START LEARNING LASER IN MORE DETAILS
A laser is a device that emits light through a process of LIGHT AMPLIFICATION based on the STIMULATED EMISSION of ELECTROMAGNETIC RADIATION. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation".
The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow.

ELECTROSTATICS INTRODUCTION COMPLETE OVERVIEW
Electrostatics is a branch of physics that studies electric charges at rest. Since classical physics, it has been known that some materials such as amber attract lightweight particles after rubbing.
Del, or nabla, is an operator used in mathematics, in particular in vector calculus, as a vector differential operator, usually represented by the nabla symbol ∇. When applied to a function defined on a one-dimensional domain, it denotes its standard derivative as defined in calculus.
