my exploration of relativity followed by first reading various books which failed to explain to me how relativity worked but built a strong feel of how one can think about it. after which i decided to take the mathematical way of understanding it for which i am going on with the prof susskind's lecture

a quick doubt in it , in allmost all the first few parts of the series he says that tensor is a quantity that remains unchanged in different coordinates (is it ?) but derives the equation relating metric tensor in one frame and another coordinate frame. my understanding of tensor isn't that much strong.

PS: i think the first statement i made is wrong, as far as i conceive tensors i guess they are not constant for all frames.( as vector is a scalar and even it does change when moving from one flat coordinate to another curved surface coordinate (again does it ?) )
