This ones for Mike.

raised to the power of x multiplied by s, i (the square root of -1) and pi.

You know that feeling when you're running a marathon and you get to the 18-mile mark and you 'hit the wall' and just want to pack it all up, quit and go home? That's the way I felt in high school when we hit the square root of minus 1.

I liked the reference to how "your ear performs Fourier transforms all the time". Clever things, these brains. As long as you keep them away from the square root of minus 1.

Being the nosy fella that I am, I eavesdropped and read it, sorry but I enjoyed it too! Nicely written in layman's terms. Although, that part Andy picks out was completely unnecessary to spell out for the sake of it. I also recalled my maths teacher befuddling us with the imaginary i symbol.

I remember using Fourier transforms during my degree and my programming projects which included satellite array communications which naturally led me to become a burger King sandwich maker but sadly couldnt find a way to put fourier to use while prepping the tomoatoes and so I had forgotten its power until now.

Thanks for the reminder article, Brian.

The post was for everyone the reference to be for Mike was ironic. I have to say I like i , it is so very elegant.
