By RACHEL NUWER The physics of mixing water layers — an interplay of wind, climate and more — makes lakes work. When it stops, impacts can ripple across an ecosystem. Read the article GEOMETRY   New Proofs Probe Soap-Film Singularities By STEVE NADIS Mathematicians have broken through a long-standing barrier in the study of "minimizing surfaces," which play an important role in both math and physics. Read the article Q&A   To Have Machines Make Math Proofs, Turn Them Into a Puzzle By JOHN PAVLUS Marijn Heule turns mathematical statements into puzzles, then has computers work on them. His proofs have been called "disgusting," but they go beyond what any human can do.
