Journal Club

The primary goal is: to fill in gaps in knowledge of nuclear physics matters to develop group members into more well-rounded nuclear physicists.
The parallel goal is: to paint a picture regarding modern perspectives, outlooks, and approaches to answering fundamental questions in nuclear physics.
This means the fundamentals will still be covered but the club will approach topics in 2-3 meeting modules that will each build towards an interesting recent paper.
