Many thanks :)

Very nice explanation. I have a doubt at 5:38 . Why 2 before "sin theta/2"

Great lecture, sir, is there any lectures for pure twist GBs? Following what you said in this lecture, pure twist GBs are formed via screw dislocations. I want to know if GNDs can be subdivided into edge and screw dislocations? If so, how can we divide them? And is there any lecture talking about Nye's dislocation tensor?
