This week's #Fiddler: Assign distinct prime numbers to the vertices of a dodecahedron so the sum of the vertices of each face sum to 2025. I modeled this as an integer linear program. Here is one possible solution. @xaqwg.bsky.social

This week's #Fiddler: what is the minimum-energy way to pack 9 particles in a unit square, where energy is measured as the sum of 1/dist over all pairs of particles?
Turns out it's NOT a regular 3x3 lattice! @xaqwg.bsky.social
