Actually, at least in the US, physics is funded because of things like the atomic bomb and the transistor, as GP points out. Observe the rhetoric of any congress member. They don't care if physics is "cool", any more than the

What I would like is to be able to explore the full citation graph, both interactively and programmatically. I think it would make identifying the key literature in a new topic much faster.

There are some interesting points here, but I don't think the author adequately addresses research funding transparency concerns. Many funding sources require researchers to include a grant number in any publication. This would effecti

You can't boil lead out of water, in the same way that you can't boil salt out of water. Metal extraction is a pretty hard problem. It seems that you can reduce the levels of the aforementioned trihalomethane compounds by boiling

The blog post explains why the behavior in question is cheating, not a "useful shortcut". Overfitting a model isn't a real advancement to the field. The point is to take a closer look at the current benchmarks and potentially

I don't know. The debt level is relative to the national average, and it ranges from -100% (zero loans) to over 700%. It's not like they fabricated many 'high' levels, the distribution just has a long tail. I think a div

I almost think that's a good thing. It would be a talking point for gathering support for widespread open access policy.

It depends on the publisher copyright agreement. With many closed journals, the researcher is free to post a preprint on a personal site or to something like arXiv, but not to post the final version with the journal's "value-added

You could, but typically the editor of the journal asking for reviews is a leading academic in the field of the journal. Refusing to review non-open work sounds like a good way to burn political capital for those early in their careers.

The FASTR act in the Senate would essentially implement the funding side of this. Changing tenure policies is also an important component in getting a culture shift towards open research. http://www.sparc.arl.org/advocacy&#x

Probably it's lack of infrastructure buy-in. And personally, I find the misuse of the word biometric in the white paper off-putting, along with the lack of detail on the basis for the technique. The fingerprint is somehow related to t

On the other hand, more pedestrian traffic also may enable additional business, as people are more likely to wander in and out of shops, and they aren't competing for limited parking availability.

I agree that coping skills are an advantage, but you seem to be suggesting that a decline in emotional expression has led to or somehow enabled industrialization. Causality probably runs the other way around. The author suggests a plausible

It sounds from the blog post like this skimming device is reading the electrical signal from the card reader, not reading the mag-stipe directly. So it's unclear how much this would help. I would think chip and pin should mitigate this

Your numbers for PhD stipends are a bit high. I wouldn't be surprised if SCS students were paid that much, but the typical stipend for the rest of us is more like 24k/year. Even so, there's a PhD student in my program who bou

Even at schools with actual athletics programs and budgets, most PhD students are paid with grant money won by their advisors, or through government fellowships. Not by the university. (I'm a PhD student at CMU paid with NSF grant mone

The problem is specifically the ultraviolet photons in the sunlight, which photoactivate the reaction between bromine ions and ozone to form bromate [1]. The visible color shouldn't matter as much as strong absorbance or reflectance in

For most Elsevier journals, you can post your preprint or even the accepted manuscript online--for example on a personal site or the arXiv. Sometimes I wonder why this point isn't brought up more often in discussions on open access pub

CMU's tuition is indeed quite high, but it's actually 50k$ per year for undergraduates. The 65k$ you quote includes campus housing and dining services, so it's not really fair to compare that figure to tuition costs elsewhere

I'm not aware of any major breakthroughs in the past few years, but lead-free solder alloys are an active research area right now. Here's a SANDIA report from 2012 that has some context and some cool micrographs; you can find lots

I think it'd be pretty difficult to do for arbitrary liquids, because i imagine there would be some non-trivial temperature gradients. You'd probably have to account for the heat capacity and thermal conductivity of your soup to g

In the original article they say they cold-roll, recrystallize, then strain harden. So definitely no casting, because the recrystallization is where the magic happens. Rolling and casting should be fine though. They say that the alloy is mo

That's a really interesting question, and I'm not sure what the answer should be. According to the authors, the B2 intermetallic forms in small particles during recrystallization at 900 C because of the influence of the nickel, so

That's a really good point. Interestingly, the Nature Letter (paywall) [0] doesn't seem to mention the aerospace industry at all. It's more targeted toward structural and automotive applications. I'm not sure where The E
