Amazingly it's possible to tell exactly which year a tree was cut a thousand years ago.

1. There's a radiation mark 993 CE. (solar storm)

2. From that mark you count the rings until the edge of the log (the waney edge)

@JohanEmpa This really is mind-boggling! This clearly illustrates the falsity of the notion that the past is "lost forever" and thus only the present exists.

@JohanEmpa - Dendrochronology is a bit more than that, but yes, cool stuff. 😀

@JohanEmpa I was amazed by this when I saw it today. Can't wait for more now!
