Authorship can be weird. A physicist on a big LHC project will be the author on over 1000 papers after a decade or so (they average around 100 papers a year). In all likelihood they haven't read the vast majority of them, and have cont

I don't know if there's a "default" unit, but most people I interact with would use SI units (i.e. km, m, cm, mm, micron, nm, pm). Maybe more to your point, 630 nm is the same number of characters and a slightly more f

Yeah I guess I confused a lot of people: the charges are for the data, not the app. They are tiny, but if you use the app heavily and rely on it, you don't want to be disconnected when your data runs out.

That's the big point to me. Realistically next time I buy a new laptop it won't be heavily premeditated: the odds are that my old one will die and I'll need something that works that week. I don't want to end up buying a

I'd be interested to know too, the social graphs they can build must be mesmerizing to browse through.

Everyone I communicate with uses Signal now. In Europe using Signal costs the same amount as using WhatsApp, if not less because of the missing bloatware (backups etc). In a lot of the world, WhatsApp is free (I assume some kind of payment

I haven't heard of low-emissivity steel. Do you mean low-background steel [1]? My guess: low background steel is demanded more by low-background experiments like neutrino or dark matter detectors. Most of the LHC experiments work in an

I hadn't heard that about Alice. The CMS hadronic calorimeter was built from brass in old Russian artillery shell casings.

The LHC was brought down by a weasel: https://www.bbc.com/news/world-europe-36173247 It didn't survive. The article doesn't mention it but a physicist somehow got his hands on it, took it to a taxidermist to

I agree that using a colloquial definition is fine. And I don't mean to be too harsh on people who use buzzwords in their grant proposal: it's just sort of the sea you swim in. But I only wish we could say that a few hundred lines

In my field it's accepted (by some) that you write "AI" for your grant proposal and say "ML" when you talk to colleagues and want to be taken seriously. It feels a bit wrong to me, because as you say it's argua

In case people are wondering, you the IV injects a few hundred ml of saline, which most medical professionals would have access to. There were clubs that specialized in selling this to hungover people [1]. I wouldn't lightly risk sendi

I agree with your last point. I suspect MD is a popular option because it has job stability and good pay (which is likely related to the scarcity of MDs in the US). In my field (another type of research) a lot of people "want" t

The comparisons I've seen have generally been comparing ROOT on a problem it was optimized for to HDF5 (or whatever) out of the box on the same problem. There are a half dozen knobs to turn in any of these libraries, if you don't

It depends on how much data you have and what the rest of the stack looks like. If you have O(GB) of data that needs to be accessible in one python session you could just try out h5py: https://pypi.org/project/h5py&#x2F

It is a de facto standard: you can tell because the author of that post suggests rolling your own simpler data format as an alternative. There are indeed a lot of reasons not to use HDF5: if you have a lot of small records, are primarily
378.
by dguest 3y ago
In my experience HDF5 is like a simplified version of ROOT: doesn't provide a full data analysis suite, graphics library, or embedded compiler. It won't assume that everything in your data maps to a C++ type, or that every C++ typ

As someone else is eluding to, the concept of a virtual particle is kind of a calculation tool, but then so is all of quantum field theory. What you say sounds pretty alright to me: about as close as you can get without just following the m

I usually think of the Higgs mechanism (that gives mass) like the surface tension on a pond, whereas the Higgs boson would be ripples. It's not perfect (like any analogy).

It cost you (assuming an average taxpayer) less than 20 bucks and is the only way humanity will get at a specific kind of knowledge. But more importantly you aren't subsidizing it, you are paying for it outright. Subsidizing would su

This particular fact just sounds like good logistical sense. If I'm going to sign 2000 prints I might as well do it in one batch. Also might as well sign all them together, before mass production, rather than waiting for them to be dif

I'm sort of confused: you could have said the same thing about lead 70 years ago. I guess your point is that we had better prove with absolute certainty that this is a problem before we try to do something about it, since it would be a

Great, now drop the keyboard and it will be much more portable. Unfortunately you'd need a compact input device with good haptic feedback. Obviously it has a keyboard [1], but when the screen fits so nicely over it dropping the screen

I would assume that grocery store margins are that low because they price competitively, so this will just drop prices by a few % and the grocery store margins will stay the same.

The comparison between publications and handbags is cute... but yes, it falls apart for exactly the reason you mention. A prestigious journal would still be prestigious if they made publication free.
