Have been to Chernobyl twice as a journalist and can tell you, this was very well written.
Yes, I agree it was very well written.
Seeing the footage of detonations can be interesting but it’s nice to have the physics of the explosion spelled out concisely.
Here's a link to some fairly recent pictures of the abandoned city around Chernobyl. You may have already viewed these, maybe not. The pictures of the hastily evacuated schools are quite sad.
There are some comments at the end of the post that are profane and unnecessary so ignore those.
