A clean 2x2 conceptual entity model infographic on a soft light background, showing four separate floating isometric diorama tiles that personify branches of [science] in a polished 3D illustration style with pastel gradients, glossy materials, soft ambient lighting, subtle shadows, rounded futuristic forms, and high detail: - Top left: BIOLOGY, a lush bio-lab island with a large central DNA double helix tower, curved glass greenhouse architecture, spiral stairways, layered organic pathways, greenery, plant beds, and fluid biomorphic structures; the word "BIOLOGY" is integrated on the front edge of the platform. Surrounding this tile are 4 small icons: a microscope, a DNA symbol, a sprouting plant, and a circular cell or petri-dish symbol. - Top right: PHYSICS, a high-tech energy laboratory tile in cool blue tones with a central glowing platform, circular accelerator rings, copper-like electromagnetic coils, stairs leading up to the core, a monitor screen with waveform graphics, and a futuristic industrial base labeled "PHYSICS"; surrounded by 4 icons: an atom, a horseshoe magnet, a lightning bolt, and a line graph waveform. - Bottom left: CHEMISTRY, a modular molecular research structure in purple and silver, built from spheres-and-rods lattice frameworks, lab columns, beakers, flasks, and a glowing crystalline core; the platform prominently reads "CHEMISTRY" on two visible sides; surrounded by 4 icons: two molecular diagrams, a pair of lab test tubes or flasks, and a small burner. - Bottom right: ASTRONOMY, a rocky lunar observatory island with cratered terrain, a dome observatory, a telescope, stairs carved into the rock, and a circular cosmic starfield backdrop behind it; the front edge reads "ASTRONOMY"; surrounded by 4 icons: a ringed planet, spark-like stars, a small rocket, and a crescent moon. All 4 tiles are evenly spaced in a quadrant layout, each with its own muted geometric backdrop shape and cohesive pastel palette tuned per discipline, styled like collectible miniature worlds. No people, no extra text beyond the four discipline labels.
