I created the mind map with FreeMind—free, open source software from SourceForge; and have continued to develop it with FreePlane—also available for free from SourceForge. The background photo in the penultimate slide, I took from my veranda on March 14, 2017.
If you have concerns or questions about mind-mapping tools; or suggestions of novel, possible, and practical uses for learning or teaching [with them]; please don't hesitate to spell them out in comments on this post.
