This is a really interesting point. I've definitely passed on reading papers that seemed potentially relevant because my institution didn't have a subscription to the journal.

I don't see this as a workable solution. You can't neglect to cite relevant research ideas simply because they were published in a closed journal, and there often isn't an open alternative to cite. I think you really need to

I use a dvorak layout, and I find it much more comfortable than qwerty. When I need to use someone else's machine for something nontrivial, I just change the OS setting temporarily. The overhead doesn't bother me, and the only thi

What kind of issues have you run into with Python 3 that make data science more difficult? I use Python 3 as well, and I don't think I've run into anything that fits your description...

what you're describing is essentially what people try to do with molecular dynamics and kinetic Monte Carlo methods, which are even older methods than density functional theory. There's currently a lot of interest in the materials

Perhaps late to the thread, but turbine blades with internal cooling channels are one of the dream applications for metal additive manufacturing, though I'm not sure it may ever be realizable. If you could lower the operating temperatu

It's actually much less safe in most places. The speed differential between bikes and pedestrians is too high, and drivers can't see cyclists as easily when making turns or pulling into/out of driveways. Writing as a cyclist

Not really relevant -- most of the computer systems used to actually carry out research are paid for with grant money of some flavor. The university computing systems are more incidental

You have to start somewhere. In addition to bootstrapping the program in a few cities, they are probably using this data to improve their pothole detection systems. Pittsburgh's a great city for that sort of thing.

All these challenges are exactly why one would want to collect driving data in Pittsburgh, it seems to me. I saw a heavily instrumented Uber car driving down Liberty two days ago.

I'll second the Harry Potter books -- I've been reading the Sorcerer's Stone (electronically) in Portuguese after working through Duolingo. It's nice because I am familiar with the story and there's loads of new voc

It's a fairly common informal way of writing the chemical formula (H2O2) that tries to be a little more faithful to the geometry of the molecule... so HOOOH is hydrogen perperoxide, literally a chain of three oxygen atoms with a hydrog

I think [0] or [1] might be a good place to start, depending on what you want to do with it. Both take a similar to this blog post, in that they also use the VGG networks trained on ImageNet. Specifically, [0] uses Fisher Vector pooling on

I have never heard of peer reviewers being paid in my discipline (materials science). Even the editor is usually a volunteer, though sometimes they are paid a small honorarium...

I found this summary a bit hard to follow, so I read the 2008 Nature paper the author refers to [0]. (It's behind a paywall, but the supplemental materials in [1] are available.) It seems like Silicium is using an approach that's

What about liability insurance? A main driver for development of autonomous cars is to reduce the rate of traffic fatalities. Once this is realized, shouldn't insurance rates for human drivers increase to reflect the change in relative

Berkeley isn't exactly a typical state school though. It'd be interesting to see a more comprehensive dataset.

That report makes some interesting points about the increasing role of student loan debt covering the rise in tuition. They don't really suggest what universities should do though, it's more state-level reform: standardize admissi

I feel like the odd one out considering an academic career in my engineering PhD program. I don't think the attitude you're describing is all that common in many technical fields these days. I'm sure it depends on the field,

I don't think that's a fair reading. I think it's reasonable to suggest that state governments ease up on the beauracracy in light of the decline in funding.

It was not expanded. i think you're referring to the FASTR bill that has not yet (but hopefully will soon be) passed. https://en.m.wikipedia.org/wiki/Fair_Access_to_Science_and_T...

NSF funding isn't really a fair comparison, because Pitt is most well known for its excellent medical research. $4.5 million in NIH funding at CMU vs $79.9 million at Pitt in FY2016... Plus CMU and Pitt collaborate quite a lot, especia

Another potential solution is for the mobile carriers to charge the ad networks for the bandwidth they use. That's more aligned with the incentives the mobile carriers have, more fair to users, but it might be detrimental to the earnin

I don't think it's silly at all. I think you have a good point about this particular contest, but there are plenty of other applications where training data is prohibitively expensive or time-consuming to collect. One way to proce

The FCC and HCP lattices are 3D concepts, but you're on the right track. They're using a square lattice, but you could get a higher density using a hexagonal one. What's really interesting is that they're modulating drop

The temperature would be a nice addition -- it may be a sunny morning where I am, but it's also 21 degrees (-6 C).

I think a lot of the confusion in this discussion is coming from the specific example. The fine structure constant, an aspect ratio, or something like Reynold's number for quantifying fluid flow turbulence -- these are all dimensionles

I think I agree with you about the quality of the science journalism here[1], but I thought the actual text wasn't as sensational as you're making it out to be, despite the title. I didn't read it as a call for completely rev

The review article here suggests that language processing steps are the bottleneck, not we movement. So the reasearch suggests that current approach to using tech (rapid serial display of words) introduces a speed-comprehension trade off. P

The reason for this is that the battery tech simply isn't really there yet. Battery tech is an intensive research area still, even at the basic sciences level. Does it make sense for companies to standardize if they're still itera
