## Summer Work

You may read or download your Summer Work assignment. You may also view Reflections on My Education by Dr. Rob. The summer reading and the example I give will hopefully put you in a reflective mood to start your own memoirs. (Notice that this directs to the same pages as for Physics 1.)
