## Minutes

* Elliot:
* Notebook for Stix dispersion solver
* comparison of results with $\omega^2/k^2v_A^2$ plots in Bellan's paper
* Erik: only the cold plasma assumption is different? Pick the cold ion limit and show that the two approximately agree, pick the hot ion limit and show they disagree; if that's not right, make adjustments accordingly
* c.f. plot at the end of the Hollweg dispersion notebook
* Plan for next release in mid Sep to early October
* https://github.com/PlasmaPy/PlasmaPy/pull/1661 needs python version bump (release after ^)
* Erik: full annotations like `u.Quantity[u.m/u.s]` look ugly as heck
* ... or does it? Nope! Since we're EXPERIENCED PYTHON DEVELOPERS we (Erik) realized it's just `typing_extensions`
* ``Q["m/s"]``
* ``u.Quantity["length"] ``
* would have to go in Check decorator
* btw would be good to merge check_relativistic into check_units

* https://github.com/PlasmaPy/PlasmaPy/discussions/1687 basic outline for plasma class
* Proposal to change our license to BSD-3-Clause+-Lawyers
