The goal of academic research is to create understanding, not papers. If we outsource all research to LLMs, then we are only producing the latter.

The NRPy package and tutorials are a good place to start: https://nrpyplus.net/

You should check out Sage Manifolds [1]. It's built on top of Sage Math, but I think it can also use SymPy as computational engine. [1] https://sagemanifolds.obspm.fr/

The finite-differencing time-domain method [1] (sometimes also called leap-frog [2]) is easy to implement and robust for scalar and electromagnetic waves. This other book by LeVequ…

Matter in neutron stars is compressed together by the enormous gravity. Once set free on your floor, this material would no longer be held together and will start expanding at clos…

I think this is, at least in part, specific to the US/Western tradition. US physics curriculum is built to get people up to speed with quantum physics ASAP, because this is the cor…

RAS used to have all articles available to everyone for free after 1 year (immediately if one wanted to pay for open access). I thought this was a reasonable compromise. The new po…

This is interesting, but all of the links I tried were broken or led to broken pages. Unfortunately, with the widespread use of LMSs a lot of useful material is now behind Universi…

DOE [1], NASA [2], NSF [3] already require most research papers to be made publicly available. --- [1] https://www.osti.gov/ [2] https://www.ncbi.nlm.nih.gov/pmc/funder/nasa/ [3] h…

Most of the federal grants I am aware of have duration of 3+ year (the typical duration of a PhD after having completed the course work).

Perhaps Jamendo https://www.jamendo.com/ ?

Coincidentally, Alcubierre recently posted a review article on warp drives: https://arxiv.org/pdf/2103.05610.pdf . It looks like a good introduction to this topic.

I would also recommend "The Large Scale Structure of Space-Time" by Hawking and Ellis. It uses some advanced mathematics and some prior knowledge of GR, at least at the level of Sc…

For what it means, I know some of the people on that list and I can say that they are real scientists.

It is in the first page, but the link points to the FAQ instead.

C has the "restrict" keyword to indicate that no aliasing should occur.

Single academics will likely not bother with Office365/Google, but University administrators are the ones buying enterprise software. In the past few years the trend has been for t…

Exactly. The data is about the backgrounds of data scientists, but is incorrectly interpreted as the probability of becoming a data scientist given a certain background. Obviously …

I am just thinking that, if future archeologists discover these warnings / language in frequent association with art, then they will probably not think twice about excavating an ac…

Doesn't embedding these messages into art defy their very purpose of being a warning?

Fully agree. Academic career is already demanding enough without having to force each scientist to run his/her own PR operation. Outreach is important, but it is better done at the…

I got my PhD in 2013 (computational astrophysics / general relativity), I did almost 6 years as postdoc at two different institutions, and I am about to start a tenure track job. I…

I work on gravitational wave related science. I am not part of LIGO, so I speak only for myself. I think that most people in the scientific community have no doubts on the interpre…

I have studied in Europe (Italy and Germany) and now I am in the academia in the USA. Having student evaluate professors has been the standard practice for many years in Europe. I …

They are usually sold refrigerated in Italy
