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 equation, which is the key to quantum physics. In 2021, physicists published a paper claiming that you can’t entirely get rid of complex numbers in quantum physics, but two teams of physicists recently published papers disputing that claim. Let’s take a look.
