Relativistic jets, revisited
Rereading my senior thesis on decelerating relativistic jets — and what the fastest things in the universe say about drag.
First love. Astrophysics, dark skies, and the long view that keeps the rest in scale.
The Milky Way core from a truly dark site, camera on a tracker, nowhere to be at dawn.
The model my thesis argued with. Kept close, the way you keep an old sparring partner.
