Mathematicians Make Surprising Breakthrough in 3D Geometry with ‘Noperthedron’
The noperthedron has a surprising property—which disproves a long-standing conjecture

Kun kotimaa ei tunnu enää demokratialta | Maailmanpolitiikan arkipäivää
Kymmenet tuhannet israelilaiset ovat muutaman viime vuoden aikana muuttaneet pois kotimaastaan. He ovat kyllästyneet sotaan, turvattomuuteen ja poliittiseen epävakauteen. Maailmanpolitiikan arkipäivää -ohjelmassa tavataan Portugalista uuden kodin löytäneitä Israelin ja Yhdysvaltain kansalaisia. Heitä yhdistää se, että he katsovat kotimaansa demokratian olevan nyt henkitoreissaan. Coimbraan muuttanut Nataly Lavi sanoo Israelin olevan koko ajan vähemmän ja vähemmän demokratia. …

I find something profound in recursive descent parsing, both the idea of it and the coding of it. For me it's one of the more beautiful things in mathematics, let alone computing.

Sums of Exponential Terms, Conserved Quantities, and the Real Wave Numbers
There is consensus that sums $S_n={ {Σ}_{k=1}^n R_{0k} e^{i θ_k}}$ of complex exponential terms, despite their mathematical significance, only possess closed-form representations for specific values of n and special values of their parameters and that there are no generally-accepted recursive formulae for their computation. This note is focused on recursive formulae that: (1) provide closed-form analytic representations of $S_n$ for any finite n; (2) include generalizations of the usual formu…

Poisson Energy Formulation for Floorplanning: Variational Analysis and Mathematical Foundations
Arranging many modules within a bounded domain without overlap, central to the Electronic Design Automation (EDA) of very large-scale integrated (VLSI) circuits, represents a broad class of discrete geometric optimization problems with physical constraints. This paper develops a variational and spectral framework for Poisson energy-based floorplanning and placement in physical design. We show that the Poisson energy, defined via a Neumann Poisson equation, is exactly the squared H^{-1} Sobolev …

Researchers tested Google DeepMind's AlphaEvolve AI agent on 67 mathematical problems and found that it discovered improved solutions to about 20 of them (Adam Zsolt Wagner/@azwagner_)

Really happy to share our new paper on using AlphaEvolve for mathematical exploration at scale, written with Javier Gómez-Serrano, Terence Tao, and @GoogleDeepMind's Bogdan Georgiev. We tested it on 67 problems and documented all our successes and failures. 🧵
