THE GUARDIAN OF TIME
stainless steel 
From this place the guardian makes sure that every one entering the time museum lives in the present, leaving behind past and future.

The hand of this eternal clock shows always the right time to do things: NOW!
The word "now" is written in 53 different languages of the world. The hand itself carries a lot of scientific symbols. On top: 9192631770 means the number of periods of the atom 133Cs, to define 1 second. Then follows 365.256: the exact length of the year in days. The centre circle represents the Sun. Every 11,3 years the orientation of the magnetic poles change. The nutation cycle of the earth is 25765 years. On the lower part one finds the number 299793: with a factor of one thousand, in meter per second, it is the so called "speed of light". Above and below the Sun symbol are marks that define in the right proportion the distance of Mercury, Venus and Earth to the Sun. Other 5 marks define the Megalithic Yard: 1MY=82.35cm..

ALCHEMISTIC PLANETARY       Stainless steel.

In the middle ages astrology was an accepted part of science. In it certain chemical elements have been connected with the visible planets, the moon and the sun. These 7 objects have been arranged in a way that starting with the sun (1) going counter-clockwise three steps, one gets the days of the week (1-2-3-4-5-6-7). (see drawing on the left side).

ENERGY CONSERVATION LAW

Einstein's formula E=mc² means basically that energy and mass are equivalent. Things will change form, but nothing will be lost. To manifest it, in this work the small parts that have been cut off from the 4x4 square have been replaced below. 

About 2 billion years ago this place was situated at the equator. Tectonic shifts moved it here and turned it. It makes me feel that the time of the past is still present. To symbolize it this, a row of gold covered stones has been arranged. To connect symbolically the present with the past, the basic construction has a length of 20 meters, the wall itself has a length of 20 MY (1 Megalithic Yard = 0.8235m). Seven is the number of steps in natural cycles. There are 7 basic groups of animals, plants, stars. The table in chemistry is composed by 7 rows and 9 columns. The north line through the center divides the east line in the proportion 7MY by 9MY.

SUN OBSERVATION TOWER    Limestone, stainless steel tubes

At winter solstice from this point  the sunrise will be seen at 12.16 pm MET (= 12 o'clock local time),  between the lower gap of the Cheetah rock. At this time the sun is positioned exactly at south direction. Inside the upper part of the sun tower, stainless tubes are orientated towards sunrise and sunset for the four cardinal time points of the year: winter & summer solstice, and spring & fall equinox.

DRENA 3000

The holes inside the circle represent the stars midnight at summer solstice in the year 3000. Using the astronomical counting system "Julian-days", that moment is given with the Julian-number 2816958,4167. Local time will be 0 hours, 0 minutes and 0 seconds. Julian Day : Method of counting time continuously with days starting noon 1.1.4712 B.C. Introduced by Scaliger in honour of his father Julian.
