论文摘要
通过认识到四力的最简单形式确实是可行的，可以整洁地提出电磁场的概念。我们表明，麦克斯韦的方程式几乎完全源于时空的特性，尤其是由于我们的世界具有d = 4的事实。它们的完整重建需要三个额外的假设，这些假设似乎与几何学离婚了，但实际上，可能与空间时期的属性有很大关系。
The concept of electromagnetic field can be neatly formulated by recognizing that the simplest form of the four-force is indeed feasible. We show that Maxwell's equations almost entirely stem from the properties of spacetime, notably from the fact that our world has dimension d = 4. Their complete reconstruction requires three additional assumptions which are seemingly divorced from geometry, but, actually, may have much to do with the spacetime properties.
