Three Little Pigs

The story of the Three Little Pigs is a timeless tale of how important good planning and doing things right is. Also, it serves to remind us that good architecture and engineering is key to one’s survival. A key aspect of the story is how the wolf “huffs and puffs” to blow the straw house and the stick house away. However, he cannot blow the brick house away as it is too well-built. Out of scientific curiosity, how hard does the wolf have to blow to destroy the Little Pigs’ three houses?

An experiment was performed to scientifically test this tale. The researchers built a house out of straw, a house out of sticks and a house out of bricks, then set up a fan to test at what wind speed the house was destroyed. The straw house blew away when the wind speed was 11m/s. The stick house lasted a little longer, up to a wind speed of 21m/s. Then what about the brick house? The brick house withstood winds of 35m/s, whereupon the researchers had to stop as the strong wind nearly blew the people away.

Reed

Can you describe a reed that sways and bends to and fro in the face of wind as strong? Most people associate the word “strong” with something like a tree that stands tall and grand, never bowing to the will of the wind. However, the reed teaches us the important lesson of the strength of flexibility. When a storm strikes, what is left behind are not strips of reed but smashed pieces of wood.

A rigid tree appears strong because it stands so tall and does not move, but in the face of strong winds the opposite happens. As a tree does not bend much, it must face the full force of the wind and ultimately the tree snaps when there is sufficient force. On the other hand, the reed flows and bends in the direction of the wind, deflecting the force away. Not only that, but a reed has both flexibility and elasticity, meaning no matter how much they are bent and beat down, they can stand back up. Ergo, flexibility is stronger than rigidity. Skyscrapers use this concept and they are designed to sway on a windy day. The philosophy is also adopted in martial arts, with deflecting a strike to the side being a far more effective defence than taking the force of the strike directly.

Flexibility has far greater implications than withstanding the wind or a strike. The most important example is personal relationships. A person who never bends and sticks to their opinions may deem themselves “tough”, but they are in fact just a stubborn idiot drowning in a pool of arrogance. Sure, if it is a very important debate then you should stand your ground and state your opinions, but in a normal conversation it is just foolish to angrily state that you are right and never back down. It is far wiser to be flexible like a reed and meet the other person halfway, bending slightly to see their opinions and reach a peaceful agreement. If you stand tall like a tree you will end up standing alone on the same spot forever, but if you can bend to the other person’s flow like a reed, you can have a healthy relationship with them and co-operate. If both sides bend a little for each other, then they can have a smooth conversation and be able to establish co-operation, understanding and solidarity. Flexibility makes both you and the other person happy and allow for co-existence – something that is inevitable in human societies.

The tree may tease and mock the reed for its apparent helplessness and docility against the wind, but after the storm has passed, only the reed still stands. Remember this: instead of ignoring another person’s views and repeating the same words over and over, listening carefully to the other person and being flexible and tolerant is a far wiser and braver act. A wise man is someone who possesses the wisdom and benevolence of being flexible like the reed.
