#TIL #arXiv now supports linking code and data. https://medium.com/paperswithcode/datasets-on-arxiv-1a5a8f7bd104
#TIL about "Megadiverse countries".
I am not sure how comparable these countries are in ethnic- and bio-diversity.
A forgotten(?) scientist
For a contribution of this magnitude, used in compression like JPEG and MPEG and in computational sciences like CFD even today, I don't see any awards or accolades.
#TIL how Fourier transforms and #pseudospectral methods are intimately related to #FEM. What was missing from the picture is how a tool for numerical integration could be used for numerical differentiation.
If you think about it, Fourier transforms are also expressed as integration over an interval in space. When you differentiate a function it only affects the basis. For example:
exp(ikx) -> ik * exp(ikx)

#TIL about Aristotle's wheel paradox. Simple and mind-boggling at the same time.
#TIL while listening to a class for K-2 kids that monkeys are different from lemurs (prosimians) and apes (gorillas, chimpanzees).
