Pretty solid explanation of the Yoneda lemma: http://blog.sigfpe.com/2006/11/yoneda-lemma.html
(I don't understand the lemma myself, but since I'm in a category theory class, I'll have to at some point)
cc @sl2c @fabianhjr @otini, but I don't know any other #categorytheory people here sadly
@sl2c @otini @danielhglus the hard part is the proof / commutative diagrams but those are going to be your bread and butter for a Category course. If you are struggling don't worry, just keep practicing and you are going to get better. :3
@danielhglus @otini @sl2c hey, Yonneda's Lemma is simple. You can embed any (locally small) category into the Set Category.
It is very similar to Cayley in groups (You can embed any group into a permutation group Sn)
