Fermi Doesn't Blow up Chicago II

Since posting a TikTok on this question, I've received a bunch of responses - thanks to everyone who sent ideas my way!

I've reviewed all the comments and responses on my original TikTok and blog, and maybe I'm just being hard headed here - but I still don't get it. I have learned a bunch more though, and believe I have a higher quality set of questions to ask - which I've outlined in this colab notebook.
