Isometric Science Concept Diorama Grid

A clean 2x2 concept model infographic is presented against a soft, light-colored background, showcasing four independent, suspended, isometric viewpoint 3D model panels, rendered in a beautiful 3D illustration style.{argument name="theme" default="science"} The branches feature soft gradient colors, glossy materials, gentle ambient lighting, delicate shadows, rounded futuristic shapes, and high detail. Top left: Biology, a lush biological laboratory island with a giant DNA double helix tower at its center, complete with an arched glass greenhouse, spiral staircase, cascading organic paths, greenery, flowerbeds, and fluid biomimetic structures; the word "BIOLOGY" is integrated into the platform's leading edge. This section is surrounded by four small biological-related icons: a microscope, a DNA symbol, a sprouting plant, and a circular cell or petri dish symbol. Top right: Physics, a cool-toned high-tech energy laboratory section with a central luminous platform, a circular accelerator ring, copper-like electromagnetic coils, a staircase leading to the core, a display screen with waveforms, and a futuristic industrial base labeled "PHYSICS"; four surrounding physics-themed icons are added: an atom, a horseshoe magnet, lightning, and a broken-line waveform. Bottom left: Chemistry (CHEMISTRY), a modular molecular research structure in purple and silver, consisting of a ball-and-stick lattice framework, laboratory pillars, beakers, flasks, and a luminescent crystal core; the platform is prominently labeled "CHEMISTRY" on both sides. This section is surrounded by four chemistry-related icons: two molecular structure diagrams, a pair of laboratory test tubes or flasks, and a small burner. Bottom right: Astronomy (ASTRONOMY), a rocky lunar observation island with crater terrain, a domed observatory, a telescope, stairs carved into the rocks, and a circular cosmic background; the leading edge is labeled "ASTRONOMY". This section is surrounded by four astronomy-themed icons: a ringed planet, twinkling stars, a small rocket, and a new moon. The four sections are evenly distributed in the quadrant layout, each with its own soft geometric background shape. A unified soft color scheme is adjusted according to the discipline, and an advanced gpt-image-2 style is used, making each concept feel like a collectible miniature world. No people are included in the image, and there is no additional text besides the four subject labels.
