english: In the 19th century, Maxwell figured out that you can't explain electromagnetic phenomena in terms of the existing fundamentals — space, time, mass, Newton's laws — so he postulated fundamental laws of electromagnetism and postulated electric charge as a fundamental element that those laws govern.
non_english: V devetnajstem stoletju je Maxwell ugotovil, da ne morete razložiti elektromagnetnih pojavov z obstoječimi osnovami - prostor, čas, masa, Newtonovi zakoni - zato je osnoval temeljne zakone elektromagnetizma in postavil električni naboj kot temeljni element, ki mu ti zakoni vladajo.
