“Sheldon,” Dr. Sturgis said, and for once he sounded breathless. “The gravimeter at the university’s geophysics lab recorded a 0.0019 hertz anomaly at 4:59 PM. Your AMR prediction was off by only 0.0001 hertz. That’s not a coincidence. That’s a discovery.”

Sheldon sat on his bed, staring at the AMR equations. Newton the salamander flicked his tongue.

She lowered her book. “Come again, sugar bean?”

“AMR calibration, Dad. Please don’t touch anything. Your body heat creates micro-eddies in the air pressure.”

That’s where Meemaw came in. Sheldon found her in the kitchen, drinking coffee and reading a romance novel.
