Hello new followers! You probably found me because of the pets starter pack. So let me pay the pet tax up front. This is Emmy, one of three of my three esteemed colleagues. Tune in to learn about the cool science we do. Supercomputers, supernovae, and neutron stars are just some of what we work on!
The halting problem is easy actually. The program will terminate when the computer breaks. Duh.

500 days— that’s how long Ash & Willow have been waiting for the right family. Can you help us find them? Learn more at crits4cats.petfinder.com

Our number one Christmas wish is for our wobbly cats Ash & Willow to finally have a forever home, after more than a year in our rescue. We know placing cats with special needs can be hard but we promise these two are worth the wait. Learn more about them & apply at crits4cats.petfinder.org

Slowly coming to terms with the fact that I'm not a science account that posts cats. I'm a #cat account that sometimes posts about science.

Absolutely thrilled to announce that I'll be part of this collaboration. I'll be moving to Ann Arbor to collaborate with Michigan facility on exciting projects involving supercomputing, AI, and fusion power.
This has been in the works for a long time, but now the move is a few months away!

Paper day! This is a fun one if you like low level #hpc #programming hacks. 🧪🔭
In computational physics ⚛️, we often interpolate tabulated data that spans many orders of magnitude. A common way to do this is to tabulate in log space. But logs are slow... Or are they? 🧵👇

Not-Quite-Transcendental Functions For Logarithmic Interpolation of Tabulated Data

I have interacted with undergraduate students who have never used anything other than a phone or tablet and don't know how to navigate a filesystem. The way most people interact with a computer is just different now, much as I am sad to admit it.

Haven't seen this posted on here yet: applications for the 2025 LIGO International Physics and Astronomy (IPA) program for educators are open until the end of January!
It's a fantastic* program for high school educators:)
*(and I'm not only saying this cause I helped with it back in 2019😆)

Absolutely devastated to discover I've become the kind of person who likes to work on vacation. Because no meetings or bureaucratic nonsense means it's way more productive and enjoyable.

General Relativity is the Dynamics of Distance
We know that gravity is the same as acceleration. General relativity tells us that this means gravity is the warping of distance.
