Mathematician based in Heidelberg, Germany. Making research math visible -- how we think - what we do - how math works. (she/her)

One of the great joys of my adult life has been realizing that I can just pick up a new skill every so often, take a fun little class in it weekly for a year or two, and simply enjoy meeting people and getting medium proficient and not attempting to become professional in it at all!

From quantum physics to robotics, Lie groups are invaluable to science and engineering. Now, a new collaboration led by Yale University's Yair Minsky is merging representation theory, geometry & randomness to reveal new insights into the mathematical structures: https://bit.ly/4z1zz1K #math #physics

New Simons Collaboration Will Explore Discrete Subgroups of Lie Groups

Mathematician Yair Minsky will direct a Simons Foundation collaboration studying the mathematical structures, which are invaluable to modern physics.

this is pretty wild, #iTeachMath + #MathSky ♾️ i include below a screenshot of the Abstract the first result concerns work by Henry Cohn, who finished his 3 weeks of lecturing at PROMYS (Boston Univ.) yesterday. some good reading material for his flight back to PROMYS UK! openai.com/index/ten-ad...

Open AI has published some new mathematical results, solving some important conjectures: cdn.openai.com/pdf/ten-proo...

So yeah, this remains true in the age of AI as it has always been: as Euclid (probably apocryphally) said to King Ptolemy I, “there is no royal road to geometry”. You can't just buy your way into being a mathematician with a 200$/month “pro” subscription: you need work … •15/16

This is probably evident from my work - but I like to struggle and I think it’s the most important thing. It teaches us everything. We struggle, we make discoveries, and we surprise ourselves along the way…

„Ich werde jetzt einen Präzedenzfall dafür schaffen, dass wir endlich mit diesem Neutralitätsnarrativ aufräumen“, erklärt ein mutiger Lehrer aus Sachsen-Anhalt, der im Unterricht die AfD kritisiert und dafür jetzt sogar vor Gericht zieht. Es gibt keine Neutralitätspflicht gegenüber Rechtsextremen!

(S+) Wie der Lehrer Max Heckel gegen die AfD kämpft: »Es gibt keinen Mittelweg. Man muss Widerstand leisten«

Max Heckel kritisierte vor Schülern die AfD und wurde abgemahnt. Der Lehrer aus Sachsen-Anhalt wehrt sich dagegen. Ausgerechnet die Frau des AfD-Spitzenkandidaten im Land ist seine Kollegin.

While the Fields Medal celebrates the under-40s, the mathematician Joan Birman has, at the age of 99, solved a major open problem in representations of the Braid groups, a topic she has worked on for more than 60 years.

“Nature has learnt that the NSF has now pulled back $300 million from two of its divisions: mathematics and physical sciences, and computer and information science and engineering.” It seems the money is being used to fund AI ‘grand challenges’. If you’re sure AI can ‘solve maths’ this is sensible.

Oh yeah, and if Kratsios gets his way the US government won't fund life science research or universities anyway. Nature story: www.nature.com/articles/d41...

At the panel on “AI for Mathematics”, the top rated question from the audience is “Do you expect fewer young people to pursue mathematics in the coming years? What advice would you give to students considering whether to pursue PhDs in math?” (from Joshua Wang) #ICM2026
