EXHIBITIONS IN 2013

From sunset to sunrise

Marko Raković author. Gallery of NHM, Mali Kalemegdan 5, January 2013

As the creatures of sunlight, human beings gather almost 80% of information on outside world by eyesight, so under the cover of darkness they generally feel powerless, scared and disoriented.
In contrast to humans, numerous animals not only cope quite well during the night, but it is in fact the period when they are dominant due to the extraordinary development of their other senses, primarily hearing and smell, or ability to move with help of echolocation. Some of them are undisputable masters of the night.
Life cloaked in darkness, only anticipated by humans from sporadic strange and unknown, sometimes even scary, sounds and noises coming from the nearby forest, scrub and riverbank, as well as from barns, attics and cellars, led to appearance of a whole array of folk beliefs, myths and legends pertaining to nocturnal animals.
The exhibition “From dusk to dawn” reveals the reason why the previously diurnal animals have chosen the secret nocturnal life during their evolution, leading to rise in their special abilities.

Minerals of Trepča

Author: Aleksandar Luković Gallery of Natural History Museum, Mali Kalemegdan 5 From June 2013.

The ore treasures of Trepča were already known by Ancient Romans, as evidenced by presence of an oil lamp recorded in old underground mines. In addition to Trepča, Romans have also exploited other ore-rich beds in this region, i.e. Srebrenica, Kopaonik, Gračanica, Sočanica etc. It is interesting to note that construction of fortresses in Ibar valley was financed by silver collected in this particular mine, and it was also used in production of first Serbian silver dinars (in 1412, according to ordinances by despot Stefan Lazarević).
Primarily known as a colossal bed of lead-zinc ore, Trepča is characterized by a very diverse mineralogical composition. There are over 60 different minerals recorded at this site, from main carriers of metals, such as sphalerite, galenite, chalcopyrite, pyrite, arsenopyrite, plumosite, jamesonite, to carbonate calcite (famous throughout the world due to its variability of forms), dolomite, rhodochrosite and certain rare minerals such as ludlamite. Due to eye-pleasing quality of their crystals, many minerals from Trepča found their place in museums throughout the world.
The collection of minerals from site Stari Trg – Trepča is one of the largest and certainly most beautiful collections within the Mineralogical Collection of Natural History Museum. The visitors of this exhibition will be introduced to fascinating examples of mineral associations, including large mineral druses, huge calcite curtains and beautiful minerals of the carbonate group.

Black and White – A story about chocolate

Authors: Desa Đorđević-Milutinović, Olga Vasić. From December 2013.

Although chocolate is a product of human knowledge, experience and skill, its origins are in nature. All the ingredients, directly or indirectly, come from nature, both from plant and animal kingdom, and chocolate unites them all. The main raw materials, cocoa and cocoa butter, are collected from seeds (beans) of cocoa tree (Theobroma cacao) which is still growing wild in tropical areas of America. The other important ingredient, milk, is a product of milk glands of cows, which have appeared through domestication process from now extinct wild ancestors, while some related species are still present in the wild. The base for milk secretion is plant food, most commonly various species of grass but also many other herbaceous plants. Fruits, seeds and chili pepper also originated in species or varieties of wild ancestors.
Chocolate is therefore another example of fine cooperation between humankind and nature. As a pleasant and easily available source of enjoyment, chocolate is also a close to experience and easily understandable evidence that humans are acquiring absolutely everything from nature, whether directly or indirectly. Therefore it is necessary to reminiscence on this fact repeatedly and through proper examples influence the humankind on the necessity of proper relationship with nature and conservation of its diversity.
