What I find most amazing in the article is the technology of radiocarbon dating individual year rings in a piece of wood, correlate that to known cosmic radiation events, and get the precise year when the tree was felled.

The science that enables that is described in this paper: https://www.nature.com/articles/ncomms2783 https://www.nature.com/articles/ncomms2783
