The screen glitched, then displayed a scanned image of the exact page. But the text was moving. The P-h diagram was animated. The compressor efficiency formula rearranged itself into a riddle:

Here’s a tale for you:

Arjun had been searching for hours. His final-year engineering project—a solar-powered miniature cold storage unit—was due in 72 hours, and he was stuck on the refrigerant flow rate calculations.
