There is an interesting music video[1] by Nigel Stanford featuring Chladni plates among other cool phenomena. That's how I first learned about Chladni plates<p>[1] <a href="https://vimeo.com/111593305" rel="nofollow">https://vimeo.com/111593305</a>
These figures could be the universal pictoral symbols for numbers. I especially like the triangle figures since the triangle is the 2D simplex.<p><a href="https://domodernlife.files.wordpress.com/2014/07/nodal-lines.jpg" rel="nofollow">https://domodernlife.files.wordpress.com/2014/07/nodal-lines...</a>
> When Chladni showed the technique in Paris, Napoleon set a prize for the best mathematical explanation. Sophie Germain's answer, although rejected due to flaws, was the only entry with the correct approach.<p>Science and Mathematics visibly take time and effort not a contest and some goodwill.
which programming framework would best allow the coding of an app to generate Chladni figures on an arbitrarily user drawn shape? And perhaps with a knob to allow frequency modulation. Or perhaps two or three knobs to allow visualization of harmonics. Would this allow a graphical solution to Schrodinger's equations for one, two, three electron models?
