Jeremy & Isaac are done!

Session 0 is a special pre-class for returning students to give them a chance to pick up where they left off last year, and in some cases to finish up. And that is just what the father-son team of Jeremy & Isaac did, putting the final figure on their very well done mirror.

Cool Stuff

Some other cool things went on this day. Tommy G made some tube out of PVC pipe to illustrate the field of view of different focal ratios, and Wayne worked with the grinding machine.
