today i learned about the square cube law from one of my students - which says "When an object undergoes a proportional increase in size, its new surface area is proportional to the square of the multiplier and its new volume is proportional to the cube of the multiplier."

also i learned the reason that cells are so small is because of the square-cube law. "when a cell increases in size, its surface area-to-volume ratio decreases," so they're just the right size, no larger!
