U.S. Science Is in Chaos
Last year Christopher Reynolds started to worry that his space telescope was going to be killed. The mission had started taking shape nine years earlier, a billion-dollar orbiting observatory that would look back in time into the early universe to study the first black holes, the formation of galaxies, and more.

Show HN: High-Res Neural Cellular Automata
The NCA operates on a coarse lattice of cells (in this example vertices of a mesh). Center: A sampling point (Point) (red dot) inside a triangle primitive, whose vertices correspond to NCA cells (State_i,,State_j,,State_k). The local coordinate (u(Point)) expresses the point’s position inside the primitive, while the locally averaged cell state (bar{State}(Point)) is obtained by […]

Why do commercial spaces sit vacant?
In yesterday’s mailbag post, Matthew Yglesias responded to a question about why commercial spaces sometimes sit vacant for years at a time. Matthew’s answer started off on the right track, then veered off course. So, as one does, I quickly fired off a note in response. That note went (and is still going) more viral […]

Wolfram Language and Mathematica Version 15, AI Assistant, Symbolic Music, More
An Impressive Release for Modern Times June 23, 1988 is when we launched Version 1.0 of Mathematica. Today—almost 38 years later—we’re launching Version 15 of what—in recognition of how far it’s expanded beyond “math”—we now call Wolfram Language. It’s an impressive release, with a lot of new core functionality. It might perhaps seem surprising that […]
