Scientists ponder how jugglers seem to defy limits to human reaction times | Ars Technica
Wow this is really fascinating. Incredible coordination and training needed.
The fastest expert jugglers can make nearly 500 catches per minute, which translates into just 120 milliseconds per catch—faster than human reaction times even in high-speed sports like tennis, in which a player typically takes 200 milliseconds to adjust their performance. The Guinness world record for juggling is currently 11 balls.
The accuracy required is a measure of how unstable and difficult a juggling pattern is.arstechnica.com
