A new preprint examines 87M publications and 1.5B citations (1990–2023) via @OpenAlex & #Dimensions. While English still dominates (>85% in 2023), publication shares in Indonesian, Portuguese, and Spanish are growing - thanks to regional infrastructures like SciELO and OJS.

English acts as both a bridge and a barrier: it facilitates global exchange but marginalizes non-English research.

There are indeed major differences between fields in the physical sciences, with Astronomical and Space Sciences as well as Quantum Physics having the highest preprint adoption, followed by Atomic, Molecular, Nuclear, Particle and Plasma Physics. See the figure below for more details.

Note: Field definitions are based on the Fields of Research (FoR) classification in #Dimensions.

Continued thread

I used the #Dimensions paid web interface on Jan 6, 2025 to try and replicate the numbers. Dimensions has a ready-made filter (which I helped create) to add ~250 US federal funding agencies to a search with one click, so limiting the results is easy.

Results vary depending on single year / lumping all years together and which document types are included.

#Robot has Six Degrees of Freedom

❛❛ #dimensions & #degrees of freedom are not the same thing. While they may have a similar analogy as shapes and dimensions, they are distinct #concepts. In a #3D #mechanics context, #objects can have 6 degrees of freedom, which is not the same as the 3 dimensions of #space. ❜❜

#Dimensions of #Curiosity
Lucía Martín-Merchán disproves long-standing pure mathematics conjecture

…"While research into higher dimensions may seem obscure … 'If we only do research based on what we already know is useful, we will limit our discoveries,' she says. 'You never know what in the #future you will need.'

Still, she acknowledges, a large part of what motivates her inquiry is pure curiosity"…

A Beginner's Guide to the #FourthDimension

Combining simple images with multi-dimensional #animation, this 6-min video illustrates basic concepts of objects in a #4thdimension. If you find this interesting, you can search on other animated videos of 4 #dimensions and higher — some being many times more complex than this one.
