About four months ago, a multi-week binge on papers, talks, books, and videos involving Seymour Papert, Alan Kay, Bret Victor, Mike Bostock, and Ken Perlin left me feeling inspired about education.¹ This website is the result of my well-meaning and naive zeal.

My hope is that the method of visual explication employed in this primer has made some difficult concepts a little less difficult to learn and think about. I’m relying on enthusiastic readers, students, and educators to set me straight if there are aspects of this text which are misleading.

If you’ve made it this far, I’d love to hear about your experience with this primer. Contact me on twitter if you have questions, comments, recommendations, or complaints about the content.

There’s so much more to signal processing than is covered in this primer. In the future I’d like to attempt some visual explication of topics like convolution, autocorrelation, filtering, resampling, and the phase vocoder. If you have any other ideas or specific wishes, feel free to contact me.
