I think the accusation implies Kimi has gained time travel capability (distilled from fable probably) to have enough time distilling fable. Given they can travel time now, I think it is fair to call them a threat to national security.
This also functions as a light meter for analog photographing. There are light meter apps on smart phones, but it is fun to measure through a lighter/simpler equipment.
I’d like to recommend Prof Chern’s course on Discrete Differential Geometry https://cseweb.ucsd.edu/~alchern/teaching/cse270_wi24/. The lecture slide on Exterior Calculus includes many good illustrations of differential forms, and there are more cool figures on related topics. There is also a pdf textbook neatly formatted if you want to dive deeper.
