you are not smarter than blizzard ' s devs <| sep |> Over 10 hours old but I didn ' t see it posted here . No idea if it is accurate . Is there an official ceasefire in place there , or is it an unofficial ceasefire ? EDITAnother tweet about this <| sep |> I would have loved this as a kid . I ' ll echo what uLovehat said , I always learned more by seeing something in pictures or in person than having someone talk at me about it . <| sep |> While crushing cars . <| sep |> It ' ll last till Nov 29 . So it means no extra daily deals ? <| sep |> I see a connection as a generalized derivative for vectorfields . So if we want to look at $ nablaXY at a point p , we take a curve C e , e M such that C 0 p and C ' 0 X . Then when you look at the change of Y on that piece of curve and that will be your connection , intuitively ofcourse . Notice the similarities here with the standard notion of derivatives . As for connections on immersed submanifolds , your connection is determined by your induced metric on your submanifold . So you can use the same method as you would define a connection on an arbitrary Riemannian manifold . However I don ' t know the specifics behind regular submanifolds . I ' ll leave the following link which also gives intuition about Lie brackets and Curvature . This maybe usefull later on in your reading j o u r n e y t h e r e s i m p l e e x a m p l e s o f r i e m a n n i a n m a n i f o l d s w ithzerocurvatureandnonzer
