啱，瞓了，聽日先講，多謝咁多CHING陪我傾訴，留contact開wtsapp group都得架
想知究竟讀數𠴱啲之後做咩
肯去教書其實唔會餓死嘅
小弟都做緊補習狗

a functor is just a mapping from one category to another that preserve morphism composition and id
an endofunctor is just a functor from a category to itself
the category of endofunctor is just a category which objects are endofunctors and morphisms are natural transformation and have a monoidal structure given by functor composition and id
a monoid object in a monoidal category is just an object with a multiplication and id satisfying some fancy commutative diagrams (which is just correspond to associativity and id)
So, a monad is just a monoid in the category of endofunctors, what's the problem?

升yr3 了但下sem先讀2050
好似遲好多咁

冋果諗住就咁grad就算其實無乜野
係諗住就咁grad算但yr1hea得太緊要，驚2nd low都保唔住
真係要落力讀了

今年engine grad
自問對數學好有興趣, 想讀返個master, 是否不智
