?? English instruction:

A normal pendulum swings back and forth Steadily and predictably.

But what happens when you attatch a second pendulum to it?

• What do you think, will both double pendulums move in the same way?

• Hold the longer pendulum and set the short one in motion.

Now let the longer pendulum go. What happens?

Based on his calculations in the field of astronomy, the French physician and mathematician Jules Henri Poincaré (1854-1912) posed the question if all physical phenomena are predictable. In his bestseller “Science and Method” (1912) he gave the following answer: „It is possible, that small differences in the initial circumstances lead to big differences in the results (…) prediction becomes impossible and we are left with a random phenomenon.“

Two people sit across from each other in the carousel, tossing a ball back and forth between them.

The rest of the group sets the carousel in motion. Try tossing the ball back and forth again.

• Where does the ball fly when the carousel is turning?

?? English instruction:

A long, heavy pendulum is set in motion. Stay a while, calmly observing the patterns it creates.

• Observe the movements of the pendulum, how do they change over time?

• How long does it take until the pendulum rests once more?

• Which basic shape can you recognize in the patterns in the sand?

In 1851, the French physicist Jean Bernard Léon Foucault (1819-1868) proved that the earth rotates using a pendulum of 67m length. In 1997, Imaginata repeated the experiment in the then-gutted ‘Uni-tower’ in Jena, earning a mention in the Guiness book of records. Today, the pendulum draws it’s patterns on the Imaginata’s own premises.
