I can do the math, I know about Euler’s formula, etc etc. But I am wondering if there is anything written that can help the reader intuitively grasp what kind of transformation “raising to a complex power” represents. Google turns up articles that just focus on how to do the math with symbols. I’m hoping to also know of a more intuitive way to talk about it.
For a visualization, you might find one on YouTube. Channels to try are 3blue1brown and mathologer. When you bring up one of their videos, also check the related videos that come up.
For those of us who are fortunate enough to work in one dimension, “raising to a complex power” is the same as “rotating through the imaginary dimension”. The real part of the complex gives you a magnitude, the imaginary part gives you an angle of rotation. You can picture the value advancing along a screw thread (with a zero internal radius) as the “power” is increased.
