This is Scientific American's 60-Second Science, I am Steve Mirsky. Got a minute?
With the World Cup soccer tournament underway in South Africa, a couple of things for the science-interested audience to watch for. First, the games will feature a new ball, called the Jabulani, the Zulu word for “celebrate.” And some players think something foul 1 is afoot. They contend that the ball doesn’t behave the way a normal soccer ball should, that it even turns the wrong way in mid-air. Adidas, which makes the ball, claims that the players complaining all have contracts with Adidas’s competitors.
The Sports Technology Research Group at England’s Loughborough University designed the ball. The sections aren’t stitched together anymore. Instead, the seams are glued or heat-sealed. The group leader, Andy Harland, told the Telegraph newspaper, “We have created a ball that is almost perfectly 2 round, and more accurate than ever before.” Well, millions of soccer fans will ultimately decide the latter.
Also watch for the effects of altitude. Some of the games in South Africa will be played at elevations 3 over a mile high. Which could make catching 4 one’s breath the primary goal.
Thanks for the minute for Scientific American's 60-Second Science. I am Steve Mirsky.
- Take off those foul clothes and let me wash them.脱下那些脏衣服让我洗一洗。
- What a foul day it is!多么恶劣的天气！
- The witnesses were each perfectly certain of what they said.证人们个个对自己所说的话十分肯定。
- Everything that we're doing is all perfectly above board.我们做的每件事情都是光明正大的。
- Weight of the crust changes as elevations are eroded and materials are deposited elsewhere. 当高地受到侵蚀，物质沉积到别的地方时，地壳的重量就改变。
- All deck elevations are on the top of structural beams. 所有甲板标高线均指结构梁顶线。
