## Juggling By the Numbers59

theodp writes "The BBC News' Laura Gray reports on a juggling notation system developed in the 80's called Siteswap (aka Quantum Juggling and Cambridge Notation) and how it has helped jugglers discover and share thousands of new tricks. Frustrated that there was no way to write down juggling moves, mathematician Colin Wright and others helped devised Siteswap, which uses sequences of numbers to encode the number of beats of each throw, which is related to their height and the hand to which the throw is made. 'Siteswap has allowed jugglers to share tricks with each other without having to meet in person or film themselves,' says James Grime, juggling enthusiast and math instructor for Cambridge University. Still unclear on the concept? Spend some time playing around with Paul Klimek's most-excellent Quantum Juggling simulator, and you too can be a Flying Karamazov Brother!"

Actually, the Juggler 3D screensaver is fairly popular at home (it's an X screensaver, maybe there's a Windows equivalent). I'm not sure if it uses the same numbering system, but it always indicates a string of numbers in the upper left to describe the particular juggling pattern being shown.

About 20-some years ago, my martial arts instructor (who is now 87) decided that I needed to learn how to juggle. Nothing fancy, just three balls.

It also was a great source of amusement for my daughter when she was little. I could juggle and she'd

Depends if you really lack motor coordination skills. What it sounds like is you either have your left and right confused or one side of your body is doing the work for both sides.

Much like BlackPignouf, it took me a month of daily practice to learn how to do the standard three cascade, and having been through that, I've found it very easy to teach others how to do it. (Probably, familiarity with a whole suite of failure modes helps.)

I persisted with juggling, and had a lot of fun with more complicated patterns, pass juggling, and so on. But it is all a case of directed persistance overcoming a complete lack of any natural ability.

Four is a lot harder... I found (and still find) four harder than five, since juggling four in a cascade pattern is basically juggling five but "passing the gap" — making sure that the gap, where the fifth ball should be, is harder for me than actually having that fifth ball in place.

A very useful (as much as any juggling is "useful"...) technique for four is to learn to juggle two in each hand simultaneously, in both rotations and in columns. Asynchronous columns of two balls in each hand (no pun

What he means is - don't juggle four in that way! Juggle four by doing two in each hand, in a vertical plane parallel to your shoulders, the throws happening asynchronously. It's *way* easier than juggling 5, and similarly *way* easier than juggling 4 in a 5 pattern with one missing. These SiteSwaps with 3 help a lot:

If just for the sake of juggling four, or as the basis for tricks with five, then sure — as a means of progressing to a five ball cascade, I'm not sure that would help at all? For me, that was great for co-ordination training for three in each hand, but not as something on its own. But I guess everyone juggles for their own reasons!

The original complaint was that four is a lot harder than five. This is manifestly false.

On the other hand, if your target is to get to five, then I *still* think it's faster to learn a four fountain, then learn simpler tricks with four, then learn some SiteSwaps with four, then move to working directly on five, rather than working just on doing five.

Yes, different people have different reasons for learning, and different people will learn best in different ways, but trying to do four in one of the harder

In all modesty, I think I became a very good juggling teacher. I taught a few hundred people how to juggle, and it took anywhere from 2 minutes (really) to an hour.
Anyone can do it, and you really got to begin with the basics (that is, with one ball, going from L to R and R to L).

For the beginner, don't use balls as you'll always be chasing the dropped ones. Use bean bags, or three hackey sacks. Start off holding two in one hand, one in the other. Throw one of the two into the air and, as it begins to descend, throw the one in your other hand into the air and catch the first one. Repeat. In the beginning you'll notice a tendency to throw them away from yourself, and walking forward trying to catch them. Try to keep your throws close to your body. When you catch one, that's called

Siteswap notation helped fuel a revolution in "numbers" juggling (more than 3 objects).

That's not always the best thing to do. For example, 45141 is a ground state three ball SiteSwap, one of my favorites. If you write it as 51414 it's not longer possible to go directly into it from cascade.

The idea that creating the right language can make such a difference may be dismissed as obvious by the /. audience who are familiar with this effect in programming languages.
But it shows the power of having someone look at a problem from a new or unusual perspective. In this case a mathematician managed to encompass most of the act of juggling in a simple expression. It must be incredibly satisfying to get an Eureka moment of this magnitude.
