Welch Labs has a wonderful series on youtube on imaginary numbers, "Imaginary Numbers Are Real": https://www.youtube.com/watch?v=T647CGsuOVU https://www.youtube.com/watch?v=T647CGsuOVU I like to tell my kids that imaginary numbers aren't really imaginary .. that in many ways they're more real than the Reals.
