Mathematicians Solve the Topological Mystery Behind the "Brazuca" Soccer Ball
KentuckyFC (1144503) writes "In the 1970 World Cup in Mexico, teams used a new kind of ball called the Telstar made from 12 black pentagonal panels and 20 white hexagonal panels. This ball has icosahedral symmetry and its own molecular analogue in the form of C60, the famous soccer ball-shaped fullerene. In 2006, a new ball called the TeamGeist was introduced at the World Cup in Germany. This was made of 14 curved panels that together gave it tetrahedral symmetry. This also had a molecular analogue with tetrahedral symmetry among the fullerenes. Now teams at the current World Cup in Brazil are playing with yet another design: the Brazuca, a ball constructed from six panels each with a four-leaf clover shape that knit together like a jigsaw to form a sphere. This has octahedral symmetry. But here's question that has been puzzling chemists, topologists and..errr...soccer fans: is there a molecular analogue of the Brazuca? Or put another way, can fullerenes have octahedral symmetry? Now a pair of mathematicians have finally solved this problem. They've shown that fullerenes can indeed have octahedral symmetry just like the Brazuca, although in addition to hexagonal and pentagonal carbon rings, the ball-shaped molecules must also have rings of 4 and 8 carbon atoms. The next stage is to actually synthesis one of these fullerenes, perhaps something to keep chemists occupied until the 2018 World Cup in Russia."
Which ball is the best for the players?
Personally I prefer the Telstar.
If builders built buildings the way programmers wrote programs, then the first woodpecker would destroy civilization.

It looks like every world cup but perhaps a couple has had a different stitch pattern on the ball. Is there really that much need for innovation? I think it might be cool to have a "better ball" but doesn't the sport at some point lose something from the equipment changing so frequently? Comparing stats when the balls have different characteristics like how smoothly they'll roll, air resistance etc must be the explanation for soccer riots.

Best mockery of the 2014 World Cup logo - EVER!
Also quite accurate for the Brazil-Germany, errr, match.
The game is called FOOTBALL, not "soccer". Now that you -in the USA (you were good enough in the Mundial, as my national team Greece was, congratulations)- start to learn about it and realize that it's played mostly with the ball in the foot... stop calling your rugby "football" (change it to something like, e.g., American rugby) and start calling football by it's name: FOOTBALL
(and it's time to adopt the metric system...)
Simple. He'll run around the lumbering heart attack who won't be able to move as fast thanks to inertia. Besides, the "play", such as it is, in American "football" stops every 5 seconds, I doubt your 300 pound piece of spray cheese can run much longer than that.

Even though they never actually run for very long on the field, they still have to be able to pass a fairly strict standard in training. They want guys that they don't have to worry about, because what they're doing is strenuous and dangerous, and they will still have to worry about them — if only as assets. If you put futbol players in a handegg game they would be fucking evaporated. If you put handegg players in a futbol game most of them would be fairly cumbersome, but any "accidental" contact would still be likely to result in a futbol player injury.
Don't get it twisted, handegg players are amazing athletes, even the ones shaped like a brick.

Damn, I was hoping this was about a bra bazooka.
I can't see those 8 member flat rings being at all chemically feasible. I really don't think this is possible to make as a carbon molecule.
Aromatic rings need to have 6 or 10 electrons in the delocalised orbitals, so an 8 member ring is going to need to have some other elements/groups to be at all stable...
The article quite correctly calls the ball a football and never mentions the word 'soccer'.
and it still won't help Brazil HUEHUEHUEHUEHUEHUE JAJAJAJAJAJAAJAJAAJAJAAJ LOLOLOLOLOLOLOLOL
(for you old farts out there, those are all "lol" in different ... languages ...)
You forgot the all important kkkkkkkkkkkkkkk that Brazilians use
In an article about a breakthrough in molecular topology, I'm currently seeing, while browsing at 2,
-7 comments about the relative merits of the soccer balls that inspired this discovery,
-6 comments condemning sports fans in general and soccer ball buyers in particular,
-4 comments whining about the fact that the U.S. doesn't have the same regional dialect as the commenter,
-1 terrible almost-pun,
-1 comment that is completely incoherent and incomprehensible,
-1 complaint about religion,
and a grand total of 1 comment about molecular topology. Is is too much to ask that we could have some comments from posters who are interested in, you know, math and science? Here I was getting ready to dredge up all that symmetry and topology that got drilled in to me in grad school. Oh well.
I can appreciate that being a US-based board, /. isn't filled with soccer fans, but still, why all the poo-pooing on innovation? Does the newest iPod really do anything predominantly different than its predecessors? How about that Galaxy V versus the III? Saying the Brazuca and Telestar are the same is like equating the 15-inch CRT that came with your Hewlett-Packard to the current 32" flatscreen you're sitting in front of. They both let you see what your surfing, right?
As a fan and recreational player who spends about six hours on the pitch every week here in Soccer City, USA, I'm impressed with the Brazuca. The ball flies truer (or at least more consistently), reacts livelier off the foot, and, as a previous poster noted, feels much different when you get hit by it. I know this is anecdotal, but I'd argue these things matter to those that play/are interested/care. Just because you're not interested or it doesn't impact you, doesn't mean the innovation and change is bad. I don't see the value of an iPad/tablet, but I can appreciate that it's an approach that others appreciate and an approach that continues to be refined.

OK ... so mathematicians proved you could have molecules with a symmetry similar to a new fangled soccer ball.
Is this good? Is it not good? Is it useful in any way? Or it this purely an intellectual exercise?
I'm afraid I don't grok chemistry with fullness, so I don't know if different symmetries give us different materials, or prettier chemicals.
I know shape usually defines the other kinds of bonds it can make, but I have no idea if this specific thing is of any benefit to anybody.
Can anybody give a lay summary for what the practical applications of this tidbit of knowledge actually are? Because I've got nothing solid here.

Simple. He'll run around the lumbering heart attack who won't be able to move as fast thanks to inertia.
And then when he's 2 meters past, he'll suddenly fall to the ground and clutch his leg.

You clearly don't understand the rules of the game then. A 300 pound guy is on the line in the NFL. If he's on defense, by running around him, you helped him get into the backfield to get the ball carrier. If he's on offense, good job getting around him, now you have to tackle a 240 pound guy with the ball.
I know NFL linemen aren't the healthiest men in sports, but I assure you that with the amount of money moving around the sport, they are the best at what they have to do.

There's already an American League Championship Series, and it's the championship of one of the two conferences in Major League Baseball. Its winner plays the winner of the National League Championship Series in the World Series. Any ideas for new names for the World Series that aren't biased toward the American League or National League?
crap, you're right
I wonder if any of these shapes are found in the pit of modern nuclear weapons.
IIRC reading about the Fat Man devices the explosives/lenses were the shape of a conventional soccer ball, which as it turns out is sub-optimal.
I am very small, utmostly microscopic.
One of the very, very few times I've ever seen on /. where I wouldn't call this off-topic. I'm mystified as to why anyone decided soccer/footballs should be compared to molecules in the first place.

Has this got to do with the article? Or the OP?
Indeed, what the actual fuck are you smoking? And where can I get it?
Yesterday was also the 52nd anniversary of the launch of the Telstar-1, the world's first active telecom satellite, the world's first privately-ventured space-faring mission and first commercial payload into space. http://www.nasa.gov/topics/tec... PS: Does anybody else find it weird that Telstar and Death Star not only are phonetically similar, but look eerily so as well?
