The Beauty and Mathematics of Juggling | Alexander Leymann | TEDxDresden

Theoretical physicist and juggler Alexander Leymann explains and demonstrates how jugglers use mathematics to describe, communicate and generate new juggling patterns. He introduces the site swap notation for juggling patterns, where throws are represented by numbers according to their height, or more precisely by the number of beats that a thrown ball spends in the air. This way of describing juggling patterns is extremely useful, since as Alexander demonstrates there are certain rules how to change a given sequence numbers and thus create a new pattern. Alexander Leymann is a theoretical physicist at the Max-Planck-Institute for the Physics of Complex Systems in Dresden and a passionate juggler.
Alex has performed and taught juggling since the age of 14. One of his favorite juggling styles is the classic 3-ball juggling since this allows for an endless number of variations and a dance like levity. He also is an ambitious combat juggler, which is a form of martial art, where the aim is to hit a juggling club out of your opponents pattern while being in control of your own pattern. Furthermore, Alex has attended juggling conventions and organized combat events for many years. These get-togethers are an important part of the juggling scene to exchange tricks and engage in friendly competition.
As a theoretical physicist Alex is working in the field of semiconductor lasers and non-equilibrium Bose-Einstein condensation. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx

This creates a bunch of incredibly interesting signal processing problems. Very fun stuff. For example the triangle wave at 2:00 has a bunch of odd harmonics, however if he spun the balls quickly as he threw them they would curve through space instead of making a straight line. This would require extra energy input and thought, but it would filter out some of the odd harmonics in the signal he's making.

4:25 he's such a good sport in dropping. You can see the initial disappointment then the immediate positive mindset he has with the "three tries" mindeset. This is super cool!

Non jugglers might not realize how good a juggler this guy actually is. To hold a 5-ball pattern like that takes a large time investment.

Sehr geil, Alex. In Gedanken sehe ich Deine ersten Versuche mit 3 Bällen noch vor mir. Aus einem Sport Mathematik zu machen oder umgekehrt beeindruckt mich sehr. Kenne ich nur vom Bridgen so -- lach. Ich werde mich gleich mal über meine 3 Apfelsinen hermachen. Barbara

@@neelvanhoof2463 dit was mijn antwoord:
De berekening:
0+300=300, dus op 300 komt weer een 300 etc.
En 2+3= 5 dus op plek 5 komt weer een 3 etc.
En 3+3=6 dus op plek 6 komt weer een 3 etc.
En je moet kijken of alle getallen op elkaar uitkomen. Dus als de 300 weer op 300 uitkomt en 12 weer op 12 en 3 weer op 3betekent dat dat de getallen elkaar niet gaan verstoren. Dit betekent dus dat het een patroon is dit komt omdat er drie verschillende cijfers in dit patroon zijn en deze getallen zijn deelbaar door 3 daarom komt deze goed uit.
