## Minutes

* Discussion about ZenHub
* We're using ZenHub to try to keep organized
* Does not appear we can have a public read-only view of a ZenHub workspace...arg
* units notebook
* Link to it from the first steps section of docs
* see issue [1400](https://github.com/PlasmaPy/PlasmaPy/issues/1400)
* Contents section (manually create; don't nest sections)
* fit functions notebook
* Break up the stuff into discrete sections
* Change flow from stream of thought to teaching
* Possible sections
* Unit basics
* basic principles
* no reference to plasmapy
* how to create a variable
* compound units
* Astropy Quantity is a subclass of numpy arrays
* Converting units
* basic km -> m e.g.
* using equivalencies
* Stripping units (i.e. `.value`)
* possibly stripping value `.unit`
* this is just a `numpy` scalar or array
* How are units used in PlasmaPy
* Advanced Topics
* What are Physical Types
* Unit math is slow!!!!!!!!
* Optimizing ← linking to `astropy.units` section
* Should link to astropy.units page not the module
* page link: https://docs.astropy.org/en/stable/units/index.html
* Cold plasma wave notebook
* Revamping it
* Still needs some discussion of the physics
* Look at Appendix B of Chen textbook for discussion on plasma waves
* Tien is potentially interested in adding a discussion of physics
* Should talk about polarizations for discussion of physics as well
