  5. #paperOfTheDay is "On the Numerical calculation of a class of definite integrals and infinite series" by G. Stokes from 1850.
    This article is a follow up on the work of Airy I mentioned a few days ago, where the Airy function was introduced through its convergent integral representation. This function gives the intensity in interference patterns of light (e.g. the location of "higher order" rainbows). In #physics experiments, what one actually measures is the location of maxima or minima of intensity, which would correspond to the zeros of the Airy function. With the technology of 1850 it was hard to numerically compute integrals. Airy derived a convergent Taylor series expansion about zero, but from that, it is still hard to find higher order zeros.
    The present paper introduces a new approach to such calculations. The idea is to first derive a differential equation for the Airy function, and then use it to obtain a series expansion around infinity. This expansion is divergent (which is clear since the Airy function qualitatively changes character around zero), but it gives very high numerical accuracy for not-too-small arguments. In particular, one can obtain the locations of all zeros.
    The plot shows the true Airy function in black, and the first 9 terms of its convergent power series expansion around zero in red. We see that they reproduce the first zero, but completely miss all other zeros. The green curve is the first (!) term of the divergent expansion around -infinity. It is visually indistinguishable from the true function for all zeros. This high numerical accuracy of divergent series expansions is a typical feature seen in #resurgence computations.

  9. The #paperOfTheDay is "On the intensity of light in the neighbourhood of a caustic" by George Biddell Airy, 1838.
    This is a paper from the time long before anything quantum or relativity, where elementary questions of #optics were at the forefront of theoretical #physics . Since light has the character of both a wave and a ray, it is important not only where a ray can point, but also "how long" it is; one will find destructive or constructive interference depending on the difference of path length (in relation to the wave length). In the framework of geometric (=light ray) optics, this amounts to the fact that when light is reflected, a small change of the point of reflection does not change the total length of the path travelled to first order (i.e. light is reflected at such angle that the path length is stationary).
    For a point of focus, this relation is true not only infinitesimally, but for the full reflecting surface: All incoming rays sent to a focal point have the same length. Airy studies the intermediate case: Not ALL rays have the same length, but still, the difference vanishes to higher than first order locally. Geometrically, this gives rise to a "caustic", basically a focal point deformed to a focal line. The existence of such line amounts to the reflecting surface satisfying a certain differential equation. Most notably, for the total intensity (in the easiest case), Airy finds the expression
    integral from z=0 to z=infinity of cos(z^3 + t*z) dz , where t is a parameter. This function Ai(t) is nowadays known as the Airy function, and it constitutes the basic example of many effects in the theory of #resurgence and special functions in #mathematics .

  13. So, #StarTrek #Resurgence is gone from #Steam. It is still on Epic Games: store.epicgames.com/de/p/star-

    If you had any intention of buying it, this might be the last chance. I do not believe it will stay on Epic much longer. It's 23 bucks. Personally, I think that's a fair price. A single playthrough is roughly ten hours. This being a choose-your-own-adventure, you can at least play it twice in my opinion. If you're a TNG-VOY era trek fan, this game may be for you.

  23. I'm about four hours in to Star Trek: Resurgence, and I'm delighted. The game "feels" like Star Trek: competent and idealistic people doing their best, themes of trust and perseverance, moral dillemas, sweeping views of ships. I was surprised how "social" a game it is: very much you are navigating the expectations of your fellow crew members.

  26. À quelques pas derrière moi, l'eau sort de terre. Nous sommes au pied du village de Sauve, avec une belle résurgence où le Vidourle sort de terre après plusieurs kilomètres parcourus dans le karst. La terre, gorgée d'eau, y recrache un important volume des pluies assez intenses de ce début d'année.
    Un bon début de semaine à toutes et tous.

  27. YES, we must redefine the Party.
    But NO, we're not going back 40 years.
    The way is forward.

    And we shouldn't start by ASSUMING the Party must be centrist in order to win. Plenty of very liberal ideas are very popular with Americans. And many more would be if the right leader sold them with passion clarity.
