The closest the field has come to solving the planar unit distance problem, first proposed in the 1940s, was in 1984. Now, OpenAI claims an internal model has cracked the puzzle.

For years, quantum computers have carried a bold promise. They could solve problems so complex that even the world’s best ...

Researchers have found a faster, more accurate way to design magnetic “bottles” that hold plasma for fusion power. Using symmetry theory instead of traditional, slow Newton-based calculations, they ...
