| Nowadays, imaginary numbers are an essential tool. Combinations of real and imaginary numbers like, for example, $ 4+3i $, are known as [[basic_tools:complex_analysis|complex numbers]]. Complex numbers are the standard number system that physicists use. | Nowadays, imaginary numbers are an essential tool.

| - | Imaginary numbers are essential in modern theories of physics like [[theories:quantum_mechanics:canonical_quantum_mechanics|quantum mechanics]] and [[theories:quantum_field_theory|quantum field theory]]. In these theories, we describe a physical system using complex functions, which means functions that contain combinations of imaginary numbers as arguments. | + | Imaginary numbers are essential in modern theories of physics like [[theories:quantum_mechanics:canonical|quantum mechanics]] and [[theories:quantum_field_theory:canonical|quantum field theory]].
