You can describe it that way. But different parts of spacetime can have different curvature, so you get different impact of gravity. No matter how you describe it, gravity is different on Earth, Moon or in deep space and your theory has to

The problem with DLRs is that it makes cars more visible. And more vulnerable traffic participants such as bikes, pedestrians, skateboarders, etc. (that mostly don't have lights) less visible by comparison.

Why would we want to move away from them? Fortran is VERY good at what it is intended for (implementing formulas in code).

You can use the MPI C bindings just fine from C++?

Is there a nice screenshot that compares commonly confused glyphs like 1, I, l or O, 0, Ø?

I recently needed that backup road atlas. Not because GPS went down, but because I dropped my phone, killed the display and had to make it home 400 miles.

The LLVM implementation of libc++ is very young compared to other implementations (it was started 5 years ago or so), so there is still a lot of things missing and a lot of things that can be improved.

If there is any replacement in the HPC world (and I don't really see indications for that), it's Adios2.

If you work on supercomputers they feel a lot less sexy. As the old quote goes "supercomputers are devices to turn compute bound problems into IO bound problems". So you spend a lot of time fighting IO. (And thinking about memory

No, that is more national lab slang.

Quickly maybe. But to do it well you need a deep understanding of the material which is something that large language models lack.

What the line? "Science progresses one funeral at a time"?

That part is easy. But did being fat lead to health problems (that then also kill you), or did health problems lead to being fat (which then also kills you)? And that is before we get into the entire bit where the data shows that most of th

Sure. But is that a cause or an effect?

Things could certainly be better, but it is a but disingenuous to give the pure flight time of 1:15, when we all know that flying has quite a bit of time requirements on both ends. Not enough to bring it to 15.5 hours, but still easily enou

At least in my field the running joke is "it was published in Nature but it still might be right". Because Nature above all wants to be high impact. And you get that by publishing the controversial or unexpected findings. In other

I can list that in the feedback to the authors or recommend that in the confidential remarks to the editor. If they will listen (and force the authors if necessary) depends on the journal.

The problem is that "somewhat legible" is not a given and you don't know if the version that comes out of language editing (if it is still done, a lot of journals skip it to save money) is still scientifically correct. Edit:

There is definitely a difference between "public(ly available on arxiv)" and "published (in a peer-reviewed journal)". Depending what I want to do I may prefer on or the other for my work as a researcher.

You have no idea how atrocious the English is in papers that I see as a reviewer. And depending on journal I don't even get to reject it for that as long as the science is sound.

There is also the following suffixes for runway identification: S = STOL runway, G = glider runway, W = water sealane or waterway, and U = ultralight runway. For example runway 8G / 26G in KBDU (Boulder) and 3W / 21W in KSFF (Spok

I love OSMand for hiking and the ability to find routes and keep getting instructions even when you have no cell service is great for that use case. But I agree, for driving Waze is hard to beat. In particular the reaction to traffic data i

None of the impact of having your data leaked from your account is in any way modified by using a VPN for your data traffic while you are on the airplane. Hence the initial reply of that your suggestions of a VPN is irrelevant. Don't t
