“趁机”推导闵可夫斯基等公式。
中国科学院大学(以下简称“国科大”)本科生授课教师赵亚溥深受爱因斯坦“想象力比知识更重要”论断的影响,并将这一理念贯穿至教学始终。
“你可以质疑最顶级期刊!”
对于本科生的经典力学课程来说,建立物理图像是首要任务,这需要丰富的想象力,以“思想实验”为主线来讲授再好不过了。
牛顿的水桶思想实验、“萨尔维阿蒂的大船”、芝诺佯谬……在赵亚溥的课堂上,不断上演的理性思维活动,让学生们觉得既生动形象又“烧脑”,既充满挑战又让人很受启发。
在科研一线拼搏近三十年后,曾作为中国科学院力学研究所研究员的赵亚溥走上教师岗位。他曾反思:当代科学迅猛发展,已经从传统的科研方法发展到全新的科研方法,即从现有科学理论系统出发,进行思想实验,预测某个待发现的科学理论,再设计相关实验来证实这个思想实验。
赵亚溥也非常注重培养学生的批判性思维和质疑精神。他曾在《材料力学》课的一道期中考试题中“故意设置陷阱”,选择物理学最著名的国际期刊《物理评论快报》中的一篇文献作为材料,要求考生判断文献中所推导的公式是否正确。
已经被美国哥伦比亚大学录取为博士生的2014级国科大本科材料学专业的董亦楠对此记忆犹新:“看似十分困难,但其实只要经过仔细的推演就可以发现,这公式根本不对。”
赵亚溥希望他教出来的学生“即使是最顶级期刊的内容,也可以质疑”。
教出新知识的创造者
赵亚溥常常思考:什么是好的教师?怎样才算是高明的教学?
“我仿佛听到,希尔伯特作为哈姆林彩衣人,所吹奏的来自远方的悠扬笛声,召唤着如此众多的像鼠一般的追随者和他一起跳进数学的深河徜徉。”他以数学家赫尔曼·外尔纪念恩师希尔伯特的这句话明志,希望做学生“悠扬笛声”的引路人。
在他看来,“教出的学生不是只能运用结论的人,而是学科的创造者,这才是好的老师、高明的教学”。赵亚溥试图将学生置于科学史的长河之中,讲述知识的源头,使他们开阔视野,敢于质疑,最终成为新知识、新理论的创造者。
赵亚溥不是只把自己当作“教书匠”,而是把自己定位为“培养杰出科学家”的教育者。为了更好地实现这一目标,他专程到莫斯科大学学习考察授课模式和课堂形式;与剑桥大学著名的科学家、教授探讨“如何给本科生上课”;借助前往法国参加学术会议的机会,专程到巴黎高等师范学院与数学和物理教授交流“教育教学理念”。
有激情的“赵爹”
有激情的“赵爹”,这是学生对赵亚溥的尊称。
课堂上的他能“一口气”讲两个小时,最后一分钟的气势依旧如刚上课的第一分钟;一个公式的推导密密麻麻写满整整10块黑板,写了擦、擦了写,每次上完课,头发、衣服上都落满了粉笔末……
对赵亚溥来说,给学生上课这件事儿“非常重要”,用他自己的话说,就是“很累,但我充满激情”,而这种激情除了用在教课上,还“释放”在为学生编写最富思想性的教材和参考书上。
今年5月,赵亚溥历时三年为本科生《力学》课量身打造的教材《力学讲义》终于印刷出版了。常常是一下课,解答完学生们的问题,他就立刻赶回位于中关村的办公室写教材,“刚推导完嘛,很兴奋,得趁热打铁”。
赵亚溥自我调侃道:“在写书之前,头发还是很多的。”熟悉他的人谈到这本书时也都说,“385页的内容,真是一夜一夜‘熬’出来的。”
最近一次记者联系赵亚溥时,他正在烟台参加招生宣传。他从招生办老师那里得知:部分家长从头一天晚上就开始彻夜排队,由于天气降温,有的学生和家长还披着被子,劝都劝不走。那一刻,赵亚溥满含热泪:“我还能说什么呢?只能用更大的激情上好每一节课,将这些苗子培养成才!”

\title{\bf  Announcement 409:  Various Publication Projects on the Division by Zero\\
(2018.1.29.)}

\maketitle
 The Institute of Reproducing Kernels is dealing with the theory of division by zero calculus and declares that the division by zero was discovered as $0/0=1/0=z/0=0$ in a natural sense on 2014.2.2. The result shows a new basic idea on the universe and space since Aristoteles (BC384 - BC322) and Euclid (BC 3 Century - ), and the division by zero is since Brahmagupta  (598 - 668 ?).
In particular,  Brahmagupta defined as $0/0=0$ in Brhmasphuasiddhnta (628), however, our world history stated that his definition $0/0=0$ is wrong over 1300 years, but, we showed that his definition is suitable.
 For the details, see the references and the site: http://okmr.yamatoblog.net/

We wrote two global book manuscripts \cite{s18} with 154 pages and \cite{so18} with many figures for some general people. Their main points are:

\begin{itemize}

\item The division by zero and division by zero calculus are new elementary and fundamental mathematics in the undergraduate level.

\item They introduce a new space   since Aristoteles (BC384 - BC322) and Euclid (BC 3 Century - ) with many exciting new phenomena and properties with general interest, not specialized and difficult topics. However, their properties are mysterious and very attractive.

\item  The contents are very elementary,  however  very exciting with general interest.

\item The contents give great impacts to our basic ideas on the universe and  human beings.

\end{itemize}

Meanwhile, the representations of the contents are very important and delicate with delicate feelings to the division by zero with a long and mysterious history. Therefore, we hope the representations of the division by zero as follows:

\begin{itemize}

\item

Various book publications by many native languages and with the author's idea and feelings.

\item

Some publications are like arts and some comic style books with pictures.

\item

Some T shirts design, some pictures, monument design may be considered.

\end{itemize}

The authors above may be expected to contribute to our culture,  education, common communications and enjoyments.
\medskip

For the people having the interest on the above projects, we will send our book sources with many figure files.

\medskip

 How will be our project introducing our new world since Euclid?

\medskip

Of course, as mathematicians we have to publish new books on

\medskip

Calculus,  Differential Equations and Complex Analysis, at least and soon, in order to {\bf correct them} in some complete and beautiful ways.

\medskip

Our topics will be interested in over 1000 millions people over the world on the world history.
