EA introduction course and YouTube playlists

Hi guys!

We are getting ready to accept new student members to our workgroups at EA NTNU this fall, and we want to make a course program for our new members to get them up to speed on central ideas, organisations and concepts within EA. The idea is to meet once a week for three weeks, discussing and working on central topics for about two hours. We are planning to make YouTube playlists introducing the ideas, and that the new members will watch these playlists before each gathering (as well as reading essays in the EA Handbook). We have spent some time brainstorming ideas on central topics to include in the course, but it would be nice to get a feel for what other people view as important to counter any group thinking we might have.

These are the topics we have thought about (rot13):

* RN uvfgbel naq vagreangvbany bireivrj
* Engvbanyvgl (Pbzzba guvaxvat reebef, fgngvfgvpny naq rpbabzl pbaprcgf, naq ybtvpny snyynpvrf)
* Pnerre gvcf (80x)
* Tybony cbiregl naq rinyhngvba (TJ naq gurve erpbzzraqrq betf)
* Rkvfgragvny evfx
* Navzny jrysner
* Zrgn-RN (inyhrq pevgvpvfz, tebjgu fgengrtl naq pbzzba zvfpbaprcgvbaf)

For the long run, we are thinking of expanding the YouTube playlists idea to include deeper introductions to more complex ideas, discussions and concepts (Think Vsauce leanbacks, if you have heard of them), to make our YouTube channel a HQ for people to explore ideas we care about. The videos we currently have range from very EA related (like this one) to more general (like this one).
If you have examples of good videos we might have overlooked they are much appreciated!

tl;dr:
1) What concepts, ideas and organisations are essential to introduce to members who are new to EA?
2) Have you come across good online content (articles and videos, preferably on YouTube) explaining central EA concepts, ideas or organisations.
