Dr. Arjun hated e-waste. Not the moral kind—he just hated losing his place in a PDF.
He didn’t explain. Instead, he grabbed a breadboard, a 9V battery, and a red LED from his junk box. Following the hand-drawn schematic, he built a light-pulse sensor. At 11:47 PM, the LED flickered.

She sent a question mark emoji.
Twenty minutes later, the ancient lab printer coughed out 413 double-sided pages. Arjun stapled them into three sagging volumes. He wrote on the cover of Volume 2: MIMS – Opto & Magic .
He did.
He typed back: Yes. But I’m reading the hard copy.
