Maxwell equations is the greatest formula in the 19th century, which not only represents the traditional physicists' painstaking pursuit of formula aesthetics, but also affects the physical and aesthetic taste of countless later generations.

Looking back at history, when Maxwell issued the famous "dynamic Theory of electromagnetic Fields" in 1864, he actually listed 20 formulas to summarize the previous physics achievements. We combined the component formulas into vectors and got eight formulas, that is,

The above symbols represent

Twenty years later, Heaviside rearranged the twenty formulas, got the familiar form, and named it the Maxwell equations:

Then take the curl from the left two curl formulas in the above formula, and get

Where ∇ E = 0, so the wave equation can be obtained.
