To run the demos locally, tested on <Ubuntu 22.10>:
``
git clone https://github.com/liabru/matter-js
cd matter-js
git checkout 0.19.0
npm install
npm run dev
``
and this opens up the demos on the browser.

This is where <Ciro Santilli> stored his code since he started coding nonstop in 2013.

He <closed source is less bad on online services>[does not like the closed source aspect of it], but hey, there are more important things to worry about, the network effect is just too strong.

<equation Hydrogen spectral series mnemonic> gives for example from <principal quantum number> 1 to 2 a difference:
$$
E_n = -13.6eV\left[\frac{1}{2^2} - \frac{1}{1^2}\right] = 10.2 eV
$$
which with <Planck-Einstein relation> gives about 121.6 <nm> ($2.47 \times 10^15$ <Hz>), which is a reasonable match with the value of 121.567... from the <NIST Atomic Spectra Database>.
