Generate a scientific aesthetic flowchart on Maxwell's Equations derivation with deep blue (#1E3A5F) main color, copper (#D4A76A) accents, and ivory (#F5F2E8) background. **Layout:** Vertical timeline with horizontal branches. Key nodes in radial symmetry. **Nodes:** 1. Experimental laws (gear+magnet icon, hand-drawn border) 2. Math tools (abstract ∇ shapes, smooth lines) 3. Four equations in scroll-style with gold highlights 4. Breakthroughs (lightning icons with glow) **Connections:** Gradient fluid arrows for main flow, dashed arrows for feedback loops. Add ripple effects from light speed formula. **Enhancements:** Subtle particle texture, 15% opacity grid, 7% opacity manuscript fragments in background. Title "The Pathway to Maxwell's Equations" in serif font over field line sketch. **Style keywords:** Scientific historical narrative + Neoclassical illustration + Electromagnetic symmetry.
