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
> 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.
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?
On-Topic: Anything that good hackers would find interesting. That includes more than hacking and startups. If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.
If you don't find it interesting, don't read it, and upvote stories you do find interesting. Don't complain about other people's taste. Do you think everyone is always fascinating by everything on the front page? Wrong.
