differential geometry.... I am constantly being told that this is important stuff for undergradautes to know about and it is taught by the end of the secon year....however, I am not going to be seeing ANY of this stuff at all during undergraduate school. And there isn't even a class offered in differential geometry. However, I was told my the mcs chair that he would set up a directed study in differential geometry since many other students are very interested in it. Is this differential geometry THAT imporant in a ugrad physics curriculum, and if so, why doesn't my school require it???
