Migration of my SCIENCE ePortfolio to Blogger + A brand NEW post!

Hi! This is my official movement of blog from Live@Edu to Blogger. I haven't been writing for a long time and I heard that we have to update at least 10 science blog entries! That's a LOT. Now, I'm very busy all this while. As such, I will not say a lot about complex, complicating and confusing science stuff. Let's start with the basic things, how about the reviews about the newest South Africa FIFA World cup Official Ball, the Adidas Jabulani.

I don't know whether, you have heard about the positive and negative effects about the ball's aerodynamics. It was said that the 'techy' ball was constructed using a new design, consisting of eight (down from 14 in the last World Cup) thermally bonded, three-dimensional panels. These are spherically molded from ethylene-vinyl acetate (EVA) and thermoplastic polyurethanes (TPU). The surface of the ball is textured with grooves, a technology developed by Adidas called Grip′n′Groove that are intended to improve the ball's aerodynamics.


However, there are critics complaining about the ball's unusual 'long flight' time while in the air. It sort of ' glides' when it's given a hard kick. The flight trajectory thus becomes much longer than usual. This is primarily due to the GripnGroove technology used on its surface. Adidas have added little ridges that surround the ball in many circular shapes that can clearly be felt when holding it. Like the dimples that surround a golf ball, GripnGroove’s function is to improve how the ball passes through air; basically it enhances how aerodynamic the ball is.\


Here's a quote by a soccer player:
 "My problem was that the Jabulani held up in the air longer than I have ever experienced with a soccer ball. Every time I tried to take it out of the air, it would end up landing several yards past where I expected. Another great aspect to the Jabulani is the fact that it doesn’t have noticeable panels keeping it together. I am sure at some stage, you will have played with a 32 panel ball, and you will be familiar with how you can feel the gaps in between each panel. Well, with the Jabulani, each panel has been pieced together and thermally bonded, so that you don’t get the same gaps in between panels. This leaves the ball a lot smoother, and is another key component to why it moves so fast."

So, with the new ball out for the World Cup, many 'oily hands' incidences has dawned on a few goalkeepers. One of them is Robert Green, the England goalkeeper who let the ball in even though it didn't have much power.
