Second hand. Jerking counter-clockwise.
Elias shrugged and began the geometry lesson. The students were brilliant, unnervingly so. They solved Euler's formula in their heads. They corrected his minor slip on edge count before he could finish the sentence. But by the twenty-minute mark, he noticed something wrong. The clock on the wall—a plain, battery-operated school clock—was ticking backward. classroom76x
The key turned with a sound like a sigh. Inside, Classroom 76X was ordinary to the point of sterility. Fluorescent lights hummed a flat F-sharp. Grey desks, twelve of them, faced a chalkboard that had been erased so thoroughly it looked powdered with dust from another decade. The lesson plan sat on the lectern: Period 3 – Advanced Geometry. Review Euler's formula for planar graphs. Second hand
