Instructions:

Place the oloid on the inclined plane and observe it’s movements.
• Which parts of the oloid’s surface touches the ground when it rolls?
• Observe the oloid exactly; can you see a circle or a square in it?

The artist and technician Paul Schatz (1898-1979) discovered this shape and
described many technical applications based on it’s unique movements while
rolling. These include use in ventilation systems or in mixers for homoeopathic
medicines.

Instructions:

Two players sit across from each other, neither seeing the other players ‘building site’. Each player has a set of building blocks. Build a shape out of the blocks that your partner can’t see. Give your partner instructions for your shape, without speaking. Can your partner succeed in recreating your shape?

• First, start with three or four different shapes
• How often must you play to understand each other well?
• Which ‘words’ do your ‘language’ have?

In accord with the sentiment ‘if you can’t talk about it, you don’t belong’, language is an effective tool for social exclusion. Even scientists from every discipline are occasionally accused of explaining actually simple concepts and facts with unnecessarily complicated (mostly Greek or Latin) terms. Thus, it is hardly surprising, that the doctrine of the hidden transmission of information also has a technical term: steganography.

?? 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.

Put the toy blocks into the mirror book and change the angle by adjusting the relative position of the mirrors.

• Look into the Mirror Book. At which angle must the two mirrors be so you can see your face properly?
• Open the book to a right angle and put the toy blocks into it. How many mirror images can you see?
• Now close the book slowly; at which angles can you see complete mirror images?

Since ancient times, “mirror” (lat. speculum) has been a term for a collection of texts used for orientation and reflection of one’s own life circumstances.  Well known is the “Sachsenspiegel”, for example, in which Eike von Repgow first recorded the legal knowledge of the Middle Ages in writing.
