Dirk Lorenz @dirque.bsky.social · 08/06/2026I remember playing Civ 1 with somebody and we needed quite some time to figure out that Russian and Chinese looked exactly the same to him... 110
Dirk Lorenz @dirque.bsky.social · 02/06/2026That's a hell of a venue for a plenary talk here at #SIAMOP26 090
Dirk Lorenz @dirque.bsky.social · 16/03/2026Modern technology makes conference evenings in the hotel much more enjoyable! 150
Dirk Lorenz @dirque.bsky.social · 19/01/2026Universidad Técnica Federico Santa María in Valparaiso has a quite iconic campus tbh 150
Dirk Lorenz @dirque.bsky.social · 31/12/2025These tiles don't cease to amaze - with hexagonal holes you get a lot of symmetry! 030
Dirk Lorenz @dirque.bsky.social · 27/12/2025New periodic pattern from aperiodic tiles dropped: 🧮 #mathsky 0140
Dirk Lorenz @dirque.bsky.social · 19/06/2025I sample points uniformly on the sphere and then look at them on a map (in longitude and z-coordinate). STILL UNIFORMLY DISTRIBUTED! 🤯 (Quite a nice fact that is special to three dimensions: Each coordinate of a random vector uniformly on the uni sphere is uniform in [-1,1].) #🧮 050
Dirk Lorenz @dirque.bsky.social · 02/06/2025Look at what I produced! (\usepackage[cm]{sfmath} for more drama). 140
Dirk Lorenz @dirque.bsky.social · 27/04/2025Very nice! Reminds of this poem by the Austrian writer Ernst Jandl 020
Dirk Lorenz @dirque.bsky.social · 04/04/2025Well, there is this (taken from www.lesswrong.com/posts/Ng5n8F...), so is likely in the 75%-95% range… 010
Dirk Lorenz @dirque.bsky.social · 19/03/2025A mobile with cloth pins for some photos (and other light stuff). Sculptures of a thinker and of Ganesha (both presents of former group members). 000
Dirk Lorenz @dirque.bsky.social · 17/01/2025Another graduate student! Second to last one from TU Braunschweig - Emanuele Naldi graduated today with distinction! (Off topic remarkv Tbh, the best fitting suits I've seen in a thesis defense.) 040
Dirk Lorenz @dirque.bsky.social · 14/01/2025@tomkalei.bsky.social finishing his talk in our Colloquium on "The theories of oids" 😉 120
Dirk Lorenz @dirque.bsky.social · 13/01/2025Can be found quite frequently on menus in Italy. It's called Pizza Americana and some Italian twentysomethings told me that this was their favorite childhood option. 110
Dirk Lorenz @dirque.bsky.social · 10/01/2025Nice to be back to my old view! And it comes with some snow! 000
Dirk Lorenz @dirque.bsky.social · 06/01/2025It's a good idea indeed. It is so good that many kids in Germany between age 3 and 6 have this as one of their main modes of transportation. They still may need a few days to transition to a paddling bike though. 100
Dirk Lorenz @dirque.bsky.social · 04/01/2025How about this? Looks like a line integral (along a non-closed line) to me btw 010
Dirk Lorenz @dirque.bsky.social · 02/01/2025I am at the point in my life where the family calendar gets smaller 010
Dirk Lorenz @dirque.bsky.social · 16/12/2024Our awesome students made this announcement of the Christmas lecture I am about to give tomorrow here @unibremen.bsky.social ! 030
Dirk Lorenz @dirque.bsky.social · 13/12/2024I have an open postdoc (or phd) position! You know PINNs? You are interested in hands-on applications and love to work in a larger project? Then this position is for you! Please reach out if you have any questions! (Job ad only in German, unfortunately…) www.uni-bremen.de/en/universit... 080
Dirk Lorenz @dirque.bsky.social · 07/12/2024Post someone you've been told you look like who you definitely don't look like. 110
Dirk Lorenz @dirque.bsky.social · 06/12/2024People discussing who was first to use attention while clearly it was Fermat who introduced the concept of attention to scientific research with his marvellous margin note. 030
Dirk Lorenz @dirque.bsky.social · 18/11/2024Google scholar turned 20 and this is how it's celebrated 020
Dirk Lorenz @dirque.bsky.social · 20/09/2024Bluesky now has over 10 million users, and I was #794,815! Funny enough, that I joined on my birthday 020
Dirk Lorenz @dirque.bsky.social · 06/08/2024Well, I for one do not care for the Japanese chalk. Here in Germany we have awesome blackboards. No need for fancy chalk. Hagoromo does not write any better than the quite cheap Giotto Robercolor 000
Dirk Lorenz @dirque.bsky.social · 06/06/2024I seriously consider leaving the club if this fails again. As someone once said: I don't want to belong to any club that will accept me as a member. 010
Dirk Lorenz @dirque.bsky.social · 30/05/2024Sad news: Hans-Friedrich Münzner passed away recently on May 25, 2024 shortly after his 86th birthday. He is the guy who taught my analysis 27 years ago. His first words in Analysis 1 were "Numbers serve two things: Counting and ordering things" and somehow this got me hooked. 000
Dirk Lorenz @dirque.bsky.social · 03/03/2024Quite proud that I could work out the proof myself! 3/n, (n only 3) 010
Dirk Lorenz @dirque.bsky.social · 22/01/2024Still fascinated by the output of plt.plot(np.sin(np.arange(2000)),linestyle='',marker='.') 🧮 #mathsky 020
Dirk Lorenz @dirque.bsky.social · 06/01/2024Wolfram alpha lets you choose the normalization of the Fourier transform in a drop-down menu! Very neat! 000
Dirk Lorenz @dirque.bsky.social · 29/11/2023Seems like the app formerly known as Twitter is broken... 000
Dirk Lorenz @dirque.bsky.social · 27/11/2023I can't recall a time at which I found such an illustration in a math book helpful. (It's from Luenberger's "Optimization by vector space methods" which is awsome. But this illustration… 🙄 120
Dirk Lorenz @dirque.bsky.social · 27/11/2023Despite the delay I made it from Gare du Nord to Gare de Lyon on time and could by last leg. TGV to Lyon! 000
Dirk Lorenz @dirque.bsky.social · 27/11/2023German and French trains working together neatly: My delay on my way to Cologne is nicely captured by a delay of the train to Paris 😂 110
Dirk Lorenz @dirque.bsky.social · 27/11/2023Off to a half-day long train ride to the DIPOpt workshop on deep learning inverse problems and optimization in Lyon! 🤞 100
Dirk Lorenz @dirque.bsky.social · 24/11/2023Me, when I hear "A sequence gets closer and closer to its limit but can never reach it." 🧮 010
