  1. I’d have loved to have you as my professor 50 years ago!
    It would have saved me a lot of time and headaches!
    I also love your explanation of ‘The Circle of Fifth’.
    Simply outstanding!

    • Wow. Thank you. I’m just trying to explain it in the way I wish it had been explained to me. I have always found maths a very difficult language to understand. I need the graphical demonstrations to help me understand the equations.

  2. If it were my will, I would forbid teaching people who do not know how to explain the Euler formula as you did. Thank you Mark.

  3. Learning fourier transfrom with visual makes perfetct combination. Thank you for helping me alot understanding this.
    i couldn’t find the video explaination of DTFT.

    • Thanks for your kind words. As of the time of the writing of this reply, there isn’t one yet. I’m working on turning all the remaining blog posts in to videos as we speak.
