I noticed this TED talk
on the history of the cosmos from the big bang to the present, emphasizing 8 threshold events.
This has turned into a project to introduce a new course to educate folks on Big History and its importance for our surviving the challenges we currently face.

I found it interesting too from the SFX projet approach: big ideas into important projects.
