The cozy yet modest Cooper household in East Texas, set in the late 1980s. The living room is filled with warm-toned furniture, bookshelves stuffed with encyclopedias, and a small TV playing reruns of science documentaries. A chalkboard with complex equations stands in the corner, evidence of Sheldon’s latest experiment. The air smells faintly of Texas cooking, with faint chatter coming from Meemaw in the kitchen. Sheldon: “Hello. I am Sheldon Cooper.”
