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.
Our bibliometric analysis combines data from #Dimensions, @OpenAlex and @crossref.
Availability of reliable data on links between peer-reviewed outputs and preprints is limited. Our statistics provide a conservative estimate of preprint adoption. The actual adoption is somewhat higher.

We urge stakeholders in the research system to work with innovation-friendly bibliographic databases. Examples of databases that are more supportive of innovation include #Dimensions, @OpenAlex and #EuropePMC, among others.

A #Question for #Krononauts
A #shoebox is floating in #SpaceTime. We can #identify its 2 sides as X, its ends as Y, and top & bottom as Z. Now, rotating the box, the Xs might become Zs, or some other 2- or 3-way inversion.
4-D might have X, Y, Z & T (for Time). Could these 4 #axes or #dimensions also be "rotated"? Could someone live in "#spatial" dimensions of X, Y & T, with Z being their Time? If so, could our X-dimension be someone else's Time #dimension?
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.
Whilst I can understand why a #microwave is #beeping (makes it accessible to #blind people when there are no physical buttons that are tactile), I have a way bigger issue with them:
Outside dimensions? shure.
Inside volume? Yes!
But something as simple as #dimensions on the inside...
#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. ❜❜

The concept of higher dimensions beyond the familiar three of space and one of time poses intriguing questions. If these dimensions exist, how are they structured? Theoretical frameworks like string theory suggest the presence of extra spatial dimensions, potentially compactified in complex internal spaces too small for direct observation. Exploring this could unlock a deeper understanding of fundamental forces and reconcile quantum mechanics with gravity. #Physics #Dimensions #StringTheory

#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"…

One of the hopes of #TimeTravel is #communication — with (#extraterrestrial, #NHI) #beings beyond our immediate #spacetime. Think of #SETI, #CarlSagan, and the #Voyager program.
Constructs like #amplituhedra are functioning "beneath" spacetime. Could this suggest new modes or #dimensions of communication? Instead of reaching way "out" across distances, like the #spacecraft, could there be ways of reaching way "in"? Encoding dots & dashes into the collisions of quantum particles?
#Scientists Discover a #Jewel at the Heart of #Quantum #Physics.
…"The #Amplituhedron looks like an intricate, multifaceted jewel in higher #dimensions. Encoded in its #volume are the most basic features of reality that can be calculated, “scattering amplitudes,” which represent the likelihood that a certain set of #particles will turn into certain other particles upon #colliding…

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.
