Or is your handle @karsten?

@karsten-theis In mattersmodelling, this question could benefit from your insight in crystallography. Can you have a look on it? mattermodeling.stackexchange.com/questions/13909/…

In case you have a three-button mouse, a click with the left mouse boutton on the animated .gif opens a new tab of your web browser (e.g., Firefox) to display the illustration at original scale (i.e., considerably larger in dimension / easier to read). C'est tout.
Jan 18, 2023 21:13
However -- though these once mp4, no .gif equally may be optimized (e.g., use the same color palette for each individual frame, or reduction of the total of the colors used) -- the .gif typically is larger (in file size) than the .mp4.
Jan 18, 2023 21:11
Not only that you may determine the time each individual frame is displayed, the site offers you to crop/color optimize the gif to obtain a file of smaller file size. Instead of individual images recorded, the site equally allows to process videos, to extract the time intervals of interest, to change the dimension, and to convert it to an animated .gif, too.

To stitch them together into a .gif, I use the service by the Latvian ezgif.com.

During their creation, their file name already corresponds to the intended sequence (001.png, 002.png, 003.png, etc).

The above animated .gif consists of two .png individually recorded.

If you download such a photo from flickr, the one marked as the original still contains exif data the cropped ones do not:
May 22, 2024 16:12
I think photographers and divers interested enough into the technology equally might add these information to photos recorded to "tell a story" back at home.

Beside many tutorials how to extract such information from cameras of multiple suppliers. Ok, some of these cameras are not designed to operate under water and require a water tight hull, some however are able to operate under water, too. As it is possible to read out these data (a tutorial for example medium.com/@jrballesteros/…),
May 22, 2024 16:08
There even is a section of pictures on flickr reading flickr.com/photos/tags/geotagged, where this information is intentionally shared.
May 22, 2024 16:07
with the coordinates.

which is geotagged. I if open the exif data, and scroll down enough, I see this:

There is the camera icon, and a click on the exif data reveals plenty of details:

I just type seahorse in the basic search mask, and get multiple entries.

@Tom Does a platform to share images account as social media? I do think so. An example would I recognize would be flickr.com.

@AlexisKing Just because you write about FORTRAN era as about FORTRAN77 (anything since Fortran 90 and later [currently Fortran 2013, soon Fortran 2023] differs a lot from this): modern Fortran is well suitable in the math-inclined computations. See e.g. the discussion here here. And here, a modern beginner tutorial going well beyond the freely available 101 extracting some of of his book.

Later arvo, I will check-in here again.

Ok, the doi link reads: doi.org/10.1021/jp054903w
May 12, 2023 08:46
Perhaps @Martin (or an other subscriber with expertise in this field) can contribute here (because it is not my field).
May 12, 2023 08:43
By the landing page of the publication, ACS is aware of 35 publications citing this work.

So the imidic tautomer is experimentally known; «only» that these conditions are a bit outside the typical conditions in the typical preparative / synthetic ochem lab.

Very cool (referring to the temperature, below 20 K).
May 12, 2023 08:32
I just stumble over Matrix Isolation Fourier Transform Infrared Study of Photodecomposition of Formimidic Acid (J. Phys. Chem. A 2005, 109, 49, 11155–11162, doi.org/10.1021/jp054903w).
May 12, 2023 08:23
This would require some work to go through them, obviously.
May 12, 2023 08:23
Because the landing page of Becke's publication is aware of approx. 850 publications citing his work, perhaps there is a more recent (updated) perspective, too?
May 12, 2023 08:21
(I had the chance to read such one. About a decade later, the research cluster did not materialize at this scale, joint ventures with the big companies anticipated to be the breakthrough were at least delayed, large portions of the R&D moved to an other continent; you get the picture).

The (closing?) "The next fifty (forty-three) years will be as interesting as the first." reads (a bit too similar) to a grant proposal "and with these results, our planned start-up will create lead to a significant number of new jobs".
May 12, 2023 08:12
"the future looks bright" on one side, vs "we cannot, quite yet forget the basics" and "DFAs, local or nonlocal, will never be exact".
May 12, 2023 08:11
A comment to the additional reference to the Becke paper published by 2014. As someone not engaged in the field of quantum chemical computations -- thankfully, there are folks trained in this field -- the quotes appear for me slightly contradicting each other.

@AustinHemmelgarn Nitpick: FORTRAN77, yes, but much less likely the subsequent ISO standards Fortran2003 (e.g., OOP), 2008 (e.g., coarrays), and 2018. Standard 2023 is just around the corner, too. Be welcome to visit e.g., fortran-lang.org/en, package index, or fpm package manager. Where suitable, modern Fortran (different spelling) is well alive (e.g., github.com/Beliavsky/Fortran-code-on-GitHub).
