Mathematical Reverie by the Window

In a cinematic realistic scene, a young woman with wavy reddish-brown hair sits alone at a wooden coffee table, leaning against a large glass window. The warm golden sunlight gently shone on her face. She rested her head in her hands, gazing out the window, her expression calm and deep. The image is shot from outside the café through glass, featuring soft reflections, slight out-of-focus blur, and a slightly blurred background that creates a dreamlike atmosphere. Mathematical formulas in the style of white chalk hand-drawn float on the window glass, as if she were pondering these things: integrals, limits, algebraic formulas, quadratic charts, trigonometric identities, and E = mc². These equations appear light and translucent, artistically arranged without covering her face. The overall tone is intellectual, introspective, and calm.
