本文为纪念牛顿的《自然哲学的数学原理》一书发表三百周年而作。近代物理学的发展确立起三个理论——量子论、狭义相对论和广义相对论,它们都是以坚实的物理实验为依据的。众所周知,量子论和相对论在基本概念上有着深刻的内在矛盾,因此它们的统一导致普朗克空一时概念的产生。普朗克空-时涉及的范围极小,时间极短,能区极高,尽管至今无法在实验上加以证实,伹物理学的发展至少提出了这一问题,而这正是牛顿指出的前进之路。
This article commemorates Newton's 300th Anniversary of the Mathematical Principles of Natural Philosophy. The development of modern physics has established three theories - the quantum theory, the special theory of relativity and the general theory of relativity, all based on solid physics experiments. It is well-known that quantum theory and relativity have profound inherent contradictions in their basic concepts. Therefore, their unification leads to the emergence of Planck's tentative concept. Planck's space-time range is minimal, time is extremely short, and energy can be extremely high. Although it has so far failed to be proved experimentally, the development of physics has raised at least this issue, and this is exactly what Newton pointed out the road.
