Differential geometry is all about constructing things which are independent of the representation

The risk in designing any personal knowledge system lies in the overemphasise of the acquisition system to the detriment of the review system. Acquisition can masquerade as work, but collecting without review is pseudo-work.

The glow in the centre of the k-space image represents the lower spatial frequencies, which contains the bulk of the image contrast information. As we move away from this central glow, the finer details and edges, representing the higher spatial frequencies

Linear algebra usually has two sides to explore: the algebraic interpretation and the geometric intuition. Usually the latter is much more useful to get a feel for things.
However, there’s a third way to think about the first moment, and it’s the one that I think is most useful for understanding moments generally: the first moment tells us how far away from the origin the center of mass is. I like this interpretation because it is analogous to a moment arm in mechanics, which is the length of an arm between an axis... See more
