天津师范大学物理系钱时惕同志对物理教学1958年11月号发表的“谈谈动量和动能”一文提出不同的意见.对这些基本概念展开有益的讨论,无论从那一个角度看,都是有重要意义的. 首先我想说明一下我写那篇稿子的动机.自从党中央提出理论必须联系实际的指示,我深深感觉到以往脱离实际的严重.关于基本概念的教学,是否也应该与实际,尤其是生产实际联系呢?那篇稿子在第六节“主要问题”中就是从这个角度提出的.是否有教条主义,还希望读者尤其是钱时惕同志提出批评. 我那篇稿子中关于从时间过程和空间过程看力的作用那些话是在第三节“速度的一次方二次方问题”中提到的,而这是和第二节“传递问题”并列的,企图说明仅仅从这种角度去考虑问题,都不是主要的(见该稿第六节末句).第四节“究竟那一个是主要问
Comrade Qian Shiyi of the Department of Physics of Tianjin Normal University put forward different opinions on the article “Talking about momentum and kinetic energy” published in the November 1958 issue of Physical Education. From these perspectives, it is useful to discuss these basic concepts. All are important. First of all, I want to explain the motive of my writing. Since the Party Central Committee put forward the theory that the theory must be linked to practical instructions, I deeply feel that the past has been severe from reality. The teaching of basic concepts is also Should it be related to reality, especially production? The article was raised from this point of view in Section VI ”Main Problems“. Whether there is dogmatism or not, and also hopes that readers, especially Qian Shangyu, will criticize me. The words in the manuscript about the role of force from the time process and the spatial process are mentioned in the third section ”speed quadratic square problem“, and this is the second quarter ”transfer problem “Paratactic, attempting to explain that considering the issue from this perspective alone is not the main one (see the last sentence of section VI of the draft). Section IV ”What is the main question?
