GOD IN ANCIENT TIME.
PEOPLE THROUGH THE AGES HAVE WORSHIPED THE SUN AS THE SOURCE OF LIGHT,AND THEREFORE,AS THE SOURCE OF ALL LIFE.OUR ANCESTORS REALIZED THAT IF THERE WAS NO SUN,THE EARTH WOULD BE PLUNGED IN PERPETUAL DARKNESS.IT WOULD BE UNBEARABLY COLD,AND ALL THE WATER ON EARTH WOULD FREEZE UP
ANCIENT CIVILIZATIONS PRIMARILY AGRICULTURE, AND DEPENDED ON THE SUN FOR THERE LIFE AND CROPS.THEREFORE,IT NO SURPRISE THAT THEY WORSHIPED THE SUN AS A GOD.
LIGHT
WE ALL KNOW WHAT LIGHT IS.WE ALSO KNOW THAT THE SUN,FIRE,BULBS AND GLOW WORMS ALL GIVE US LIGHT. BUT WHAT EXACTLY IS LIGHT.
LIGHT IS A FORM OF ENERGY THAT WHICH WE CAN SEE.IT IS MADE UP OF BILLIONS OF TINY PARTICLES CALLED PHOTONS.THESE PHOTONS TRAVEL FROM ONE PLACE TO ANOTHER IN WAVES.
THE LIGHT THAT WE CAN SEE CONSIST OF PHOTONS THAT MOVE AT A WAVE LENGTH THAT MAKES IT VISIBLE,AND IS KNOWN AS VISIBLE LIGHT.
AGRICULTURE IN STONE AGE
ON OCCASIONS,WHEN MEN WENT OUT FOR HUNTING THE WOMEN WHO GATHERED VEGETABLES AND FRUITS MAY HAVE BROUGHT BACK THE SEEDS.THEY WOULD HAVE SEEN THAT THESE SEEDS WHICH THEY THREW INTO THE SOIL AROUND THEIR DWELLING PLACES SPROUTED,BECAME PLANTS FLOWERED AND BORE FRUITS WHICH TURNED RIPE AND COULD BE EATEN.AFTER ACQUIRING SUCH KNOWLEDGE HUMANITY MIGHT HAVE VERY GRADUALLY STARTED CULTIVATING AND PRODUCING FOOD CROPS.
NANOTECHNOLOGY IN AGRICULTURE.
THE USE OF NANO MATERIAL IN AGRICULTURE CAN REDUCE COST AND EFFORT,INCREASE EFFICIENCY,AND LEAD TO A BETTER ENVIRONMENT.
NANO MATERIALS ARE BECOMING AN INCREASINGLY IMPORTANT ISSUE IN AGRICULTURE,PARTICULARLY AS ADDITIVES OR AGENT IN FERTILIZER,OR PLANT PROTECTION PRODUCTS.IN THE CASE OF PESTS OR DROUGHTS NANOTECHNOLOGY MAKE IT POSSIBLE FOR AN AUTOMATIC ADJUSTMENT OF PESTICIDE OR IRRIGATION LEVEL,TO COUNTER THESE CHALLENGES.
MILESTONE NANOTECHNOLOGY
THE FIRST IMPORTANT MILESTONE NANOTECHNOLOGY OCCURRED IN 1985 WITH THE INVENTION OF 'BUCKY-BALL' OR CARBON 60 MOLECULES,BY A GROUP OF SCIENTISTS.
IN 1988, SOME SCIENTISTS PROVED THAT IT IS POSSIBLE TO MOVE ATOMS AND MOLECULES IN A PLANNED MANNER.THE NEXT IMPORTANT STEP WAS THE INVENTION OF THE CARBON NANO TUBE IN 1991.
NANOTECHNOLOGY.
NANOTECHNOLOGY IS A WONDERFUL NEW TECHNOLOGY IN WHICH SCIENTISTS REARRANGE ATOMS AND MOLECULES OF MATTER TO NANO SPECIFICATION.OR,TO PUT IT DIFFERENTLY,THE USE AND CONTROL OF TINY MATTERS IS CALLED NANOTECHNOLOGY.
THE TINY MATTER IS REFERRED TO US NANO PARTICLES.THIS PARTICLES ARE MEASURED IN NANOMETERS.MATTER AT THE NANO SCALE HAS DIFFERENT PROPERTIES FROM THE SAME MATTER IN THE BULK FORM.
NUCLEAR ENERGY.
NUCLEAR ENERGY IS THE ENERGY IS THE ENERGY IN THE NUCLEUS.ATOMS MAKE UP EVERY THING IN THE UNIVERSE,AND ARE HELD TOGETHER WITH GREAT FORCE.
IN A PROCESS CALLED FISSION,ATOMS ARE BROKEN APART,AND ENERGY IS RELEASED.ATOMS OF URANIUM,A COMMON ELEMENT THAT CAN BE MINED FROM THE EARTH,ARE USED IN NUCLEAR REACTORS.
EUROPEAN EXPLORATION.
THE ABORIGINES WERE THE NATIVES WHEN THE FIRST EUROPEAN ARRIVED THERE.
THE ABORIGINAL PEOPLE HAD THEMSELVES ARRIVED IN AUSTRALIA FROM ASIA AROUND 40,000 YEARS AGO. THEY HAD PROBABLY WALKED ACROSS A LAND BRIDGE.SLOWLY BUT SURELY, THEY SPREAD ACROSS A NEW CONTINENT.THESE NOMADIC HUNTERS AND GATHERERS LIVED IN SMALL GROUPS
KANATA TO CANADA.
JACQUES CARTIER CARRIED OUT THREE EXPEDITIONS TO CANADA IN 1534,1535,AND 1541. THE FRENCH EXPLORER FOLLOWED HIS DREAM OF FINDING A NORTHWEST PASSAGE TO THE PACIFIC THROUGH NORTH AMERICA.HOWEVER HE FAILED TO FIND IT.BUT HE BECAME FAMOUS FOR NAMING CANADA.CARTIER PAVED THE WAY FOR FRENCH EXPLORATION OF NORTH AMERICA.HE SAILED INLAND,SIXTEEN HUNDRED KILOMETERS UP THE ST.LAWRENCE RIVER. 'KANATA' MEANS VILLAGE OR SETTLEMENTIN THE HURON-IROQUOIS LANGUAGE.
TROPICAL RAINFORESTS.
TROPICAL RAINFORESTS ARE FORESTS WITH TALL TREES,WARM CLIMATES,AND LOTS OF RAIN. THESE FORESTS ARE FOUND JUST ABOVE, AND BELOW THE EQUATOR.
TROPICAL RAIN FORESTS HAVE A HIGH LEVEL OF BIOLOGICAL DIVERSITY OR 'BIODIVERSITY'. BIODIVERSITY IS THE NAME FOR ALL LIVING THINGS.
STORY OF OUR CRADLE
FOREST WAS THE CRADLE OF MAN. IT FED HIM WITH FRUITS AND VEGETABLES,CLOTHED HIM WITH LEAVES AND BARKS,AND SHELTERED HIM WITH BUSHES AND CAVES.FOREST TAUGHT HIM TO SAW SEED ,TO REAP CROP ,AND TO HUNT GAME. ALL HE REALLY NEEDED TO LEARN, HE LEARNT FROM THAT KINDERGARTEN. BUT AS MANKIND DEVELOPED, FOREST BECAME A LABILITY.
