I have been reading Michael Pollan's book, How to Change Your Mind . In the first couple chapters, Pollan is trying to link some of the newer (1960s+) perceptions that we have about drug-induced mystical experiences, to those of earli

You don’t need integration to define expected value or covariance in the discrete case. TBH I’m not sure if you can get around integration in the general continuous case or not. If not, you could use some limiting argument to handle the mom

It does, my kid finished calculus-free high school physics last year.

by mturmon 3y ago
You can sidestep calculus by just using the discrete setting rather than a continuous one. If you want to introduce continuous distributions like the Gaussian one, you can just say "area under the curve" if you need to connect the

Reasonable point - in the case of parity, one bit of recurrent state avoids the combinatorial issues mentioned in OP (as OP more or less says in writing the finite state automaton). It's interesting to think about parity in relation to

Indeed, NeXTSTEP was purchased by Apple, as a part of NeXT Inc. NeXT Inc., in turn, was originally founded by some guy named Steve. So yeah, not exactly stolen.

I did not know that one! It's a more complex version of the well-known functional definition of the exponential function, i.e. the unique continuous function satisfying E(x) E(y) = E(x + y) and a normalization, E(1) = (whatever)

My problem and shame has been the false negatives I have. I meet people with great potential all the time - who have done more, or know more, or think more deeply about something than others. And it's apparent to me - they're goin

By now, it's well-known that HST was based on spy satellite designs via the mirror-making technology, as you say. See under "size and mass" at: https://en.wikipedia.org/wiki/KH-11_KENNEN According to tha

> previously the low-effort default option was great You mean incandescents? I disagree, their efficiency is terrible ("space heaters that happen to glow"). And their lifespan was artificially limited.
256.
by mturmon 4y ago
I fully agree, and would add that imposition of these artificial limits seems to be a fundamental side-effect of capitalism. "Good old-fashioned" incandescents were also subject to a multi-decade scam to limit their lifetime: htt

You often see these two concepts (target fixation and counter-steer) discussed in threads on steering. Not denying that target fixation is real and operative in some circumstances ... but counter-steer is even more "basic" in that

Interesting link. I've never experienced significant headache relief from acetaminophen/Tylenol, and it's nice to see some peer-reviewed results replicating my experience.

Here's one way to do this. I have used this method (directory mod-time triggering, let's say) for a simulation-summarizer which analyzes whatever pile of simulation-output-files happen to be in a given directory. If you run a new

This can be a very powerful idiom (basically, code generation at the shell prompt). It’s well suited to iterative composition of the commands: I’ll write the query/find part, and (with ctrl P) add the awk manipulations, and then pipe t

Yeah, it looks like it was "satellite data" and got cut off. OTOH, there's no end to the qualifiers. Some people might be disappointed that it's for Earth remote sensing data (as opposed to Mars). Some might be bothere

Yeah, I think citation without reading is pretty common. You find a lot of citations of Metropolis, Metropolis, Rosenbluth, and Teller’s paper on MCMC but I bet 1 in 10 have read it. Ulf Grenander’s massive book on Pattern Theory is another

I know something about SAR and InSAR because I use radar (Earth) remote sensing in my day job, and I have a signal processing background. But I’m not a serious radar expert. ISAR sounds like its operating principle is the same as the radar

I’d agree partway, and I appreciate the counterpoint, in that the delay coordinate is simple. But Doppler for a rotating, irregular asteroid is not simple. See Fig. 1 of the paper I linked for an example. It really is many-to-one. Delay-Dop

> ... the image be recovered out of Doppler and timing info... Yes, that's right: they are using doppler shift of the rotating asteroid, and the delay of the propagating signal, to form the "image". See my other comment ne
