telephone communication

Over time, Earth has always had a role in the development of communication technologies. Today, satellites and the Internet allows instant and long distances, while watching that Earth scientists in the future to continue to play a vital role in achieving communication.
People communicate in different ways: through facial expressions, through body language such as, for example, tightening of hand, which sounds like laughter, or screaming. People communicate and more complex means, through language, verbal expression including both car and written expression through images, through music.
Nowadays, communication has as support various forms, from books to magazines and newspapers, radio and TV phone, computer discs, tapes. But for centuries among the communication involved movement and difficult access areas such as mountains, deserts or large expanses of water constitute barriers to communication. Oral messages could be changed, forgotten or simply hard to understand. Nobody knows exactly when they began to form language, but today there are over 3,000 main languages in the world, plus their dialects. But it could have been much more substantial to be extinguished over time.
With the development of writing, sending messages to remote become safer and at the same time simpler. In this way the risk is that messages not be forgotten, and the signature or pecetele reassurance. The ancient Egyptians were not aware that was the first who began to strike a balance environmental defrisand huge areas of papyrus.
Meanwhile the discovery of new territories, began to be reflected in the landscape change. Intinsurile of glaciers or deserts tundra were less interesting. Civilizations developed based on communication, the most fertile areas in the plains, along rivers and the coast, where he lives today more than three quarters of the world population.
Among the most populated areas was situated the mountain passes, strategige points in time of war or mass migration. Khyber Pass between Afghanistan and Pakistan has been for centuries among a gateway linking Europe and the Middle East the Indian subcontinent. The scene of many important battles, this pass was crossed by explorers and traders, riding camels saumai then using railways and roads.
Written communication has developed rapidly. In China and Japan were produced molds printed symbols since 1000i.Hr. At first books were for only the privileged. Pigments or inks were extracted from soil or plant. Around 1447, Gutenberg invented Johaness German metal band printed furniture, which led to an explosion of written communication. Bye whole began to be rough cut for paper production, a phenomenon which continue today, but in a controlled but significant effects on relief. Time allocated huge areas in North America, in Scandinavia, in Northern part of Asia and parts of South America for the cultivation of special species of trees for paper production.
A remote communication fast, efficient and safe was not really possible until 1820. The landscape was further changed due to new methods for construction of tunnels and viaducts. Crossing water remains a stumbling block to communication, the only method in this respect remained shipped.
The next great leap in the development of communications began with the invention the telegraph, in 1837 by Englishmen Charles Wheatstone and William Cooke, continues in the 1840s by Samuel Morse code invented by him and then the telephone invention in 1837 by Alexander Bell Grahan . Now Spoken messages could be transmitted spontaneously pritr a cable. At this time began the development of the telephone wires with the installation and their barriers at putim relief became more important. No great stretch of water is no longer a problem, because installing a subsea lines, the first transatlantic cable was installed in 1866.
Another important date in the history of development communication is a wireless radio transmission, by Guglielmo Marconi. This system requires installation on poles, towers and high on the hills, instead of wires, towers and receivers of which captures electromagnetic radio signals.
Transatlantic wireless messaging, Marconi installed a transmitter in the district of Cornwall in England, and up the St. Jones of Newfoundland, which has reduced transatlantic distance, considering the curvature of the globe and at 2700 km, normal distance, measured between two centers of population is 4,000 km.
Since the launch of the first space satellite, Sputnik, in 1957, the beginning was space, which brought hundreds of communication satellites, changing techniques of radio transmissions, TV and telephone in intreagalume.
With all these discoveries of mankind, the Earth continues to play an important role in communication by gravitational force that attracts all these satellites, maintaining its correct orbit. Rockets to launch satellites are detached to the East, the direction the Earth rotates, which help achieve the correct orbital speed. No doubt scientists will continue to seek ways in which the Earth can contribute to the development of human communication in the future.

