I much enjoyed Kalid Azads Interactive Guide to Fourier Transform article on [ and was much impressed he mentioned my animated sine demo, which he extended upon in wonderful ways. ]

With recent javascript and web 2D/3D, I think we’re at the cusp of a kind of interactive learning renaissance.. because Math concepts can be made really physical, tactile and intuitive :  Show-me-how-it-works + let-me-drive beats verbose-monologue every time.

I wanted to mention another variant of the animated sine demo, where you can add a second circle and slide back and forth to see the first 2 terms of a Fourier series.


It seems like a gentle intro that would get young people thinking..’hmm, what if I add another circle… and how big should that circle be…’.

Obligatory Tolkien quote : “It’s a dangerous business, Frodo, going out of your door. You step into the Road, and if you don’t keep your feet, there is no knowing where you might be swept…”
