[Rockhounds] Near-Earth Supernovas and Mass extinctions ( Lecture video)

[J Bryan Kramer]

The first link, a video of the talk is rather interesting. If you are
familiar with the details of supernova mechanics you can skip forward
to about 40 mins or so for the more interesting material.

“The problem isn’t that Johnny can’t read. The problem isn’t even that
Johnny can’t think. The problem is that Johnny doesn’t know what
thinking is; he confuses it with feeling.”
