To build out an eight-episode series, Schur and the writers played up the theft at the retirement home to create more room for clues, cliffhangers and the PI character, played by Lilah Richcreek Estrada.

He told me about a woman he met who said she had set up her business using guidance and motivation from a chatbot he developed called Pi.

By 1970, with a partnership in a successful PI agency and a stable and happy family, Easy Rawlins is a changed and contented man.

Classical computers have managed the calculation for molecules as large as pentacene, a chain of five hydrocarbon rings with 22 electrons in “pi” covalent bonds, which govern the molecule’s shape and reactivity.

That approaches but still falls short of the classically modeled pentacene and its 22 pi electrons.
