Hi there,
I'm ali from Switzerland (german speaking part).
Juggling software is an interest of mine and i might create some threads about projects/ideas soon.

I'll be at the next swiss juggling convention.

Over the past decade there has not been so much innovation any more with juggling probs. In the near past people like Matty, Kilian and others have experimented with lighter club handles and Henrys now is producing carbon fiber handles which make juggling clubs lighter in weight and thus easier to do long runs of juggling or to juggle more objects. Now Luke Burrage has developed a hyperboloid shape for club handles and made a 30 minutes video where he explains the why and how:

I wish he would provide the source files from his experiments so that others could try to tweak them to their liking and maybe a new club handle comes widely available.

Are there any more developments like this with juggling probs that you know of? Can we have the sources of those experiments be in the open, that we can innovate all together and learn from each other?

Juggling Lexicon

Hey everyone! I'm starting a project to document juggling terminology and its variations across languages. However, I only know a smattering of the juggling terms used in languages other than English, so I would love some support with the project. "Terms" includes not only names for tricks and patterns (cascade, fountain, backcross, scorpion kick), but any term that jugglers use (flash, qualify, cycle, grip, club).

I'd like to include as many languages and as much depth as I can, including differences within the same language (alberts/body throws/crotch throws, everies/ultimates/1-count). Any contributions would be incredibly valuable!

Hi everyone!
I’m Seba, a juggler from the Italian-speaking part of Switzerland. I love improvising with three clubs, manipulation, and losing myself in repetitive patterns and five-club endurances. I also enjoy trying and training with other props.

I’m currently part of a small group of people organizing a little convention in my region, the Ticino canton (Switzerland).
I will soon add our convention to the calendar (it will probably take place on 25, 26, 27 April, the weekend right before the ACDC – A Convention De Celleno in Italy).

Glad to be on the Juggling Edge!

Hi everyone! My name is Bonnie. I’m a hat juggler living in Hawai’i and the lead organizer for the Hawai’i Island Jugglefest.
We just had our festival last weekend and it was super fun! My goal next year is to win the club balance competition (I got 3rd place again). I also want to get better at passing :) It’s nice to meet you!

Hi all,

My name is Anton and I am currently working on getting my 5 clubs back to being solid! I might go to the EJC this year as its quite close being in Holland...

Juggling Equations

I've been looking at juggling through a more mathematical lens than I usually do, and I've found some interesting relationships. The variables I'm going to use are as follows:
S- siteswap value
P- Period
X- start location in the pattern (ex. x in any period 3 pattern is 123)
D- End location in the pattern (ex. D in 531 is 321)
L- the number of times something 'loops' through the pattern (ex. the 4s in 441 loop once, the 1 doesn't loop). The mathish way to say this would be S mod P, but it makes more sense here to just say L. (Note: L can also be based on a value that isn't S)
W- the number of times a throw crosses the right 'edge' of a pattern, including after it 'loops'. This number can be similar to L but is NOT the same.
O- the number of objects in a pattern.
I- (If the font doesn't distinguish, this is an i, loop is an l) The total 'distance' a throw travels in the pattern. (ex. in 441, I is 111.)

That's a pretty good heap of variables. Using these and some logic, we can define some relationships. I'm going to use # as a summation sign, meaning the sum of all of that value in a given pattern. For example, #S of 531 is 9. I hope that doesn't mess with the hashtag system... On paper, I use a capital sigma like in math.

First of all, the one everyone knows:

O= (#S)/P

Which gives you the number of objects in a pattern.
We can also say that

I= S-LP

because -LP essentially takes the loops out of a siteswap value, leaving only the smallest possible value, which is what I is.
A helpful way to check validity is to see that there are as many of each D value as there are of each X value. Translation: each throw has exactly one start and one end. Because of this rule, we know that

#D = #X

But the most important relationship I've found is that

WP+D = S+X

which I got to via experimentation and logic. I don't really remember all of it, but trust me. (I think if you try to find a way to get from S to D mathematically, this is probably what you'll come to.)
Anyway, now that we have these relationships, we can substitute some of them together. For instance:

WP+D=S+X --> WP-S = X-D
--> #W P - #S = #x - #D
--> #W P - #S = 0 (not object number, value zero)
--> #W P = #S

P behaves a little bit strangely, but best I can tell, summing it does nothing because it's one value throughout the whole pattern. Questionable logic, I'm aware.
But we can then take that equation and see that

#W P = #S --> #W = (#S)/P
and therefore:
#W = O (Object number, not value zero)

and that's the basics. In summary,
O=(#S)/P
#D=#X
WP+D=S+X
#W=O

The following gets crazy and probably hard to follow:
And now, for a stranger and more theoretical equation. It can be used to convert siteswap values into state values, and it is pretty janky.
Here is some notation I will use and other details:
- Each value in a pattern can be treated as a set of values. For 441, S= [441], X=[123], W=[111], L=[110], and so on.
- A subscripted number can be used to indicate what item of a set is to be used. for example S₃ of 441 is 1. When a variable is subscripted, each value of that variable is used to create a set with one more 'dimension'. Single value--> list --> matrix --> so on.
- There's a mystical magical set that I usually call psi, but on the computer I will use %. %=[123456...]
- A range of values can be indicated in a subscript like so, S_1~4, meaning that values 1 through 4 of the set are to be used.
- A different base value for L can be indicated using //, example L/X+3/. (For any period 3 siteswap that would be [120] because X+3=[456])
- S_t is a state value. State is notated by giving the position of each object. For example xxox would be 124.

With that out of the way:

S+X-P(L/S+X/ - %_1~L/S+X/)= S_t

Which took entirely too much time to find. But we can also rewrite that as

S+X-PL/S+X/+P%_1~L=S_t
and
I+X-P%_1-L/I+x/=S_t

I use 'music rules' for this, meaning you only define L the first time you use it, unless it changes. Also good to note that for some reason, the P% in one is positive and in the other is negative. I think that has to do with L being based in different numbers, but I honestly don't know. I'm a bit too tired to find out at the moment.
Anyways, if you read through that, really really well done. I struggle to understand some of this sometimes, and it's far far cleaner on paper. These are the most refined siteswap to state conversions I have found so far (there are others but I don't like them as much). If you find an error in the math part of it, that would not surprise me, but they work as far as I can tell. Further testing required I suppose.
Anyways. There's that.

("cleaned" versions of the equations:)
S + X - P (L_/S+X/ - %_1~L) = S_t

S + X - P L_/S+X/ + P %_1~L =S_t

I + X - P %_1-L/I+x/=S_t
