About Karmela Padavic Callaghan
What is Ultracold?
Ultracold is a longform newsletter that publishes on a weekly schedule. It reflects my experience as a queer, non-binary, immigrant physicist and science writer living, learning and working in New York.
Longform essays publish on the last Monday of each month, a media and diet roundup publishes mid-month, and every other Monday features a short essay at the intersection of science, writing, queerness and culture.
My headshot is by the talented Sylvie Tamar.
