... order. We may split it arbitrarily into space and time, just as we can split the order of space into length, breadth and thickness. But space without time is as incomplete as a surface without thickness. Math. ... perceptual space and time is the same as the measured space and time, which is the subject- matter of natural geometry. In other respects he may not be so im...

... smooth space is called a manifold and where dx i forms a space, ∂/∂x i forms the corresponding ’dual’ space [2]. The dual of the dual space is just the original space dx i . Contravariant and covariant ... vectors are the dual of each other. Other examples of dual spaces are row and column matrices (xy) and  x y  and the kets <a| and bras |a>used in quantum mechan...
