#Exhibit of the Month

One of the great technical achievements that revolutionized the idea of time and space, opening a new era in the history of communication, is telegraphy. It is based on the transmission of electrical signals through a cable over long distances, allowing people to communicate instantly. The telegraph spread very quickly and a network of wires stretched around the world.

In 1837, the American painter and physicist Samuel Morse invented the first electromagnetic device for telegraphy, patented in 1840. To send messages by wire, Morse developed in 1838 a simple code of dots and dashes, which represented the letters of the alphabet, known as "Morse code ".

Both Morse code and the telegraph machine were improved over time, with the telegraph becoming the most widespread system of communication and information transmission for more than a century, until the advent of the Internet. The telegraph system consisted of a series of stations repeaters along the transmission line route. Each station had an operator who received and transmitted messages by telegraph. The Morse machine transmitted about 25 words per minute, which were recorded in code on a paper tape. The operator in charge of transmitting the message would decode it and write it on paper using a special typewriter.

In Bessarabia, the telegraph entered in 1860: on April 8, the Bender telegraph station began its activity, and on April 24, the one in Chisinau, following the construction of the first Odesa-Chisinau-Leova telegraph line. Currently, telegraph services have been discontinued. The only ones who still use coded communication are radio amateurs.

The Morse telegraph machine shown comes from the Osinoostrovsky electrotechnical plant, Soviet Union, and dates back to 1934. The exhibit was restored by Mihail Culașco.

Exhibition of models

2 - 28 February 2012

The exhibition of models on a reduced scale is organized by the Association of Modelers of Moldova and is an attempt to recreate such events, being the first of its kind after a very long period of time.

People have very different passions: anyone collect stamps, others - butterflies, weapons, coins, and so on. But there is another kind of passion, which is called the modeling. This is the technique of making copies of machines and equipment at a reduced scale.

Many people consider that modeling is an occupation for children. However, prominent modelers disagree with this statement. The modeling is a noble passion, like collecting stamps, coins, etc., and quite expensive.

It is hard to believe how accurate some copies of real objects are. There are replicated even the smallest and most insignificant items, such as electrical wiring, hydraulic components, pipes, and even people, all of which are tens of times smaller than in reality. Similarly, there are imitated the influences of weather and climate on military equipment, traces of exploitation in different parts of the world, so that, for example, there is well seen that the tank fought in a desert environment, that an aircraft was exploited intensively, but another one was recently made.

The exhibition includes a large number of models (over 200) of different sizes, made by experienced and novice modelers from the country. Here one can see models of military and civil engineering, aircraft, warships, and fantastic devices as well as dioramas that reflect the different situations from life. In the future, it is expected to hold two exhibitions of this kind a year.
