HALO EARTH at the Copernicus Science Center
Why do we need to communicate with others so much? Does the Internet really bring people together? How to let potential inhabitants of space know about yourself? We invite you to the premiere of the latest film produced in the Planetarium "Heavens of Copernicus". "Hello Earth" will take us to the world of our ancestors and to the unknown corners of space. We follow them in the wake of space probes carrying an earthly message across the universe.
The desire for contact with another person is one of the earliest and strongest human needs. We learn to speak through relationships with others. This ability is with us throughout life and is the most natural way to communicate. What language did the first people speak? In fact, these first modes of communication can hardly even be called speech. The easiest way is to compare them with what little children articulate. First, they make all sorts of cries, then individual syllables, and finally, they learn words and whole sentences. The evolution of speech - the increase in the number of words, the formulation of complex sentences, the use of abstract concepts - made it possible to accurately convey more and more complex information. Thanks to this, there was an opportunity for cooperation, the development of technology, science, technology and culture.
However, under certain circumstances, speech turned out to be imperfect. Our voice range is limited and human memory is unreliable. How to preserve information for future generations or transfer it to a greater distance? The first symbols known today from rock paintings appeared 40 thousand years ago. The most famous of them come from the caves of Altamira and Lascaux. Over time, the drawings were simplified and turned into pictograms, accurately displaying written objects. They began to be used in the fourth millennium BC in Egypt, Mesopotamia, Phoenicia, Spain, France. They are still used by tribes living in Africa, America and Oceania. We also return to pictograms - these are emoticons on the Internet or the designation of objects in urban space. The magazine that we know today was created simultaneously in different countries of the world. The oldest known example of the alphabet dates back to around 2000 BC. It was used in Egypt by the Phoenicians, who used hieroglyphs to write consonants. The next versions of the alphabet from this evolutionary line are Etruscan and then Roman, from which the Latin alphabets that we use today are derived.
The invention of writing made it possible to write thoughts more accurately and on smaller surfaces than before. First, they used animal skins, stone carvers, and organic paints applied to stone surfaces. Later, clay tablets, papyrus were discovered, and, finally, paper production technology was developed in China. The only way to disseminate the text was its tedious copying. In medieval Europe, books were copied by scribes. Sometimes it took years to write one manuscript. It was only thanks to the machine of Johannes Gutenberg that typography became a technological breakthrough. This allowed a quick exchange of ideas between authors from different countries. This allowed the development of new theories, and each of them had the opportunity to spread and perpetuate. Another revolution in writing tools was the invention of computers and the advent of word processors. Printers have joined the printed media, and books have been given a new form - e-books. In parallel with the evolution of writing and printing, methods of transmitting information over a distance also developed. The oldest news about the existing courier system comes from Ancient Egypt. The first post office in history was created in Assyria (550-500 BC). The information was provided using a variety of transport options. News came from pigeons, horse-drawn couriers, balloons, ships, railroads, automobiles, and airplanes.
Another milestone in the development of communication was the invention of electricity. In the 1906 century, Alexander Bell popularized the telephone, and Samuel Morse used electricity to send messages over a distance by telegraph. Shortly thereafter, the first telegraph cables were laid along the bottom of the Atlantic. They shortened the time it took information to travel across the oceans, and telegraph messages were considered legally binding documents for commercial transactions. The first radio broadcast took place in 60. In the 1963s, the invention of the transistor led to portable radios. The discovery of radio waves and their use for communication made it possible to launch the first communications satellite into orbit. TELESTAR was launched in 1927. Following the transmission of sound over a distance, tests began on image transmission. The first public television broadcast took place in New York in 60. At the beginning of the XNUMXth century, thanks to radio and television, sound and image appeared in millions of homes, giving viewers the opportunity to touch the events taking place in the farthest corners of the world. the world together. In the XNUMXs, the first attempts to create the Internet were also made. The first computers were huge, heavy and slow. Today allows us to communicate with each other in a sound, visual and text way at any time and in any place. They fit phones and watches. The Internet is changing the way we function in the world.
Our human natural need to communicate with others is still strong. Technological advances may even give us an appetite for more. In the 70s, the Voyager probe set off into space, equipped with a gilded plate with earthly greetings to other inhabitants of the universe. It will reach the vicinity of the first star in millions of years. We use every opportunity to let us know about it. Or maybe they are not enough and we do not hear the call of other civilizations? "Hello Earth" is an animated film about the essence of communication, made in full-dome technology and intended for viewing on a spherical planetarium screen. The narrator was played by Zbigniew Zamachowski, and the music was written by Jan Dushinsky, the author of the musical score for the films Jack Strong (for which he was nominated for the Eagle Award) or Poklossie. The film is directed by Paulina Maida, who also directed the first film of the Copernican Heaven planetarium, On the Wings of a Dream.
Since April 22, 2017, Hello Earth has been included in the permanent repertoire of the Heavens of Copernicus planetarium. Tickets are available at.
A new quality in the sky of Copernicus Come to the planetarium and plunge into the universe like never before! Six new projectors deliver 8K resolution – 16 times more pixels than a Full HD TV. Thanks to this, Heaven of Copernicus is currently the most modern planetarium in Poland.
