Here’s a mind expanding video explaining siteswap. Interesting to see someone explain the mathematics of juggling movements, while someone else is doing it, when what they’re doing looks _ **totally impossible.** _

That whole Gandini Juggling vimeo account is a goldmine, they’ve put a DVD’s worth of material up for free. I really have no hope of learning any of it though 😕

thanks 💕 i’m very much not a video person so it’s very hard to watch a 50min one for me, but I will send this to my mom that I somehow really got into juggling math (with this book that I lovingly recommend: [The Mathematics of Juggling | Burkard Polster | Springer](https://www.springer.com/gp/book/9780387955131))

I stumbled on a video demonstrating ‘negative siteswaps’, where balls are thrown back in time. It’s done with ‘antiballs’, which cancels out when it meets a normal ball…
[ ](https://www.youtube.com/watch?v=_5Q4UhyajC4)
" When a ball changes from going backwards to going forwards in time, it looks like a ball and an antiball appear out of nowhere and are thrown as a [multiplex](https://juggle.fandom.com/wiki/Multiplex). Both of these are actually the same ball; one is the ball going forwards in time, and the other is the ball going backwards in time. The antiball comes from the future, turns into a ball, and goes back into the future, so it doesn’t exist before that time as a ball or as an antiball. When a ball changes from going forwards to going backwards in time, it looks like a ball and an antiball come together in a [squeeze](https://juggle.fandom.com/wiki/Squeeze) catch and disappear. The ball comes from the past, turns into an antiball, and goes back into the past, so it doesn’t exist after that time as a ball or as an antiball."

As well as great performances there’s a lovely discussion in here about differences / correspondences between jugging and music improv:

A nice summary of siteswap from a mathematician: [Juggling Talk Summary](http://www.solipsys.co.uk/new/JugglingTalkSummary.html?JugglingTalk)
