Ggeordief replied to the thread Undergrad How Is Intrinsic Curvature Measured in Higher Dimensions Like 4D Spacetime?.So I take your (and,presumably eveyone else's) word that the tangent planes of a sphere (and presumably of any "uneven sphere" ) can be...

Ggeordief posted the thread Undergrad How Is Intrinsic Curvature Measured in Higher Dimensions Like 4D Spacetime? in Special and General Relativity.The intrinsic curvature of a 2d sphere is measured (as far as I can tell) by the means of its tangent planes that lie in the 3d...
