Metastatic disease accounts for the majority of cancer-related deaths. Tumors and their metastases form a complex network of interconnected cellular ecosystems. Could the framework of metacommunity ecology help us unravel this complexity? cell.com/iscience/fullt…

In the data manifold, the shortest path between two points is a geodesic that pass through high density regions of data. Just like mass curves the space geometry, data also curves the space. In the example below we can see a geodesic being optimized between two points. 1/3

New article: "The geometry of data: the missing metric tensor and the Stein score" (blog.christianperone.com/2024/11/the-ge…). I show how you can derive a (efficient to compute) data manifold metric tensor with the Stein score alone ! Deep connections to diffusion, score-based models and physics.

We often think of an "equilibrium" as something standing still, like a scale in perfect balance. But many equilibria are dynamic, like a flowing river which is never changing—yet never standing still. These dynamic equilibria are nicely described by so-called "detailed balance"

Even though Newton's laws are deterministic, the behavior of many interacting bodies is so chaotic that it looks essentially "random." Statistical mechanics effectively says: why bother with all those complex trajectories? Just go ahead and replace them with truly random motion.

🧵🛰️Las herramientas de teledetección como los radares y satélites son indispensables en la predicción a corto plazo, observación y en diferentes estudios climáticos y meteorológicos, ¿cómo funcionan? Lo explicamos en este hilo.

self studying, reading hard papers, going through unfamiliar equations/concepts, are all skills. they’re absolutely trainable. and just like other skills, they’ll go away if you don’t use them not getting frustrated when you dont grasp something for the Nth time is a superpower

Como físico cuántico os puedo asegurar que esto es una estupidez. Sin filosofía no hay ciencia. Apuntadlo en vuestro cuaderno y repetirlo día a día.

Chicos, no les quiero pinchar el globito, pero entender el entrelazamiento cuántico, las dimensiones adicionales y la superconductividad es mil veces más complejo, Y ÚTIL, que comprender lo que quiso decir un viejo pretencioso en una época donde ni existía la luz eléctrica

Stop whatever you're doing right now, Ed Witten and the IAS just dropped a new banger, an introduction to Chern simons theories and topology! Damn!

How did people describe the brain before computer metaphors? Charles S. Sherrington in 1942 called it "that enchanted loom where millions of flashing shuttles weave a dissolving pattern."
