Ah ok . I ' m currently taking an intermediate mechanics class and our text book mentions lagrangians but we haven ' t learned about them yet . I imagine the class you ' re talking about is sometime after intermediate mech then ? I ' m a sophomore and most people in my class are sophomores or juniors . We use Morin . <| sep |> Despite being a 21 year old male I still don ' t feel ready to be in a relationship I ' m still trying to learn to love myself . <| sep |> Factionalism isn ' t even why it ' s terrible , though obviously it ' s made the experience a lot worse in some unis from what I can tell , primarily the posher , most elite universities full of upper middle class kids desperately embarrassed about their privilege are most prone to that kind of far left radicalism . Compare to the 80 s when more plebbish unis like Red Essex were centres of Trot activity . . LS is just a bad organisation , even by the standards of the Labour Party .
