We can't define anything precisely

jtotheizzoe:

Get hypnotized by this wave pendulum … seriously, I can’t look away.

A wave pendulum like this is built of equally weighted objects suspended by different (and carefully calculated) lengths of string. Released simultaneously, their differing periods (frequencies of oscillation) cause them to form a “wave” image together that cycles through all possible patterns. 

It’s mind-boggling. Looking for a science fair project? This would be a great one.
