Planet 9 might be our Ultima Thule . Hell would certainly be freezing over at 700 AU. Whether this tentative observation is Planet 9 or not, it is still an interesting observation and an example, I think, of proof that AIs will not do all our science for us. (At least not LLMs).
As I’m sure you’re aware, rivers usually combine together to make larger and larger rivers until they reach the sea.However, there are some exceptions: rivers do sometimes split up and flow in separate directions. These splits are called “bifurcations” (bi” meaning “two”, and “furcations” being the forks). They happen…
What AI-optimized schools misunderstand about learning
Continuous glucose monitoring has been a thing for a while. It's a probe that sits just inside your body and measures blood glucose levels frequently. Obviously this is most useful for type 1 diabetics, who need to regulate their blood glucose manually.
I recently returned from the 2025 Annual Meeting of the “Localization of Waves” collaboration (supported by the Simons Foundation, with additional related support from the NSF), where I…
Stephen Wolfram investigates the discovery of structures since the Game of Life was invented--searching possibilities versus invention by explicit effort. A thorough look at oscillators, modularity, glider guns.

Can We Terraform the Earth Using Life Itself?
INTRODUCTION TO DIGITAL FILTERS WITH AUDIO APPLICATIONS
UPDATE: I submitted a more formal version of this article to the UMAP Journal (Undergraduate Mathematics and Its Applications), which publishes articles that use mathematical modeling for real-world problems, often with a pedagogical or expository angle. A preprint is available on arXiv at…

Whale songs were first noticed by accident, when analysts tracking Russian submarines at the height of the cold war heard cetacean interference instead. An engineer sent some recordings to Roger Payne, a biologist friend of his, who did something that proved pivotal: he played the hours-long recordings on his hi-fi at…

Whether you believe in preventing damage (the core aim of the aging field, though that's not the focus of this post) or treating damage as it arises, our current best efforts in both treatment and mechanism selection haven't yielded promising results. None of the approved drugs for age-related diseases reverse any…
Designing a cheap two-port vector network analyzer with good measurement accuracy.
Transit time of 6,600 years; that long ago, around 4,600 BCE, the state of human civilization was devoid of technology. Hard to imagine what would happen back home on Earth during a journey of that length.
The what is connected to the when.
