THE WHEEL
BEFORE THE INVENTION OF WHEEL IN 3500 BC HUMANS ARE SEVERELY SUFFERED FROM TRANSPORTING OVER LAND.INVENTING THE WHEEL WAS NOT A DIFFICULT ONE SAID DAVID ANTHONY, THE PROFESSOR OF ANTHROPOLOGY AT HARTWICK COLLEGE.THE WHEEL WAS INVENTED BY MESOPOTAMIAN CIVILIZATION BY INSERTING A ROTATING AXLES INTO A SOLID WOOD.THEN IT IS SLOWLY MODIFIED AND USED FOR AGRICULTURAL AND FOR LONG DISTANCE TRAVEL.
WITHOUT NAILS CIVILIZATION WOULD SEVERELY CRUMBLE . IT WAS INVENTED BEFORE 2000 YEARS. ON ROMAN CIVILIZATION PERIOD . AFTER THAT INVENTION USING THE METHOD MAKING NAIL THEY MADE AN EASY METHOD AND MADE HUNTING TOOLS ALSO ON THIS METHOD.
ANCIENT MARINERS NAVIGATED BY STARS BUT USING THIS METHOD DID NOT WORKED WELL DURING THE DAYS AND CLOUDY TIMES OF TRAVELLING.THEN CHINESE INVENTED THE FIRST COMPASS IN BETWEEN 9TH AND 11TH CENTURY .IT WAS MADE OF LODESTONE A NATURALLY MAGNETIZED IRON ORE .LATER THE COMPASS HELPED TO INCREASE SEA TRADE.
MANY OF THE SCIENTISTS TRIED TO INVENT TELEPHONE BUT DUE TO SOME ELECTROMAGNETIC PULSES IT EXPLODED.BUT ALEXANDAR GRAHAM BELL WAS AWARDED THE PATENT FOR ELECTRIC TELEPHONE IN 1876.THIS INVENTION IMPROVED GLOBAL BUSINESS AND COMMUNICATION.
IT NOT NEEDS ANY INTROS WE ALL KNOW THAT .GLOBAL SYSTEM OF INTERCONNECTED NETWORKS KNOWN AS INTERNET.MANY PEOPLES HAVE HELPED IN DEVELOPING IT, BUT THE PERSON WHO CREDITED IS THE COMPUTER SCIENTIST LAWRENCE ROBERTS.NOW , A MAN WITHOUT INTERNET IS A VERY RARE ONE.
