I think your 3. and 4. are phrased a bit dismissively, though I don't entirely disagree. Not every workload in scientific computing maps cleanly into the GPGPU paradigm. Though that's not really a compelling reason to use Fortran

Usually you can trigger the electromagnetic sensor if you ride over the edge of it; there's usually a visible seam in the pavement. You want to ride along the edge of the loop.

Sure, but do the fixed costs really justify the current pricing? The last paper I submitted, the gold open access fee was $3k... Forget it, we just put the preprint on arXiv, which has no problem hosting versioned preprints at no cost to th

Moral/ethical issues of piracy aside, your final point of musicians earning a living just isn't a good analogy for academic publishing. None of the traditional or open access fees goes to the authors, so sci-hub or not, it makes n

Why should it take decades? I think you're conflating the UI issues with pedagogy and teaching-oriented publishing. GPs point seems to be that we already have the tools we need to start webifying the academic literature. There's n

Ok, I can see it from that perspective -- we have similar financial aid limits in the U.S. I still think it's a choice, even if it's one that's structurally difficult for many people to make. However, this is mostly orthogona

Ok, that's a bit different than how I read your earlier post, I thought you were saying that parents/relatives should be entitled to that info solely on the basis of footing the bill.

I disagree with you. It's your choice to engage financially with the university, and you should do so knowing that if you want to know how it's going, you need to talk to the student, not the university -- we have laws like FERPA

Most engineering programs do have at least one full semester of numerical methods, even if in practice most engineers use matlab, scipy, abaqus etc...

So don't distribute the actual papers? Even a complete citation graph with basic info (title, authors, abstract, doi) and a link to the publisher's canonical version would be a very useful tool.

I agree with you that having all cyclists wear helmets wouldn't strictly increase overall safety (maybe people will switch to driving...), but I think you're discounting the utility of helmets even where collisions with motorized

TEM really isn't the right tool for reversing large integrated circuits. The sample prep is too finicky and involves slicing out a razor-thin sliver of material to image. You'd use it to get atomic resolution images of say a singl

And the alternative technologies -- e.g. vapor deposition processes for thin film photovoltaics -- aren't exactly cheap either.

I wonder if it's feasible to mitigate the waste heat radiation problem by combining photovoltaics with thermoelectrics?

I think 31% is the thermodynamic limit for a single p-n junction, and 86.6 is for an infinite stack of them [0]. I'm not sure whether these limits apply to non-planar geometries. [0]: https://en.m.wikipedia.org/wiki&#x2

Why not just post the finalized version of the manuscript instead of the journal's typeset version? It's the same content, and most journals seem to be ok with this practice -- are preprint versions against APA's copyright po

You should try lighter gauge strings on your electric, and maybe lower the action (the distance between the strings and the frets). I generally find electric guitars much easier on my fingers than acoustics.

I think the idea is to use traffic calming methods to change the 'realistic' speed limit from 35 mph to 25 mph, and then post signs for 25 mph.

The issue with the simplifying "calories in == calories out" is that conservation of energy is being applied over the wrong system. Our bodies are not 100% efficient at extracting energy from food, and to GP's point respond d

Eh, I don't disagree with you that Congress is pretty one-sided right now, and unlikely to meaningfully oppose the executive branch, but I don't think your fatalistic attitude is all that productive. I don't think it's w

Congress, hopefully. Call your senators and representatives! There's a Senate bill that needs support. https://www.congress.gov/bill/115th-congress/senate-bill/248

Looks like it'll be a few months before we know if it's metastable at ambient pressure; they're planning to do the pressure release experiments at one of the national labs [0]. Here's the preprint [1] of the Science pape

They have a pretty plausible-sounding (I am not an aerogels expert) synthesis route based on cyclic annealing of graphene flakes, and they have molecular dynamics calculations to back it up. In the open access research paper [0] there&#x27

The original journal article is open access [0], and I think it's pretty well-written and accessible. This is a really great example of theory-driven materials design. [0]: http://advances.sciencemag.org/content/3&

It might be possible to come up with an analogy to adversarial images in object recognition networks -- just take a clip of the speaker saying the keyword ('Alexa', 'Ok google') and tweak it until it's no longer rec

I didn't mean to imply that the data wouldn't be useful, I was more asking to see if you had any specific questions in mind that this data could shed some light on. Relating download rates to citation is the first thing that comes

As a fellow scientist, I'm much more concerned with how others will interpret these access data. I'm not excited about the prospect of yet another unreliable signal for e.g. hiring committees to latch onto, as they often do with j
