Got a flu shot for the first time since I can remember. Sadly my company didn't offer a Covid shot on top. In Austria there is also the free of charge shingles vaccination, plan to get that one too ๐Ÿ’‰๐Ÿ˜Š

Habe heute einem gut 70jรคhrigen ehemaligen Spitzenpolitiker zugehรถrt, der fordert: Die Leute mรผssen frรผher aufstehen und mehr arbeiten. Und im Alter lรคnger im Job bleiben. Strengt euch an fรผr mehr Wirtschaftswachstum!
Und ich kann diesen Zynismus nicht mehr hรถren. (Thread)

As a physicist, I can sleep well. There are still lots of interesting simulations to be run and specific understandings to be gained. And we still love you Euler equation! โ™ฅ๏ธ

I finally had some time, so I installed #BazziteOS on my gaming laptop, and so far, so good! As well as being able to play games, I can also compile code, and the power management is much better under Linux. Windows kept the fan speed rather high, which my wife joked about constantly. Next step D3 ๐Ÿ‘น

These Pied Piper Banach and Tarski and when you try that with money it simply doesn't work! Don't listen to these Sirens, the truth is out there!

By the way, I firmly believe that letters are the highest form of academic publishing. I'm not suggesting that we should aim for that in this case, but starting with around 20 figures might be a bit excessive.

So over the last half a year, a colleague generated results for a paper that we are writing. The colleague is a rather fresh PhD student and he did some amazing simulations. But as I learned myself having nice results is only 1/3 of a done paper. Currently sorting what will end up in the appendix ๐Ÿค”

This would be an insult to "pseudocode", which is usually a helpful tool. Why even change it now?

That is true, even for most of the smaller roads up some unknown mountains. Still cycling infrastructure in larger cities left a lot to be desired.

Loved cycling in Denmark so much because of this! Now back in Austria I feel like I got too close to the sun.

I remember Prof. Uwe Thiele from Uni Mรผnster has worked on that topic. I think one of his PhD students was able to build a model for the fingering instability.

This sounds like a lot for a single semester! In physics, we had three or four calculus classes for the first three or four semesters ๐Ÿ˜…, and I vividly remember struggling with all of them ๐Ÿ™ˆ!

Meet the "Japanese snow fairy" (shima enaga), a subspecies of long-tailed tit native to Hokkaido.

It's no wonder Japanese anime characters look like they do, when actual Japanese wildlife looks like this:

This both crazy cool and scary. Getting physics models from just a few prompts is awesome. The fail safe shown with the energy balance is a neat feature! However, I'm not sold on this whole democratication of simulations approach. If you can't verify your results, things become dangerous.

Also big shout out the organizers, the event was well executed and about 14000 were running that day ๐Ÿ˜Š๐Ÿƒ๐Ÿ‘

What a race! Weather was perfect, almost too sunny ๐ŸŒž.I started very much in the front of the block and it was rather nice to start with so many fast runners. My pace was too hot and I paid for it. Kilometers 17-18 were 20sec behind target. Still smashed HM PB by more than 3min ๐Ÿ˜„

Stupid question, but isn't this too hot for bacteria to survive? I thought micro organisms, like bacteria, are the source of the composting process. Can worms survive that heat?

This Sunday is the #GrazMarathon and I'm looking forward running 21,1 km. I'm a little bit afraid of the weather, although there is currently no rain predicted. Hoping to smash my PB from last year ๐Ÿƒ. Leason learned, overtake before it gets to narrow.
