> boil down to the convolution of the signal with the impulse response of the filter Not to be "that guy" but any linear, translation-invariant operator can be written that way. This is the essence of harmonic analysis.

And my original "joke" is that the Schrodinger operator is unitary on L2 spaces (which is like a mathematical statement of conservation of "energy"), so if we're throwing out unitarity then I may as well throw out m

This sounds more like a critique of capitalism than anything. What I find absurd is the re-badging of appliances. A clothes dryer or a gas furnace is a very simple device. So simple, in fact, that you will find the same control board inside

I remember an intermediate OO class in Java 20 years ago... the existence of the El Camino was proof of the terribleness of both multiple inheritance and car analogies.

My (entirely uninformed… though I am a “doctor” har har) theory is that some sort of compression occurs in the brain. I also wrote out the answers to my flash cards by hand. I feel like these actions accelerate the compression process. If i

I was anti-memorization until I went back to graduate school for mathematics. I had forgotten (or never learned) a lot of things needed to pass qualifying exams. At some point I ran across the spaced repetition idea (maybe from the Wired Su

On one hand, named varieties are propagated via cloning (cuttings, tip rooting, air layering, tissue cultures, etc.) On the other hand, new fruit varieties are bred all the time. Human breeding programs can produce huge variations in a few

To piggyback: most berries, and fruits in general, are grown from clones.

Piggy backing here... but this dimension-reduction or system-identification stuff always reminds me of Takens' theorem [0]. He even did some neural network stuff back in the "dark ages" of the topic [1]. [0] https:/&#x2

Yeah, the Fourier transform diagonalizes differentiation. Or in other words "differentiation is a Fourier multiplier". Integration is like a low-pass filter (you divide by the amplitude of a component by its frequency and so highe

I was joking about making me feel bad. What you said is the reason I only consciously watch one or two series per year. Many of them look great, but few hold my interest.
