This is my attempt to explain Imaginary and Complex Numbers by using the idea of rotations - it is supposed to be accessible to anyone wanting to discover what Imaginary numbers actually mean, without going deeply into any algebra.

This is my first video, so it's not perfect - in particular, my laptop mic is pretty dreadful, and the pace of the video does go a bit fast in places - it might well be necessary to pause/rewind to be able to absorb everything!

I hope you enjoy it, and please give me any feedback/ask any questions below!

EDIT: Since making this video, some people have pointed me to: http://betterexplained.com/articles/a-visual-intuitive-guide-to-imaginary-num... - it seems to explain imaginary/complex numbers in a very similar (and perhaps clearer!) way - so give it a look!

  • Thanks man. More videos please!

  • @FullWaveElectronics - I'm glad everyone likes it so far! I'm rather busy at the moment, but I might try and make another one over the Christmas period. Any topics in particular you'd like me to have a look at? Maybe more complex numbers, or some other part of maths completely?
