From 13^th December 2012 the Museum features a new exhibition "Everything... is numbers". Its main goal is to show the fact that mathematics surrounds us in all aspects of life.

Numerous interactive stands presents different practical appliances of mathematics. Visitors may explore selected mathematical questions by his own activity, experiments and measurement. A single question is illustrated by a number of experiments. In the "geometrical" part of the exhibition, following topics will be presented: polyhedrons, projective geometry, mathematics in maps, mathematics for artists, the Pythaogorean theorem, fractals, topology, graphs, and conic sections. The "number" part will feature: mathematics in music, coding and digitalizing, encryption, playing with numbers, counting machines.

More than 60 different experiments will be available for visitors. They will take the role of a Renaissance painter studying rules of perspective, or a student of Pythagoras, using a monochord to learn mathematical rules of making music chords.

One of the most basic mathematic skills are the arithmetic operations: addition, subtraction, multiplication, and division. In the exhibition, it is possible to use forgotten instruments, like abacus or slide rule, or with pencil and paper, but also by unusal methods not taught in schools.

Another feature will be playing with mathematics – building magical squares, pyramids and cubes, making fractals, changing knots and finding solutions for the classical questions: a travelling salesman and bridges in Królewiec.

The significant major change in comparison with the previous exhibitions, but also comparing to typical educational interactive exhibitions, is the usage of original objects, sometimes very old, as mathematical tools: arithmometres, slide rules, other tools used to create mathematical curves and surfaces, planimetres or surveying and drawing tools.

The exhibition was created thanks to the financial backup provided by the Ministry of Science and High Education, the Leopold Kronenberg Bank Foundation, and the Goodyear Dunlop Tires company. The designer and curator is the certified custodian of the JU Museum, Dr. Maciej Kluza. The conceptual support was provided by the consultant team made of distinguished experts in popularization of mathematics, like members of the JU Institute of Mathematics Dr. Krzysztof Ciesielski and Dr. Zdzisław Pogoda, and employee of the JU Pedagogical Study, the board member of the Mathematics Teachers Society and Methodological Advisor to the Municipality of Cracow, Dr. Anna Widur.

Visuals and graphics were projected by two graduates of the Academy of Fine Arts in Cracow – Katarzyna Skawińska and Kamil Łęcki.
