Every machine in a Hospital that diagnoses your body without cutting you open is based on a principle of Physics, discovered by a Physicist who had no interest in Medicine.
If you think the world doesn’t need Basic Science, or that somehow Science has failed you, think again.

A bit late on the "vegetative electron microscopy" meme, but hey, it's the end of the semester, so it's also "vegetative Raman spectroscopy" and "vegetative responses to Reviewer 2" season. :)))

That day when I have to showcase the lecture and a colleague who I know is a) more knowledgable on the topic and b) younger than me decides to attend unexpectingly. I could really use less cortisol in my life :))

One of the reasons for profs. Haroche's and Krasz's visit was to present the joint appeal of 100+ Nobel laureates in which they call for the confiscation of all russia's sanctioned state assets which can then be used for the reconstruction of Ukraine.

Back from a seminar "Incorporating AI into university STEM curriculum", and got so. many. feels.
On one hand it was absolutely amazing to see the main auditorium packed (because u know, covid, then war) and the audience so visibly engaged.
On the other: i really can't stand the technobro vibe.

A crazy outreach idea, absolutely not cost-effective, but it got stuck in my head: a CSI-like real life mystery!
With like some invisible fluorescent ink, comparing diffent kinds of sand under SEM and collecting the Raman spectrum of idunnowhatever. And running down the corridors.

A lot of materials we study can be described as a "solid matrix X filled with liquid Y". As I was writing a recommendation letter with AI today I realized it has an opposite structure: a watery matrix of AI pleasantries filled with actual solid facts about the student. :)
