This led to the so-called 'tau–theta' problem: [13] what seemed to be the same particle (now called K +) decayed in two different modes, Theta to two pions (parity +1), Tau to three pions (parity −1). [12] The solution to this puzzle turned out to be that weak interactions do not conserve parity. [7]
This article covers computer software designed to solve, or assist people in creating or solving, chess problems – puzzles in which pieces are laid out as in a game of chess, and may at times be based upon real games of chess that have been played and recorded, but whose aim is to challenge the problemist to find a solution to the posed situation, within the rules of chess, rather than to ...

The solver must partition the grid into rectangular or square regions according to the following rules: [1] Every partition must contain exactly one symbol in it. A + symbol must be contained in a square.
The theta meson (θ) [1] is a hypothetical form of quarkonium (i.e. a flavourless meson) formed by a top quark (t) and top antiquark (t). As a P-odd and C-odd t t state, it is analogous to the ϕ (s s), J/ψ (c c) and ϒ (b b) mesons. Due to the top quark's short lifetime, the theta meson is expected to not be observed in nature. [2]

Smith discovered a 13-sided polygon in November 2022 whilst using a software package called PolyForm Puzzle Solver to experiment with different shapes. [4] After further experimentation using cardboard cut-outs, he realised that the shape appeared to tessellate but seemingly without ever achieving a regular pattern.
