Truly excited about today's preprint @UniStavanger: 👉 https://t.co/qE5tkk6Wr7 With W.A. Horowitz (@UCT_news) we solve a 190 year old #mechanics problem: develop an #action principle for #nonholonomic systems relevant for #robotics, autonomous vehicles & material processing.

A small step towards better Korean 🇰🇷 language skills by completing a beginner's course offered by #KoreaUniversity for graduate students & new staff. A heartfelt thank you to the team at the OIH our teacher Narae Kim and my fellow classmates. 재미있는 한국어 수업 감사합니다.

Observing the night sky & to marvel at its beauty is one of humanity's primal experiences. A delight to see the #KoreaUniversity Amateur Astronomical Association #KUAAA share their fascination with our campus community in their annual exhibition of excellent astrophotography.

🇰🇷 at the forefront of #axion research: laid out by SungWoo Youn, recently appointed head of new @IBS_media Dark Matter Axion Group #DMAG in his #KoreaUniversity colloquium. From early theory contributions (invisible axion) to world-leading strong field #haloscope experiments.

Another week, another interesting talk at the #KoreaUniversity 2025 Fall #Physics Colloquium. Today Sungwoo Youn (@IBS_media #CAPP) will tell us about the ongoing hunt for the axion particle, one potential candidate to explain the phenomena associated with dark matter.

„Gleichberechtigung bedeutet, dieselben Chancen zu haben, nicht dieselben Pflichten!“ Aha. 🫠 https://t.co/BsPezUdDcQ

Dazu kommt noch das neue "Staatsangehörigkeitsmodernisierungsgesetz" (StARModG), welches auf die "Ermöglichung der Mehrstaatigkeit" (@AuswaertigesAmt) abzielt. Diese darf nicht zur Ungleichbehandlung von Deutschen im Besitz "nur" des 🇩🇪 Passes führen.

Es ist für mich unverständlich wie im Jahr 2025 eine #Wehrpflicht nur für Männer beschlossen werden kann. Da Geschlecht in 🇩🇪 nach dem Selbstbestimmungsgesetz (SBGG) frei gewählt werden kann, sollte meines Erachtens der "Neue Wehrdienst" auch geschlechtsneutral sein.

A pleasure to present the action approach to initial boundary value problems and space-time symmetry conservation at the 2025 Mathematical Sciences Fall Colloquium at #UNIST, based on collaborative work with Jan Nordström (@liu_universitet @go2uj) & Will Horowitz (@UCT_news).

Honored to give one of the 2025 Mathematical Science Fall Colloquia at #UNIST today. A warm thank you to my host Yunho Kim from the Mathematical Imaging Lab for the opportunity. Great to learn more about progress in applied mathematics to benefit our work on quantum dynamics.

First visit to #UNIST (Ulsan National Institute of Science and Technology) today. The youngest of the four national research universities in STEM (w/ KAIST, GIST & DGIST) founded in 2007. Features expansive & well integrated campus nestled in gentle slopes of the Ulsan region.

Next up at #BARYONS2025, Juhee Hong (@yonsei_u) presenting her recent work on energy loss and suppression of heavy flavor mesons (B & D) in a thermal medium, relevant for understanding #heavyion collision experiments at @CERN & @BrookhavenLab.

A pleasure to listen to an interesting talk on recent results for nucleon interactions with heavy Baryons (Omega_ccc) based on the HalQCD #latticeQCD method presented by Tetsuo Hatsuda (@riken_en) at #BARYONS2025.

Very nice opportunity to catch up with György Wolf (Wigner RCP 🇭🇺) at #BARYONS2025 in South Korea 🇰🇷. Great to see the sustained collaboration between the nuclear physics communities in Europe 🇪🇺 (@NuPECCinfo) 🤝east Asia 🌏(#ANPhA https://t.co/iSgx3mRoSx)

Interesting talk by Yoshimasa Hidaka (@univkyoto @riken_en) at #BARYONS2025 on phases of nuclear matter. Suggests a "spaghetti" phase where chiral symmetry is restored but glueballs remain confined. Possible relation to our findings of a confining heavy quark potential at T>Tpc.

It was a pleasure to talk about "Tackling the Inverse Problem in PDFs form #LatticeQCD" at #BARYONS2025. Looking forward to transfer insight from work on spectral functions at finite temperature to the inverse Fourier transform vital in PDF extraction.

And we are on! Jun-Sik Yoo from the #KoreaUniversity Quantum Real-Time Dynamics group presents recent collaborative results (@LosAlamosNatLab) on precision scale setting in #latticeQCD at #BARYONS2025. Key prerequisite to exploit simulations as precision tools for nuclear physics

Any responsible country using nuclear ⚛️ medicine ⚕️or power ⚡️, one must consider the question of radioactive waste. Good to see dedication to the topic via the Korea Radioactive Waste Society, which holds her autumn conference at the same convention center as #BARYONS2025.

Early start at #BARYONS2025 conference, about to give a presentation in parallel track on "Recent developments in QCD". Excited to talk about the inverse problem in PDF reconstruction in #latticeQCD a new line of research at the #KoreaUniversity Quantum Real-Time Dynamics group.

Do not miss the next instalment of the 2025 Fall Physics Colloquium at #KoreaUniversity tomorrow. Junho Seo (@postech1986) will take you into the world of nano-machines in his talk on "Mechanical Oscillators for Quantum Technology" 👉 Tue. 17:00h Asan Science room 433
