Hello people, don't feel !@#$%^&* okay? Every team goes through bad patches, even arsenal! and look how they beat Cardiff 4-0 (: so cheer up and train hard !
anyway since i am damn free today, here's a little bit of fun fact about the innocuous soccer ball:
In the past, footballs were made from inflated pig bladders. YES! inflated pig bladders, disgusting on so many levels. True, humans don't eat pig bladders, but i'm sure they are considered delicacies in some remote regions of the world, so you're basically playing with your food which will in turn annoy your mum real badly. Besides, think about the poor piggies! We can consume their flesh but think of how indignified they will feel in Rainbow Bridge when they see their mortal remains inflated and crudely kicked about. But that's not the point, as you can see we humans have evolved and now have specialised teams of engineers and scientists working around the clock to create the PERFECT BALL (:
Law 2 of Association Football states that all footballs must be air-filled spheres with a a circumference of 68-70cm, mass of 410-450g and inflated to a pressue of 8-12 psi. Modern footballs are stitched from 32 panels of waterproof leather/plastic: 12 regular pentagons and 20 regular hexagons. This 32-panel ball is a spherical polyhedron that is similar to a truncated icosahedron.
The ball is spherical only because the air pressure within cause the panels to bulge (: Can you imagine kicking a truncated icosahedron around? It will be so mathematical!
