Chladni Figures

There is an interesting music video[1] by Nigel Stanford featuring Chladni plates among other cool phenomena. That&#x27;s how I first learned about Chladni plates<p>[1] <a href="https:&#x2F;&#x2F;vimeo.com&#x2F;111593305" rel="nofollow">https:&#x2F;&#x2F;vimeo.com&#x2F;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:&#x2F;&#x2F;domodernlife.files.wordpress.com&#x2F;2014&#x2F;07&#x2F;nodal-lines.jpg" rel="nofollow">https:&#x2F;&#x2F;domodernlife.files.wordpress.com&#x2F;2014&#x2F;07&#x2F;nodal-lines...</a>

Also known as vibration node patterns or modal patterns. Useful to find resonances.

&gt; When Chladni showed the technique in Paris, Napoleon set a prize for the best mathematical explanation. Sophie Germain&#x27;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&#x27;s equations for one, two, three electron models?

What&#x27;s with the habit people have of posting random things they just discovered and found interesting here. This isn&#x27;t news.
