Efficiency is all about doing more with less using the least resources, time, or energy to get the best results. From Aristotle’s curiosity about shapes to Zenodorus’ studies on polygons, mathematics reveals that circles and spheres are the most efficient 2D and 3D forms, maximizing area or volume for a given perimeter or surface. Nature echoes this wisdom: bees build hexagonal honeycombs to store honey and nurture larvae with minimal waste, and snowflakes crystallize in hexagons for strength and beauty. Understanding these principles helps us optimize space, design smarter, and solve real-world problems more effectively.
