World Cup Science?

What sort of science can we see in action in the World Cup?


What you do speaks so loudly that I cannot hear what you say.

Curling the ball.

However i believe there are behind the scene arguments because the new type of ball which they have chosen is uncontrollable .

I think any psychologist would have a lifetime's worth of work studing crowd dynamics and motivation.

I been watching the Sweden - Thrinidad-Tobago match. It is about half over. I Have noticed the new ball does seem to gather spin at some times when it is kicked. It bounces off the ground back to a player, bounces left and right, and it also sems to fly farther.

I do not watch much soccer so I do not know about the flight leingth. Nor can I tell if it curves right or left in the air, albeit Michael says it doesn't. Ill take his word for it.

I have seen the new pattern on the surface of the ball. SO - why was it changed and how in aerodynaics, does this new surface differ from the old?

Itís the pattern mouldings which are causing the problem.

Even though the ball is round the shape of pattern mouldings cause differences in the air flow past the ball making it very unstable in its flight if the ball is kicked hard and fast without a high spin rate to stabilise it.

 Basically it can fly straight for most of its journey and then suddenly curl to the left or right then fly straight again and then curl again due to one of the mouldings slowly turning in and out of the airflow ,making it impossible for anyone to judge where it is going to go .

Does the new patern alow for longer flight? Or is this jsut my imagination?

For some reason crowd dynamics has been a bit of a pariah in psy research although some has been done.

I was enjoying the Germany game the other day before friends whisked me off into the twilight zone...lol  Myself, I love to be a spectator while watching sports and I can tell you it doesn't matter which sport I have attended...there is nothing like watching it live!  I am sure there have been studies done...Hockey is a bit more violent and much more physical in the crowds and have watched people even fight in the crowds..unbelievable!  Baseball is like a choir doing the wave big time, but then the Baptists(sorry not to offend any of you here)but at games look at you crazy because you bring in your own alcohol in a bag disguised as a purse full of ice.  Daschund Racing everyone is laughing most of the time.  Pig racing...everyone is drunk and laughing. Okay, some of the sports are not national, but big deal, a sport is a sport!  Sailboats, a social event...just bring a picnic with some vin!  Basketball is like the crowds are dancing as it is very fast paced.Football, very physical as each play takes place...Soccer in crowds are the same way and just a bit more joyous as a goal takes place, Tennis, is reverent and so is Golf! Horseracing, oh wow!  I love this with the crowds people are on edge of their seats and screaming the whole time. I could go on here..but since I am an semi-expert on being a spectator at many sporting events...

Oh, for goodness sake, USA! 2-0 against you 6-minutes before half-time. I always support you at the World Cup if it's not England playing -- you need some inspiration to take the game more seriously. Actually, I'm supporting you even more with our current boring team. At least you recognise it *is* a team game!
