Man Copies the Creator's Design..
How is it that paper-thin electric lighbulbs can withstand strong pressure when pushed or screwed into a lightsocket ? According to the book How in The World ?, the answer lies mainly with in the bulbs shape, which is based on the " eggshell principle."
Even though eggshells are very thin, the eggs are not crushed by the weight of the female bird when she sits on the nest to incubate them. This is because the shape of the egg provides structural strength that withstands the pressure. ( Thicker shells might not allow the check to peck it's way out. ) Copying the Creator's design, lightbulbs have a rounded profile so that when gripped , the force is " transmitted in all directions away from the point of contact by the curve of the glass."
Thus , as with the egg, excessive stress is not placed on any one point, and the bulb does not break. Man has learned so much from studying creation !
