Very cool opportunity to make differentiable physics models for EPRV, work with Ben and co, and live in a cool place. Pretty much a dream job, apply!
Very happy to advertise a Postdoctoral Research Associate in Exoplanet Science position with me and Christian Schwab at Macquarie University in Sydney.

We'll be working on applying machine learning & differentiable physics models to extremely precise radial velocity surveys.

The sheer joy I felt just now discovering that there is a new Dan Foreman Mackey video about JAX.

I still feel like differentiable models are under appreciated, it’s like a magic super power for interpretability and extensibility. Maybe LLM-assisted coding can bring autodiff to more science teams? Still a mental leap to adoption.

Everything becomes so much easier when you can forward model your data

Looking back on this talk about autodiffable spectral models, there is still so much promise, I’d love to see what folks have been up to in this space!

Currently 83% carbon-free energy in Texas right now:
- 40% wind
- 33% solar
- 10% nuclear

Wholesale prices are negative, and 3.5 GW of batteries are charging.

Despite headwinds, over 20 new EVs are coming to the US market in 2026, including several more affordable vehicles. Can any thrive without federal tax credits? insideevs.com/news/782572/... 🔌💡 🔌🚗
Over 20 New EVs Are Coming In 2026. These Are The Seven I'm Most Excited About

It’s wild that stellar limb effects start to matter at non-negligible fractions of a resolution element on the ELTs!
Challenge… or opportunity!?

Get outside into a dark place if you can tonight - no guarantees, but a possible brilliant display of the northern lights.
We have upgraded our geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm.

Current predictions suggest that the activity will result in potentially the largest solar storm to hit our planet in over two decades.

"Nearly all important discoveries pass through a stage of neglect or obscurity,” Professor W. Grylls Adams went on to explain. “Either the public attention is already preoccupied, or the discoveries come at a time when the public are not prepared to receive them".

Big congrats to Jennifer Burt, Xavier Dumusque, and Sam Halverson on finishing their epic (instant classic) Annual Reviews of Astronomy & Astrophysics article "Precise Radial Velocities"!
