Finished chapter 1 of Purcell, woo? Need to do problems though. Also, did not like Eq. 39?
Read some of Ryder, that was good (~9:45)
(~10:20) Did some more Ryder. . .unhappy with something. Stuff that follows is okay, but I need to check what something means.
~4am Researching for essays…so much sigh.
