  1. 13 000 millionnaires ne paient pas d'impôt sur le revenu : Amélie de Montchalin a menti et doit démissionner de la Cour des comptes
    france.attac.org/actus-et-medi
    Le 14 janvier dernier, Amélie de Montchalin, encore ministre des comptes publics, affirmait pourtant devant l'Assemblée nationale « Il n'est pas vrai que des dizaines de Français fortunés ne paieraient aucun impôt sur le revenu, il n'y a pas de document à Bercy qui le montrerait ». Elle a donc menti devant la représentation nationale et ne peut pas rester à la tête de la Cour des comptes.

  2. Conditional Aggregation with CASE?!

    CASE inside SUM creates conditional aggregation! You can sum only certain rows based on conditions. This conditional math will transform your data!

  7. Attac dénonce un budget injuste alors que des milliers d'ultra-riches paient zéro euro d'impôt sur le revenu
    france.attac.org/actus-et-medi
    Après les propos de l'ancien ministre de l'économie reconnaissant que les plus riches échappent à l'impôt sur le revenu, Attac demande à faire payer leur juste part d'impôt aux riches plutôt que de voter un budget qui sacrifie les services publics et la protection sociale.

  10. Dear Whinging Friends, ​:ablobcatbongokeyboard:​
    As we in the UK (allegedly) know, 'musn't grumble'. Maybe we should a little more?
    - Brexit? Bet you can't eat three? Eh wait that is wheatabix, readybrex, shredded wheat/wit? Something tasteless with added sugar rush?
    ​:ablobcatpopcorn:​
    - The
    #weather is now so #unpredictable we can talk about it and whinge even more. Result!
    - We are now
    #bank ruptured. Oh the #humanity

    Easy to be a whinge bag.
    #Fortunately we have some of the #brightest minds in the IMPerial Empire of little In-gland:
    - Pubic [sic] transport run by runner haz beans...
    - Schools making way for Pink Floyd, 'We don't need no education, Teacher leave them kids alone'.
    #Sum mishtake surely.

    #Food #grown in #inns and out of hunger #allotments 🥬

    Expect more surprises. As they happen, mostly by accident...

  16. Try to prove the following two results that relate the harmonic numbers to the golden ratio. Have an excellent weekend.

    \[\displaystyle\sum_{n=1}^\infty\binom{2n}n\dfrac{H_n}{5^n}=2\sqrt5\ln\varphi\]

    \[\displaystyle\sum_{n=1}^\infty\binom{2n}n\dfrac{H_n}{5^nn}=\frac{2\pi^2}{15}-2\ln^2\varphi\]

    where \(\varphi=\frac{1+\sqrt5}2\) is the golden ratio; and \(H_n=\left(1+\frac12+\frac13+\ldots+\frac1n\right)\) is the \(n\)-th harmonic number.

  22. Jeszcze tylko 2 tygodnie do jednego z największych wydarzeń popularnonaukowych nie tylko na Śląsku, ale również w kraju i w Europie! :ablobcatattention: Jak możemy przeczytać na stronie wydarzenia, sześć dotychczasowych edycji zobaczyło 555 tysięcy osób.

    Śląski Festiwal Nauki - bo to o nim mowa - to wydarzenie, które od 2016 odbywa się co roku. Organizowane jest przez uczelnie z województwa śląskiego, które od 2018 roku na mocy porozumienia tworzą konsorcjum. Liderem porozumienia oraz inicjatorem i głównym organizatorem wydarzenia jest Uniwersytet Śląski w Katowicach a współtworzą: Miasto Katowice, Górnośląsko-Zagłębiowska Metropolia, Urząd Marszałkowski Województwa Śląskiego, Politechnika Śląska, Śląski Uniwersytet Medyczny, Uniwersytet Humanistyczno-Przyrodniczy im. Jana Długosza, Politechnika Częstochowska, Uniwersytet Ekonomiczny w Katowicach, Akademia Wychowania Fizycznego im. Jerzego Kukuczki, Akademia Techniczno-Humanistyczna w Bielsku-Białej oraz Akademia Sztuk Pięknych w Katowicach.

    Program tegorocznej edycji budowany jest w oparciu o sześć ścieżek tematycznych Europejskiego Miasta Nauki Katowice 2024: klimat i środowisko, zdrowie i jakość życia, przemysły przyszłości, innowacje społeczne, dziedzictwo przemysłowe i kulturowe, kreacja i krytyka. Ponadto realizowana będzie tematyka związana z siedemnastoma celami zrównoważonego rozwoju ONZ.
    Co więcej, po raz pierwszy zostało zaplanowanych nie dwa dni atrakcji, a trzy! 😃

    Siódma edycja ŚFN odbywa się od 9 do 11 grudnia w Spodku i Międzynarodowym Centrum Kongresowym w Katowicach.
    Godziny otwarcia:
    • sobota i niedziela (9.12, 10.12): g. 10-18
    • poniedziałek (11.12): g. 8-16
