The spacing on the demo's "Outline" slide is like nails on a chalkboard, but I really like seeing folks center accessibility in LaTeX tools (this one uses LuaLaTeX). Historically they have not been good at this. 🧪

Call for Editors at the Open Journal of Astrophysics The number of papers submitted to the Open Journal of Astrophysics continues to rise, as demonstrated by this nice graphic which shows the stats for new submissions for the last five years: It's very clear that the thicket is getting thicker! The increasing number of articles is of course very welcome indeed, but it is increasing the load on our Editorial Board and that includes me!

Hilariously bad idea. In my subfield author lists are almost always alphabetical!

A royal gold medal _The Royal Swedish Academy of Sciences_ (IVA, the same org that selects winners for three of the Nobel prize categories) awards me a gold medal 2025 for my work on curl. This academy, established 1919 by the Swedish king Gustav V, has been awarding _great achievers_ for over one hundred years and the simple idea behind the awards is, as quoted from their website: > Gold medals are awarded every year to people who, through outstanding deeds, have contributed to creating a better society. I am of course humbled and greatly honored to have been selected as a receiver of said award this year. To be recognized as someone who **have contributed to creating a better society** , selected by top people in competition with persons of remarkable track records and achievements. Not too shabby for a wannabe-engineer like myself who did not even attend university. There have been several software and tech related awardees for this prize before, but from what I can tell I am the first Open Source person to receive this recognition by the academy. ## Justification The Academy’s justification is given in Swedish (see below) but it should be translated roughly like this: _System developer Daniel Stenberg is awarded the IVA Gold Medal for his contributions to software development, where he has been central to internet infrastructure and free software. Through his work with curl, the tool that is now used by billions of devices worldwide, he has enabled reliable and secure data transfer over the internet. Not just between programs in traditional computers, but everything from smartphones and cars, to satellites and spacecraft._ The original Swedish “motivering”: _Systemutvecklare Daniel Stenberg tilldelas IVAs Guldmedalj för sina insatser inom mjukvaruutveckling där han haft en central betydelse för internetinfrastruktur och fri programvara. Genom sitt arbete med curl, verktyget som i dag används av miljarder enheter världen över, har han möjliggjort tillförlitlig och säker dataöverföring över internet. Inte bara mellan program i traditionella datorer utan allt från smartphones och bilar, till satelliter och rymdfarkoster._ ## The ceremony The associated award ceremony when the physical medal is handed over happens this Friday at the Stockholm City Hall‘s Blue Hall, the same venue used for the annual Nobel Prize banquet. I have invited my wife and my two adult kids to participate in those festivities. ## A _second_ medal indeed Did I not already receive a gold medal? Why yes, I did eight years ago. Believe me, it does not _get old_. This is something I can get used to. But yes: it is beyond crazy to get one medal in your life. Getting _two_ is simply incomprehensible. This is also my _third_ award received within this calendar year so I completely understand if you already feel bored by my blog posts constantly banging my own drum. See European Open Source Achievement Award and Developer of the year for the two previous ones. ## The medal I wanted to include a fine high resolution image of the medal in this post, but I failed to fine one. I suppose I will just have to make a few shots by myself after Friday and do a follow-up post!

A black and white photo of Albert Einstein, around age 25, sitting at a desk. He is a wearing a flannel suit and resting his right arm on the desk. Einstein is looking to the left of the photographer in this posed photo.

The first paragraph of the paper, in German. Translated to English is reads: It is known that Maxwell's electrodynamics—as usually understood at the present time—when applied to moving bodies, leads to asymmetries which do not appear to be inherent in the phenomena. Take, for example, the reciprocal electrodynamic action of a magnet and a conductor. The observable phenomenon here depends only on the relative motion of the conductor and the magnet, whereas the customary view draws a sharp distinction between the two cases in which either the one or the other of these bodies is in motion. For if the magnet is in motion and the conductor at rest, there arises in the neighbourhood of the magnet an electric field with a certain definite energy, producing a current at the places where parts of the conductor are situated. But if the magnet is stationary and the conductor in motion, no electric field arises in the neighbourhood of the magnet...

Happy 120th birthday, special relativity!

Albert Einstein introduced special relativity in the paper "On The Electrodynamics Of Moving Bodies," published in Annalen der Physik #OTD in 1905. 🧪 ⚛️ 🔭

This is exactly right, and students are often surprised to hear it. It’s one of the first things I explain in the “Should I use LLMs?” portion of my syllabus.

The power law found is no different from the 1/r^a scaling present in the age-old and ubiquitous gravity law of mobility... It's literally the exact same thing. 🤷

But it's interesting that it seems to go all the way down to tens of meters.
