This preference seems to depend a lot on where you come from. Having come from Scheme / Lisp (same as some of the original Julia developers AFAIK), I find I prefer the REPL in Emacs for coding. I do use Jupyter quite a bit for runnin

Came here to say this: my first thought was that this can provide a nice interface for implementing Radul & Sussman's propagator model https://dspace.mit.edu/handle/1721.1/44215

For anyone interested: the physical phenomenon is spin-orbit coupling. Here's a somewhat technical discussion of the classical version: https://mitpress-request.mit.edu/sites/default/files/titles/..

I like the friction of chalk-on-blackboard; somehow I write better with it than on white boards. For the same reason, I prefer pencil to pen on paper, and both to an Apple Pencil on an iPad (though the latter is what I mainly use these day

I have never used the old chalk, but the new ones are plenty good IMO, and certainly significantly better than any standard-issue chalk anywhere. Everyone I know who still has a blackboard has a private stash of Hagoromo in their office.

I followed the link for the article, but the photos are just stunning I thought. Anyone know how much post processing is typically done on this kind of (underwater) wildlife image?

I remember trying to grok Sussman's pattern matching code for 6.001. IIRC this was written in CPS or CPS-like way. It seemed very foreign at the time, but when I finally thought I got it, it made sense. I don't find search &amp

Cephalopods are protostomes ( https://en.wikipedia.org/wiki/Protostome ), vertebrates are deuterostomes ( https://en.wikipedia.org/wiki/Deuterostome ). I'd think with our current understanding o

Thank you for the very nice explanation!

Another issue of both practical and theoretical importance is whether these asymptoticaly-faster algorithms are numerically stable. Skimming the article very quickly (and not having looked at any original sources), this doesn't seem t

It makes me wish I had kept my SE/30.

Not arguing with your broader point, but the passage quoted above lists all Cell Press & Lancet journals. These would include, e.g., Cell, Neuron, etc., which are top-tier journals in their respective fields.

Interesting! The Beethoven recordings that I like best (e.g., Moonlight, Tempest, Pathetique) don't feature unusual interpretations; in fact they're by-the-book in a certain sense, which I really like. I don't have any of hi

I've been listening to Gould's Beethoven sonata recordings lately. I don't like all of them, and some of them I even find a little irritating. But there's something new and fresh in many of them (even the ones I ended

This book looks like it may be a nice complement to these CAT notes: https://www2.math.upenn.edu/~ghrist/notes.html (I haven't gone through either.)

As others have noted, it can be harder to move around academia than in industry. Your immediate community matters a lot more, whether you're a PhD student, a postdoc, or faculty. When things work it's great; when they don&#x27

Another extension is the ensemble Kalman filter ( https://en.wikipedia.org/wiki/Ensemble_Kalman_filter ), which can work well for certain kinds of nonlinear systems, and when it does it can be more robust than particle f

Also, libraries can and do exclude journals for cost reasons. My university is starting to do more and more of this. They haven't gotten rid of anything critical to what I do, yet, but there are certainly journals I don't have a

At least in my area of mathematics, journals still do some copy-editing, mostly to conform to journal style and fix obvious grammar / spelling mistakes. Journals do sometimes advertise, and that can be expensive. It's also one wa

I've never had the chance to see it, and I really would like to. I suppose when things return to "normal"...

I just got my copy off the shelf & will have to re-read it. Is there a production available online that someone would recommend?

That's indeed a neat property! Re: "no good algorithm for inverse Laplace" -- there are certainly reasonably good numerical algorithms based on evaluating contour integrals (see, e.g., https://en.wikipedia.org&#x

Of those three I was initially least interested in reading Anathem. Maybe as a result, I was most pleasantly surprised by it. Agree that none of these compare to the Baroque Cycle.

That's interesting. I haven't read Dodge. Thanks!

by kkylin 6y ago
Yeah, I kinda forced myself through that one. Not sure it was a good decision.

by kkylin 6y ago
Absolutely agree! And Beautiful Brain: The Drawings of Santiago Ramon y Cajal is still highly worth checking out.

I haven't been disappointed by the endings of his more recent novels: Cryptonomicon, Anathem, Seveneves. (I did not enjoy time spent on REAMDE, that being the only exception.)
