If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...

Mathematicians were disturbed, centuries ago, to find that calculating the properties of certain curves demanded the seemingly impossible: numbers that, when multiplied by themselves, turn negative.

(via Sabine Hossenfelder) Complex numbers are created when you add a real number and an imaginary number (like “i”). These numbers are used throughout math and physics, notably in the Schrödinger ...
