A 2x2 grid of 4 large mathematical symbols built as intricate pop-up paper engineering sculptures emerging from an opened book: - [Top Left: The Integral symbol (∫) as a towering paper archway, cut-paper strata, and printed equations as microtext wallpaper] - [Top Right: The Sigma symbol (Σ) as a folded paper museum structure with sharp origami cantilevers, dramatic shadow play, and technical diagram callouts] - [Bottom Left: The Pi symbol (π) as a layered cardstock classical gate with weathered ink textures and tiny paper silhouette pedestrians] - [Bottom Right: The Klein bottle silhouette as an impossible folded paper sculpture with visible paper tabs, fold creases, and paradox geometry] Tabletop editorial studio photography, macro shallow depth of field, tactile paper grain and fibrous textures, visible bookbinding seams, inked technical diagrams, clean Swiss grid layout, realistic miniature papercraft.
