71 numbers on a round wall
I installed 71 numbers of  high-grade steel on a round wall. All  numbers, except the first, are digits of the wellknown in science number e = 2,718281828459... The connection of a Pi-defined wall with a horizontal line, that is formed by "e" was the obvious thing to make because of the brilliant formula, that was created by Euler: e exp (i*pi) = – 1
 

2 glass objects
In the grass you can see two glass squares with somthing inside - a sphere in the first one and two channels in the other one. The sphere creates interference pattern by a mirror - a dynamic form appears. The crossing channels give a static form between the roots of the tree and the technical channels of the building.
 

5 glass squares inside the building
Scientific data and fundamental scientific works were transformed into visible structures using the software programm THE MAGIC PIWORLD by JVS. Each of the squares is a glass sheet 133 x 133 cm fixed on the wall.
 

PSE: 69 696 red squares show the chemical properties of 112 elements. The digits define the color of the square.

M33:  The 258 716 digits of the prime number M 33 = 2 exp 859433 - 1, found in 1994 by David Slowinski and Paul Gage, are written in 458 rows and 565 columns.

π : The first 75 492 digits of the circular number Pi were transformed into ellipses and arranged in 699 rows and 108 columns.

e:  The first 718 281 digits of  "e" were transformed into a trace.

const: Extracts of fundamental scientific works by Aristoteles, Kopernikus, Kepler, Darwin, Freud and Einstein were transformed into a new script.
