{title2=121.6 nm}
{title2=10.2e V}

<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>.

* backend:
  * <randyscotsmithey feathers-realworld-example-app> worked with <React> and <Vue.js>
  * the <React> setup failed as shown at: https://github.com/gothinkster/react-redux-realworld-example-app/issues/187
  * <gothinkster django-realworld-example-app>
  * the <Nest.js> failed on Ubuntu 20.10 as per https://github.com/lujakob/nestjs-realworld-example-app/issues/19
