I guess neck cutoffs wouldn't happen unless there was some other kind of platform change - right? And, if you are able to model the cutoff process itself, combining that with the 'normal' planform evolution model gives you predictability beyond T.
Yep. Can’t wait to see high resolution DEM coverage in that part of the world

Well I looked at the actual map (always a good idea!) and it turns out that the low-curvature segment actually has a pretty high sinuosity. These are a couple of large, mature bends that migrate slowly. Shows how I still don't have a good intuition for reading these plots correctly...
Low sinuosity and *low* curvatures.
I think it just happens to be a segment with low sinuosity and curvatures. The correlation between curvature and migration rate is also the worst there as there is not much signal.
The fact that you have to ask means that the data viz is not good enough 🙂
"migration rates are a highly nonlinear function of channel curvature and they cannot be predicted"
migration rates:
Did some vibracoring over the weekend on the barrier island between the Gulf of Mexico and East Matagorda Bay, to study how barrier islands are impacted by hurricanes
3D-printable time: An evolving meandering river as a 3D model where time is the 3rd (vertical) dimension 🧪⚒️
Here is a piece of the Yazoo River:
Nobody told him that saying “we remain committed to serve all of humanity as best we can” doesn’t sound as good as he think it does
This does not mean that I am doing less work and less thinking and I am not learning. I am just able to delegate the more boring stuff to an assistant that knows more about coding than I do; and I have more time to think about more interesting questions and to explore more ideas.
I know that there a ton of significant issues with AI and the companies that are behind the technology, but this is an excellent writeup of how thoughtful use of AI tools can speed up scientific work. I have been using Claude Code since January and it has been incredibly useful.
Good to see 'segmenteverygrain' being used as the starting point for a model that reconstructs 3D grain shapes from 2D data onlinelibrary.wiley.com/doi/full/10.... ⚒️🧪
The trove of files released by the Department of Justice, illuminates Epstein’s deep interest and entrenchment in the scientific community.
But the files also underscore how he used his power and money in ways that kept women out of places where they might succeed. https://bit.ly/4qWgPLz
TFW you have to read a paper about sequence stratigraphy
I’m so confused. I thought it was the illiberal left that demanded safe spaces and used cancel culture to silence anyone who threatened to disturb their snowflake ideological purity. Can someone help me out here?

At least Watson and Shockley did contribute something significant to science. As far as I can tell, Pinker’s scientific papers haven’t really changed the field.
Among the many good friends of Jeffrey Epstein the one who infuriates me the most is Steven Pinker. I read “How the mind works” soon after it came out and I was impressed. I hate to think about how many years it took me to realize who this guy really was.
It’s pretty clear from the graph that I don’t pay too much attention to it 😁
Yes, some of the numbers on Strava are highly questionable
When the dot is above the gray zone: too much training; when it’s below: too little
So far in 2026, I have successfully stayed outside of the recommended weekly training effort ranges #running
If anyone’s opinion on AI can be trusted to have merit, it’s Terence Tao. 🧪⚛️🧮
This interview between two mathematicians is as awkward as you might expect it to be, but what they are discussing is a promising new direction.
Here is a notebook that contains all the code for two animations (the first one is the one above): drive.google.com/drive/folder...
I gave a talk last week at the University of New Mexico and one thing people seem to have remembered from it was this old animation that shows how migration rate depends on curvature in meandering rivers. It was created using Manim, a Python package written by @3blue1brown.com
This beautiful book by Stephen Welch explains really well some of the key concepts in ML/AI, often from a historical perspective. The YouTube videos are not bad either: youtube.com/@welchlabs?s...
Excited that this paper, led by former PhD student Natalia Varela (based on her dissertation), is now out!
We use the occurrence & characteristics of thin, silty turbidites from the Ross Sea to interpret Antarctic Bottom Water outflow since ~3.3 Ma.
