On What Do We Reckon?

On next summer? On our fingers? With a computer? Yes, but always with numbers.

Here you will learn how and why numbers came into the world. Visitors will discover a variety of number systems and methods of calculation on five-thousand-year-old Sumerian tablets, “on the lines” of medieval arithmaticians and in the binary number system of today’s computers.

Investigate numerical relationships in art and nature with your own eyes and ears: do our bodies reflect the golden ratio? Can you hear the harmonies in musical tones?
