The title says it all. This episode is about quasars. I return to my original “training” in astrophysics in order to correct some misconceptions that may have crept into my video titled “The Nexus” here: https://www.youtube.com/watch?v=zpTxBkmr4LE 
This episode covers three basic things:
The history of the discovery of quasars
The physics of quasars
Varieties of quasars
As with episodes of this kind, it is "image intensive" and although I hope listeners of the audio only will find value - there might be something missed without the images.
This episode is also in recognition of the long term work of author Danny Frederick's contribution to the promotion of Popperian epistemology. May Danny be remembered as a philosopher of deep insight into epistemology and a critically rational worldview.
