Emily scanned the five problems on her screen, her mind automatically categorizing them by difficulty and time required.
Problem 1: Quantum entanglement calculations with multiple particle systems. Standard graduate-level work. Fifteen minutes, maybe less.
Problem 2: Special relativity applied to particle decay in accelerated reference frames. Tricky coordinate transformations, but manageable. Twenty minutes.
Problem 3: Statistical mechanics of phase transitions in exotic materials. This would require careful thought. Thirty minutes minimum.
Problem 4: Quantum chromodynamics calculations involving quark interactions. Advanced particle physics. Forty minutes if she was efficient.
Problem 5: ...
Emily stared at the fifth problem, and recognition hit her like cold water.
