Perhaps most importantly of all, James Clerk Maxwell, who is also considered to have brought about the second great unification of Physics (the first being accredited to Newton) with his classical electromagnetic theory.

这三位是现代历史中最著名的理论数学家。也许最重要的还有詹姆士麦克斯韦,他的经典电磁理论通常被认为带来了物理学的第二次大一统(第一次是牛顿)。

我们关于外间世界的知识

This billiard-ball view of matter dominated the imagination of physicists until quite modern times, until, in fact, it was replaced by the electromagnetic theory, which in its turn is developing into a new atomism.

这种对物质的台球观点一直主导着物理学家的想象力,直到相当近代,直到事实上,它被电磁理论所取代,而电磁理论又发展成为一种新的原子论。

马克士威方程组 Maxwell's equations

(重定向自Electromagnetic theory)
詹姆斯·马克士威
高斯磁定律: 磁场线从来没有初始点也没有终止点,但是形成循环或延伸到无穷远,如图这里因为电流环与磁场。
左半图:一群微观的电偶极子的共同作用,就好像以宏观距离分开,分别位于图上方和图下方的一对带电薄面的有效作用(请注意,这些带电表面所生成的电场,并不是原本造成电偶极子排列的电场,而是等价于这电偶极子排列的宏观表现出的电场)。右半图:一群微观的电流回路的共同作用,就好像一个宏观的电流回路的有效作用。假设电流回路均匀分布,则所有位于内部的电流回路的贡献都会互相抵销;但是,位于边界的电流回路不会全部地抵销,因而形成宏观的电流回路。

马克士威方程组英语:Maxwell's equations),是英国物理学家詹姆斯·马克士威在19世纪创建的一组描述电场、磁场与电荷密度、电流密度之间关系的偏微分方程。它由四个方程序组成:描述电荷如何产生电场的高斯定律、论述磁单极子不存在的高斯磁定律、描述电流和时变电场怎样产生磁场的马克士威-安培定律、描述时变磁场如何产生电场的法拉第感应定律。

从马克士威方程组,可以推论出光波是电磁波。马克士威方程组和劳仑兹力方程序是经典电磁学的基础方程序。从这些基础方程序的相关理论,发展出现代的电力科技与电子科技。

Maxwell's equations 马克士威方程组

(重定向自Electromagnetic theory)
Maxwell's equations (mid-left) as featured on a monument in front of Warsaw University's Centre of New Technologies
Closed volume Ω and its boundary ∂Ω, enclosing a source (+) and sink (−) of a vector field F. Here, F could be the E field with source electric charges, but not the B field which has no magnetic charges as shown. The outward unit normal is n.
Open surface Σ and boundary ∂Σ. F could be the E or B fields. Again, n is the unit normal. (The curl of a vector field doesn't literally look like the
Gauss's law for magnetism: magnetic field lines never begin nor end but form loops or extend to infinity as shown here with the magnetic field due to a ring of current.

Maxwell's equations are a set of partial differential equations that, together with the Lorentz force law, form the foundation of classical electrodynamics, classical optics, and electric circuits. These fields in turn underlie modern electrical and communications technologies. Maxwell's equations describe how electric and magnetic fields are generated and altered by each other and by charges and currents. They are named after the physicist and mathematician James Clerk Maxwell, who published an early form of those equations between 1861 and 1862.
