Martensite formation is just one specific hardening mechanism in steels. Other hardening mechanisms (work/deformation hardening, pearlite formation, precipitation hardening) aren’t really amenable to additive processes - what’s the poi

NISTer here — We still have a password rotation policy, which I assume you are referring to in reference to [0]. I think they are working on it, but I’m not sure if we set our own password policy or if it’s something that needs to go throug

I think your position is reasonable. In the full perspective article [0], they advocate more for using this treatment to keep medical professionals from succumbing from the disease until a vaccine can be developed. And they propose what see

I do think it’s important to consider the pros and cons of any given policy, but I think this comparison is a bit extreme. There are about 35k car crash deaths in the US each year [0]. I’ve seen estimates for total infection rate all over t

Lots of nice content here. I started with the QM section, and it felt like you jumped right in to the particle theory of light. I realized later that of course you have an in depth discussion of the wave theory of light, but I think a bit m

I don’t think US carriers can legally institute a no-children rule — i think this sort of policy would constitute age discrimination [0]. Not sure about other localities. Removing particularly disruptive/belligerent passengers seems to

I really like the idea of unlinking publication from evaluation. Especially in CS people cite arxiv preprints all the time since the field moves so fast. I do this in my own work as well, but most of my field does not publish preprints on a

I think that would be great, but without getting several famous researchers to serve as editors for each new journal at the subfield level, it’s not going to address the real problem. Citations and impact (real and perceived) are the curren

The problem isn’t document hosting, it’s that the journals serve as a proxy for research quality, and everyone wants to publish in journals that have high (perceived and/or actual) impact. To effect real change the editors and promine

Do you have any pointers to great communities on pubpub? I’ve explored a bit and it seems like a really great idea, but I’m not sure how to find the most robust communities on there...

Personally I’d chalk the buzzwordiness up to upper management choosing the wrong people to talk with. There are plenty of great technical people working in the national lab system, but it’s not clear that whoever put together this list eve

Pandoc is great, but I’ve found that first running org-export to latex and then calling pandoc to the target format yields much better (and still not perfect) results. My main use case is exporting scientific manuscripts from org to semi-w

Definitely agree with assessment of high variance in programs and even individual groups. I think ‘yelp for academic groups’ is an interesting idea, but I really doubt the administration would step in unless it got really bad. But giving pr

The way they’ve formulated the problem, yes, I agree with you. There’s nothing really special about the deep learning model they used, and in fact they also tried gradient boosted decision trees.

The sorts of fatigue damage you get from cyclic loading aren’t necessarily a problem for the materials applications they’re targeting. Take the diamond transistor the my talk about — the idea is to apply an elastic strain that’d nominally c

No, and yes in a way. The quality of the venue matters a lot, and many people seem to obsess over h-index values, which quantify the citation count and journal impact factor. But in my opinion these things are useful but flawed heuristics f

Jupyter doesn’t track the execution history of your cells like this. However, you can run the shell commands straight from a notebook cell (use the %%bash cell magic or prepend the line with !). Not sure what to do about editing data files.

Most Ph.D. students receive a tuition waiver that's considered part of their compensation. Example, my Ph.D. was paid for primarily through an NSF grant that my advisor was awarded. An engineering Ph.D. student at my university costs t
