本期刊出林磊老师的文章,看似“超纲”,实际上仍是常识.爱因斯坦相对论已经科学地论证我们生活的空间是四维空间.由直观的三维空间想象抽象的四维时空,当然是“空间想象能力”的组成部分.构造一个用中学数学知识可
In this issue of the article by Professor Lin Lei, it seems that “super-outline” is still common sense in fact.Einstein’s theory of relativity has proved that the space of our life is a four-dimensional space scientifically.From the visual three-dimensional space, we abstract the abstract four-dimensional space-time Is an integral part of “spatial imagination.” Constructing a mathematical knowledge of middle school can be
