Born #onthisday in 1736, Joseph-Louis Lagrange was an Italian Enlightenment Era mathematician and astronomer (later naturalized French). He made many significant contributions to the fields of analysis, number theory, and both classical and celestial mechanics.
Lagrange was one of the creators of the calculus of variations, deriving the Euler–Lagrange equations for extrema of functionals. He also extended the method to take into account possible constraints, arriving at the method of Lagrange multipliers. Lagrange invented the method of solving differential equations known as variation of parameters, applied differential calculus to the theory of probabilities and attained notable work on the solution of equations. He proved that every natural number is a sum of four squares. His treatise "Theorie des fonctions analytiques" laid some of the foundations of group theory, anticipating Galois. In calculus, Lagrange developed a novel approach to interpolation and Taylor series. He studied the three-body problem for the Earth, Sun and Moon (1764) and the movement of Jupiter’s satellites (1766), and in 1772 found the special-case solutions to this problem that yield what are now known as Lagrangian points.
Lagrange also transformed Newtonian mechanics into the branch of analysis that we now call Lagrangian mechanics and presented the so-called mechanical "principles" as simple results of the variational calculus.
I wrote a bit about Lagrange mechanics and the Euler-Lagrange equation here: https://davidmeyer.github.io/qc/pola.pdf. As always, questions/comments/corrections/* greatly appreciated.

So, how do you get #Lagrange to change the icon it associates with your #Gemini capsule? I thought it was favicon.txt, but I've already added an emoji to /favicon.txt and it hasn't switched over. :thonking:
He fediverse, I have a fairly specific reality check question about spatial data, are any of you folks good at that? Specifically what happens when you assign values to individuals such as census or NASA data and then run model that don't include a spatial matrix.
As I understand it spatial autocorrelation can drive your associations away from the null and other threats to validity so not testing it is a Bad Thing.
I've looked at this in the past but it was in the context of spatial clustering using GeoDA where I'd get an OLS analyst and also Lagrange statistics to look at local and regional clustering. But that was population level data and this context is a cohort study.
Almost done with new features for #Lagrange v1.17. As one of the last touches, I'm adding Gemtext syntax highlighting in the upload dialog. Together with a couple of other tweaks, this makes it much nicer to write gemlog posts in the app.
(Now I only need to find some time for gemlogging...)
India successfully launched its first-ever solar observatory Aditya-L1 earlier today.
Aditya = Sun in Sanskrit
L1 = Sun-Earth L1 Lagrange Point
After a few orbit-raising maneuvers and a maneuver to leave Earth's Sphere of Influence, Aditya-L1 will be inserted into the orbit around L1 ~109 days from now.
Aditya-L1 will be stationed in a Halo orbit around the L1 point, from where it will get an unobstructed view of the Sun.
It's a lovely companion to the epub-formatted book, which zathura occasionally has issues with (usually preformatted code snippets running off the right side of the page), but the gempub version opens beautifully in #lagrange
I've decided to bump #Lagrange to v1.16 since there is a couple of small new features now implemented, like this input prompt zooming that helps you better see what you've written when typing a longer message.
It uses the same Zoom In/Out/Reset keys as the browser page.