How a conversation must take place

rules for successful conversation The danger that threatens any meeting, around the family table and select the reception, is boredom. Surest remedy against it is the conversation. What is the secret conversation? There put up a perfect recipe that ensure success in all situations? No, unfortunately! You can enter a date in this area that gives some opportunity to conduct the full power of seduction, and others to commit mistake after mistake. Aridity between boredom and danger ridiculului must follow a path whose main steps are tact, discretion, attention, enthusiasm, humor, culture, politeness and honesty. Appear here as in almost all manifestations of life in common, at least two wrong attitudes. There are some very reliable people on them, which polarize the conversation, drunk themselves with their own words, speaking them relentlessly and forbidding any other participation in the discussion. At the other extreme is situated tacutii, shy, those who fear is a terrible wrong not to say or think about; followers eternal "You're right" or you have new "Right!". Thus we arrive at a situation that sets out a humorist: "In any conversation, there are two kinds of individuals: pisalogii and victims." Art of conversation can not be studied as mathematical formulas. It is acquired more like a foreign language, observe certain rules and practice it endlessly. I will still give some of these rules, but only you are able to decide if they will help you to behave in a pleasant company.
invite only doctors?
No general conversation between ten or twelve people may not extend long time. Therefore, one has to host guests and groups by certain criteria. At this should think about since when do the invitations. You will find that most successful meetings are those in which the guests have the same occupation or same hobby. If physicians will address are undoubtedly matters of common interest, that is medical. Also, if you only invite teachers and, moreover, they are colleagues from the same school, the discussion revolves around the job will be draining all their thoughts. Imagine if in error - for it is a mistake - we invited a couple of engineers and two business people. Clearly, they will feel isolated and be bored to death. After an hour or two, will invent a reason to leave. Certainly not interested in any gossip in the office and even cancer prevention, for example, which were discussed with the fire all night.
Guests of various professions
But social life puts us in the situation and to have relationships with people from different fields with different interests. Therefore, many times, we are hosts of parties where assistance is heterogeneous. Our obligation is to present and engage in discussions on the pleasant, accessible to all. He dreams not seem an exaggeration, but our role, when we are hosts, not far from that of a director. Professional subjects should not take over the conversation, because its purpose is another - is to learn new things, of interest. Therefore we take care to not group the table who have the same job. The conversation may well start with it on a really diverse and reach general considerations on the eternal problems of life.
taboo and blunders
There are topics that can be discussed only between friends. One of them, and not least important, is the money. If it is allowed to talk at a party about the price of a journey is a mistake to talk about the price of a gift. Such blunders make us recognize them came from a post. But bad taste is the height you complain of lack of money, family troubles or at work. Furthermore, e and useless - no one will solve your problems. You have only pitied and you put in an embarrassing situation. All gang is like a party to ask advice someone with a certain job. No banker will not show your best investment for your money only because it is called in the same house with you. Nothing will compel you to give information on the bank to buy them with hard cash. The worst of all are sick forever, for which a consultation is welcome any time, forgetting that no one doctor can not diagnose in such conditions. In addition, no one will be happy to give advice in his spare time. If you have some, could react Viennese doctor known for his answers given during a soirees at which a consultation was asked: "With pleasure, Madam, would you dezbrocati!" Almost every doctor, lawyer or teacher can relate to one or two Intresting that illustrate the anger of many people to mix professional life with free time when they are in a society. Money worries or family professional counseling so any issues are avoided. Other taboo subjects are politics and religion, both too strongly linked to the views outlined in the human mind to be changed to a risk of meeting some far reaching argument. And one, and keep the training and other human intellect, sometimes varying enormously from one person to another. However, in case of heated discussion, to follow the example of those who lose their temper. Meanwhile, the role of the host or in its absence, the other guest is to change the subject. To remember, in conclusion, successful way of a party depends on the talent to choose guests. It was not our ambition to call at once on all our acquaintances belong to totally different environments, just to get rid of some obligations. Let's be careful and at the age of the guests. When do the invitations, each guest is good to mention who else comes to hand.
to know how to listen
We must always be careful what you are told, so do not put your interlocutor to inferiority, even if you are more educated and more informed than he. That does not mean you have to always give him the right of another. However paradoxical it might seem, in this "game" can gain a reputation cozeur brilliant. Why? For the know to listen is an art, as the refrain was always giving advice is a proof of wisdom.
deaf dialogue
It is well to respect other's opinion, even if different from yours, because it could be based. That does not automatically give up your own opinion and not consider it minor. The subject may remain open, and the only way to clear up the dialogue, provided it does not become a dialogue of the deaf. Nothing prevents you to support the idea in the discussion. But do it without offending your interlocutor. To avoid categorical interventions like "Bullshit!", "No way!", "You cheated" or "What nonsense!". They are a proof of lack of education and conversation may block irretrievably. Give him and the other the opportunity to intervene. Is more appropriate to say: "Pardon me, sir, but the belief is you can talk." However, we do not switch off his interlocutor. He who does not is less guilty than one who talks all the time.
Who are our interlocutors?
To pay attention and who talk. Do not talk to anyone, without discernment, certain subjects, because the risk that our laundress, otherwise a very decent woman, to fill the Fair with our troubles! If it happens we are in a societace composed of individuals with a higher level of training than ours, it is prudent not to open mouth, at least not likely to make us the laugh! I attended sometime in the next randomly funny: in a group of intellectuals complained of lack of space in apartment block, hit a young less educated, who felt entitled to intervene: "Yes, you're right, and in November is crowded in the kitchen, one enters, another leaves - is simply, how to say ... a traffic of influence "young, overwhelmed by the elevated discussion which had taken place until then, found the opportunity to place a" radical "as he says simply.
compliments
Small compliments maintain conversation, maintain friendships as small gifts. It is hypocritical to make a compliment him master of the house on mincarii taste good, even if no-one cooking it. But to tell a woman of sixty years that have taken it as her daughter is not a compliment, but a rudeness. Would be equally wrong to tell your host: "Great this porcelain. I guess it cost a lot! " A begging compliments. The exaggerated compliment is a lack of tact, but are required to be done is a proof of stupidity. Often meet people hungry for compliments, which English expression to fish for compliments (compliments of begging) they fit very well. How to react? We simply avoid the ability to give them, avoiding to be our turn to look gross. Not hungry for compliments will open discussion on a topic that I favor. Neintrind our "game", the discussion will become monologue and our friend will end up alone boasts. There are in all of us tend to our autocaracteriza. Often we hear people who feel duty bound to say: "I am a very fair"; "I am very honest and discreet", "I am very punctual", "I am very good at my job." Wishing to give us the image total "personality" of their complements what they call "flaws": "But I and weaknesses: they are too good, too naive", etc.. Some praise ourselves, denying that they do: "Not that I brag, but I dress very well ..." unbearable beings! Let's leave others to judge us - after the fact, and not after "suggestions" our. This category of people related to present themselves not get trust those around, on the contrary, they arouse suspicion.
