NYAS:Quark-GluonPlasma9903
I attended this session altho ( and because ) my foundation in physics is not what I wish . Bizarrely I ended up never taking physics in College despite it being the study of my life thru
HighSchool . On the other hand , I was interested to see to what extent the Math , and some of the particular conceptions I learned in my pursuit of an understanding of consciousness also underlay this particle stuff . I expected a bunch of Group Theory , but found instead most interesting issues of relativistic metrics and volume .
