Modell257: Debajyoti Choudhuri wrote an introductional paper about the Fractional Laplacian that has applications to diffusion problems, probability theory, as well as image processing. Learn about harmonics that sound like music but are actually composed out of functions that solve the Laplace equation without a source term.

'Lewis takes up a debate with several Black feminists who have, at various times, questioned the idea of family abolition, whose central argument has been that, very often, Black families have been sites of resistance against racism. Similarly, we could point to many experiences of class struggle in which sectors of working families have played a key role against the attacks of capital: supporting strikes, establishing relations of solidarity between factories and neighborhoods, staging rent strikes, maintaining soup kitchens, creating movements in defense of public services, and many other forms of resistance. The tradition of “women’s commissions” in strikes, for example, has allowed the working class to articulate fighting forces far beyond the workplace.
'To this criticism Lewis responds that, even so, we should not cease working for the abolition of the family, since we would not need its “protective shield” if we managed to build a society without racism. The argument contains a grain of truth, but it stops halfway. It fails to contemplate the role that the family relations within sectors of the working class and oppressed can play in moments of heightened class struggle. On another level, it doesn’t account for the fact that capitalism, while it needs such a “social cell” for its own reproduction, constantly undermines working families’ very conditions of existence. Marx and Engels remarked on this in the mid-19th century, pointing to the length of the working day, the lack of decent housing, and the general precariousness of working class life.'

In der heutigen englischsprachigen Übung im Modul #ElectromagneticCompatibility haben wir die Fourierreihenentwicklung einer periodischen Rechteckpulsfolge untersucht, d.h. von Hand die #Fourier-Koeffizienten ermittelt, mit GNU Octave berechnet und grafisch dargestellt, mit LTspice simuliert und mit einem virtuellen PicoScope gemessen.

📌 The Fast #Fourier Transform (published by Cooley and Tukey in 1965) was another game-changer for us in the Signal Processing sector. Certainly up there with adaptive filtering (1960) in terms of lasting impact! This tech accelerated practical digital signal processors (#DSP).

In 1929, Kathleen Lonsdale solved the mystery of the molecular structure of #benzene, which had been elusive for over a century. She used #Fourier methods on her X-ray crystallography data.
Benzene had been isolated in 1825, in a tiny vial that would change the world. 👇

#Riemann is the room temperature #Superconductivity of #Mathematics. She is beautiful enough to make one cry as she tempts at a glance,then vanishes.The link between harmonic analysis , #Fourier , and pretty much all of #Physics takes a sledgehammer to the idea that mathematics and #Physics are twin sons of different mothers.This video is a not bad , very good introduction for newcomers. Timely and up to date

Oggi 15 novembre nel 1922 in quel di #Milano nasceva Giorgio Manganelli:
«Rileggere è una esperienza che non ha nulla a che fare con il leggere [...].
.
La prima lettura può essere anche un innamoramento;
ma esistono delizie di amorosità mentale che si abbandonano solo dopo anni di solidarietà, di complicità».
