- Given the weather today, it’s time to repost my favorite phase diagram: Nakaya’s snow crystal morphology. We are towards the bottom right today. 🧪 ⚛️ #cryoEM
- And this is when Bluesky became the old twitter
- While Cornell has field theorists, we also have practitioners
- Imaging hydrogen atoms with ptychography
- Jim West's group taught us everything we know about building ultra-quiet rooms
- Ducktober
- #cryoEM 🧪⚛️ Lena’s paper on imaging thick biological sections with STEM is finally published! We started this work almost 10 years ago. After Lena passed in 2023, I spent much of my sabbatical working with Yue and Steve to wrap this up. Also learned a lot about TEM vs STEM dose efficiency
- Some good news 🧪⚛️
- FUCK YEAH SCIENCE arstechnica.com/science/2025...
- Our new zippy ptychography code, PtyRAD is now out in print. 3D Multislice reconstructions that used to take a day, now can be done in about an hour! 🧪⚛️ #ptycho paper and install links: academic.oup.com/mam/article/...
- Our hands-on workshop on Electron #Ptychography ! ⚛️🧪 using our new fast python code starts tomorrow, Tuesday, July 8. Lecture Schedule is below, for folks who want to listen in on-line. We hope to post the tutorial and code walk through videos later. cornell.zoom.us/j/9512638476...

- Danielle was one of Lena’s students 🧪
- So the crazy thing here is the company this is supposed to be about is Corning. The company famous for its glass research. And the across the board metric is a measure of how similar individual atom positions are in their CRYSTAL structures. So much is nuts here, but that should have been a red flag

- USC vs MIT
- This has been going for a while. When I worked at Lumon, erm Lucent Technologies in the late 90’s this similarity was also noted, but that is was also inflamed. Still an improvement on the previous deathstar logo
