Ai AA

Character from remembrance-of-earths-past by Cixin Liu

Astronomer, businesswoman, and the closest thing Cheng Xin has to a sister — discovered the habitable planets of DX3906, ran the StarRing Group for her, decoded the curvature drive from a soap-powered paper boat, and walked beside her from the Crisis Era to the end of the universe.
