“Relax,” said the professor-apparition, adjusting his tie. “It happens. Every semester, someone tries the PDF. And every semester, I have to give the same lecture. Now, get your notebook.”
At 2:17 AM, he woke to a strange smell. Not smoke. Knowledge. Like burning sandalwood and old paper. The screen glowed without being plugged in. The PDF was open, but the text was… moving.
For the next four hours, Professor Sarkar (or his spectral residue) taught Arjun about calorific values, bomb calorimeters, the chemistry of methane explosions, and why a good fuel must balance cost, availability, and pollution. He made flames dance in the air to illustrate laminar vs. turbulent combustion. He turned the wall into a giant Moody chart for fluidized bed combustors.
Arjun screamed, fell off his chair, and knocked over a stack of assignments.
“Why are you doing this?” Arjun whispered, genuinely moved.
He hit search.
The first three links were malware traps. The fourth led to a grainy, scanned PDF where page 47 was a blurry thumbprint, and page 112 was missing entirely. “Good enough,” he muttered, and fell asleep with his head on the open laptop.
The equations of stoichiometric air requirements rearranged themselves into a glowing flowchart. The diagram of a pulverized coal burner began to rotate in 3D. Then, a small, spectacled man with chalk dust on his tweed jacket stepped out of the screen.
